Why not just paint?

The paint on your metal roll-up doors was originally baked on and according to the manufacturer's limited warranty they will not "fade" for years, which does NOT take into account chalking, (which is the biggest problem). There is still good paint under the chalk which can be refinished to look new again.   

Repainting is more expensive than refinishing and will not last as long. Putting more paint over failing paint is not the answer.  Paint that is not baked onto metal will oxidize faster, and may crack, peel, blister, chip and ruin your doors. We do paint but unless absolutely necessary (bare metal showing, peeling, etc.) refinishing is a much better option than adding another layer of paint. 

Exterior metal that is repainted will rarely rival the original baked-on finish in sheen or quality and because of the chemical make-up of paint, exterior metal that has been repainted begins to age almost immediately.  

If your doors are already repainted, you can now seal them with Everbrite Protective Coating preventing moisture and sun damage.

What causes paint failures?

The inability to bake on the paint in the field, improper preparation, moisture penetrating through paint to separate the new paint from the baked on substrate and various other reasons.  

But I know of paint jobs that haven't peeled or cracked.

The main reason for painting is to try and improve the image of the facility. Even though the paint may not crack or peel, repainted surfaces will chalk and fade even faster and to keep the facility looking new, the surfaces will need to be repainted again. Paint over paint over paint will peel and crack. Moisture will penetrate paint, separating the layers and eventually cause paint failure. 

This is an industry wide problem and we all know people who have repainted metal, only to have the paint peel or fade even faster and have cost themselves many thousands of dollars.

 Sadly, the money spent on painting to improve the image of their facility actually added to the problems and subtracted from the bottom line.

Here are some examples of repainted doors and metal buildings. Click on the thumbnail for larger picture. 

To avoid these problems, refinish your metal doors or metal buildings with Everbrite Protective Coating instead of painting over your original finish.  Re-painted doors and metal buildings can be sealed to avoid moisture penetrating and causing these problems.
