SikaBond SBR+

This SikaBond Waterproof Bonding Agent SBR can be used in multiple applications, as an admixture, bonding agent or primer / sealer. It has the advantage over PVA bonding aids, because it is not adversely affected in wet conditions and can therefore be recommended for exterior use. This product contains anti-foam to control the density of cementitious mixes.
