With the introduction of Arbokol AG2 Pouring Grade, Adshead Ratcliffe offers a two-part polysulphide sealant which overcomes problems posed by larger structural floor joints. It promises excellent adhesion, making it suitable for concrete, masonry, metal and many other common building substrates. Being a two-part polysulphide ? which cures to forma flexible rubber seal when the two components are mixed together ? it is suitable for sealing of structural floor joints which are subject to movement in expansion or compression. It resists petrol and diesel, and comes in grey or black.
