SurfaMix C is an admixture for cementitious mortars that enhances adhesion and bonding on application surfaces. Furthermore, it improves elasticity and reduces cracking, shrinkage and the formation of water absorbing capillaries. 

Plasters, renders, exterior and interior masonry coatings, cementitious mortar/grout, patch, repair and reproling mortars, adhesive materials for tiles/stone, floor screeds/overlays

"Individual nanoparticles exhibiting water repelling properties coat the pores of the mix and reduce water absorption. This process results in renders, plasters or cement surfaces that are very resilient to weathering." (language removed from website)
