Mastic asphalt roofing hot and cold - set difference

Mastic asphalt roofing hot - characteristic composition

bitumen solutions for critical reception technology.If it is based on the use of (gleaned in each case) formulations of solvents, then it comes to the cold solution.As solvents can be used gasoline, kerosene, alcohols, etc. TechnicalCold compositions have better fluidity and penetration.In addition, they quickly solidify.For

hot solutions characterized by heating technology for producing various techniques (flame, heating, etc. in the tank.).An example may be hot solutions roofing mastic.Its main purpose is the gluing of flexible roofing materials on the basis of the same bitumen, creating a waterproofing plastering on structural elements.

For applying the composition requires heating to a temperature of about one hundred and eighty degrees.The hot composition is smeared or applied in any other way on the ground.High adhesiveness and fluidity in a heated condition provides strong adhesion and good protection of the surface coating.

obvious disadvantage of working with hot mastic will need additional equipment for its heating.The complexity of the work increases outdoors in cold conditions.

In this case, the low temperature of the substrate does not provide a high quality solution clutch and roofing materials, or the formation of a reliable waterproofing layer.

Cold mastic - unpretentious replacement for construction

Unlike hot roofing mastic asphalt cold prepared, like all cold solutions, using different solvents.It can be used to perform work without the need for additional heating, in the "field" conditions, such as at a construction site, even in winter.

The thing is, a solvent is selected for its preparation.As becomes clear cooking cold mastics possible using gasoline, kerosene or other solvents.In practice, the most commonly used oil solyarovoe.Its

heated during preparation of the composition and introduced into the bitumen melt with excipients (usually lime and asbestos).Thus obtained can be used in the composition of the works carried out or stored in a sealed container (a prerequisite).

compare hot and cold option - which is better?

as checking properties of the resulting composition of the cold bituminous mastics used bonding the two layers of a conventional roofing.Testing is carried out only one day after gluing.Besides adhesive ability, cold mastic should not impair the properties of bendability and elasticity.When applied to a substrate, it should form a homogeneous layer with the heat resistance is not worse than that of the hot mastic.

All cold mastic can be divergent characteristics, roofing mastic asphalt hot here serves as a reference point.That compared with its manufacturer is experimenting with the recipe gets uncharacteristic cold properties, it aims to make comfortable, but a lightweight material.

We must bear in mind that with decreasing temperature, the oil tends to thicken.This can have a negative effect on these characteristics.But, in general, cold mastics convenient to use.With their help, you can easily stick a soft roof in the form of rolls, to apply a waterproofing protective layer, arrange a vapor barrier, etc.

When using mastic their application is carried out on a pre-cleaned dry surface.We do not recommend their use as an independent electrically insulating coating or anti-corrosion, etc.
