Setup, Compatibility & Care
Preparation:
- Ensure the slate surface is completely clean and free from loose debris.
- Allow the surface to dry thoroughly for at least 72 hours in clear, dry weather before application. This is critical for the sealer to penetrate effectively.
- Protect any surrounding surfaces that should not be sealed using masking materials.
- Wear appropriate safety gear, including gloves, protective eyewear, a face mask, and clothing.
Application:
- Check that the ambient temperature is between 15°C and 23°C.
- The product must not be diluted.
- Apply using a low-pressure sprayer, roller, natural fibre brush, or sponge.
- Apply the first coat evenly.
- Remove any excess sealer from the surface within 20 to 30 minutes of application.
- Apply a second coat 45 to 60 minutes after the first coat for best results.
Compatibility:
- Suitable for natural slate surfaces (internal and external).
- Not suitable for Kandla Grey (mid and light grey) sandstone.
Important Note: Always test the product in an inconspicuous area first, as it permanently changes the colour and appearance of the stone.
Care:
- Clean sealed surfaces with mild detergents and water. Avoid abrasive cleaners.
