Prior to application of sandstone sealer or natural stone sealer ensure surfaces to be sealed is clean, dry and free from contamination. If algae or stains are present pre treat prior to cleaning with a appropriate cleaning product. **If applied to a surface where a "sweep-in" pointing compound has been used with the last 6 months, the natural stone must be fully cleaned with Smartseal Residue Remover prior to sealant application.**


A suitable pressure sprayer or roller is recommended taking care to avoid any pooling. If over application does occur, excess sealer can be removed with a dry roller or sponge. Ensure this is done within 45 minutes. Application on vertical surfaces should be to full saturation commencing at the bottom and working upwards. One application to saturation is normally sufficient, but for best results, apply 2nd \\'wet on wet\\' coat within 30 minutes. Do not apply in damp conditions and only apply in minimum temperatures of 12- 15°C. Shake container well before use. All equipment should be cleaned with water immediately after use.
