What is the crystalline silica content of Gypsum plasters?
The natural Gypsum that makes up our Thistle plaster range varies slightly in composition from site to site due to natural impurities in the surrounding rock, one of these impurities is quartz, a form of crystalline silica.
Thistle GypPrime can be diluted, normally a ratio of 1:5 parts water provides adequate suction control, or it can also be used neat if necessary to control extremely severe suction. One tub covers up to 600 sqm (diluted 1:5) or 100 sqm undiluted.
A 25kg bag of Gyproc DriWall Adhesive is suitable for two 1200x2400mm plasterboards under normal use, however more adhesive will be required if the background is not plumb or straight.
Plastering on existing painted walls is only possible if the paint and the substrate in which the paint is applied are both in very good condition.
In terms of adhesion and cleanliness, and with the application of Thistle Bond-it prior to plastering. We suggest carrying out this procedure on a trial area to determine the suitability (adhesion).
Undercoat plasters are usually applied at 11mm and most finish coat plasters are applied at 2mm. These thickness' are nominal and determined by deviations in the substrate. Recommendations for the application thickness of Thistle plaster products can be found in our selector guides: ThistlePro Selector Guide, Thistle Essential Selector Guide. The charts also include coverage, setting times, and other application information.
