Chipboard on the floor under linoleum - features of surface preparation
The availability and low cost of chipboard makes it possible to consider them as a material for arranging sub-floors. The very process of installing chipboard on the floor under linoleum is not a big problem, if you do not save on materials and follow the main rules for waterproofing the base.
You only need to decide for yourself, in which the use of chipboard in a residential area is justified.
Technological laying process of rolled linoleum cloth on the floor in rough processing from chipboard has already been worked out many times and is constantly used in order to to equip floor coverings in utility rooms with earth and concrete floors. On the construction market there are many special mastics and glue compositions that allow you to stick linoleum on chipboard with a quality guarantee of 10 years.
It is only necessary to decide whether it makes sense to use chipboard as a base for roll material:
Please note that after 1/2 year of storage in weather conditions, the chipboard will chip off into pieces even under light load.
Such material cannot be used as a substrate for linoleum.
For the installation of chipboard under a layer of linoleum on a concrete floor, it is required to use only brand new slabs, and in no case used. The optimum thickness is 1 cm. The material should be stored indoors, only in a horizontal position, ideally in a pack. All the difficulties that are listed above can be easily eliminated by observing the laying technology, and given the significantly lower cost for plywood and OSB, the installation of linoleum on subfloors made of chipboard building material can be a completely justified solution.
Before starting the assembly process of subfloors, it is necessary to bring slabs into the room and leave them for at least a day so that the material gains the required degree of moisture. If you lay slabs of shavings just taken from the garage or shed under the linoleum, as the floor dries, gaps will form between the sheet joints.
How to process the chipboard before laying
Regardless of the floor on which you plan to lay the slabs, board or concrete, pressed particle boards must be treated with a protective compound. When fastening the back side to the concrete surface, they are treated with linseed oil or varnish bitumen composition. A certain type of treatment is chosen depending on the method of fixing on a cement-sand screed.
The most reliable option is processing with hot drying oil. Heating the mass easily falls into the thickness of the pressed shavings and dries quickly in 1-2 days. The coating must dry before the chipboard is laid on the floor. The face of the chipboard should be easy to process and therefore can be coated with acrylic or polyester varnish.
Good advice! For laying the material, it is required to choose more of the side of the chipboard, after applying the varnish, the surface should dry in a horizontal position so that there is no formation of smudges and waves.
Features of leveling the floor Chipboard
Chipboard under linoleum is needed on a wooden floor for leveling. In order for the coating for rolled material to be horizontal and perfectly even, it is required to nail the chipboard onto the floor with nails, at least 15 pieces per sheet. The chipboard must be laid on the floor in advance and the coatings are smoothed by means of wooden linings. On wooden floors, chipboard is fixed with an "oblique" fight, since otherwise the nails may come out of the substrate. In no case should you hammer nails into the chipboard itself, and it is also required to drill a hole in advance so that the tip does not knock out a piece of chips from the back.
the pads are screwed onto the floorboards with self-tapping screws. All that remains is to apply polyurethane foam to the floor, lay chipboard and nail it onto the floorboards. When laying chipboard on concrete floors, self-tapping screws are used for sheet alignment, which are screwed into the body of the slab. After leveling, the chipboard backing is glued onto polyurethane foam or mastic.
Preparatory stage for gluing linoleum
After the chipboards have been laid, it is required to clean and glue the seams.
The preparatory stage of the floor for laying the floor covering in the following order:
- It is required to apply a varnish composition to the rough chipboard and joints, dry to the state of maximum hardening. The surface must be very hard so that it can be prepared for linoleum flooring.
- The assembled rough-type floor must be sanded with an emery cloth so that the surface is even, without depressions and holes, as well as pricks and protruding chips.
Moreover, the joint around the perimeter must be caulked with a sealant or wax mastic. This is required in order to compensate for the thermal expansion of the material.
For the base made of wood, sheets with a thickness of 1 to 1.5 cm can be used, thicker panels with a thickness can be laid on the concrete floor up to 2 cm. If it is noticeable that the floor is complex, and there is a possibility that you will not be able to level the surface under PVC linoleum, then it is better to buy materials with a margin of thickness. After fixing the sheets on the self-leveling floor or floorboards, protruding edges often remain at the joints, and the height difference can reach up to several mm. In this case, you can grind the joints with an electric tape machine, and the resulting dust with glue can be sealed in the cracks, and only after that the surface can be primed.
Chipboard is glued much worse than OSB or fiberboard.
The structure of the material is such that a lot of glue mastic will simply be absorbed, and therefore, without priming, there is simply no point in applying a linoleum adhesive composition to the chipboard surface. By the way, the glue must be liquid enough.
Immediately you need to specify adhesives that are definitely not suitable for laying linoleum based on shavings:
Only butyl-polyurethane, isoprene and polyurethane compositions can be used for gluing linoleum. The best are German and Italian brands. Such an adhesive composition not only holds the coating on the chipboard base, the polyurethane seam also contributes to high-quality fixation and preservation of the chip mass.
So, first you need to cut out the panels.
Linoleum needs to be cut into separate sections based on an allowance for wall surfaces of at least 2.5 cm. If imported material is placed on the slab, that is, it can be glued without any exposure. Traditionally, domestic brands are spread on the floor for 2-3 days so that air bubbles do not appear. The canvas needs to be rolled up and laid along the wall, opposite the entrance to the room.
After that, it is required to apply and thoroughly grind it on the surface of the base of the slab, and at the same time roll out the linoleum. After all the pieces of the covering have been laid out, it is required to roll the canvas onto the floor using a heavy roller or a plastic wallpaper spatula. After the adhesive has set, cut the joint line and the edge of the coating around the entire perimeter of the room.
Applying chipboard on a concrete floor under linoleum is a great idea to level the surface. The phenol and resins in the composition are blocked by the adhesive and PVC base of the floor covering.
The material is very cheap, and therefore sheets of pressed shavings are used mostly for large rooms with heating and excellent ventilation. If glued correctly, then the material will serve no worse than OSB.
