SHP for Wall Putty
Tenessy Silicone Hydrophobic Powder for Wall Putty
Tenessy Silicone Hydrophobic Powder (SHP) is an advanced waterproofing additive engineered specifically for wall putty and cement-based coating systems. It enhances water repellency by forming a durable, breathable, hydrophobic barrier within the putty layer. This innovative solution not only prevents moisture penetration but also allows vapor to escape—ensuring long-term protection, better adhesion, and improved finish quality.
As a trusted chemical additive manufacturer in China, Tenessy delivers industry-leading silicone hydrophobic technologies to the global construction market, supporting wall putty manufacturers with reliable, customizable, and high-performance solutions.
How Does SHP Work in Wall Putty?
When added to wall putty formulations, Tenessy SHP reacts with the cement or gypsum matrix to form a siloxane-based hydrophobic network. This network lines the pores and capillaries of the wall surface, dramatically reducing water absorption without sealing the surface completely.
The result is a “breathing” hydrophobic layer—water is blocked from entering, while moisture vapor can still pass through. This mechanism keeps walls dry from the inside out, prevents cracking caused by trapped moisture, and improves the overall lifespan of both interior and exterior coatings.
SHP Specification & Usage Instructions
- Appearance: White free-flowing powder
- Composition: Siloxane-based compound with dispersion and adsorption mixture
- Fineness: 200 mesh (98% pass rate)
- pH Value: 10–12
- Recommended Dosage: 0.16–0.3% of total dry weight
How to Use Tenessy SHP in Wall Putty
- Dry Mix with Other Raw Materials
Add the Silicone Hydrophobic Powder directly into the dry-mix formula of wall putty along with cement, fillers, and other additives. Ensure uniform distribution using standard mixing equipment. - Add Water and Mix
Slowly add the dry mix into clean water while stirring. Avoid over-agitation or high-speed mixing to minimize air entrapment. - Resting Time
After mixing, let the mixture rest for about 5 minutes to allow SHP to fully activate, ensuring optimal hydrophobicity and consistency. - Application
Apply the wall putty as usual. Once dry, the treated surface will show excellent water repellency and improved surface quality.
Benefits of Using SHP in Wall Putty
- Outstanding Water Repellency: Creates a powerful waterproof layer that prevents rain, humidity, and surface dampness.
- Enhanced Durability: Reduces water-induced damage such as blistering, cracking, and peeling of the topcoat.
- Superior Beading Effect: Produces a visible water-beading surface—water droplets roll off instead of being absorbed.
- Long-Lasting Protection: Maintains hydrophobic performance over time, even after multiple wet-dry cycles.
- Excellent Compatibility: Works effectively with cement-based, gypsum-based, and polymer-modified wall putty systems.
