About this product
mach 3 is a next-generation liquid additive for semi-dry cementitious screeds, combining ultra-fast drying with outstanding strength enhancement. Its integrated processing aid optimises workability at every stage of application, enabling faster, easier, and more efficient installation.
The result: faster construction progress, superior screed performance, and maximum reliability on site.
