How to prepare for laying a parquet board
The state of the base is very important when laying. It may contain bumps, but their value cannot exceed two millimeters per linear meter.
During laying on a solid surface, it is worth providing a substrate under it, it will help compensate for irregularities and make walking around the room pleasant. The soft surface may not require a substrate, linoleum itself will act as it. Carpet coatings cannot be used as a substrate when laying a parquet board, this should be remembered. However, the cork substrate is quite suitable.
