Arc Tilers Primer is a styrene butadiene co-polymer emulsion for use as a primer; bonding agent and sealer formulated to improve, adhesion strength and long-term durability of the bond between the adhesive and any surface substrate.

• Can be used as a water-proof bonding agent when mixed as a slurry with neat cement and can readily be incorporated into mixes of sand cement screeds, plasters and renders, giving a water reducing and plasticising effectas well as improving wet-tack and adhesion of the render to the existing base masonry
• It is an excellent primer for porous surfaces such as gypsum plaster, old / worn concrete; sand cement screeds and render by reducing porosity, surface dusting and improving initial tack so that subsequently applied adhesives, renders or screeds can achieve a secure and lasting key with the base substrate.
