Conducting repair work, owners of housing increasingly prefer the device for cement screeds as an finishing coating.
Such a type of gender guarantees strength, durability, and recent developments make it possible to apply designer art.
The production technology of bulk floors does not cause questions when filling them onto the slab overlap. But the bulk floor on a wooden base - this problem seems intractable. Consider how to properly prepare the wooden foundation under the fill and what to pay attention to prevent errors.
Required basics properties
If the floor boards are packed to lags, which are fixed on a concrete base, then it is better to dismantle everything to the draft screed.
This will significantly simplify the process of filling the floor and guaranteed to increase its service life.
The boardwalk flooring as a base for bulk sex must have certain characteristics:
- The coating should be tough. Do not allow playing or poorly fixed elements.
- When the physical pressure of the floor board should not be fed.
- The floor must have a minimum run in the height level.
- The tree should not have any damage. Boards with signs of rotting or large cracks should be replaced.
It is important to check for the presence of defects not only the material of the finish coating, but also lagows. When the boards is deflection, an additional base timing should be paved.
If the waterproofing is absent, remove the old coating and bed protective film
Be sure to make sure that the floor isolation state. If the material was proud or did not fit it, it is necessary to do this. To do this, you will have to dismantle everything to the rough floor, the film is to be able to restore the boarding coating. It must be done because the tree is a living material and reacts to moisture.
The boards that the screed will be poured should not be subjected to any changes in order not to destroy the cement layer.

If the wooden basis meets all of the above requirements, you can proceed to prepare for the fill of the floor.
Preparatory stage
Under the bulk floor on a wooden base, it is necessary to remove the maximum smooth surface. Preparation is perhaps the most important stage.
From how well the base tree is treated, the quality and service life of the future bulk sex depends.
Collect the old coating by removing the layer of paint and varnish
Priority of work in the preparation process:
- It should dismantle all the plinths with the elements of fasteners and mark small cracks or holes in the boards.
- Floor cycling is performed, with the layer of removal may be more than normal. It is necessary to get rid of paint, varnish or other coating. At the same time, get rid of small dents and shallow chips.
- There is a sealing of unquided gaps with bars or putty.
- The surface is polished to give light roughness and getting rid of excess putty.
- The floor is brushed. Cleaning fine garbage and dust. Surface degreases.
After the above events, the floor must be projected. What makes it necessary for at least 2 times. It is done in order to improve the clutch of the screed solution with a wooden material.
Pick the correct primer with quartz sand. Such processing will give the floor additional roughness and increase the degree of adhesion.
When mixing a cement-acrylic solution, be careful with the addition of water, the surplus will cause cracking
Specialist advice:
- Before making a bulk floor on a wooden floor, check the level of humidity in the room and the air temperature. Observe the recommendations prescribed by the manufacturer on the packaging.
- Before the fill, curse the damping tape the entire perimeter of the floor, it will help to avoid additional risks of the breakdown of the screed.
- According to the technology, the top layer is performed by the level. Check the manufacturer data, is allowed to use this particular mixture on a wooden base.
- If a cement-acrylic solution is used in the work, then mixing it, try to avoid re-securing water. Big water during drying will give a crack tie. About how they make bulk floors on plywood base. See this video:
The fill height is no more than 5 mm, to control the thickness and flatness of the layer, install lighthouses on the area of the room.
Types of blends for filling the floor, their advantages and disadvantages:

| Mixture | Dignity | disadvantages |
|---|---|---|
| Polyurethan | Resistant to UV rays Ability to device 3D floors | Low resistance to mechanical damage |
| Epoxy | Almost zero susceptibility to chemical and physical influences | Long cycle ready High price |
| Methyl methacrylate | Fast Readiness for Operation High strength | Toxic to frozen |
| Cement-acrylic | Sustainable mechanical loads | Labor time crops |
The fill process
Having arrange the bulk floor along a wooden base, mix the solution strictly in the proportions indicated on the package. In the absence of experience, mix small batches so that the solution does not thicken. Start the fill with the wall opposite to the door, from a long corner. About how they make bulk floors on a wooden basis, see this video:
As a rule, work is held in a specific sequence:
- Mixed solution. The ideal density of the solution resembles a thick sour cream;
- distribute the mixture on the surface with the help of a rochel or a spatula, achieving the necessary thickness;
- Remove the beams;
- Remove the air, walking along the surface of the layer with a needle roller.
Buying a roller, take into account the thickness of the flooded layer: the size of the needles should be greater than 2 mm thick. Otherwise, the base of the roller will touch the fill layer and create on the surface of irregularities.
Give a flooded layer to dry for 2 days
The flooded layer should dry for 2 days at constant temperature and humidity. In the first time, do not allow water to enter the floor surface.
Self-leveling floor for wooden bases can be used not only for a dumping basis. Self-confined mixtures can be poured on Phaneur. At the same time, it is better to choose polymer mixtures for the fill.
It is necessary to approach work with cement solutions. When working with aqueous solutions, it is better to describe the water waterproofing film. If necessary, on top of it put the reinforcing grid.
