Битумная мастика как наносить: Битумная мастика холодного применения — как использовать?

Как обработать дерево битумной мастикой своими руками

Древесину можно по праву назвать одним из лучших строительных материалов. Удобство работы и универсальность позволяют нам использовать дерево практически для всего. Ну а такие недостатки, как подверженность огню, влаге, плесени и вредителям, а также прочим вещам можно исправить при помощи средств обработки. И одним из таких средств является мастика на основе битума или воска. В этой статье мы остановимся на ее описании, методах нанесения и даже способов самостоятельного изготовления.

Преимущества, которые дает использование мастики

Гидроизоляция — это главный плюс использования мастики и основное ее предназначение. Использование этого обрабатывающего материала позволяет повысить стойкость дерева к износу, улучшает его эстетические характеристики, упрощает дальнейшую уборку  и многое другое. Полы, защищенные данным составом, получают защиту от вредителей. С той же целью мастикой обрабатывают и другие деревянные поверхности.

Однокомпонентная и двухкомпонентная мастика

Однокомпонентная. Готовый к нанесению раствор, без необходимости разведения или проведения прочих манипуляций. В этом проявляется простота работы, так как можно не затрачивать время на подготовку. Недостатком является то, что после открытия емкости покрытие начинает затвердевать, и та мастику, которую мы не использовали, в будущем станет бесполезной.

Двухкомпонентная. Как и понятно из названия, данный вид мастики представляет собой два компонента, которые смешивают в нужных пропорциях, превращая таким образом в готовую для работы смесь. По отдельности компоненты могут храниться очень долго, так что этот тип мастики куда более экономичный.

Холодная и горячая мастика

Холодная. В основе смеси лежат различные химические растворители, такие как уайт-спирит.  На полное высыхание покрытого такой мастикой пола обычно требуется несколько дней. Причем, все это время в помещении будет стоять сильный химический запах, который не только неприятен, но и опасен для здоровья. Так что желательно все же не заселять помещения в течение нескольких дней.

Горячая. Мастика, созданная на основе битума или каучука. Перед использованием ее необходимо прогреть, доведя до нужной температуры и консистенции. Температура эта, к слову, достигает 180 градусов по Цельсию. Так что работать с таким составом необходимо максимально аккуратно, дабы не получить ожоги. Внимательным необходимо быть еще и потому, что состав пожароопасен. Преимуществом такого состава является то, что он очень быстро застывает – вплоть до нескольких минут.

Преимущества битумной мастики

Битумная мастика может сделать ваш пол или иную деревянную поверхность блестящей по причине того, что в некоторых ее видах содержится воск. Некоторые виды такой мастики содержат в себе водоэмульсионные компоненты, позволяющие мастике быть твердой, жидкой и даже в форме своеобразной пасты. Наконец, в битумной мастике имеются компоненты, которые значительно облегчают удаление грязи, так что убирать такие полы будет гораздо проще.

Чем наносить данный материал на поверхность дерева

Мастика, также как и краска, может быть нанесена различными кистями и валиками. Если же необходимо покрыть большую поверхность и технические возможности позволяют, то идеальным вариантом станет распыление. Очистка кисти или валика от данного раствора весьма затруднительный процесс.

Правила нанесения мастики на дерево

• Перед работой необходимо убедиться в том, что поверхность идеально чиста и не содержит на себе старых следов краски или лака;
• Старайтесь наносить мастику как можно более тонким слоем, что снизит время высыхания и улучшит качество покрытия;
• Обычно мастику, если речь идет о битумном растворе, наносят один раз. Однако, в зависимости от задачи, может потребоваться нанесение до трех слоев;
• После нанесения мастику можно отполировать тканью, добившись таким образом блеска;
• В случае с полиуретаново-каучуковой мастикой, полного затвердения не происходит. Материал постоянно остается полужидким. Поэтому его используют либо в помещениях с высокой вибрацией, либо во влажных грунтах. Мастикой с лучшими гидроизоляционными свойствами является именно полиуретаново-каучуковая. Она может растягиваться до 20 раз и вне зависимости от степени движения и прочих факторов не теряет своих изолирующих свойств.

