Tile Adhesive & Grout

Mapesil AC is a solvent-free, acetic-crosslinking, mildew resistant silicone sealant suitable for sealing glass, ceramic and anodised aluminium. It can be used internally and externally for sealing expansion and movement joints on horizontal and vertical surfaces. It forms a perfectly elastic gasket between different elements in building, mechanical engineering, ship-building and automotive manufacturing, making it suitable for use in bathrooms, kitchens, swimming pools and many other construction projects.

Recommended systems

Mapesil AC is packed in cartridges of 310 ml; to use, cut the cartridge above the end of the thread and screw on the nozzle, which should be cut at 45° to produce a hole corresponding to the size of the joint. Insert the cartridge into the gun and extrude the sealant. The surface of Mapesil AC must be finished off with a damp tool, preferably moistened with soapy water, before a superficial film has formed.
