Anti-slip treatment for granite and gneiss tiles R-9G CTS Chemistry

Reduces slipperiness on granite and gneiss tiles. Treat at +10 to +25 °C, keeping the surface out of direct sun and rain; one litre covers 5-8 m². The anti-slip effect lasts 6 to 24 months (manufacturer's data).

R-9G is the anti-slip treatment developed for granite and gneiss tiles - stone that is harder and less receptive than ceramics. That is why it has a different pH (3.5) and higher coverage: 5-8 m² per litre.

The anti-slip effect lasts 6 to 24 months (manufacturer's data) - a periodic treatment, as with the ceramic version.

Work at +10 to +25 °C, and protect the surface from direct sun and rain during application.

Stone forgives less than concrete. An acidic cleaner used on marble or travertine will etch the surface irreversibly, and excess sealer on a polish leaves a smear that can no longer be removed.

  1. Match the cleaner to the stone. Marble, travertine and limestone are sensitive to acids - for those, neutral or alkaline products are the right ones.
  2. Remove waxes, polishes and polymer coatings. A penetrating sealer will not get through a layer of wax.
  3. Dry the stone all the way through and check that no moisture is being drawn up through the joints.
  4. On polished surfaces have a clean, soft cloth ready to lift the excess - you have minutes, not hours.
  5. Ventilate well when working with solvent-based products.

After sealing, polished stone usually stays out of use for 72 hours.

Before sealing the whole area, test on a patch hidden by a planter or in a corner of the patio. The same product can read differently on two batches of the same material, and on a surface with old coating left on it, it will not bond at all.

Can I use a granite sealer on marble?

Not always. Marble is soft and sensitive to acids, granite is not, so the product has to match the type of stone. Before you buy, check that marble is on the list of recommended substrates.

How do I clean stone once it has been sealed?

With cleaning products of the right pH. For the polished-stone range that is usually pH 5-9 for the invisible versions, and a wider range for the wet-look ones. You will find the range for your product in its technical data.

Will sealing stop the stone yellowing?

It helps, though not in every case. It limits the ingress of water and the compounds dissolved in it, including those that discolour stone from below. It will not stop processes inside the stone itself, or rust from fixings.

Will it work on polished granite?

Yes - R-9G is for granite and gneiss tiles whatever their finish. On a polish, though, start with a test on a small, inconspicuous area - a polished surface is the first to show any change in appearance.

Can I use it instead of Guard Slip Resistant?

Not always - they work in two different ways. R-9G is acidic at pH 3.5 and gives an effect lasting 6-24 months. Guard Slip Resistant reacts with the silica in the material and gives a long-lasting anti-slip effect. If your stone is sensitive to acids, choose the latter.
