Natural looking matt effect sealer for natural stone slabs, pavers and tiles

Natural Stone Colour Enhancer seals & colour enhances natural stone & tiles leaving a natural matt finish. This natural stone sealer is suitable for sandstone, slate, limestones, block pavers and other porous surfaces. It can be applied to interior and exterior surfaces where a breathable, natural but enhanced appearance is desirable. This product is an impregnating solution which becomes meshed into the pores of the stone. Once dry, the surface becomes resistant to water and oil-based staining. The solution also contains a secondary element which deepens natural colour. It is highly suited to sealing colourful stone like Indian sandstone and York sandstone slabs. Natural Stone Colour Enhancer will also seal & deepen the colour of slate, grey limestone and clay pavers. Natural Stone Colour Enhancer can be applied to any porous surface which appears more attractive when surface colours are deepened.  A little like being very slightly damp but without a shine, thus preserving a more natural appearance.

Reduce maintenance by sealing out dirt, grime and organic deposits

When applied to external surfaces this natural stone sealer will inhibit organic growth like moss, algae & black spot lichens. Its application reduces the need for maintenance. You will still be able to jet wash the surface and apply periodic cleaning solutions. To apply this product we recommend using a pump up sprayer, masonry style textured roller or brushes in conjunction with microfibre cloths. Use microfibre cloths to remove any excess product. Natural Stone Colour Enhancer should be applied to saturation, we recommend working in manageable sections. Excess sealer (you may see some) should be removed within 20 – 30 minutes, possibly longer on cooler days. This product is an impregnator so will become meshed into the surface, it is not to be allowed to dry on the surface. The excess is usually located in the low areas of the stone and can easily be removed with a dry cloth or dry roller. We also stock a range of cleaners for internal and external natural stone floors. These can be used to remove grout haze, dirt, grime, black spot lichens and moss. Floorseal Sealer Residue Remover is a water-based cleaning solution for the removal of dirt grime, oils & waxes. We recommend using this product as a pre-cleaner if you have used a brush in compound (for exterior surfaces). It removes the resinous slick either side of the joint which makes the surface non-porous. It is not for the removal of compounds where mistakes have been made i.e. obvious staining and heavy contaminations. Floorseal Black Spot Remover Plus is for removing black spot lichens from external surfaces. It will also remove all other organic contaminations. Floorseal Stone Floor Cleaner for deep cleaning internal surfaces prior to sealing.

  • Can I use Natural Stone Colour Enhancer as a pre-sealing prior to grouting or pointing?

    We do not recommend using this product as a pre-sealer.

  • Why do subtle colour enhancers work best on colourful sandstones?

    Slightly colour enhancing sandstones simply enhances the colour which is already present within the stone. The sandstone will still look totally natural but with slightly increased colour. If you over colour enhance sandstones they can become dark or patchy.
