Q: About 7 years ago we put down carbonized vertical bamboo flooring with a glossy finish, which we now can’t find. We want to put it down in 2 bedrooms, but can’t find any with the gloss finish, just matte. Can we buy the matte finish product and cover it with glossy polyurethane?
Can we use a spray product, or would we need to brush on?
A: You will have to completely buff the old coating with a fine to medium abrasive so the finish will bond. I would recommend a really good quality polyurethane such as Poloplaz Primero. It rolls on really well.
