PREPARATION: Prior to application of limestone sealer or natural stone sealer ensure surfaces to be sealed are 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, the natural stone must be fully cleaned with an acid wash/effloresence remover prior to sealant application.**

APPLICATION: A suitable pressure sprayer or roller is recommended taking care to avoid any pooling. Application on all substrates should be to full saturation and on vertical surfaces commence at the bottom and work upwards.

For internal surfaces application by a suitable cloth is appropriate.

One application is normally required, for best results, apply light 2nd coat, within 30 minutes of first application. Do not apply in damp conditions or at temperatures below 5°C. Shake container well before use.

All equipment should be cleaned with water immediately after use.
