Technical data
For 7N and 3.6N - BS EN 459.1 (HL 3.5)
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.

Mixing
Up to 5 minutes in a conventional drum mixer.
Application
Application by spray gun is possible. Please consult us.
Working temperatures
Not below 8oC or above 30oC. Make sure that high suction materials are thoroughly dampened before application. Avoid rapid drying due to high temperatures or strong winds by curing with a light water mist several times a day if necessary. See Protecting Lime Mortar.
