How do I paint a Garaga garage door?

General information

If you decide to paint your Garaga door yourself, the following instructions outline how to do it. It is important to note that oil-based paint (alkaloid) with a matt or semi-gloss finish does not exist in the market (unless an industrial paint is used).

Therefore, it is recommended that latex paint be used to avoid highlighting imperfections in the metal. Use a brush to contour the raised panel, and a roller (1/2" (10 mm) to provide a nice finish.

If your customers want to paint their front door and/or windows, it is possible to closely reproduce the colour of their Garaga door. See the Sico, National / Laurentide and Benjamin Moore colour codes on the next page.

We have used the Sico, National - Laurentide and Benjamin Moore paint companies, but any good paint company can be used, with the stages remaining the same. Some dealers are equipped with an electronic machine to find the exact colouration. A colour sample will be necessary.

Before painting any Garaga garage doors, we invite you to read the document about the Limited lifetime warranty.

How to repaint a Garaga door:

1. 1. Wash the surface of each panel with phosphate trisodium (Polypred 771-137) to remove grease and residue. Rinse completely with clear water and let it dry.


2. 2. Sand the surface of each panel with sand-paper (grade #220) in order to create an adherence profile. Avoid using steel wool. Clean the panel with a tack cloth or a vacuum.


3. 3. A primer coat is necessary only if the enamel is taken off, if the steel is visible or if there is some rust. In these particular cases, apply a phosphate coat of zinc primer: Sico(Corrostop Light Beige 635-260 or oxide red Sico 635-785), National - Laurentide (Dura-sol 545-062 (8545-91)) or Benjamin Moore primer serie 163. Let it dry a minimum of 16 hours before painting


4. 4. Apply 2 coats of latex paint
