Frequently asked questions

No, it is a clear liquid that penetrates the surface and deepens the colour.

No, this product both seals and enhances the surface.

It soaks into the limestone to deepen colour. It is also a waterproofing sealer so will inhibit water and oil staining. It is a little like oiling wood to increase interest whilst retaining its natural appearance.

It will dry almost matt on the more porous limestones. It will create a low sheen satin finish on very dense black limestones.

Some brush in compounds can weather off over time – seek advice from the manufacturer. Very careful pressure washing can work. Do not hold the nozzle too close to the surface of the limestone or you can mark it!

The issue with brush in style compounds is that they are often non-porous. Therefore sealers cannot penetrate into the stone.

Brush in compound residues need removing before any attempt to seal the stone is made. If you are unsure you can always apply to a few slabs before proceeding to a full application of sealer.

With care! – do not use an acid! Soaking with water with long dwell times can help.

If it is just a residue very carefully pressure washing may work. Do not hold the nozzle too close to the surface of the limestone or you will mark it!
