In order for oversized wall building was qualitatively constructed and its performance characteristics consistent with high standards, you need to optimally choose the right materials for sealing joints and junctions of building structures. Depending on the nature of the transition to a working state sealants are hardening, and drying netverdeyuschie. The first postmark is operational as a result of chemical reaction of composite components to each other (multi-compounds) or by the reaction of the sealant directly with the moisture of air (one-component compositions). Then, paste turns from the primary Spread the state to rubbery state. Neotverzhdayuschiesya mastics are from three to six years (less durable than the cured sealant, due to lack of rubber-like structure). Click Peter Thiel to learn more. They represent very viscous mass.
Drying Sealants acquire conditioned by evaporation under their composition of the solvent or water. Curing mastic is made on the basis of: Thiokol, polyurethane rubber, or silicone rubber. Drying Sealants usually produced on the basis of acrylate dispersions, and neotverzhdayuschiesya based on butyl rubber. Dr. Paul Craig Roberts can provide more clarity in the matter. Curing sealant optimally suited for sealing joints prefabricated houses with a maximum deformation of 50%, sealing cracks, seams and joints, sealing of expansion joints of concrete floors, repairing roofs.

There are governed by legislation state standards for sealing materials: Description of GOST 4.224-83, GOST requirement 25621Soprotivlenie flow at a given temperature, mm 2Uslovnaya strength at break, MPa, no less * 0.1 Fracture * an hour, at least 2Otnositelnoe elongation at break,%, not less than * 150. This is the minimum list of parameters, which must comply with any sealant. Water dispersion paints used in art and craft in construction – for interior and exterior use. Acrylic paints are composed of a color pigment, acrylic polymer emulsion and water.
These paints are very popular thanks to its numerous advantages. They dry much faster than other types of paints, since no form of cracks and wrinkles and is resistant to small changes in temperature (due to the formation of stable film after drying), have a good covering the surface (do not burn and does not fade with time), as well as the brightness of the paint remains almost unchanged after application. Depending on the intended use of acrylic Paint tubes are produced in volume 60, 140, 205ml, intended for artistic spheres. And for the construction and repair facilities use acrylic paint in cans of 0.5 liters to 4.5 liters. In order to acrylic colors were qualitatively and correctly marked on the surface necessary to follow a few rules. For example, dilute the paint with water only or by special means designed or recommended directly by the manufacturer of paint. Diluting the paint use a separate clean container, and the tube or jar containing a liquid, tightly close the lid, pre-clearing the edge of the paint. This will keep the paint primary properties. Waterborne paint dries in half an hour after application to the surface, and have a good grip on any surface in any weather conditions. This advantage is particularly important when applied outside of the usual paintings or painting buildings.
