Data sheet

Available in 25kg paper sacks, with a shelf life of 6 to 8 months. Store in a cool dry place.

Approximately 1.7kg per mm of thickness over 1m². One 25kg bag will cover approximately 1m² at
15mm thickness. This does not include any allowance for wastage.

Surface Preparation
The background must be level, well keyed and dampened to control suction. Forte Render Base Coat is only for application to
porous backgrounds such as masonry – do not apply over old paints or similar substances. Ensure the
background is free from dust, oil or contaminants. If necessary clean down with dilute brick acid or
fungicide before rendering. Tape up and protect windows and joinery.

How to Mix
One 25kg sack of Forte Render Base Coat will need approximately 4 litres of clean water. Mix for between 3 to 10 minutes using
a drum mixer or drill and whisk. Do not re-work. Working time is between 1 and 2 hours.

Dampen the background to prevent rapid water loss from the undercoat render. Do not use in temperatures
below 5°C or above 30°C and do not apply in direct sunlight.
Do not overwork or polish Forte Render Base Coat. Typically apply in coats of around 10mm. For a thickness greater
than 15mm apply in 2 coats. Key the render before each further coat is applied
