Thistle HardWall Installation Instructions (Spray Application)
Our guidance below shows the recommended way to apply Thistle HardWall Spray. All times stated are approximate.
Thistle HardWall Spray is ideal for most medium to high suction backgrounds, including masonry such as bricks and aircrete blocks. The plaster even helps to keep efflorescence away from the surface so that there's one less thing to worry about.
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: If the overall thickness exceeds 25mm, metal lathing will need to be fixed into the substrate in order to support the additional weight.
For very high suction backgrounds: Ensure adequate suction control with water takes place prior to application.