Битумная мастика – прочие сферы применения

Обладая серьезными водоизолирующими свойствами, битумная мастика используется не только в отношении древесины. К примеру, битумная мастика активно  наносится на бетонные конструкции. Правила работы в этом случае следующие:

Как только бетон затвердевает, его зачищают от песка и пыли. После этого, с целью обеспечения лучшего сцепления бетон необходимо обработать битумным праймером. Если данная грунтовка хорошо впитывается в бетон, то лучше всего нанести слой повторно.  После этого можно приступать непосредственно к нанесению мастики, выбрав битумную или битумно-полимерную вариацию. В случае чрезмерной густоты, состав можно разбавить скипидаром.

Создаем мастику своими руками

Покрытие восковой мастикой деревянных полов, в том числе и паркета, помогает не только сохранить стойкость к воде, но и позволяет значительно улучшить внешний вид пола. При этом состав такой мастики достаточно прост, и ее можно приготовить своими собственными руками.

Для этого нам понадобится каранубский либо пчелиный воск, канифоль на основе сосны и живичный скипидар. Соотношение материалов 4х1х1. В ходе приготовления воск и канифоль размельчаются и смешиваются, после чего засыпаются в одну посуду, которая ставится на водяную баню. После растворения, когда смесь станет однородной, в нее заливается скипидар. Остается лишь поставить раствор в холод для придания густоты.

