Can level quik be poured over wood subfloor
The self leveling compounds work quite well on both wood and cement floors.
My house is a daylight basement and the upper Kitchen floor was in rough shape. The only problem I had was a hole I forgot to patch.
Some of the compound did make its way to the lower level and I did have to add some to a little over 18 inch square to make it flat.
That vinyl has been there since 2008 and I have had no problems.
Even with all the small cracks the only area I had anything come through was the hole that was 1/2" wide by about 3" long it had some sawdust in it and I forgot about it untill the wife asked me about the stuff dripping in my Man Cave.
