Easy to mix. Iโd certainly recommend using a hand spray bottle to apply it rather than a brush. It seems to rigidise my thermal kiln blanket well and is economical.

This product worked great to hardening my blanket for my forge ... one thing I would say is make sure you don't do half and half it will take forever for it to dry I placed my forge in the oven at 280 for about 2 hrs helped alot . I would do 3 parts solution to 1 part water it will go faster but it makes it harder to come out the spray bottle .
