The limestone around the indoor pool needed some love and this sealer did it perfectly

By Lawrence Tracey

Perfect. The sealer goes on easily, no noxious fumes, no mess. Cleans up easily. My limestone paving looks great. Shipping was quick but quite expensive.

By Dean Hillyard

Brilliant product. Easily applied with ordinary garden sprayer. Two coats of the limestone sealer applied same afternoon and dries real quick. Super fast delivery. Will use again.

Product Description

Colour Enhancing Impregnating sealer for Limestone patios and floors

Protective impregnating sealer for Limestone patios 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.

The sealer will give a colour enhancing effect once dry to bring out the original colour of the Limestone.

  • 1 x 5 litre will treat up to 30 - 50m on average
  • Highly resistant to algae, lichen and staining
  • Will leave surface 'damp' or 'wet' looking dependent on porosity of surface
  • Average coverage 6 - 10 m per litre first coat and 10 - 20 m per litre second coat, dependent on porosity and finish of surface
  • Application by roller or sprayer or suitable cloth
  • Touch dry 2-3 hours
  • Fully water-resistant in 24 hours
  • Lifespan of approx. 5 years can be expected
  • Suitable for Limestone can be used externally or internally



PREPARATION: Prior to application of limestone 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 a appropriate cleaning product.

**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 being fully cleaned with Smartseal Residue Remover prior to sealant application.**** Please get in touch for further advice.

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.

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) 

For internal surfaces application by a suitable cloth is appropriate.

Average coverage: 6 - 10 m per litre depending on porosity of the Limestone.

Important: Remove any excess within roughly 45 minutes, this can be done with a dry cloth or sponge.   

Do not apply in damp condition, aim for sealing temperatures between 15C - 23C. Shake container well before use.

All equipment should be cleaned with water immediately after use.

SHELF LIFE: 12 months (in original sealed container).

Store away from direct sunlight and sources of heat. Protect from frost.

Product FAQs

Q: Hi, I would like to use this on our black limestone patio. We have used a sweep-in semi permeable grout - can we just roller over the grout or do we need to try and keep the product just on the limestone slabs?


A: The limestone sealer will not damage the pointing, but it would make it less permeable.
