Neutral Alkoxy non-staining Silicone Sealant

abe® Stone Sealant is a one-part, neutral alkoxy-cure, non staining silicone sealant developed for weatherproof sealing where natural stone aesthetics are important. It cures to a durable flexible elastomer with good adhesion and excellent resistance to UV radiation, ageing, shrinkage, cracking and discolouration. Suitable for interior and exterior use.

Uses
  • Natural stone and granite joints
  • Stone cladding and weatherproof panel joints
  • Glass and tile sealing
  • Aluminium and ceramic panel joints
  • Interior and exterior non-structural sealing
Advantages
  • Non-staining formulation for natural stone
  • Neutral alkoxy cure with low odour and low VOC 25% flexibility
  • UV, weather and water resistant
  • Mould resistant
  • Good adhesion to most suitable building materials; no primer normally required
  • Non-corrosive to contacted metal
Colours

White, Beige, Grey, Anthracite and Black.

Packaging

280 ml cartridge.

 

Surface Preparation

Surfaces must be clean, dry and free from grease, old adhesive and other contamination. Where a cleaning agent is used, allow it to dry for approximately 1-2 minutes before sealing. Use separate clean cloths for cleaning and final wiping.

Mask adjacent areas before application for a neat finish. Test adhesion and compatibility on natural stone before full application.

Protection of Surfaces

Masking tape applied to areas adjacent to the joint will protect surrounding finishes and help produce a neat line. Remove the tape after tooling and before the sealant begins to skin.

Bonding and priming

No primer is normally required on suitable substrates. Test adhesion and compatibility on project-specific substrates, particularly natural stone and
coated surfaces.

Mixing

Mixing Ratio: 2 base to 1 activator by volume. Carry out mixing on a flat clean surface, such as a board or plate.

Set up carefully measured quantities (2 volumes base and 1 volume activator) of each component, side by side on the mixing plate. Do not mix until application site operations are ready. Use separate tools to remove each component from its container thus preventing contamination. With putty knives, paint scrapers or similar flat tools, mix the two components until a completely homogeneous material results. The larger the volume of the mix the longer should be the mixing time. If a filled material is required, add the filler only after complete mixing of the base and activator has been achieved. Remove mixed material to a clean surface and carry on mixing to ensure no unmixed material from the first mixing area is incorporated in the final product.

Application

Cut the nozzle to the required joint width and fit the cartridge into a suitable caulking gun. Apply the sealant continuously into the joint, ensuring complete contact with both joint faces. Tool immediately after application to obtain a smooth, uniform finish. Remove masking tape before the sealant begins to skin.

Application Temperature

Apply between +5 ºC to +45 ºC

Limitations
  • Do not use for structural glazing.
  • Do not use on surfaces in direct contact with food.
  • Do not apply to wet surfaces.
  • Do not apply to surfaces that bleed oil, plasticisers or solvents, including oil-immersed wood, oil-based crack fillers or sulfurised materials.
  • Do not apply where the substrate surface temperature exceeds +50 °C orwhen application temperatures are below +5 °C.
