What is Thistle Spray Finish?
Thistle Spray Finish is a gypsum setting plaster, its characteristics are very similar to British Gypsum’s other finishing plasters. The product has been designed for spray application by worm pump spray machines (e.g. m-tec’s M100-SC or PFT’s Ritmo). The product is applied as a skim coat to a thickness of 2mm.
What backgrounds can Thistle Spray Finish be applied to?
Thistle Spray Finish is designed for plasterboards and for backgrounds treated with Thistle Bond-it (e.g. MR boards, flat concrete etc). It is not designed to resist the suction from undercoat plasters.
What is the setting time of Thistle Spray Finish?
The setting time is a little longer than Thistle Multi-Finish by around 15 minutes. The longer setting time helps the plasterer keep control of larger areas covered. The set is very gradual allowing plenty of flexibility around the flattening and trowelling operations. The final trowel is carried out at around 110 minutes.
What is the coverage per bag of Thistle Spray Finish?
11m² per 25kg bag based on a 2mm thickness. The figure allows for some excess use e.g. in tapered edge joints etc, but it does not include waste. A small amount of waste is inevitable at the beginning and end of the day during machine setup and cleaning. Such waste material is likely to be used up for the more intricate areas of the job such as window reveals. The coverage of other Thistle finishing plasters (Thistle Multi-Finish, Thistle Board Finish and Thistle Durafinish) is 10m² per 25kg bag.
Can Thistle Spray Finish be applied by hand?
Thistle Spray Finish is equally at home being applied by hand or machine. Nearly all machine jobs will have some areas for which spray application is impractical (e.g. window reveals).
What is the colour of Thistle Spray Finish?
Thistle Spray Finish is light grey in colour. It is manufactured at our Kirkby Thore site in Cumbria, where the mined gypsum seams are grey, giving the product its colour. Plasters that are manufactured at our East Leake and Barrow plants in the East Midlands are pink in colour because the gypsum seams mined there incorporate pink marl.
Do you need to sand the surface down once the product has been sprayed onto the wall?
No. Thistle Spray Finish is a traditional gypsum setting plaster. Once it has been applied on the wall it is finished by trowelling the surface flat.
What treatment is required prior to painting?
None. Thistle Spray Finish is a traditional gypsum setting plaster. Once the surface has been trowelled flat it is left to dry. Once dry the surface can be painted in the usual way.
How much is a 25kg bag of Thistle Spray Finish?
Thistle Spray Finish is available from all good merchants and distributors. Please request a price from your local branch.
Can I spray Thistle Durafinish?
Yes. Thistle Durafinish can be applied by worm pump spray machines in the same manner as Thistle Spray Finish.
Can I spray Thistle Multi-Finish or Thistle Board Finish?
No. Thorough testing, both laboratory and practically based, prove that there is unacceptable risk of adhesion failure between the substrate and plaster.
