WHAT TYPE OF MORTAR DO I USE? YOU MUST USE PREMIUM POLYMER-MODIFIED THINSET MORTAR THAT MEETS ANSI A118.4 (FOR PRODUCT WARRANTIES) OR ANSI A118.15 (FOR A LIFETIME WARRANTY). PLEASE REFER TO THE PROVA WARRANTY DOCUMENTS FOR FURTHER DETAILS.

THE COMPETITION RECOMMENDS UNMODIFIED MORTAR FOR THEIR PRODUCT WHY DO YOU RECOMMEND PREMIUM MODIFIED THIN SET MORTAR? PREMIUM MODIFIED MORTAR CONTAINS LATEX WHICH PROVIDES A STRONGER BOND OVER UNMODIFED MORTAR. MODIFIED MORTAR WILL ALSO ADHERE WELL TO WOOD SUBSTRATES. WE HAVE TESTED THIS WITH TTMAC AND TCNA ALONG WITH MORTAR MANUFACTURERS AND THEY ALL RECOMMEND PREMIUM MODIFIED THIN SET MORTAR.

CAN I INSTALL TILE RIGHT AWAY? YES YOU CAN BUT IT IS IMPORTANT TO REMEMBER THAT THE BOND FROM THE TILE TO THE PROVA- MAT IS STRONGER THAN THE BOND FROM THE PROVA-MAT TO THE SUBSTRATE WITHIN THE SAME DAY. IF YOU HAVE TO REMOVE THE TILE IN THE SAME DAY, IT MIGHT PULL THE PROVA-MAT OFF THE SUBSTRATE WHICH WILL CREATE A LOSS OF BOND. SAME THING IS TRUE FOR THE PROVA PAN. YOU CANNOT WALK DIRECTLY ON THE PROVA PAN WITH THE PROVA-MAT PAN LINER IMMEDIATELY AFTER INSTALLATION. PROVA-MAT SHOULD BE ALLOWED TO DRY AT LEAST 12 HOURS BEFORE TILE IS INSTALLED TO AVOID LOOSENING BOND. NOTE: PROVA PAN SHOULD BE PROTECTED AT ALL TIMES UNTIL TILES ARE INSTALLED AND SET.
