Setting too quickly
by Peter long
I use good quality plaster and also check the date on the bag but every time I do some plastering it goes off within 10 minutes or so the consistency is ok cos it does not slide off when. I put trowel to hawk please could you help me
If you use a new, in date bag of 'Thistle Multi-Finish' and mix with clean tap water - details at http://www.diyplastering.co.uk/plasteringfinish.html
then you will have a lot longer than 10 minutes.
