I have noticed my concrete slab floor aborbs moisture. I need to know what kind of sealant should I brush down on my slab flooring to keep the moisture from accessing my future laminate.
I have already purchased my laminate from a company going out of business. I also purchased some blue foam with it. I find out the foam I bought is the cheapest you can get.
This means it will echo when the laminate is walked on.
What kind of underlay pad is the best. and........since I already have this cheap foam can i put it down on the bottom and then put better underlayment on top? Would this help to keep the floor more cushioned, less hard and lessen the echo and provide more better protection to my laminate?
