A brief overview of bituminous mastics
To keep from the destructive effects of water and frost, it is necessary to protect the buildings. Here we describe the materials for waterproofing the Foundation and the basement. Protective materials can be very diverse: natural (e.g. clay) and artificial (e.g. petroleum bitumen).
Natural materials are relatively affordable, but not always easy to apply, there are some subtleties. A big plus of these materials - they are of natural origin (natural), but not the correct application can play a negative.
To artificial can be attributed to the coating based on cement and chemical additives, polymer sealants, bitumen roll materials, synthetic membranes and more. The most common are mastics based on bitumen. Ready-to-use formulations designed for specific applications or a wider range of applications.
In our time, with a fast pace of life do not want to experiment with a fire and a bag of bitumen, and directly use the finished composition, developed by professionals and produced in a modern factory. It is not necessary to choose imported expensive materials, overpaying for a big name.
As a rule, the problem of waterproofing is necessary to perform quite standard, choose a super effective tool with a space price tag is not necessary. For the majority of tasks there are mastics on a bituminous basis. Such materials show themselves as reliable hydro-protective compounds for many years.
How to decide what I need
Bituminous mastics have a certain purpose, concrete structure under certain tasks and the corresponding description.
Water-based bituminous mastics are preferable for indoor use, as they do not contain organic solvents.
There are mastics resistant to high temperatures, reflective, filled with aluminum powder.
More elastic rubber-bituminous mastics apply on the surfaces subject to formation of not big cracks or subject to vibrations.
Mastic for the Foundation, thanks to a special formulation well adheres to the concrete, closes the pores and resists water.
How and what to apply
Depending on the situation, area, availability of tools and equipment - it can be a brush, roller, spatula or spraying with a special gun. In private housing use simple brushes and rollers.
Before applying the mastic, it is sometimes advisable to ground the surface with a primer on a bituminous basis, then apply the mastic in one or more layers.