90000 Bituminous coatings 90001 90002 90003 Bitumens have been 90004 defined as mixtures of hydrocarbons of natural or pyrogenous origin or combinations of both (frequently accompanied by their nonmetallic derivatives), which can be gaseous, liquid, semisolid, or solid and which are completely soluble in carbon disulfide. 90005 90002 90003 Bitumens used in the manufacture of coatings are of the semisolid and solid variety and are derived from three sources: 90004 90005 90002 90003 1.90004 Asphalt produced by the distillation of petroleum 90005 90002 90003 2. 90004 Naturally occurring asphalts and asphaltites 90005 90002 90003 3. 90004 Coal tar produced by the destructive distillation of coal 90005 90002 It is customary to classify bituminous coatings by their application characteristics as well as by their generic composition. All of the coatings can be divided into two classes depending on whether or not they require heating prior to application. 90005 90002 90003 1.Hot-applied coatings. 90004 These are either 100% bitumen or bitumen blended with selected fillers. A common loading for coatings employing fillers is 10 to 20% filler. Hot-applied coatings are brought to the desired application viscosity by heating. The majority of buried pipelines are coated with this type of bituminous coating. 90005 90002 90003 2. Cold-applied coatings. 90004 These employ both solvents and water to attain the desired application viscosity. A wide range of solvents is used and the choice depends mainly on the drying characteristics desired and the solvent power required to dissolve the particular bitumen being used.Various fillers are also used in cold-applied coatings to obtain specific applications and end-use properties. 90005 90002 Bituminous coatings can be formulated from many combinations of bitumens, solvents, or dispersing agents and fillers. This makes possible a great variety of end products to meet application and service requirements. The coatings that can be produced range from thin-film (3-mil) coatings to protect machined parts in storage, up to thick (100-mil), tough coatings to protect buried pipelines.90005 90002 90003 As with all other coatings 90004, the conditions of the surface to which a bituminous coating is applied is an important, life-determining factor. A good sandblast is preferred, especially if the surface is badly corroded and the exposure is severe. In any case the surface should be free of moisture, grease, dust, salts, loose rust, and poorly adherent scale. A thin, penetrating bituminous primer can be beneficial on rusty surfaces that can only be cleaned by wire brushing and scraping.90005 90038 End-Use Requirements 90039 90002 The application will dictate which performance properties of a coating should be given greatest consideration. 90005 90038 Service Temperature 90039 90002 Many applications of bituminous coating require a moderate service temperature range, often no greater than that caused by weather changes. However, other applications, such as coatings for chemical processing vessels, may require much wider service temperature ranges. In any event, it is possible to obtain good performance with bituminous coatings over a range of -73 to 163 ° C.90005 90038 Thermal and Electrical Insulation 90039 90002 Bitumens themselves are relatively poor thermal insulators. However, by using low-density fillers, coatings with good insulation properties can be formulated. These coatings both protect from corrosion and provide thermal insulation. An added advantage of the coatings is that the insulating material (low-density filler) is completely surrounded by bitumen and is permanently protected from moisture. Thus, they are not subject to a loss in efficiency (as are conventional insulating systems) from damage or failure of the protecting vapor barrier.90005 90002 Bitumens are naturally good electrical insulators. This is an important consideration in systems using cathodic protection as a complementary corrosion-prevention device. 90005 90038 Abrasion Resistance 90039 90002 Many bituminous coatings need to have high abrasion resistance. Automotive undercoat-ings, for example, need high abrasion resistance because they are continually buffeted by gravel and debris thrown up by the wheels of the vehicle. 90005 90002 Abrasion-resistant coatings are also used to protect interior surfaces of railroad cars or other vessels handling chemical solids or abrasive slurries.90005 90038 Weathering Resistance 90039 90002 Asphalt-base bituminous coatings generally weather better than coal-tar-base coatings. Also, there is quite a wide difference in the performance of asphalt coatings derived from different petroleum crudes. By critically selecting the crude and the processing method, asphalt coatings can be formulated that will weather for many years. 90005 90002 In industrial areas, corrosive solids, solutions, and vapors will affect weathering performance. In general, the resistance of bituminous coatings to corrosive media is equal to that of the best organic coatings.Bituminous coatings have good resistance to dilute hydrochloric, sulfuric, and phosphoric acids as well as to sodium hydroxide. They also have good resistance to solutions of ammonium nitrate and ammonium sulfate. However, they have poor resistance to dilute nitric acid, and most coatings are not resistant to oils, greases, and petroleum solvents. 90005 90038 Mechanical Impact and Thermal Shock 90039 90002 Bituminous coatings generally have good adhesion when subjected to mechanical impact. However, where severe mechanical impact is expected, the coatings should first be field-tested or tested in the laboratory under simulated service conditions.90005 90002 Resistance to thermal shock is an important consideration in coatings used on some types of processing equipment. Laboratory tests in which a coated panel is transferred back and forth between hot and cold chambers can be used to predict field behavior. Bituminous coatings are available that will withstand thermal shock over a temperature range of -51 to 60 ° C. 90005 90038 Types of Coatings 90039 90002 Because bitumens are very dark in color, heavy loadings of pigments are required to produce colors other than black.However, if color is an important consideration, certain colored paints, including whites, can be used as topcoats. Granules can also be blown into the coating before it has completely cured to produce a wide range of decorative effects. 