Q: What kind of underfelt should I use under my area rug on my bamboo floor. I was told not to use rubber.
Is this true?
A: I would use a mesh type underpad. Some rubber pads will disintegrate and contaminate the finish.
Padding for an area rug
Q imported from our old site, Face Lift Floors: Are there any precautions which should be used when laying a large area rug over a hardwood floor? Should padding be used?
A: I would definitely use padding because the carpet will surely move on the floor and the backing will act as an abrasive on the finish. I would use a mesh type of pad which will grip the carpet and still allow the floor to breathe.
