Product Reviews
By Gavin Simmons

Happy with the sealer its brought the limestone up nicely.

By Adrian WurrFROM Banbury

Helpful webchat advice to suggest a sample to test compatibility with whatever sealer was used previously. Coverage consistent with product guidance. Easy to apply (I used a mop) and nice finish, but after just a few days, impossible to assess how well it will wear.

By John BriggsFROM Sheffield

A good product which served its purpose

Technical

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 NOTE: 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. 

Depending on the stone/surface, more than one coat may be required. For most porous stones, a 2nd lighter coat can be applied once touch dry (slightly wet). 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.

  1. Shake container well before use
  2. Ensure that surface area is completely clean from dirt & grime.
  3. Allow surface area to dry, will take 2-3 dry days depending on the weather.
  4. Apply 1st coat to saturation by roller, sprayer or brush.
  5. Apply 2nd lighter 'mist' coat (approx 45 minutes after 1st coat if suitable).
  6. If over application does occur, please remove excess sealer with a dry sponge or cloth.
  7. Avoid walking on surface 4 hours after application and 24 hours for heavy traffic.

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.
