- Applications
- Sealant for a variety of DIY applications
- Suitable for many general industrial sealing and bonding uses
- Specifically suitable for areas exposed to high humidity
- Adhesion WACKER® GS - GENERAL SANITARY exhibits excellent primerless adhesion to most non-porous siliceous materials (e.g. glass, tiles, ceramics, enamel, glazed tiles) metals (e.g. aluminum, steel, zinc or copper) or painted wood
- Application Details
- The substrate areas that will be in contact with the sealant must be clean, dry and free of all loose material such as dust, dirt, rust, oil and other contaminants. Non-porous substrates should be cleaned with a solvent and clean, lint-free, cotton cloth. Remove residual solvent before it evaporates with a fresh clean, dry cloth. For application from cartridges cut thread open, fix nozzle on top and cut to required bead size. The sealant can be applied in beads or layers. It requires moisture in order to cure.
- The curing time can take longer at lower temperatures, lower humidity or by low volume of air exchange.

Regulatory & Compliance
- Certifications & Compliance
- Chemical Inventories
- Restrictions on Use
- WACKER® GS - GENERAL SANITARY should not be used on substrates such as marble, concrete, fibrous cement and mortar, as the product releases acetic acid during curing.
- WACKER® GS - GENERAL SANITARY should not be used in contact with metals such as lead, copper, brass or zinc due to corrosion. WACKER® GS - GENERAL SANITARY may be discolored in contact with some organic elastomers, e.g. EPDM and neoprene.
- WACKER® GS - GENERAL SANITARY is not recommended for sealing of aquarium or for long term use under water. WACKER® 121 - AQUARIUM has been specifically developed for aquarium applications.
- WACKER® GS - GENERAL SANITARY should not be used on pre-stressed polyacrylate elements as it may cause environmental stress cracking.
- WACKER® GS - GENERAL SANITARY must not be used for structural glazing bonding. It is the responsibility of the user to test the compatibility of the sealant with the adjoining materials. Incompatible substances like coatings or organic plasticizers can lead to discoloration of the sealant. Cleaning agents and gaseous emissions can damage the sealant in its function or change its appearance.
