Do you need a grid for plastering the plinth? (the process of working with tricks from the master)
There are many methods for finishing the base and protecting it from moisture. A more popular way is plaster. Do I need to reinforce the base before this or not? Is it better to use good glue instead of mesh? We will answer all questions and give advice from the master.
The basement is the foundation of the house. This is the protruding part of the foundation. Finishing performs several functions at once: it makes the structure attractive, eliminates defects, protects against the destructive effects of the external environment (moisture).
If the base is not strong, loose, the surface damp, gets wet, crumbles, then in this case the mesh is simply necessary. Take a brick plinth for example.
If the surface layer of the brick began to peel off, crumble, and if you just apply a solution without a grid, then it will fall off along with the surface layer of the brick, even if you use a concrete contact (it will eventually exfoliates).
Plastering the base on the grid, tips
1. We take a hard steel brush. We clean the base manually with a brush or using a grinder and a special nozzle (brush-cup). Do not forget to wear safety glasses, gloves. We clean the seams and the base itself (brick).
2. Then you need to properly prepare the solution. It is better to do this with a construction mixer. Polymer plasters are expensive, gypsum mixtures are not very durable and not moisture resistant. Therefore, cement plaster is ideal for the basement. There are ready-made mixtures and special additives that increase strength.
3. Which mesh to use? The base / plinth reinforcement can be woven (PVA) expanded metal. A galvanized mesh is best suited (cells 50x25, wire cross-section 1.6 mm.). Regular steel mesh is not suitable. It will rust on a thin layer and flush out the mixture.
4. Cut the mesh to size. The mesh is fastened to the plinth using dowel-nails with washers. Holes are drilled at an angle, and then dowel-nails are hammered in so that the mesh stretches well. She shouldn't hang out.
Fasteners are made approximately every 0.6 m in a checkerboard pattern. The mesh can be cut from above with a grinder if it extends beyond the base.
5. Further application of the solution. On a galvanized mesh, even 5 mm is enough.
