I had a leak/flood recently, had to get rid of old linoleum and carpet. Now the concrete floor is exposed. Fans dried out the place for 4-6 days. I want to put engineered wood flooring on top of the concrete slab. Due to the moisture from flood, do you recommend just a moisture barrier sealer, or sheetings before putting on the flooring? How about plywood first? The place was soaked overnight. Moisture crept up walls 8 inches. I heard it's good to put plywood planks first, or a vapour barrier to seal concrete first. For the sealer, the flooring guy wants $1000, isn't that excessive?
My house is 20 years old. Do I need a moisture barrier or vapor barrier to be used before installing wood flooring? I've heard a million different opinions. I want to use Boston's Best, I've been assured that is all I need.
