SikaBond SBR – styrene butadiene-based waterproof bonding agent, primer and mortar admixture

SikaBond® SBR is a styrene-butadiene co-polymer, which has numerous uses as an admixture, primer, bonding agent and sealer for use in areas subject to humidity, dampness and water contact. Improves water resistance of cement mixtures by forming a reinforcing polymer that increases long term durability and flexibility of the mix on renderings and floor screeds. An admixture for cement and concrete applications, including repair and renovation, surfacing of floors and bonding generally. It contains anti-foam to control the density of cementitious mixes.

Key benefits

Excellent adhesion to steel and concrete
Adheres well to brick, tiles, glass, asphalt, wood, expanded polystyrene and most building materials
Mixes may be applied in much thinner sections
Excellent resistance to water and water vapour
A high level of resistance to salt permeation
Increased toughness and flexibility
Reduced surface dusting of concrete
Prevents bleeding
Enhanced corrosion protection
Resistant to many chemicals and to mineral oils
Reduced water: cement ratio for equivalent workability
Improved frost and abrasion resistance
Freeze thaw stable passing 5 cycles at -15 °C to +20 °C

Typical applications

Component to improve concrete repair
Component to improve external rendering
Waterproofing and tanking mortar preparation
For corrosion protection of steel
Silage pit lining and protection
Admixture for mortar, screeds and renders
Bonding agent for screeds and renders
Primer and sealer in tiling applications
Recommended for exterior use, unlike most PVA bonding aids
