Back to Pretreatment Surface Preparation

Q:  My steel siding is badly faded, as I think it might be 20 years old.  I want to paint over the steel siding.  What is involved in this? 

A:  The most important step to refinishing pre-painted steel is to prep and clean the surface with high pressure washing and a heavy duty detergent designated for good removal of accumulated dirt and oxide.  After cleaning select a good quality acrylic latex topcoat.

I recall a couple of jobs of repainting pre-coated steel, both of which resulted with excellent performances.
