Soudal Fix All Crystal is a multi-purpose elastomeric compound that functions as a sealant, adhesive, and filler in a single product. Its 100% crystal-transparent finish makes it the correct choice for glazing, glass, transparent panels, and any application where the joint or bond line must remain invisible after curing.

The compound adheres directly to most substrates without a primer — including wet or slightly damp surfaces — and can be overpainted with water-based systems once cured. It is food safe and tested to FDA regulations CFR 21 §177.2600(e), making it suitable for kitchen and bathroom environments.

Key Features

• 100% crystal-transparent finish after curing
• Primer-free adhesion on most substrates, including wet surfaces
• Paintable with water-based systems after curing
• Mildew resistant — contains fungicide XS1
• Food safe — tested to FDA CFR 21 §177.2600(e)
• Free of isocyanates, solvents, halogens, and acids
• Almost odourless
• Good resistance to (salt) water, aliphatic solvents, hydrocarbons, ketones, esters, alcohols, diluted inorganic acids and alkalis

Product Benefits

• Crystal transparency preserves the appearance of glass, acrylic, and other clear materials — no white or grey joint line
• Primer-free application reduces preparation time and the risk of compatibility issues between primer and substrate
• Mildew resistance with fungicide XS1 keeps bathroom and shower joints clean and free from mould discolouration
• Food-safe formulation makes it appropriate for use around sinks, countertops, and food preparation surfaces in kitchens
• The isocyanate-free, solvent-free formula minimises health risk during application and is safe for use in enclosed spaces