90005 90038 Thin-Film Coatings 90039 90002 Coatings less than 6 mils thick are arbitrarily included in this group. For the most part, these are solvent cutback coatings. They are black except in the case of aluminum paints employing bituminous bases. The coatings are inexpensive and can be used to give good protection from corrosion when color is not important.90005 90002 Asphalt coatings of this type are used extensively to protect machined parts in storage. Because the coatings retain their solubility in low-cost petroleum solvents even after long weathering, kerosene or similar solvents can be used to remove a coating from the protected part just prior to placing it in service. Coal-tar-base coatings are much more difficult to dissolve and can not be used for this purpose. However, this property makes coal tar useful for protecting crude-oil tank bottoms and in other applications requiring resistance to petroleum fractions.90005 90038 Industrial Coatings 90039 90002 Heavy-bodied industrial coatings incorporate low-density and fibrous mineral fillers. Coatings can be formulated that will not slump or flow on vertical surfaces when applied as thick as 250 mils. However, they are usually used in thicknesses from 6 to 120 mils. 90005 90002 The coatings are used extensively in industrial plants to protect tanks and structural steel from such corrosive environments as acids, alkalis, salt solutions, ammonia, sulfur dioxide, and hydrogen sulfide gases.90005 90002 Industrial coatings are also used in large volume by the railroad industry. Complete exteriors of tank cars carrying corrosive liquids are often coated and provide good protection of the saddle area where spillage is likely to occur. Coatings on the exteriors and interiors of hopper cars in dry chemical service also provide protection from both corrosive action and abrasive wear. 90005 90002 Railroad car bituminous cements are used to seal sills and joints in boxcars. An application of this material followed by an overcoating of granules makes an excellent roofing system for railroad cars.90005 90038 Coatings for use over insulation 90039 90002 Practically all industrial insulating materials must be protected from the weather and moisture; otherwise they would lose their efficiency. Bituminous coatings formulated to have low rates of moisture vapor transmission give best results on installations operating at low (-73 ° C) to moderate (82 ° C) temperatures. Coatings that allow a higher rate of moisture transmission (breathing type) are needed to protect the insulation on systems operating at 82 ° C and above.This is necessary so that moisture trapped beneath the coating can escape when the unit is brought to operating temperatures. 90005 90038 Thermal Insulating Coatings 90039 90002 Low-density fillers can be employed in bituminous mastics to produce coatings with relatively good insulating values; a k value of 0.6 Btu / ft2 / h / ° F is typical. Insulating coatings are usually applied somewhat more thickly than conventional mastics to obtain the insulating value desired. They are commonly used in thicknesses of 250 to 375 mils and because of their thickness and resiliency they have excellent resistance to mechanical damage.90005 90038 Automotive Underbody Coatings 90039 90002 These are mastic type coatings containing fibrous and other fillers. They are used to coat the undersides of floor panels, fenders, gasoline tanks, and frames to protect against corrosion and provide sound deadening and joint sealing. 90005 90002 The coatings have high resistance to deicing salts, moisture, and water. They also have sound-deadening properties that noticeably reduce the noise level inside an automobile. This provides for a more pleasant and less-fatiguing ride.The sealing and bridging action of the coatings is also especially effective in reducing drafts and dust infiltration. 90005 90038 Sound-Deadening Coatings 90039 90002 High-efficiency, sound-deadening coatings can be formulated from selected resinous bases and high-density fillers. They have better sound-deadening properties than automotive under-body coatings and are used on the wall, roof, and door panels of automotive equipment where sound deadening is the primary need, rather than abrasion resistance or protection from corrosion.They are also used on railroad passenger cars, house trailers, stamped bathtubs, kitchen sinks, air-conditioning cabinets, and ventilation ducts. 90005 90038 Pipe Coatings 90039 90002 Industrial coatings are excellent for protection of pipe above ground. However, the environment of underground exposure and the complementary use of cathodic protection make it necessary to use specially designed coatings. The stresses created by shrinking and expanding soil require that the coating be very tough.Rocks and other sharp objects can be expected to cause high localized pressures on the coating surface. A coating must have good cold-flow properties to resist penetration by objects, which can cause localized pressures as high as 690 MPa. 90005 90002 Cathodic protection (an impressed negative electrical potential) is widely used to prevent the corrosion processes from occurring at flaws in the pipe coatings. Both asphalts and coal tars are good electrical insulators and make excellent coatings for cathodic protection applications.90005 90002 Coatings for pipe are usually of the hot application type. Application can be made at the mill, at a special pipe-coating yard, or over the ditch, depending on the terrain, size of pipe, and other factors. The coating may be given added strength by embedding it with a glass fabric while it is still hot. Outer wrappings of rag, asbestos, and glass felts are sometimes used to give added resistance to damage by soil stresses. 