ADDITIX P Liquid Thixotropising Agent 15kg

Mapei ADDITIX P – Liquid Thixotropising Agent for PURTOP EASY Waterproofing Membrane

Mapei ADDITIX P is a solvent-based liquid thixotropising agent developed specifically for use with Mapei PURTOP EASY polyurethane waterproofing membrane. When added at the manufacturer's recommended dosage, it increases the thixotropic properties of the membrane, helping control application consistency and improve workability on vertical and inclined surfaces.

ADDITIX P is particularly useful for professional waterproofing applications involving sloped surfaces, upstands and details where greater control of the liquid membrane is required. It helps reduce sagging and dripping during application while maintaining the intended performance of the compatible PURTOP EASY system.
