Renders and Plasters

Rendering and plastering work is made easy and economical by the availability of a coloured range of ready mixed mortar normally spray applied (manual application also possible). Coloured mortars eliminates the need for painting.

The range of mortars has been developed by St. Astier limes and specifically formulated to achieve high workability, elasticity and breathability and low capillarity , water absorption and shrinkage. These products are well proven and in use for over 30 years. They conform to BS 998.1 and carry the relevant CE Mark. They are subject to quality control by the relevant Authority (level 1+), contrary to some products that have only the Manufacturer declaration of conformity (level 4).

St. Astier One Coat renders and plasters are applied directly onto the clay blocks by spraying (or manually).

They offer a durable protection in all climatic conditions thanks also to their water proofing qualities.

Available in different gradings as follows:

TF 0 to 1.3mm
F 0 to 1.8mm
M 0 to 2.5mm
G 0 to 4mm

The thickness in one pass can be up to 15mm and the coat is straightened and floated immediately after application.

The final finish (sponge, plastic or wooden float, trowel scratched etc.) is performed after a few hours. The whole system is designed to be completed within 24 hours.
