How to choose a good polyurethane tile glue - the types and characteristics

assortment of adhesives for tile pretty significantly.In view of the basis on which they are made, they are classified into 4 groups.Each is characterized by its own characteristics and the specific application.Let us examine one kind of these products - polyurethane adhesives.

Features material

• Composition polyurethane adhesive - a one- or two-component.In the latter case, the mixture before use is necessary to prepare.This is done by stirring the contents of containers 2, are in the package.
• has sufficient elasticity.
• resistant to almost all chemical compounds, including aggressive.
• Able to effectively bond a variety (including, and heterogeneous) materials - wood, leather, stone, metal, glass and many others, and at this point is really versatile.
• Dehumidification is virtually absent, can withstand significant temperature changes (from -55 ° C to +125 ° C) and pressure.
• provides not only high-quality gluing tiles, but also a solid foundation insulation.Such compounds are considered the most reliable (said to be taken "death") compared to other adhesives.
• Differs fast "strengthening" of the connected interface (joint), which in many cases can significantly accelerate the pace of renovation (finishing) work.
• lack of a specific smell, which is typical for virtually all analog and is considered a significant drawback.

Given this feature of polyurethane formulations as universality, there is a logical question - what the difficulty in selecting such a tile adhesives?Enough to buy, and please, work.But there are some nuances, and you should know about them.

First , all polyurethane formulations, even sold under the same brand name, have a certain feature in the application.Nothing "absolutely universal" can not, in principle, no matter what the issue is neither concerned.So with adhesives.All of them can be used to solve various problems, but the specifics of their preparation and ingredients used (including their equity ratio) is determined by some "sharpness" of the final product under certain conditions.

In other words, each type of the product somewhere will show all their properties more efficiently, but somewhere - less.

Second , given the fact that the adhesive is acquired for a particular purpose, do not have to pay for the entire "set its functionality," especially because all the specific possibilities of the material, as a rule, at the same time and do not need.Such a rational approach to optimizing purchasing costs.

Selection Criteria

In principle, the indicators that will be indicated below, you should pay attention when buying any adhesive.Therefore, it is sufficient only to remind them and briefly explain some moments.

maximum time an "open" application

This is the interval during which the applied composition retains ductility, malleability, not cures.That is the time in which you can manage to produce any manipulation with glued samples (tiles and base) without the risk of damaging anything.If the experience in such work is not enough, you have to constantly something to correct, trim.

This indicator can be designated, and as a "time adjustments".In principle, the same.

«Flow out»

in quotes, because this characteristic is called differently ( "to creep resistance" and the like).On it is necessary to pay special attention to two cases.Firstly , when mounting the tiles made on a vertically oriented substrate.Secondly , if the treated surface is porous or is characterized by numerous cavities, cracks and other such defects.

suitability for use Time

This refers to the two-component compositions.Meaning - for how many hours of mixing the paste and curing polyurethane adhesive retains all its original properties (viscosity, etc.)?It depends on the amount and composition being prepared.It is especially important if the work will be accompanied by any technological break.

consumption per unit of surface

This value for almost all tile adhesives is the same, but clarified yet (if you have a choice) should be, as there are some nuances.

specific application

Here everything is quite simple: some compositions are more suitable for "warm" floors, while others - for a label on the base, subject to periodic vibration, deformationand so on.

cost

To navigate in pricing, rather, as an example mention several varieties of polyurethane adhesive for tiles:
