Technical
PREPARATION: Due to the effects of Efflorescence and Natural Salts and Minerals, that can permeate through Natural Stone, it is recommended not to seal for a minimum 4 months after installation. Prior to application of sandstone 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 an appropriate cleaning product.**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: 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. Remove any excess after approx 30 - 40 minutes.

- For best results, apply one coat to saturation, and once touch dry (normally around 45 min), apply a second coat "wet on wet" (which means before the 1st coat has totally dried)
- Do not apply in damp conditions
- Application temperature range: 15° to 23°C
- Shake container well before use.
