surface preparation

Surface preparation

Ensure areas are clean, dry and free from flaking material, oil and grease. For gloss surfaces lightly sand to provide a key, then using a damp sponge remove the dust and allow to dry. Apply a coat of Thistle GypPrime or Thistle Bond-it for pre-treatment where necessary.

plaster mixing


Add approximately 8 litres of clean water per bag to a mixing bucket and gradually add the plaster whilst mixing to a preferred consistency.

first application

First application

Apply the first coat at 2–3mm and flatten without removing material. Allow to firm up (approximately 40 minutes on wallboard).

second application

Second application

Then mix a fresh batch of magnetic plaster and apply second coat at 1–2mm thickness. Trowel up as needed and avoid over polishing using water, but keep the trowel damp.



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

magnetic plaster coverage

Magnetic attraction

The magnetic attraction of a wall coated with Thistle Magnetic Plaster is determined by the thickness of the material applied and the strength of the magnets used. A minimum thickness of 3mm is required to enable magnetic attraction.
