Polyurethane adhesive sealant
SIKA Sikaflex-11 FC Purform Universal PU Adhesive & Sealant, Brown 600 ml
One product for both bonding and sealing — indoors and out, on nearly any surface.
SIKA Sikaflex-11 FC Purform is a one-component, moisture-curing polyurethane adhesive and joint sealant in a 600 ml pack. It bonds and seals concrete, masonry, natural stone, ceramics, wood and metal both indoors and outdoors. The brown shade blends discreetly into timber and stone surfaces.
Bonds and seals in a single product
Sikaflex-11 FC Purform combines elastic bonding with joint sealing, so a single cartridge covers fitting trims, panels or filling joints. Its adhesion to most construction substrates is reliable and long-lasting.
Elastic joint that absorbs movement
The cured seam stays flexible and accommodates movement of up to ± 25 %, protecting the joint from cracking as materials expand and contract. Elastic recovery of around 85 % returns it to shape after stress.
Weather-resistant for outdoor use
The Purform technology gives the sealant lasting resistance to UV and weathering, so it holds up outdoors far longer than conventional polyurethanes. It suits terraces, façades and exterior detailing.
Easy application with no sagging
The paste is easy to gun out and does not sag in vertical joints, making work on walls and ceilings straightforward. It cures with air moisture and reaches full strength in about 3 days.
