45 - 90 mins
- Flatten off with the appropriate tool for size of the job (i.e. trowel or rule)
120 - 150 mins
- Continue to flatten and when firm scour with sponge float to raise fat to the surface. Trowel progressively to a smooth, matt surface The sponging can be done 2-4 times, depending on the finish required
Times and processes are given as guidance. On site practice may vary. Finishing times are reduced by suction and extended by cold weather conditions.
NOTE: Maximum thickness is 25mm, built up in layers of around 8mm. If overall thickness exceeds 25mm, metal lathing will need to be fixed into the substrate in order to support the additional weight. Use the Thistle Plaster Selector Guide to ensure that your chosen product is suitable for the background that you are applying it to.
For very high suction backgrounds: Consider applying a layer of 3mm to help control suction first, then build up with another 8mm layer to complete as per instructions above.
