Product formerly named: EMIX Stone Back 486
Saint-Gobain Weber Hong-Kong

weberfix stone back 486 is a two component polymer modified cementitious material for fixing fabric reinforcement mesh on sandstone back surface. It's extra polymer content is suitable for highly water absorbing substrate. It has high bond strength, high water proofing and low shrinkage to prevent sandstone from debonding. weberfix stone back 486 is ideal for installation of fabric reinforcement mesh on sandstone or highly water absorbing stone with enhanced adhesion strength to the reinforcement mesh and highly compatible to cement based materials which do not require removing mesh during wet fixing application. It provides excellent resistance to water which can prevent stains and efflorescence after wet fixing application.

30kg powder / bag
