Been spraying Glamor II for 10 years with minimal problems. Have always had ink come off a little with light abrasion but it has gotten worse, much worse.
A professional sprayer for my cabinetry business with the best Binks equipment for 25 years so I don't think it is application issues.
I have to put a soft velour blanket over my carpet covered wrapping area or it will rub through the finish to the ink so easily just attaching the hanging wire.
The mixture is by the book, typically 20 to 25% water to get the viscosity just right for spraying. Breathing Color says do not exceed 30%
The only factor I can think it may be is my room temperature in the shop is 60-64. I have had the same issue even in the summer when the temps are 75 to 85.
I talked to Breathing Color about 5 years ago and we went over just about anything it could be. The final response was pretty much if you are not happy with it to try Timeless.
I spray a light coat of gloss, let flash dry for 15 minutes then put the final coat on a little heavier. Even adding a third coat is no better. A light scratch with a fingernail and you go right through the ink.
Plan to call BC again Monday. Something is wrong.
