Fixing mosaics on non-porous
Fixing mosaics on non-porous or non-absorbent substrate with paste-tile adhesive Water can leave the whole system by;
1. Being initially absorbed into substrate
2. Evaporating through the grout joint Evaporation through grouted joints is more likely to be the main function to generate adhesion bonding. Therefore, the joint width plays an important role on adhesion generating process i.e. water can evaporate more through wide joint than through narrow joint. Anyway, paste adhesive should be left until being completely dry before grouting to ensure the optimum adhesion.
