Product review (5 stars): Exactly How I Painted Mine
Totally blocked the cold air that always infiltrated my laundry room. I mounted it directly to my outside brick face, had to drill new mounting holes larger to take the masonry screws, no problem. Here is exactly how I painted it, worked great: (1) Clean and de-grease with vinegar solution. I was lazy, so I soaked a medium-sized hand towel with water then just poured some white vinegar on the soaked towel, squeezed it a little to mix, then wiped all the parts down. Liberally rinsed under tapwater and let dry for 24 hours. (2) Hot-glued the parts to arm-length sticks so I could hold them for spray-painting. Heated later to remove, no paint damage from heat. Also masked mating surfaces with 3M Blue or circular paper-plate cutouts, Chinet heavy duty to be exact. (3) Sprayed 3 very light coats of Dupli-Color Adhesion Promoter, 5 minutes apart. See pic attached for exact can of Dupli-Color I used. (4) Waited another 5 minutes then sprayed 4 very light coats of Krylon Fusion White Gloss, 5 minutes apart. See pic for exact can of Krylon I used. All this spraying was done at 50-55 degrees F, outside, slight wind. (5) Let dry/cure inside for 8 days. Then removed hot-glued sticks and masking and installed.
