How thick a layer of self-leveling floor compound can you pour on a subfloor to level it? -Jack
Hi Jack,
It depend on the particular floor leveling product you’re using, but most manufacturers recommend that you apply no more than 1/8” thick coat of self-leveling or floor patch compound at a time. However, you can apply several thin layers of the compound, if you allow each to set the recommended time, to increase the thickness gradually up to 1/2” thick.
Be sure to read the application instructions for your particular floor compound to find out more.
Good luck with your project,
