painting new grp garage door - method?

[jamiller]

The door is a brand new wickes plastic door. Can this be painted with a coloured gloss. Should it be abraded/undercoated first? - Then what type of paint. The door seems a little flexible to retain paint without cracks appearing!!

Im not sure but I think GRP plastic is the same as the stuff they use on rainwater pipes..

If it is the you may get away with giving a once oer with fine wire wool to get a key and then two coats of gloss

Might also be an idea to contact the manufacturer

thanks to both - beginning to sound not such a bright idea - but I will ask !!

Just been looking at buying a GRP front door. Wasn't bothered by any of the standard colours so was looking at a company that will spray it any colour you like.
However the advice I was given was don't bother - it will chip and flake off and look rubbish in next to no time. So, I'm back to a standard green front door.

That said they manage to get paint to stick to GRP bodied cars, so there must be some magic technique!

The magic is that its 2 pack paint.

In other words, the paint is mixed with an hardner then sprayed, It is then baked in an oven for about 40 mins to harden it off at around 70 degrees centigrade.

Was always good working in the booths in winter when it was cold but not much fun in the hight of summer

Could be a bit risky baking a plastic door though

Could also be a bit tricky getting it in our oven !! Ta for input.

You can quite safely bake plastics at that temp. Think about the plastic mirror covers or bumbers on cars.

Its the only certain way i can think of for ensuring the paint will stay on. If i were still in the trade i would have painted it for you for a few quid

Maybe worth asking around you local bodyshop on a Saturday morning when the boss is off Thats when we used to make our beer money for the evenings entertainment

Painted a plastic, double , garage door (panel type) in September 2001 - in full sun, with Dulux Once Gloss after a sugar soap and wet and dry down.
Looks like it was sprayed - Fabulous finish....it's still good today.

I wouldn't attempt it unless it was in the sun.

I bet you loved those Robins you used to spray

A lot of boats are GRP, but i think the colour is in the making, those that i have seen painted up, seem to get a bit tatty after a few years,but that could be simply that they are using the wrong paint/ method, would'nt do no harm to phone/ call at a marina if you know where there is one.

I used (after prep) two coats of solvent based gloss.. (thinned a little) still sound six yrs later when I went back to do the outside again.
