Can OSB boards be laid on the floor? Why OSB is the best flooring material (OSB installation)
Many people ask: "Is it possible to lay OSB slabs on the floor?" How does the material behave over the years and what is the correct technology and advantage over other materials? Given the characteristics of the RSD, conclusions can be drawn on these issues.
In the manufacture of plates, chips are used. They are arranged differently in layers to provide higher strength than in plywood or chipboard. A larger percentage in the composition is a tree (pine or spruce). Therefore, the material is harmless. There is formaldehyde in the composition, but only a small fraction, which is not dangerous.
From this material, floors are made along logs or along a concrete screed. Minus one, like all wooden products - OSB is afraid of water. Therefore, a polymer or cement-polymer waterproofing is needed. By the way, tiles adhere perfectly to a cement base and cost less than a polymer one. If laminated OSB is used, then additional waterproofing is not needed.
The material can be left uncovered with a floor covering. From above you can paint or varnish the surface of the plates.
OSB is divided into 4 types:
Osb1 - the cheapest option, but not moisture resistant and is used in rooms with low humidity.
Osb2 - often used in the manufacture of furniture. Increased moisture resistance.
Osb3 - plates are used for external and internal work. Can be used for flooring.
Osb4 - the most durable material, high class with increased moisture resistance and strength. They are used for the construction of outbuildings and frame houses.
If laying will be done on a concrete base, then 1 cm thick OSB will do. You can lay the slabs in 2 tiers in case of obvious defects in the base. In this case, use a plate thickness of 6-8 mm. If by lags, then you need to choose 2 cm. (thickness of smallpox).
OSB on the floor along the logs is similar to the installation of plywood flooring.
OSB to sex of concrete glued with assembly glue (universal). But before work, you need to prime the base and dry well. Can be fixed with dowels. Plates are fastened with offset seams. It is important to leave a gap around the entire perimeter. Also, a gap of 2mm is made between the plates, and then the slots are closed. silicone sealant.
But if a parquet board, linoleum or laminate lies on the smallpox, then you do not need to seal the joints with a sealant.
OSB is one of the best materials for the floor, which allows you to level the surface without dirt and dust. Use osb 3. Any floor covering will fit well on such a surface: tiles, laminate, porcelain stoneware, etc.
