I'm gutted.
I rendered a large area in S&C and then used bluegrit.
Thought I'd try Extratime in the multifinish due to the size of the plastering.
The product was in date (expires 2023). Purchased from Travis Perkins. 1 Packet added to 12L of water. Thoroughly mixed before adding to 25kg bag of multifinish. First coat started crazing after an hour. Mixed new lot as above, and applied final coat. Nothing to lose as plastering already looked ruined. Hoped 2nd packet would cover problem however same thing happened during drying overnight. Amazon reviews have a lot of good ones and also a couple of people having similar problem to mine.
I would strongly suggest DIYers don't risk using Extratime due to the risk of ruining your hard work.
