- Applications
- Specially developed for sealing of natural substrates such as marble, granite, sandstone and quartzite
- Sealing joints for interior and exterior facades e.g. for sanitary applications where natural stone is the substrate
- Adhesion WACKER® 460 - NATURAL STONE 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); impregnated, varnished or painted wood; and some plastics.
- Application Details
Processing
- 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.
