A solvent-based sealer for marble worktops, sills and floors. It changes neither the colour nor the polish of the stone. Afterwards the manufacturer recommends cleaning products of pH 5-9.
Surface
Natural stone
The surface the manufacturer intends this preparation for.
SM-1 is a colourless sealer for marble - worktops, sills, floors and cladding.
Marble is soft and sensitive to acids: a drop of lemon or vinegar can etch a matt mark into the polish. A sealer limits the ingress of liquids into the stone, but does not change its chemical resistance - spilled acid is not worth leaving there, sealed or not.
The product is solvent-based, applied in one coat with a soft roller and then polished. After sealing, the manufacturer recommends cleaning products of pH 5-9.
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.
After sealing polished stone, manufacturers require the surface to stay out of use, usually for 72 hours. The exact figure is under "Technical data".
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.
Chemistry and finish. The -1 versions are single-component, siloxane-based and dry colourless. The -2 versions also contain modified silanes and deepen the colour for a wet-stone effect. Protection against water is the job of the product in both cases; what separates them is the finish.
Do not assume so. Marble is soft and sensitive to acids, granite is not - the manufacturer states the stone in the product's intended use, and our categories follow that. Every product lists its recommended substrates in the technical data.
Manufacturers of the polished-stone range state a permitted pH range for cleaning products - usually pH 5-9 for the invisible versions and wider for the wet-look ones. The figure for each product is under "Technical data".
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.
The product bonds with the stone slowly, and during that time the surface takes marks easily. The manufacturer also warns that after eight hours marks from shoes, knee pads or uneven polishing can no longer be removed.
Yes. This is a solvent-based product and the manufacturer requires good ventilation during application and for 72 hours afterwards.
It limits the ingress of liquids, so the stain sits on the surface longer and can be wiped off. It is not an absolute barrier - the sooner you wipe, the better.
SM-1 does not change the look of the marble. SM-2 deepens its colour - on marble that is a significant change, because it affects the veining as well. On pale marble the result can be surprising, so a test is obligatory.
The technical sheet and safety data sheet will be available after approval.
Enter the area and how absorbent the substrate is. We work out the litres and the packs.
The manufacturer's figure is for polished stone; on a more absorbent material it will be lower.

An impregnation will not bond to a surface with anything left on it. This is the most common cause of complaints.
