I am finishing my basement and am thinking about laying laminate floor. I am adding to a room which is already finished and does not have a sub floor. Can I put laminate on top of concrete with simply a vapor barrier? Is it a good idea? Will the laminate pucker under the weight of my pool table? Is there a certain thickness that would be recommended? Any help would be greatly appreciated!
Use a vapor barrier. Concrete will 'wick' moisture. Whether it will pucker or not depends on how flat the floor is.
If there is a dip or a rise where one of the legs sits it may show on the floor. It would probably be a good idea to spread the weight of the table out if you can think of a way. Just an opinion..
You may want to consider adding a strong material just under the table. Tile would work fine. That way you know it will support the pool table. One tip for moving a table around is to put casters (with wheels) under the legs. Much easier than lifting an 800 pound monster!
