Customer Reviews

I've been fighting a losing battle with my limestone patio as it is very porous and is easily stained. It is so delicate that a jet was can damage the surface so I was looking for a product that would help protect the stone. I first used Smartseal's Drive clean Xtreme which was fabulous. Applied, waited an hour and used a hose and a brush. After leaving the patio for three days I then applied the Natural stone sealer using a spray. Couldn't have been easier.

Seal and protect a limestone patio or floor

Can be used externally or internally

Impregnating sealer for Limestone slabs and floors

Smartseal Limestone Sealer is a high quality, clear, solvent free acrylic impregnating coating system. Application of the sealer will alter the chemical structure of the porous limestone providing a excellent water repellent and stain resistant surface.

  • One coat application to saturation, or (for best results apply 2nd coat 'wet on wet')
  • 1 x 5 litre will treat up to 40 m
  • Resistant to algae, lichen and staining
  • Will leave surface "Dry/Natural"  dependent on porosity of surface
  • Average coverage: 1st coat 5 - 8 m per litre, 2nd coat 8-16 sq/m (dependant on porosity and finish of the surface)
  • Touch dry in 2 - 3 hours
  • Fully waterproof 24 hours
  • Lifespan of approx. 5 years can be expected


Technical

PREPARATION: Prior to application of limestone 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 required, fully clean off using pressure washer and leave to dry thoroughly for at least 3 days.

Always test product on-site, in an inconspicuous area, to ensure you fully are satisfied with the final appearance/ colour of the surface. 

**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: Shake container well before use. A suitable pressure sprayer, roller, sponge or brush 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. Do not apply in damp conditions or at temperatures below 13-23C. 

Applying one coat to saturation is normally sufficient. For best results, apply one coat to saturation and once touch dry, a 2nd lighter coat can be applied ('wet on wet' finish). 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.

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.
