Before laying flooring, it is important to study the technical parameters of the screed for laying laminate and parquet boards - if you ensure that all requirements are followed, the floors will delight in their quality. It is unlikely that anyone wants there to be height differences on the surface, so that the planks begin to creak over time or the gaps between them are critically large. All of this can be avoided by ensuring the correct floor screed.
General requirements for screed for laying laminate and parquet
The standard technical parameters of the screed for laying laminate and parquet boards are as follows:
• the floor surface must be leveled if the slope is more than 4 mm for every 2 m of the floor, or if the height differences for every 2 are more than 2 mm;
• if the choice fell on a cement-sand screed, high quality should be expected from it only if it is completely dry. This takes about 10 days at standard humidity and room temperature;
• there are ordinary self-leveling screeds with a drying time of up to 5 days and quick-drying, hardening in just a few hours;
• any kind of screed for laminate and parquet boards must be tested for strength. It is enough to walk along it: on a high-quality screed, the sand does not stretch behind the legs;
• cracks on the screed are unacceptable;
• garbage, dust, grains are also inadmissible.
Types of screeds for laying laminate and parquet
Most often, a cement-sand screed and a self-leveling mixture are used for this purpose. In the first case, it is possible to obtain an almost flat surface, which it is enough to cover once with a layer of soil and, in case of revealing strong drops, fill it with a self-leveling mixture locally, and then grind it.
Self-leveling screed does not need additional processing. Its advantage is quite easy application and the ability to process (level) certain areas of the floor.
If a laminate or parquet board is laid on a concrete base, such a floor must be leveled. If it is almost even, with minor flaws, it is enough to use a self-leveling mixture. With strong drops, this leveling method will cost a pretty penny, so it is better to use a cement-sand mixture. It is also the best option for leveling floors made of reinforced concrete slabs - they are always very uneven, and the differences can reach 100 mm.
These are the technical parameters of the screed for laying laminate and parquet boards that are useful for people to know before ordering a floor leveling service. This knowledge will help to control the quality of the result and avoid problems in the future.
