Installation Guidance

0 mins

  • Spray apply to an even thickness of approx. 2mm

5 - 10 mins

  • Within 10 minutes, flatten using a trowel or a spatula, without removing material. Air trapped at this stage will be released later

40 mins

  • Gradually flatten and finish using the same techniques as a hand-applied plaster

70 mins

  • 1st trowel

100 - 110 mins

  • Final trowel. Water should be used sparingly, if at all, and only in the latter stages of trowelling

Time and processes are given as guidance. On site practice may vary. Finishing times are reduced by suction and extended by cold weather conditions.

The most common way to mix and apply Thistle SprayFinish is using a worm pump plastering machine. To learn how to do this with your chosen machine, please refer to the manufacturer’s guidance. In general, the plaster’s consistency should be slightly softer than that used for hand application.

Note: Ensure that the product is suitable for the background to which it is being applied by using the Thistle Plaster Selector Guide.
