Application recommendations

Building, pointing, rendering and plastering mortar for restoration work and new build.

In rendering used mainly as a coloured finishing coat. Undercoats should be made using NHL 5 or NHL 3.5. Key the undercoat to accept the Colorchausable finishing coat by using a devil float. Apply the finishing coat once the undercoat is dry. Dampen background before application. In exposed hot weather, cure for 2 to 3 days by applying a water mist two or three times a day. Protect from frost, rain and drying wind and direct strong sun until sufficiently hard. See "Protecting Lime Mortar".

Application by spray gun: possible. Please consult us.

Preparation. Mix in a cement mixer for about 5 minutes adding clean water to obtain required workability
(approx. 6-7 litres of water per bag of Colorchausable).
