What is the minimum temperature for Gypsum Products?
Thistle plasters should only be applied to backgrounds where the minimum temperature will remain at 2°C or above until dry (except ThistlePro DuraFinish which should remain at 5°C or above until dry.) Dry, bagged plaster isn't affected by low temperatures.
All Gypsum based products are not suitable for use onto frozen backgrounds, and so products such as SoundCoat Plus or DriWall Adhesive should also remain at 2°C or above until dry.
In all instances, allowance should be made for longer drying and setting times.
For further guidance, refer to the ‘Effect of temperature’ section of the relevant Product Data Sheet, here.
