What type of subfloor is suitable for vinyl plank installation?

Feb 23,20241
Vinyl plank flooring is versatile and can be installed over a variety of subfloor types, but it's important to ensure that the subfloor is smooth, clean, and properly prepared. 
Here are common subfloor types suitable for vinyl plank installation:
Plywood Subfloor:
Vinyl plank flooring can be installed over plywood subfloors. The plywood should be of sufficient thickness and free of major imperfections. A smooth and level plywood surface provides a good foundation for the vinyl planks.
OSB (Oriented Strand Board) Subfloor:
Oriented Strand Board is another acceptable subfloor material for vinyl plank installation. Like plywood, it should be smooth and level.
Concrete Subfloor:
Vinyl plank flooring can be installed directly over a concrete subfloor, which is common in basements and on ground-level floors. The concrete should be clean, dry, and level. Moisture testing may be necessary, especially in basements.
Existing Vinyl or Tile Flooring:
In some cases, vinyl plank flooring can be installed over existing vinyl or tile flooring. The existing flooring should be in good condition, without major imperfections or issues.
Laminate Subfloor:
If you have a laminate subfloor, you may be able to install vinyl plank flooring over it. It's important to check with the flooring manufacturer for compatibility and installation guidelines.
Radiant Heating Systems:
Vinyl plank flooring is often suitable for installation over radiant heating systems. However, it's crucial to follow the manufacturer's recommendations regarding temperature limits and installation procedures.
Cement Backer Board:
In areas with potential moisture concerns, such as bathrooms, installing cement backer board over the subfloor before laying vinyl planks can provide additional moisture resistance.
It's essential to note that regardless of the subfloor type, it should be level, clean, and free from debris. Any irregularities or imperfections in the subfloor can affect the installation and appearance of the vinyl plank flooring.
