OS111 is a high performance, bituminous sealant and adhesive that can be applied on damp, wet or submerged substrates. Ideal for a range of external weather sealing. Contact with light-coloured plastics may cause discolouration. Always test compatibility with polystyrene before use as results can differ. Thick application and high temperatures may lead to solvent entrapment and impaired adhesion. OS111 is not over paintable.
