Elastic sealing of expansion joints, corner and joint joints in bathrooms and showers. Silicones for bathrooms and WC's in the home with natural stone cladding, on doors, windows and mounting elements in cladding on balconies, terraces and on facades. 

Product description:

ARDEX SN is a one-component, alcohol-curing silicone sealant, which can be easily injected and smoothed. Due to the high elasticity, stretching and undercutting movements are compensated by up to 25 % of the joint width. After curing, ARDEX SN is resistant to weathering, UV rays and commercially available cleaning and disinfecting agents. The joint is easy to clean. Thanks to the fungicidal finish, it prevents the formation of fungus and mould.

Substrate preparation:

ARDEX SN adheres well to glazed and unglazed tiles, enamels, glass, sanitary acrylic, polished and anodised aluminium, plastic, wood, coated kitchen worktops, solvent-free acrylic lacquers, alkyd resin lacquer and thick-coat glazed lacquer. 

With concrete, mineral plaster and stainless steel, use ARDEX Primer SP 1; with chrome and hard PVD, use ARDEX Primer SP 2 (see adhesion table).

The joint edges must be firm, load-bearing, dry and free of dust, dirt, grease, oil and paint. Old sealant residues must be completely removed. Greasy joint edges, as well as the edges of bathtubs and shower trays, must be cleaned with suitable cleaning agents.

Deeper joints should be pre-filled with a polyethylene cord with closed cavities. The bottom filling material must not be damaged during insertion. For shallower joints where no round profile fits, the bottom of the joint is covered with polyethylene tape to prevent adhesion on all three sides. Indoors, the joint width should be a minimum of 5 mm, outdoors a minimum of 10 mm.

outside, a minimum of 10 mm. Under no circumstances should bitumen, tar, oil or acrylic waterproofing filler materials be used.

Instructions for use:

Cut the tip of the cartridge above the thread, unscrew the nipple and cut crosswise according to the joint width. Insert the cartridge into the gun. Inject ARDEX SN into the joints in such a way that a bond is made between the joint flanks over the entire surface to achieve good adhesion. In the case of angled joints, inject in a triangular pattern. Before drying (approx. 7 - 10 minutes) smooth the sealant with a suitable tool.

the sealant with a suitable tool moistened with ARDEX SG smoothing agent and remove the adhesive tape. It is possible to work in sections, as the fresh ARDEX SN adheres perfectly to the hardened material, provided that the surface is free of dirt and dust.

The width of the joint must be measured in such a way that the practical expansion capacity of 25% is not exceeded by the movements of the adjoining construction elements (expansion, underlayment). 

In the case of external joint fillings, the joint width and depth must be at least 10 mm. 

ARDEX SN must be used at temperatures above + 5°C and below + 40°C.
