I'm interested in this product but curious if you can install over existing sheet vinyl. We have original sheet vinyl over 3/4 inch plywood subfloor which has some deflection. Is it advisable to put down a thicker underlayment on top first? We actually had LVT installed over the sheet vinyl with grout but the grout started to crumble immediately. So we have to start over. I�d prefer this product since it�s also non toxic. But want to make sure it�ll hold up on our existing floors. Thank you!

Marmoleum Click flooring can be installed on any clean, dry and structurally sound subfloor including vinyl or LVT as long as the floor is flat to within 3/32" in 6'. If the deflection is greater than that, a patching compound, floor leveling compound or new plywood subfloor must be used. Grout is not a structural product which is why it crumbled.
