This low-viscosity silicon-based treatment is intended for porous mineral substrates where a penetrating hydrophobic treatment is being evaluated rather than a heavy surface film.
Concrete, masonry, stone, mortar and repair substrates differ in porosity and moisture condition; a trial area is essential before broad application.

The supplied 2024 report summary records the stated submitted-sample observations. A separate 2025 report includes a note that some measured items were not judged against the standard because the tested substrate differed; those values are not used as public performance claims.

Handling / storage
Clean the substrate and remove loose material, contamination and standing water before a trial.
Apply evenly to saturation as appropriate for the substrate; confirm uptake and visual effect in a representative test area.
Selection limits
Not a crack-bridging membrane, structural repair material or a substitute for drainage design.
Performance can change with substrate porosity, moisture, contamination, cure and exposure; verify on the actual substrate.
It is a penetrating water-repellent treatment for appropriate porous substrates, not a substitute for waterproofing design where hydrostatic pressure or active defects are present.
Why is a test patch needed?
Mineral substrates vary greatly in porosity, moisture and contaminants, all of which affect absorption, appearance and performance.
