The thickness of the screed

Many are confident that the thickness of the screed must be at least 4 cm. But it is available for sale, new building materials that help to make a screed of 10 mm.! In this case, you can save on materials and speed up repairs.

But it is necessary to observe at least 4 cm in thickness with a floating screed. Floating screed is made when the floor insulation. Screed is not mounted on the floor slab, and the separation layer. It is advisable to add to the screed reinforcement.

Level

The mistake is to take the floor level of the apartment entrance. Consider the fact that the blister coupler is mounted the finishing material (tile, laminate, carpet, plywood and the like. D.). Rough level of the apartment must be below the entrance floor.
