Yes, it is highly recommended to remove old flooring before installing new flooring. Here are some reasons why you should take the extra step and remove the old floor:
Prevents additional height: Installing new flooring on top of old could add additional height to your floor which may cause tripping hazards.
Better adhesion: Removing the old floor allows the new flooring better adhesion which results in a longer lifespan.
Avoids chemical reactions: As mentioned earlier, leaving remnants of old glue on your subfloor can cause adverse chemical reactions with the new vinyl.
By taking the time to remove the old flooring, you are setting yourself up for a better, longer-lasting, and safer finish. It may require extra effort, but it is well worth it in the end. Always follow the manufacturer’s instructions on how to prepare for the new floor for best results!
