Laying a massive board on a screed: all the pitfalls
A solid board floor is formed at the very end of the repair, so that the material does not suffer due to construction and repair manipulations. The most common option is to use a screed – such a coating becomes especially durable and aesthetic.
Basic requirements for a screed
In order for a new floor made of solid planks to please the owners for as long as possible, it is necessary to carefully prepare the foundation – 80% of the success rate depends on its usefulness. It is necessary to achieve the following characteristics:
- The evenness of the screed – the density of the fit of all the installed slats of the array depends on it. For every 2 linear meters of the base, only 2 mm drops are allowed. To check how smooth the plane is, the craftsmen use a control ruler (2 m).
- Dryness. According to generally accepted European standards, the residual moisture index should not exceed 2 CM-%. If this characteristic is overestimated, there is a high probability of deformation, swelling of the slats.
- Durability. There are also quite strict profile requirements, the specific figures depend on the types of screed and board used. If the strength is insufficient, it is fraught with peeling of the base substance, the appearance of voids and loud squeaks.
When the base is completely ready, you can tear off the packaging from the packs of boards – they should lie down for a while without wrapping in order to fully acclimatize. Professional laying of a solid board on a screed can be carried out with or without a plywood interlayer.
The subtleties of using plywood
Protection from moisture is provided by polyurethane compounds, sometimes foamed polyethylene is used – an effective waterproofing barrier. Only waterproof plywood is used, its thickness should exceed 12 mm. If communications are not laid in the screed, dowels and screws are used to fix the plywood, if there are engineering elements in the thickness, resistant adhesives are used.
Plywood must be primed, and glue is applied to the dried layer. The first board is fixed so that the spike looks at the wall, not forgetting the gap, the rows of boards are attracted by self-tapping screws. If the array is supposed to dock with a ceramic-finished wall, the role of a deformation gap is assigned to a cork expansion tape, which will take on the entire load. A simple deformation step must be plastered, and at the very end it is covered with a baseboard. It is recommended to use only two-component adhesives.
The method of laying directly on the screed
If the apartment is located on the second floor and above, you can do without plywood and logs, the base should be perfectly smooth and durable. Elastic and simple polyurethane, epoxy-polyurethane two-component adhesives are usually used here. The surface is pre-primed with an epoxy compound, which increases the strength, vapor barrier and adhesion of the substrate. The installation can be started either from the middle or from the wall. It is necessary to observe the gaps that compensate for the seasonal deformation of the wood.
