How to paint an up and over Steel Canopy garage door

When over painting an up and over garage door you need to prepare the surface as you would any other surface.

Wash off any dirt and grit, then abrade the surface with sandpaper, I tend to use 80-grit for this. Key the surface all over including the bottom and sides.

Now you can dust off the door and undercoat with the appropriate colour undercoat.
I normally start by painting the two edges, but not the bottom of the door. Be careful when painting the edges of the door not to get any on the frame if the door is a different colour, lift the door up about half way, you can now paint the edges.
Next, if your door has horizontal sections start at the top working down, if the door has vertical sections start from one side working across, if the door has panels do these first and then paint the rest of the door.

When I paint either a door with horizontal or vertical sections I do the same thing, I paint the groove first, then the panel, then paint the next groove and then the panel and so on, then with the last panel I paint the bottom of the door.

When the undercoat is dry do the same procedure as before but with your chosen topcoat.

When you topcoat, work fast, that way the paint flows nicely and you can put a good amount on. As you paint the door lift it up as you go, it’s far easier; you don’t have to bend down and the paint wont run!

Finally, when you’re done lift the door all the way up, this serves two purposes, firstly the paint won’t run and will flow well, and secondly it stops insects, dust and dirt blowing over the wet paint on the door as most of it is in the garage.
Be aware of rain though, if the door is left up and it rains the rain will lay on the door and ruin your paint.
