TRADECO ®
A binder for 7N and 3.6N masonry units mortars BS EN 459.1 HL3.5
Specifically designed to provide today’s builder with a mortar that DOES NOT develop a strength above the one of the masonry units. Elasticity, good water retention, setting time, low capillarity, excellent breathability are the other notable properties of mortars made with TRADECO ®. Its low density produces a high yield.
