EXOCOAT™ SH

EXOCOAT™ SH is specifically designed to protect heritage buildings while fully respecting their original appearance and materials. It provides effective water repellency without forming a film, allowing historic substrates to breathe naturally. The treatment helps prevent moisture ingress, which is a major cause of freeze–thaw damage, salt crystallization, and biological growth in old structures. EXOCOAT™ SH does not alter color, texture, or surface gloss, making it suitable for use on protected or listed buildings. Its long‑lasting performance supports conservation efforts by reducing maintenance needs and extending the life of historic façades.

When applied on stones and bricks, EXOCOAT™ SH significantly reduces water absorption while preserving the natural look of the substrate. By limiting moisture penetration, it helps protect masonry from deterioration caused by weathering, pollution, and cyclic wetting and drying. The coating maintains vapor permeability, preventing trapped moisture that can lead to cracking or spalling. EXOCOAT™ SH is suitable for both natural and engineered stone as well as traditional and modern brickwork. This durable protection contributes to longer service life and improved façade durability in demanding outdoor environments.

EXOCOAT™ SH enhances the durability of mineral renders by providing effective protection against driving rain and surface soiling. It reduces water uptake while allowing water vapor to escape, maintaining the balance between protection and breathability. By limiting moisture penetration, the coating helps prevent efflorescence, staining, and premature degradation of rendered surfaces. EXOCOAT™ SH integrates seamlessly with the texture and finish of the render without altering appearance. This makes it an ideal solution for extending the lifespan and aesthetic quality of rendered façades.
