For example, the composition may also be bitumen. The manufacturing process involves the use of cardboard, which is coated with bitumen on one side and cork on the other. Such a combination of layers allows the substrate to obtain waterproof properties.
In addition, it acquires the ability to remove excess moisture from the final coating. If a bitumen-cork substrate is used, it will not be necessary to lay a waterproofing layer. When laying, it is necessary to turn the cap to a rough overlap, securing the seams with tape.
The cork under the laminate substrate may consist of rubber. The main difference of this material from other substrates is the ability to increase sound absorption. Such a building material is much more expensive than pure cork. Therefore, in private construction it is not used so often.
When it is necessary to hide existing dents and bumps in the substrate, one should not hope that a more massive layer of the substrate will be able to do so, while in this case it will be possible to achieve greater thermal and acoustic insulation.
The cork under the thick laminate will be more even. The most suitable option is a layer of 2 mm.
Before starting work, the cork roll substrate should be kept at room temperature for 24 hours. To prevent the layers from shifting relative to each other, a cork must be laid on top of the finishing material. The floor must be prepared in advance, this can be done by applying putty on the base. If you have to work with a cement screed, it must be covered with a primer that prevents the growth of fungus.
Moisture protection will be made of polyethylene, which must be cut into strips. They need to be laid taking into account the walls with a thickness of 1.5 cm. The overlap between the canvases should be 10 cm. You can use tape to connect the edges. The substrate should be laid at a distance from the wall, the width of which is 1 cm.
The choice of material for finishing work is quite difficult, since the main load rests on the floor, and therefore a cork substrate is installed.
The cork subfloor under the linoleum is installed only after the surface has been finished. Pieces of plywood or pegs can be used as a dungeon, but must be secured with nails. After that, it was possible to start installing the lag over the entire surface. You need to place them perpendicular to the boards.
The distance between the lags should be 50 cm. The spokes are made from below, and the lags are fastened to the surface itself with studs. At the end of the installation of the lag, it is necessary to fix them to prevent discrepancies when laying the boards.
