Re: Acrylic Paint on Alluminum

If no one is sure about my question above. Does someone know a paintshop who does powder coating somewhere in makati or paranaque?

Thanks.

Re: Acrylic Paint on Alluminum

It can bond if you use a metal etching solution. Its some sort of acid that basically takes out the "smoothness" of the surface for the primer.

Boysen has such but i never found it in stores. its in their website though.

so if i'll be using etching solution, i don't need to sandpaper it?

after painting it with acrylic paint, do i still need to spray a compatible clear coat on it?

the brand that i'm planning to buy is rj london. i don't know someone who has tried this so i'm still thinking it over.

Re: Acrylic Paint on Alluminum

boysen suggests the use of the water based primer called PRIMEGUARD for non-ferrous metals like aluminum, galvanized and stainless steel. check their website on its use. it comes in a 1 gal can. i got mine from boysen at d. tuazon for P510 last week. dealers do not usually stock and is on an order basis. used it on stainless, after buffing it with a brass cup brush on a drill chuck, and so far it looks good.

i'm not sure if i understand this correctly. does is mean that the primer served like a clear coating and protective paint on the stainless thingy that you buff?

if that's the case, i could probably do the same thing on my alluminum thingy. buff it and spray paint it with that primer.

please correct me if i'm wrong.

thanks.

Re: Acrylic Paint on Alluminum

The key to a good paint finish is surface preparation.
1. Use metal etching solution- rust converters like Turco/Cord/Turbo will work
2. Rinse and sand
3. Coat with primer- since you are using acrylic paint, use acrylic primer. It's available even in aerosol cans. Boysen's PRIMEGUARD is a water based acrylic primer. Problem with water based paint is it doesn't have a smooth finish and it is very hard to spray.
4. Paint

will the metal etching solution remove existing paint from the alluminum or a paint stripper is still needed?

If there is an old paint already, and that old paint is bonded well, then you can skip the etching and priming. Just sand it lightly then paint over it.

But if you want to remove the old paint for some reason, then yes, strip it completely and start all over again.

i did an experimental painting last weekend using an acrylic epoxy spray paint. unfortunately, there are some etchings before that cannot be read after painting it because these etchings have been painted before and i just cannot remove it by sanding it. i thought i did well but then it's just the opposite.

will etching solutions strip the existin paint or do i still need i paint stripper especially on the etchings with paint?

thanks

Yes you will need paint stripper to do the job.
To prevent having too much paint on the engravings and making it unreadable, make sure to spray several thin coats than just a few thick coats.

thanks. that's what i'm planning to do.

i don't know who did the first painting but it was so thick that the engravings were almost covered.

Re: Acrylic Paint on Alluminum

Just one additional question:

Is Acrylic Lacquer paint compatible with Acrylic Epoxy paint?

I have already painted the alluminum with Acrylic Epoxy spray paint. Now I'm told that it would be better to spray clear coat for additional protection.

I still have a clear Acrylic Lacquer spray paint and I just wanted to make sure that it is compatible with the Acrylic Epoxy paint befor I start spraying it. Otherwise, I have to buy a clear Acrylic Epoxy spray paint. That would be an additional cost that I would like to avoid if possible. 🙂
