I start at 8:30am and finish up around 3-4pm. I remove the old caulk from around the tub and chemically clean and etch the enamel. I cover and protect all areas of the bathroom and spray 2 coats of epoxy based primer, then two coats of the acrylic top coat, a non slip surface is built into the paint. If there is a window in the bathroom, I use an exhaust fan to help with the smell of the paint. If there is no window in the room, I have a portable venting machine that I use. The tub is cured to use in 24 hrs, at which point I return to remove that masking paper and recaulk the tub for use. I am the owner operator, and I do all of the work.
