The right seal for travertine.

No. MineralProtect is colourless and non-pigmenting. Same colour, same finish, same feel. The only change is that water and oil no longer grip the surface. This is a different category to the enhancer sealers you may have been offered, which are formulated to deepen the stone to a wet look. If keeping the exact travertine you chose is the point, that is exactly what a colourless surface coating is for.

No, and any sealer that claims to is overpromising. Travertine is carbonate stone, so acids dissolve the surface itself. That is etching, a physical mark in the stone, not a stain sitting on it, and no penetrating sealer prevents it because the acid reacts at the exposed surface without needing to soak in. What sealing does is slow absorption and buy you time, so the honest advice is to wipe up acidic spills promptly on the areas that see them.

A pool surround is the harshest exposure travertine gets: chlorine, UV, sunscreen, body oil and salt. It is also where our chemistry earns its keep. MineralProtect is inorganic, so chlorine and UV do not break it down the way they break down an organic film sealer, and it stays breathable and colourless, so unlike a film it doesn't trap moisture and salt beneath the surface. On a heavily salt-laden, reticulated surround we assess the stone first and tell you plainly what a surface treatment can and cannot do. See the limestone guide too, since Perth surrounds are often a mix.

Two clocks, kept separate on purpose. The easy-clean and beading you can see is the shorter one and fades first, so plan on a top-up over the years to keep it at full strength, and that top-up goes on clean stone with no stripping. Then there is the guarantee: a 10-year registered guarantee on the coating's repellency function, with re-treatment of the affected area as the remedy, sitting on top of your rights under Australian Consumer Law. When we assess your stone we give you the honest refresh interval for your surface and how hard it gets used, not a number picked to win the job.

Fair question, and the answer is a strength here. On travertine the coating anchors into the mineral and pore structure: the water-based sol wicks into the open pores and cures in place into a rigid mineral network keyed into the stone, backed up by the coating cross-linking into a solid within itself. Porous stone like travertine grips it in better, not worse. That is the opposite of dense, polished marble, which has almost no porosity and is the genuine hard case for any sealer. If you want the atom-by-atom version, the technical companion walks through it.

Yes, and any coating that says otherwise is overpromising. Sealing changes how the surface behaves: it repels water, resists oil staining and sheds dirt, so build-up is slower and washes off far more easily. You still give it the occasional clean, it is just much easier to keep looking right, and the marks that used to set in for good now tend to lift.
