Desmothix – Thickening Additive for Upstands & Vertical Applications
Optimized for Vertical & Sloped Surfaces in Waterproofing Systems
Desmothix is a polymeric rheology modifier (thickener) specifically developed as a liquid additive for Desmopol polyurethane membranes. It enhances application on vertical and sloped surfaces by preventing run-off and ensuring uniform thickness. Ideal for new construction and refurbishment projects, Desmothix allows seamless, waterproof, and fully adhered membranes to be applied without sagging.
Key Benefits:
✔ Enhances Vertical Application – Prevents membrane sagging on upstands, slopes, and complex details.
✔ Maintains Waterproof Integrity – Ensures uniform coverage for a fully watertight system.
✔ Compatible with Desmopol Membranes – Works seamlessly with single-component, moisture-cured polyurethane coatings.
✔ Versatile Application Methods – Can be rolled, troweled, or sprayed for efficiency.
✔ Optimized Drying Time – Allows controlled curing without compromising performance.
