- Touch dry 2 - 3 hours
- Fully waterproof 24 hours
- Suitable for Sandstone, Limestone, Terracotta, Travertine, Slate and Granite

PREPARATION: Pre treat surface with appropriate cleaning product. If required, fully clean off using a pressure washer and leave to dry thoroughly for at least 3 days. In order to apply sandstone or natural stone sealer, the area must be clean, dry and free from contamination.
Always test product on-site, in an inconspicuous area, to ensure you fully are satisfied with the final appearance/ colour of the surface.
**If applied to a surface where a "sweep-in" pointing compound has been used within the last 6 months, the natural stone must be fully cleaned with Smartseal Residue Remover prior to sealant application.**
APPLICATION: Shake container well before use. Apply by pressure sprayer, roller, sponge or brush. Application on vertical surfaces should be to full saturation commencing at the bottom and working upwards. Do not apply in damp conditions and only apply to dry surfaces in temperatures above 13°C and no higher than 23°C. It is very important to make sure no rain is forecast for at least 8 hours after application.
Applying one coat to saturation is normally sufficient. For best results, apply one coat to saturation and once touch dry, a 2nd lighter coat can be applied ('wet on wet' finish). If over application does occur on either coats, excess sealer can be removed with a dry roller or sponge. Ensure this is done within 45 minutes.
All equipment should be cleaned with water immediately after use.
SHELF LIFE: Store away from direct sunlight and sources of heat. Protect from frost.
12 months shelf life (in original sealed container). Once opened use within 3 months.
