Need to add... Be sure to prime it first with a good latex primer.Markw84.....I am getting ready to build a closed chamber. What brand of food counter top paint did you use? Also, did you paint the entire inide of the chamber? Three coats?..................thanks
So for more detail...
I paint the entire enclosure in and out with a good latex primer.
I then use a paintable caulking and caulk all the inside edges / corners.
Then two coats of Rustolem countertop paint on the inside.
I do fill all gaps and blemishes on the outside with a wood filler and sand smooth. (because I am anal and love things looking perfect!)
That is before sealing the outside.
Then paint the outside with two coats of a good latex gloss enamel.
Hope that helps.
