FS DEEP IMPREGNATOR
Solvent-based water repellent for long-lasting protection of porous natural stone surfaces.
Description
FS DEEP IMPREGNATOR is a ready-to-use, solvent-based impregnator composed of silanes and siloxanes, designed to protect mineral and alkaline surfaces from water absorption. It penetrates deep into porous substrates, reacts with moisture to form a durable barrier, and retains the material’s breathability by allowing trapped vapors to escape.
The formula resists alkalis, dries tack-free, and can be applied even on slightly damp surfaces, making it ideal for long-term surface preservation.

FAQs
Can I treat slightly damp surfaces with this stone sealer?
Yes. FS Deep Impregnator’s formula works on slightly damp stone or concrete, reacting with inherent moisture for rapid water-repelling action. Always test a small area first to confirm proper absorption and finish.
How long does FS Deep Impregnator take to cure?
Allow 48–72 hours for full cure, depending on temperature and humidity. This curing window lets the solvent-based treatment develop its alkali resistance and hydrophobic barrier fully before light use or overcoating.
Is FS Deep Impregnator resistant to alkaline environments?
Yes. The silane siloxane chemistry delivers alkali resistance, making it perfect for fresh concrete, mortar, or mineral paints. It forms a durable barrier that withstands high pH without compromising water repellency.
Can FS Deep Impregnator be used as a primer for exterior paints?
Yes, after curing, FS Deep Impregnator creates a stable, water-repellent concrete primer that improves adhesion for exterior paints and coatings. Always ensure the surface is dry to the touch before overcoating.
Does FS Deep Impregnator darken or change surface appearance?
Most mineral substrates remain visually unchanged; however, slight darkening can occur on highly porous stones. Always perform a small visual impact test to confirm how the solvent-based sealer affects your specific stone or masonry.
