How dry sealant and how to work with him ?

features like sealants materials

Modern building technologies are increasingly using all kinds of sealants, materials, allowing easily reliably to seal joints, cracks, hide and isolate the small and minor defects.Efficiency and application adaptability makes them indispensable in many occupations, such as insulating responsible jobs.

All sealants provide high strength and resistance to deformation, have high adhesion, elasticity and durability in operation (both inside and outside structures).Used in modern sealants formulations contain polymers (polysulfides and liquid silicone rubbers), they provide a simple application of the sealant.As a rule, release of single-component formulations manufacturer does in special tubes.

This package allows you to squeeze a lot of mechanical (pistol used by other devices) through special cone nozzle to fill the space.This technology is often not required trowel sealant.

Although fluidity and adhesive properties of most of the compositions allow to obtain a smooth opaque layer, if necessary, the surface structure can be aligned with an appropriate tool.

What to remember when starting to work?

clear that the willingness to use - this is one of the factors determining how to use a sealant.If one-component formulations ready for use immediately after the release, the multi demand preliminary preparation with the need to comply with the exact proportions of mixing and curing technology specified by the manufacturer, before sealant use.Only in this case, adhesion is guaranteed all the physical, chemical and mechanical properties.Furthermore

ready for use, and the compositions may vary in chemical composition.Here there is a great variety: there are silicone-based, acryl polymer, polyurethane, based on butyl polymers, based on bitumen.Clearly, these features determine how to apply the sealant on the surface.

Continuous development and improvement of production technologies of these compounds makes it possible to apply sealants in detail and elements of engines at high temperatures and aggressive environments.Each type has a specific field of application.Thus, for example, acrylic recommended for use when working inside and can not withstand outdoor use.

How to work with a sealant?

perhaps, are the most versatile by widespread silicone sealants.They provide high performance and long life operation.Good adhesion is responsible for the reliability of the layer even on the glass or glazed wall tiles.When testing the silicone sealants destroyed rather the seam rather than the contact plane with sealable materials.

All activities have their own little secrets.And how to properly use a sealant, as there are nuances.For example, when sealing seams to ensure a long and reliable service life ratio of the depth and width of the joint should not exceed two to three.

If joint depth exceeds (in most cases it is), in the pre-seam tightly inserted into special plastic cord.If necessary, it is easy to produce from a conventional plastic bag or a plastic bag.At sufficiently wide to eliminate seam sealant adhesion to the three planes is enclosed strip of polyethylene.

In conclusion, I must say that before use the sealant, the surface should be carefully prepared.They are cleaned, degreased, if necessary (depending on the material) should be primed with a special compound.

special trowel sealant (its width must correspond to the width of the treated joints) are used to obtain a smooth seam surface.For the same screed special formulations and sprays can be used.
