Designed to meet the needs of demanding industries and environments
Heritage
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.
Stones and Bricks
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.
Renders
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.

Everything you need to know about EXOCOAT™ SH
What is EXOCOAT SH?
EXOCOAT SH is a superhydrophobic specialty coating designed to impart extreme water repellency to mineral surfaces. It creates a durable, invisible layer that significantly reduces water absorption and prevents staining, while maintaining breathability of the substrate.
What are the main benefits and features?
Provides superhydrophobic effect (water contact angle >140°); Reduces water ingress and freeze-thaw damage; Maintains substrate appearance (transparent finish); Improves durability and reduces maintenance; Environmentally friendly formulation.
Is EXOCOAT SH an end product or a formulation component?
EXOCOAT SH shall be mixed with water before use. Mix in water: EXOCOAT SH:Water = 1:9.
On what substrates can EXOCOAT SH be applied?
Ideal for mineral-based surfaces such as concrete, stone, brick, and porous masonry. Also suitable for roof tiles and facades where water repellency is critical.
How is EXOCOAT SH applied?
Apply by low-pressure spray, brush, or roller on clean, dry surfaces. Ensure uniform coverage without pooling. For large areas, spray application is recommended for efficiency.
What is the drying and curing time?
Surface dry within 30–60 minutes at ambient conditions. Full water-repellent effect develops after 24 hours. Avoid rain exposure during initial curing period.
What is the shelf life and storage advice?
Shelf life: 12 months in unopened container. Store in a cool, dry place between 5–25°C, away from direct sunlight and sources of ignition.
Is EXOCOAT SH safe and compliant?
Compliant with major environmental regulations (REACH, RoHS). Free from heavy metals and hazardous substances. Refer to SDS for detailed safety information.
What packaging sizes are available?
Available in 5 kg cans, 25 kg drums, and 200 kg drums for industrial applications.
