An acrylic emulsion in an organic solvent for fencing, low walls and concrete elements. Applied in a thin, even coat; on very porous substrates the manufacturer advises a second coat once the first has dried.
Surface
Concrete and floors
The surface the manufacturer intends this preparation for.
EI-13 is intended for concrete fencing, low walls and vertical elements - that is, where the product has to soak in before it can run off.
The base is an acrylic emulsion in an organic solvent. The manufacturer advises a thin, even coat by brush or roller, with a second coat on very porous substrates once the first has dried.
Drying is quick: 60-120 minutes at around 20 °C. Coverage 7-10 m² per litre, working temperature 5-25 °C.
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.
Split-face blocks are very absorbent - the manufacturer provides for a second coat on such substrates. Allow for product at the lower end of the coverage range.
The manufacturer describes the product as a clear, colourless (slightly cloudy) liquid. The data sheet does not claim colour deepening, so we do not promise it - a test patch settles it best.
The technical sheet and safety data sheet will be available after approval.

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