If anyone had watched last weeks show where they installed snaplock cork flooring, DO NOT do like they did on the show when installing it. You do not need to smack it into place with a hammer.
The correct way to install it is you first assemble the entire row, then place it into the groove of the existing row and snap the entire row into place. Smacking it with a hammer and block is not recommended by the manufacturer of these products and they can void the warranty if they detect that the boards were hammered in. Not only can it damage the edges of the top finish, it can damage the snaplock on the tongues. I talked to a rep from the company that makes snaplock cork flooring and asked about the way they assembled the floor and he gave me the run down on it.
