To ensure a smooth installation, it is important to prepare the surface onto which you’ll be laying your floor.
The most important thing is to have a dry, even and clean subfloor. If the floor is uneven (tile joints, parquet bevels or any type of cracks), think about using a levelling compound. Remember, vinyl is a soft flooring and any bumps underneath will show.
The floor should be stable before applying a self-levelling compound. With concrete floors, this is hardly an issue, but with wooden subfloors, the task may be almost impossible to handle. If a wooden subfloor moves when you step on it, a self-level compound might not be the best decision: it will break. Furthermore, the floor needs to be cleaned from dust and dirt before applying a self-levelling compound.
