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 being applied to a recently laid external Limestone patio or path, where a "sweep-in" pointing compound was used, as a precautionary measure we advise the natural stone must be fully cleaned with Smartseal Residue Remover prior to sealant application.**** Please get in touch for further advice.
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.
If over application does occur, remove excess sealer with a dry roller or sponge within 45 minutes of applying.
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 12-15°C. Shake container well before use.
All equipment should be cleaned with water immediately after use.