90005 90038 Application 90039 90002 Bituminous coatings that are cut back with solvents or emulsified with water can be produced to consistencies suitable for application by dipping, brushing, spraying, or troweling at ambient temperatures.90005 90002 Dipping is usually used to coat small parts. As a rule, coating viscosity is adjusted to produce a thickness of 1 to 6 mils. 90005 90002 Brushing is used on areas that can not be reached by spraying and on jobs that do not warrant setting up spray equipment. Coating thicknesses can range from 1 to 65 mils. 90005 90002 90003 Spraying is the most popular method for applying cold coatings. 90004 The thickness required in one application determines the consistency of the formulation, and thicknesses of 1 to 250 mils are obtainable by spraying.Conventional paint-spray equipment can be used for coatings up to 6 mils thick. Heavier coatings require the use of mastic spray guns fed from pressure pots or heavy-duty pumps. Heated vessels and feed lines can also be used to decrease viscosity and permit faster application and the buildup of thicker films in one application. 90005 90002 Troweling is usually used in inaccessible areas or where it is necessary to produce a very heavy coating in one application. Trowel coats are usually applied in thicknesses above 250 mils.90005 90002 90003 Bituminous coatings can also be applied 90004 hot without the need for any diluents. Such coatings are widely used on piping in thicknesses of about 95 mils. They are heated to 177 to 288 ° C and then pumped into a special apparatus that surrounds and travels along the pipe. 90005 .90000 Chios natural gum mastic. Instructions 90001 90002 90003 Instructions on how to use mastic, how to make mastic powder, dosage of mastic as medicine, etc 90004 90005 90002 You can use mastic as ordinary chewing gum, or you can grind it into powder (or at least in very small pieces) and use it as a natural medicine for peptic ulcers and general for stomach disorders. 90005 90002 Mastic is a 100% natural product. That means that not all the pieces of mastic (or tears as they are called) are the same.Some pieces are bigger, some are smaller, some are harder and some are softer. 90005 90010 90011 Mastic -due to temperature- is softer in summer and harder in winter. 90012 90011 Usually larger pieces are softer than the smaller ones which dry out and harden faster. 90012 90011 Generally, medium or large pieces are better for chewing and small pieces are better for grinding them into powder. 90012 90011 A more yellow colour means older and harder mastic, a more whitish colour means fresher and softer mastic.Generally speaking you should avoid buying yellow mastic, because this means that mastic is very old and has lost some of its properties. 90012 90019 90002 90003 How to chew Chios mastic as chewing gum: 90004 90005 90002 Choose either a small piece, or break a larger piece and use half of it (in any case initially, use less than the total quantity of mastic you intent to chew) and start chewing it. At the beginning is quite hard, but as the mastic gets warmer from the mouth, it gets softer.If the piece you chew is hard then choose a softer piece and add it to the previous mastic in your mouth. Equally, if the initial piece is too soft and gets stuck in your teeth, add a harder piece to make a mixture that will have the right consistency. You could -if you wish- swallow the mastic when you have finished chewing it. Just make sure you cut it in smaller pieces to avoid choking on a large mastic gum piece. 90005 90002 90003 Chios mastic as natural «medicine» * 90004 90005 90002 90031 A.90032 You could either use mastic in 90031 S 90032 mall 90031 T 90032 ears -which is safer for transport- and swallow it as it is, or you could ground it into powder. 90005 90002 90031 B. 90032 Alternatively you may buy ready made mastic powder. 90005 90002 90003 To ground mastic in powder 90004 90005 90002 Get some small tears (small pieces) of mastic. Put it in deep freezer for a couple of hours. While still frozen, put a small quantity in a blender to ground it. Use low speed and do not overdo it because if the mastic gets warm it will stick to the blender.90005 90002 Alternatively for small quantities of mastic you can use a mortar, or for a single dose you can squash some mastic in between two spoons. 90005 90002 90003 Instructions for taking mastic as medicine: 90004 90005 90002 * ATTENTION: These are practical advice, which derives from tradition and experience. It is NOT medical advice. If in any doubt, please consult your doctor. In any case, mastic as a natural product has never shown any side effects even in over consumption.90005 90002 Mastic powder should be preserved either in a fridge, or in a very cool place where temperatures do not exceed 18ο C (64ο F) 90005 90002 The mastic in powder, if exposed to high temperatures will stick together and become one lump, because our powder is 100% natural mastic without chemicals or any other additives that could keep it in powder form. 90059 90031 If the powder sticks and becomes one lump it does not lose any of its beneficial 90032 properties, 90031 or its taste. 90032 In this case, try to tap the jar.If it is in the initial stages of being stuck it could break up in powder again. If the above trick does not work, you could take the powder (lump) of the vase, wrap it in a clean cloth and hit it lightly with a hammer or something heavy until it becomes into powder form again. Alternatively, carefully scratch off powder off the lump with a knife or spoon. 90005 90002 If the powder is very much stuck (if it has being exposed to high temperature) then you might have to put it in a deep freezer for a few hours and then while it is still frozen you can put it in a blender and make it powder again.90005 .90000 Bituminous Mastic — Buy Bitumen Sealant, Joint Sealant, Filling Mastic Product on Alibaba.com 90001 90002 Bitumen-rubber based, elastic mastic used for waterproofing, repairing and adhesion purposes.

