Hello everyone Im knew on here an reasonably knew to the trade been getting a bit of work lately just seems that the multi finish keeps going off quicker an quicker on me dont mind but not massive areas that im doing any ideas what I might be doing that could be making it set so fast please dont tell me moving to slow haha some is going off less than an hour :RpS_scared:
Here's a list of factors that affect the working time:
1) Heat: warm environments => less working time.
2) Plaster that has been mixed too thick: less water than normal => less working time.
3) Use of dirty water containing gypsum: the already reacted gypsum will send the mix off more quickly.
4) Suction: high suction => less working time.
5) Through drafts: more drafts => less working time.
6) Over mixing: extended mixing => less working time.
7) Expired plaster: use with caution.
All of the factors are straight forward to control. However 4) is most likely the cause of your problems. Since you are relatively new to plastering, save yourself the headache and use Gyprime for high suction backgrounds or Bond-it for smooth low suction backgrounds
In addition, if your first coat of plaster is too thin, there is less water available to quench the thirst of the background and the plaster will hang for less time
