CS 25 Sanitary silicone is used for sealing joints in sanitary areas as well as expansion joints in ceramic coverings indoors, outdoors and in permanently wet areas. Adheres to plastics, enamelled and glazed surfaces. Not suitable for use on surfaces in contact with food, drinking water tanks and aquaria.

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.
