Painting a metal Garage Door

[Hemsby]

Hi,

Recently moved and I have finished re furbishing my bungalow but now need to tackle the exterior of the neglected garage. I have replaced the rotten timbers at the bottom of the door frame by splicing in some new timber. But the door is looking very sorry for itself.

The existing paint is cracked & peeling, I will remove all the paint back to the bare surface which is galvanised steel or steel Zinc plated.

I know the door it is at least 25 years old. The advice I would like is once the old paint is removed should the surface be treated as new Gal/Zinc and be treated with something like a mordant solution or after all this time go straight to the metal primer.

regards

Keith

I used Hammerite Garage Door Metal Paint straight onto the galvanising.
Lasted 3yrs now and still going strong.

Thank you,

Problem with hammerite, is that once you've used it on a surface, its very difficult to use any other product over it.

If the galvanised surface is shiny, t-wash the surface until it turns black. Then prime, undercoat and top coat with a decent exterior gloss or satin finish.

I removed the ****** up and over metal door and replaced it with offset side hung timber doors. Much more practical and only cost about £200 in materials, including 4x3 mahogany jambs and top rail.

What timber did you use for the doors?

4x2 frames with 3/4" marine ply outer skin, 50mm Celotex insulation and 1/2" OSB2 inner skin. All treated with Cuprinol Garden Shades Ash Black.

I served a 7 year apprenticeship, obtained my City & Guilds, and spent the rest of my working life as a professional painter & decorator, so at last I am able to offer some advice in this forum.

I would use zinc oxide paint as the base coat on the garage door as it is an anticorrosive coating which is particularly effective on galvanised surfaces. Zinc oxide paint also retain adherence and flexibility for many years.

Best solution, especially for garage workshops; in Cedar. even better, but when SWMBO is paying for the door, she decides what kind of door it will be. Hence one powder-coated, maintenance free, up and over. The only positive is the secure four-way locking system. (Plus a ruddy great Volvo parked right up against it! ) As I think you know MM!
