Data sheet

Available in 25kg paper sacks, shelf life 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 thick. This does not include any allowance for wastage.

Surface Preparation
The background must be level, well keyed and dampened to control suction. Only for application to
porous backgrounds such as masonry – do not apply over old paints or similar. 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 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 render. Do not use in temperatures
less than 5°C or over 30°C and do not apply in direct sunlight.
Do not over work or polish Forte. 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
