Extratime is a chemical additive for use with finishing plasters. The additive slows the curing process of the plaster by slowing the chemical crystal formation that causes the gypsum plaster to set or harden. Extratime is recommended for moderate lenthening of finishing plaster setting times. Extratime will lengthen the setting time by 30-60 minutes depending on the ambient temperature, relative humidity of the environment and the surface being plastered. 

• Extratime can be used with all finishing plasters.
• It helps make plastering easier especially when working on large areas or in hot weather. It simply takes the pressure off.
• Extend plaster setting times by up to 60mins
• Ideal for plastering larger areas.
• 1 sachet for every 25Kg of plaster​​
