I'm installing 3/4 oakflooring and I have 5/8 plywood with 5/8 particle board over the top. It's been down over 20 years with carpet over the top. When i pulled the carpet up the particle board looks like new. The nails have not popped and seem to hold good in the particle board. I really don't want to remove the particle board. Do you think it will work alright over the particle board. I not worried about warranty since i purchased the flooring from the amish and they thought it would work. Help me, anybody!
