What will the fiberboard give us on the floor in the house?
Fiberboard, manufactured by hot pressing of sawmilling and woodworking waste with the addition of synthetic resins, antiseptics and other stabilizing agents, has a number of serious advantages over natural wood. The lacquered surface does not require any treatment, the dense structure keeps the screws, nails and screws well. And, finally, the most important advantage is a low price.
However, despite the fact that the structure of the fiberboard includes hydrophobisers, sheets, in order to avoid their deformation, should be protected from getting excessive amounts of moisture. In addition, they quickly wipe and lose wood in a purely visual perception.
Preparing the basis for the floorboard
Before starting the conversation about how to lay the fiberboard on the floor, we will find out what preparatory work is needed. First of all, the humidity of the decking sheets should be as close as possible to the humidity of the room, otherwise the sheets will inevitably collapse after laying.
To prevent this from happening, in an irregularly heated room the underside of each sheet of the fiberboard is wetted with warm water, the sheets are superimposed on the backs of each other and left for 24 hours. After that you can start work.
If the room is heated regularly, then simply put the sheets on the edge and leave the room for 48 hours.
The floor of the fiberboard is laid on a cement-sand screed, or on a wooden floor. If, after receiving the screed, no primer was applied to it, then this must be done now. As a primer, the bitumen dissolved in gasoline is used in a ratio of 6: 1.Before applying the primer, the base is cleaned of dirt and dust.
Cold mastic or glue is applied to the entire primed surface of the screed, the thickness of the mastic layer should be no more than 0.6 mm, and the adhesive layer - no more than 0.3 mm. The lower surface of the plates is also greased with glue 30 minutes prior to the beginning of laying.
Hot mastic is applied only to the area on which the slab is currently stacked. This is done so that the temperature of the mastic does not have time to fall below 140 degrees. Its layer can not be thicker than 1 mm, for which the mastic immediately after application is leveled with rubber combs.
The process of laying the floor from a fiberboard
And, finally, we came very close to the question of how put the fiberboard on the floor of the .All the slabs are stacked in such a way that there is a gap of 5-10 mm from the walls. Usually the first plate is laid in the corner opposite the exit. It is firmly pressed, checking the level in all directions.
The remaining slabs of this and the subsequent rows are stacked in a similar manner, with gaps in the joints not exceeding 3 mm. It is very important to adhere to the requirements of fire safety.
In those places where the plates of the fiberboard are adjacent to vertical pipelines, along the whole circumference of the pipes it is necessary to leave a gap filled with cement-sand mortar. At a tube heating temperature of up to 80 degrees Celsius this gap can not be already 10 mm, and when heated above 80 degrees the gap width increases to 50 mm.
The installation of fiberboard on the wooden floor is no different from the above method, the only difference being that there is no need for a bituminous primer, and the plate itself can be nailed to the wooden floor boards. The question of how to paint the floor of a fiberboard is reduced to applying on its surface a layer of alkyd enamel for external work, or to paint it with paints.
