Blushing Creates a Cloudy Finish
How To Get Dark Cabinet Colors? Use a Dye and Wipe Stain.

Blushing Creates a Cloudy FinishWe only had a hand full of 90 degree days here in Vancouver, WA this year. Now, with summer coming to a close and the daytime and night time temperatures going down again, we should consider making changes to the chemistry of our coatings and lacquers in response to the weather.

For instance, during those really hot summer days, we needed retarders and flow enhancers. Still, I’d hold off on putting those away for a few more weeks if I were you. Stay tuned and I’ll tell you why.

This is the time of year when I occasionally hear about blushing. Blushing will happen on those warm Fall days when the temperature is still up but it rains or is damp. The heat of the air makes the solvents in your lacquer flash off faster. The moisture in the air is attracted to that cool lacquered surface and all of a sudden you have a cloudy finish. That’s called blushing and its only solution, in most cases, is sanding off the lacquer and starting over because the moisture goes right down into the coating.

Solvent based spray people, keep that retarder handy and remember to add some on days like I mentioned above. Drizzle is predicted for this coming weekend in Vancouver. Perfect weather for blushing!

Until next time…spray on!
