USG Durock X2 Primer Sealer

USG Corporation and XL Brands have partnered to introduce USG Durock X2 Primer-Sealer. What’s new about this particular primer sealer is that it’s the first of its kind to give users a 10-year limited system warranty. Made to be used directly over USG Levelrock or USG Durock gypsum underlayments, USG Durock X2 primer sealer offers the 10-year warranty provided it’s used in with an XL Brands adhesive.
