Product description
Extratime Plaster Retarder 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 lengthening of finishing plaster setting times. Extratime will lengthen the setting time by 30-60 minutes depending on the ambient temperature and relative humidity of the environment. Extratime is suitable for use with the following finishing plasters: Multi Finish Plaster, Finishing Plaster, Board Finishing Plaster

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
