CS 42 Marble Joint Silicone seals joints between building elements made of brickwork, concrete and tile coverings and is used for expansion joints in natural stone and marble coverings made of granite, limestone, quartzite, travertine, shell marl, sandstone, Solnhofen tiles and Carrara marble. Adheres without priming coat to polyester, porcelain, wood and tiles. Not suitable for use on surfaces in contact with food and in drinking water tanks.

Step by step

Joint flanks must be dry, sound, clean and free from substances which may impair adhesion (e.g. oil, grease, old sealant). Screw the nozzle on and cut it off at an angle to match the joint width and fill the sealant into the joint.

Smoothen the sealnt joint within 5 minutes using a suitable tool (e.g. spreader) and water with a little dishwashing liquid or soap added. Always avoid adhesion to three flanks. Observe joint widths of at least 5 mm indoors and of at least 10 mm outdoors. Fill expansion joints with a strip of closed-cell foam beading.
