q & a
-
What moisture mitigation system is recommended to be used with USG Durock™ Brand Self-Leveling Underlayment products?
Most moisture mitigation products will be compatible with USG Durock™ Brand Self-Leveling Underlayments. It is a good practice to check with the manufacturer of the moisture mitigation product before installing the self-leveling underlayment.

-
What are approved substrates for the USG Durock™ Brand Self-Leveling Underlayment products?
USG Durock™ Brand Performance Flooring products are primarily meant to be used over properly prepared concrete. The products can also be used with metal lath over engineer-approved, APA-Rated exterior glue plywood or oriented strand board (OSB) (i.e., APA-Rated Exterior or Exposure 1 panels) wood subfloors following the Tile Council of North America's F-185-11 specification at a minimum ½ in. depth.
-
What is the maximum RH requirement for installing USG Durock™ Brand Self-Leveling Underlayments over concrete slabs?
The maximum RH requirement is 75-80%.
-
When applying self-leveling underlayment, is shot blasting required?
We recommend shot blasting for two main reasons. First, it is very difficult to determine if there are any contaminants that may affect the bond of the underlayment to the substrate which must be removed prior to application. Secondly, shot blasting assures the best possible physical bond of the product. If you feel that you have a job that does not need to be shot blasted, please call for further discussions.
