An anti-slip treatment for ceramic and porcelain tiles. 4-6 m² per litre; the manufacturer states the anti-slip effect lasts 6 to 24 months. pH 3 - test on a section of floor first.
Surface
Concrete and floors
The surface the manufacturer intends this preparation for.
R-9C improves the grip of ceramic and porcelain tiles - floors where water or grease turn a smooth surface into a hazard.
The manufacturer gives two figures that decide the purchase: coverage of 4-6 m² per litre and an anti-slip effect lasting 6 to 24 months. This is a periodic treatment, not a one-off.
The product has a pH of 3 and is ready to use. A test on a section of floor is obligatory - on a glazed tile the treatment acts on the surface of the glaze.
Concrete accepts a sealer only when it is dry, clean and seasoned. A fresh slab is still giving off mix water and will push any coating off with it.
A new floor and fresh precast units have to season. Manufacturers give that period on the data sheet; for precast concrete it is usually around 28 days.
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.
Products that form a polymer layer bind the loose particles on the surface, and manufacturers describe them as dust-free. That is not a substitute for a hardener where the concrete itself is dusting because it was poorly floated - the problem is then in the slab, not on it.
Yes, if the technical data lists indoor use. With solvent-based products you have to ventilate during application and for the period the manufacturer states.
Remove them before sealing, with an oil stain remover. A sealer applied over a stain seals it in and fixes it - oil will not evaporate through a sealed layer.
It limits the ingress of water and the salts dissolved in it. How far that goes depends on the product, and we quote it from the manufacturer's data sheet rather than generalising.
By material. R-9C is for ceramic and porcelain tiles, R-9G for granite and gneiss tiles. They also differ in pH (3 against 3.5) and coverage (4-6 against 5-8 m²/l).
The treatment acts on the surface of the glaze, so on high-gloss tiles the difference can show. That is why a test on a section - under furniture or in a corner - is a condition here, not a suggestion.
The manufacturer gives a range of 6-24 months with no indicator. In practice traffic and the way the floor is cleaned decide; the treatment is repeated when the floor starts to be slippery again when wet.
The technical sheet and safety data sheet will be available after approval.
