One coat render
MONO ST ASTIER - ONE COAT RENDER
A ready mixed mortar based on Natural Hydraulic lime specially formulated to achieve excellent waterproofing, low capillarity, high breathability, elasticity and vibrant coloured finishes. Substantial savings in cost of painting and maintenance are achievable.
Application recommendations: on properly prepared background offering adequate keying, cast on or spray on up to 10 mm in one pass for floated finishes or 15 mm if a scratched finish is required.
On waterproofed or smooth backgrounds spray or cast on a 1st bonding coat of about 3 mm adding 500 grams of SBR per bag of product.
Straighten the work immediately after with an appropriate tool. Float (sponge, wooden or plastic) after 2-3 hours or more depending on weather conditions. Not suitable for light weight, porous cement blocks.
Packing: in 30 kg. bags / 49 bags per pallet.
