Hi all, thanks for your comments on this.
We do not recommend spray application with Thistle MultiFinish for a number of reasons. When tested, we have seen over shelling off the wall and excessive cracking. We also have concerns that Thistle MultiFinish could clog machine feeds.
That said, we do appreciate the views expressed here, and could be willing to make some site visits to see how the product is being used in spray application.
Your more than welcome to visit our next demonstration and see how the machine performs.
If you can remember, the M100 was specifically designed for use with Multi Finish.
To be honest, I have never come across this issue and am unsure why this would even happen
