Preparatory work before pouring self-leveling floor

Preparatory work before pouring self-leveling floor – Leveling the floor with their hands using a self-leveling floor , not an easy task , but it is doable , because at home volumes pouring self-leveling floor is not so great.

First, please be an indispensable tool . Need: construction mixer , a large water tank (same tub or barrel ) , container for mixing and pouring the solution ( fits round plastic bowl for 20 liters ) , mop or needle roller on a long handle , as well as ” cat ” , which I talk about later ) .

Then the supply of essential materials : wooden slats 1 cm thick on the entire perimeter of the square fills, dry mixture in bags .

Calculate the approximate volume of the dry mixture can be considering the volume to be filled . For convenience, you can use the most accurate level gauge in a clear plastic hose and a ruler. Determine the height differences across the room and, based on them, it will be possible to calculate the volume being filled by applying basic formula for the volume .

We should begin as always with the preparation of the surface fill. The substrate must be free of debris, dense. Maximum dismantle the old floor covering. Initial processing of loose surfaces can be supplemented impregnated deeply penetrating primer. Screed is poured from a height of 3 cm or more. If you want to raise the floor level to a high altitude , you can fill in a few layers of the inlet floor , but I would recommend pre- pour cement screed rough sex, which should be about 3-5 cm less than the required height . The remaining 3-5 cm cover the filling floor. This way you will save your money as well as self-leveling floor is much more expensive cement screed.

When you fill screed for floor screed or concrete base , carefully backfill all the gaps in order to avoid leaks, then prime with the surface on which will be poured screed . Primer must dry before pouring self-leveling floor for 24 hours.

If you fill screed on the boards or loose surface all the cracks over the entire surface of the upper floor . The entire floor must be sealed so as to exclude any leakage of the solution.

Along the perimeter tamp wooden slats , they will be installed temporarily to allow later expansion gap between the filling floors and walls. If the room is on the floor there are places that you want to crawl (collector heating , drainage and so on ) , they also limit the wooden slats or , if this is not possible with other materials – foam , polyurethane foam , and the like .

Now that all the preparatory work on the floor filling made ​​, proceed to fill the immediate self-leveling floor .
