Description

FS SEALER PLUS is a ready-to-use, water-based blend of silanes and siloxanes that delivers deep-penetrating water repellency and impregnation for porous natural stone and mineral surfaces. Reacting with substrate moisture, it forms an invisible active barrier that reduces water absorption while preserving breathability. The formulation provides fast water repellency, alkali resistance, and a tack-free finish within 48–72 hours, covering 30–60 sq ft per litre.

FAQs

Can I recoat FS Sealer Plus immediately?

Yes. Use the wet-on-wet method: apply each subsequent coat as soon as the previous one is fully absorbed (no shiny film remains). This approach ensures the water-based sealer penetrates deeply and builds uniform protection.


Allow 48–72 hours drying time between application and light foot traffic. Full water-repellent performance and tack-free drying are achieved within this window, ensuring the breathable stone treatment cures properly without surface sheen.


FS Sealer Plus is ideal for porous natural stone, concrete, brick, and mineral-based substrates. Use it on marble, granite, sandstone patios, limestone facades, and engineered pavers to enhance durability and resistance to alkali and weathering.


Upon application, the silane siloxane molecules react with moisture in the substrate to form an active, water-repellent network. This silane siloxane sealer reduces water absorption while maintaining vapor permeability, protecting against moisture damage and freeze-thaw cycles.


Absolutely. This water-repellent protector withstands rain, freeze-thaw cycles, and UV exposure. Apply FS Sealer Plus on sandstone patios, limestone walkways, and concrete pavers to ensure durable outdoor stone protection.
