Q: I have a new pre-primed steel door I plan on painting. What is the best way to apply the paint?
A: For steel doors, we recommend 100-percent acrylic latex exterior paint so it can expand and contract with the extreme heat that metal doors will retain. Using a sprayer will achieve the best finish, and a high-quality acrylic latex paint will be formulated with levelers to even out the finish and help it lay down without adding any thinning agents. In lieu of a sprayer, a 4-in. foam roller will also do the job without leaving bristle marks from a paint brush.
