About Larsen Weld-Crete

Informations about our construction products and our philosophy

Larsen Weld-Crete bonding agents have been specified by major architects, engineers and construction companies throughout the world since 1952. The company has invented and patented its high strength bonding agent which incorporates polyvinyl acetate homopolymer. The product is very easy to use by painting on 1 coat direct from pail/tub and it waits for placement up to 10 days.

Use larsen bonding agents wherever you require a high performance bonding of cementitious material direct to structural surfaces (brick, block, tile, marble, metal, glass, timber board).
