Wish Id seen sooner as I need for today so will have to pay the £28 elsewhere But hopefully good deal for anyone not needing it same day
FLEXIBLE Suitable for use as a flexibiliser for cementitious-based tile adhesives when used on wooden and asphalt flooring.
WATER RESISTANT Unlike PVA, SikaBond SBR is not negatively affected by wet conditions and is suitable for exterior use.
EXCELLENT WORKABILITY Reduces water to cement ratio, allowing this general purpose admixture to be applied in thinner, more workable sections.
