Substitutes cement mortar for masonry bricks: foam, polyurethane glue, lime, clay
With the construction of the house go the other buildings of brick, some are thinking about quality solution. Good one solution which does not shrink, the bevel design, but it will be pliable to uniformly apply it on the bricks.
Many believe that a mortar for masonry. But in some cases, for reasons of economy and practicality of use other solutions.
Lime for masonry
Plastic composition for masonry obtained from the lime. He is made from sand and quicklime. The two components are mixed and diluted with water. To 1 part lime take from 2-4 parts sand middle fraction. Such a solution is seldom used (it is less durable than cement), primarily for single-story buildings, installing baffles, barriers. But the solution is easy to install and quickly solidifies.
tile adhesive
After repairs are bags with tile adhesive and some are asking: Is it possible to lay the bricks on this solution? This is possible, but you need to know some of the nuances. Tile adhesive has a special feature - a strong shrinkage. Therefore make a thick solution and apply it to the tooth thickness of the toothed spatula. You can add sand to the solution.
Cement - mortar
This solution is the most popular among the builders. He quickly hardens, mixes well. This solution is perfectly penetrates into all the gaps, cracks are not formed after solidification. The solution does not slip with bricks. It is durable and has high adhesion. Before laying the bricks, you can soak in the water. Proportions solution: lime, sand, cement (0.5: 5: 1).
polyurethane adhesive
Adhesive based on modified polyurethane. There adhesive specifically for brickwork, natural stone and blocks. It is resistant to solvents, water, acids. No need to mix in the container material to obtain a solution.
Everything is ready for use. Sold in bottles. One cylinder replace 50 kg. cement mortar. Standing container from 500 rubles.
Clay
Is used in the masonry chimney. Such a solution is flexible, it does not sit during operation. This solution can be used for masonry walls, the outer (with protection from moisture) and internal walls. The thickness of the solution layer in the clutch should not be more than 5 mm.
The clay is filled into a container and diluted with water. In this form, it must stand for about 3 days. The quality of the solution is checked so. Apply the solution to a brick and pressed thereto a second brick. After 7 min. try to raise the second brick, and if he does not depart from the first, it speaks about quality solution. proportions: sand: clay (1: 1 or 2: 1).
Polyurethane foam
You can put a brick on the assembly foam? So do in case you need to make virtually zero seam. Foam afraid of sunlight, so think about protection. House on the mounting foam does not build, and partitions and internal walls is possible.
Strength such that it is impossible to destroy such a clutch. There is a foam that is not afraid UV and moisture (PPU).
