Nowadays, it can be done cheaply and easily. If you are interested in both, now I tell ...
On the shelves of hardware stores now you can find many supplements that are at times improve the quality of the solution, as well as ready-mix, and all kinds of glue. But the prices for all this diversity, to put it mildly, indecent.
But there is one supplement that is added to the solution during the Soviet period. This ingredient is suitable for virtually any type of mixture.
In Soviet times, and get ready to buy cement and adhesive solution was almost unreal, and not doable task. Therefore the people came up with a method of making such a solution. This method comprises adding PVAc in cement. This mortar was used for all kinds of works: plastering, laying tiles, floor concreting, and other works.
When adding adhesive solution becomes more elastic and tenacious strong, which increased several times the quality of work.
Unfortunately, there is one "but." Not every adhesive suitable for this method. To obtain a positive effect needed MB - PVA glue. In its structure to be polymer entitled polyvinyl acetate. It is very resistant to high and low temperatures, is flexible and has high adhesion to all types of surfaces.
But then brewing the following question: how much or in what proportion should be added to the solution adhesive. It all depends on the purposes for which you knead solution.
- if you need a solution for ceramic tile laying (especially for laying on the wall), it is taken 1 part cement, 5 parts sand. In this dry mixture was added to PVA-MB glue in a ratio of 20% of the cement. If necessary, add a little water;
- dTo increase the strength of the concrete mixture and increase its ductility is added 5 - 10% adhesive on the amount of cement;
- kneaded for concreting the floor 50 kilogram cement, 100 kg of sand, 150 kg of crushed stone. Add 10 kg of glue (20% by weight of cement). Water is reduced by the amount of added adhesive;
- Repair crumbling of concrete walls used in composition ratios: 1 part cement, 3 parts sand and 0.5 parts of adhesive. Such a solution is very tightly adhered to the old coating;
- surfaces for plastering solution was kneaded in the proportions of 1 part cement, 4 - 5 parts sand. And 10 kg of this solution was added 60 - 80 ml of PVAc-MB.
In the late 90s I was a father lecturing in the bathroom tiles 10 x 10 cm. And the solution we poured it PVA glue. 2 years ago, I have decided to replace the tiles on a beautiful and big, but the dismantling of the old I have long berated those who had offered the old tiles.
With great difficulty, I still dismantle it. So I became convinced in practice the effectiveness of the addition of glue PVA-MB into the slurry.
