Product Description

Smartseal black limestone sealer is a highly-effective solvent-based sealer and re-colourant for black limestone which gives a transformative effect.

Limestone slabs will often fade over time and gradually turn a lighter shade of grey. The black limestone sealer can transform the look of faded limestone patios and make them look like they were recently laid. The sealer can be re-applied at any time to ensure any limestone slabs on patios or other external surfaces look good at all times.

Technical

Preparation:

  • Clean surface using a pressure washer and/or Patio Clean Xtreme.
  • Allow to dry for a minimum of 72 hours
  • Apply above 12C with a temperature no higher than 23C
  • Two coats are recommended
  • Apply by roller
  • Coverage: Average coverage approx. 4 - 5m/litre first coat (dependant on surface) and approx. 6 - 8m/litre second coat

Always apply to a test area first to determine suitability. A sample size (150 ml) is available for purchase should you wish to try it before committing to purchase 5 Litres.

***PLEASE NOTE*** - For best results, if a sweep-in jointing compound has been used when the slabs were laid, we would recommend using the residue remover prior to application.

Product FAQs

Q: I have recently purchased the black limestone sealer and applied the first coat to my patio. It looks great but there are dirty footprints everywhere. I want to get rid of those before applying a second coat. Is the patio cleaner extreme the best product to use? Is that harmful to cats & dogs?

Perry Mears

A: The foot prints should just clear with soapy water or a household cleaner. The Xtreme cleaner would not be required for this purpose. Hope that helps

Response from Jake

Q: Is white spirit appropriate for cleaning tools & equipment after use? If not, what would you recommend?

Peter

A: You would need to use our 'tool cleaning fluid' white spirit will not be strong enough to break down the resins in the black limestone sealer. It is best just to allow the roller to dry and store for future use. Once submerged back into the sealer for a few minutes, it will soften up, ready to be used again. Hope that helps.

Response from Nigel

Q: My black limestone slabs are very pale. I have tried your black limestone sealer, but it is too black, and the impregnating limestone sealer doesn't change the colour at all. Can I mix together? Or add water to black limestone sealer?

Marilyn Hawkey

A: Unfortunately you cannot mix both together as one is a solvent based sealer and the other is a non-solvent. The chemistries of both sealers are not compatible. You aslo cannot add water to the black limestone sealer.
