BLACK LIMESTONE SEALER 5L

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.

Preparation:

Clean surface using a pressure washer and/or Patio Clean Xtreme.
Allow to dry for a minimum of 72 hours
Apply above 12°C with a temperature no higher than 23°C
Two coats are recommended
Apply by roller
Coverage: Average coverage approx. 4 - 5m²/litre first coat (dependant on surface) and approx. 6 - 8m²/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.