SOLUTION 90004 90005 90052 90002 Waterproofing with ISOGUM, plastomeric bituminous membranes, meets the above requirements. ISOGUM is made from a specially formatted mixture of bitumen and polymers from Atactic Polypropylene (A.P.P.), reinforced with polyester fabric. It provides an effective, affordable and easily-applied solution for waterproofing terraces, since it can be stuck down by heating with a blow-torch, without the need of hot oxidised bitumen (bituminous adhesive). 90005 90002 It is suitable for waterproofing terraces at the time of their construction or later. 90005 90002 Where waterproofing is the final surface layer, it is recommended that action is taken for its protection from UV radiation and thus prolongation of the membranes life.This can be done by using bituminous membranes with a covering of mineral chippings (either white or grey) or by the subsequent covering of the waterproofing with an other layer, such as paving slabs or 2-3 cm graded gravel layer, 6-8 cm thick. In the latter case, it is recommended that geotextile is put between the waterproofing and gravel, to protect the waterproofing from «injuring». 90005 90057 90002 90005 90002 90003 III. APPLICATION 90004 90077 90005 90052 90002 90003 Substrate preparation 90004 90005 90084 90085 90002 The substrate should be thoroughly cleaned from any loose particles, grease, dust etc.90005 90088 90085 90002 Any necessary repairs or alterations to the gradient should be carried out using a strong cement mortar (cement: sand = 1: 2 to 1: 3), reinforced by the addition of ADIPLAST polymer latex. It is recommended that bonding of the cement mortar to the substrate is reinforced by applying a bonding layer to which ADIPLAST is also added (cement: sand: ADIPLAST: water = 1: 1: 0,5: 0,5 by volume parts). 90005 90088 90085 90002 Where the terrace intersects the vertical structures a groove must be formed using DUROCRET polymer modified cement mortar or a cement mortar reinforced with ADIPLAST polymer latex.When fast work is required, RAPICRET fast-setting cement mortar can be used instead. 90077 Consumption of DUROCRET: 1,9-2,7 kg / m groove’s length. 90077 This prevents the bituminous membranes from being folded at a right angle, which could result in cracking. 90005 90088 90085 90002 The terrace, which should be dry, is primed with a suitable bitumen primer, such as ISOPAST bitumen emulsion diluted with water or ISOLAC bitumen varnish. 90077 ISOPAST consumption: approx. 0,3 kg / m 90102 2 90103.90077 ISOLAC consumption: approx. 0,3 kg / m 90102 2 90103. 90005 90088 90109 90002 90005 90002 90003 ISOGUM application 90004 90005 90084 90085 90002 The bituminous membranes are heated with a blowtorch and stuck to the surface, starting from the lower points, so that there will be no joints against the water flow. The film covering the inner side of the membrane melts on contact with the flame and facilitates the bonding of the bituminous membranes to the surface. Adjacent membrane felts should overlap each other at a width of approx.10 cm. 90005 90088 90085 90002 Once the bituminous membranes have been laid, the joints are especially treated with a blowtorch and sealed by being pressed with an iron roll, in order to ensure good bonding. Where bituminous membranes with chips is used, the bonding process in the overlapped areas involves a significant loss of chips. To ensure that the coverings ‘protection against UV radiation is adequate, a coating with ISOFLEX is recommended along the entire length of the joints. 90005 90088 90085 90002 The waterproofing is extended about 50 cm up to the sides of vertical surfaces (parapets, stairs, termination etc.), In order to form a watertight basin. 90005 90088 90085 90002 It is recommended that the edges of the bituminous membranes are fixed to the vertical surfaces with aluminium strips, 2 mm thick and 3 cm wide. Galvanised nails and washers are used to fasten them. 90005 90088 90085 90002 The space between the strip and the vertical surface should be sealed with special bituminous mastic ISOMAC. Wherever there is an interruption to the waterproofing (pipes, rain pipes, metal bases etc.), this should be similarly sealed with the same mastic.90005 90088 90109 90057 90052 90002 90005 90057 90052 90144 90057 90052 90002 90005 90057 .
