Re: Painting exterior metal

A butyl or silane caulk would be nice. What color did you want?

Re: Painting exterior metal

I'm painting the stairs glossy black. Is the butyl you recommend a tape I'm seeing on the Home Depot web site?
It sounds neat and easy. Butyl good for black, or silane caulk better. I guess one takes paint better or you wouldn't have asked about the color. And thank you for your response.

The trick will be finding the caulk in the color you want

Perhaps another Pro will know a source for the black caulk you need. Generally if its waterproof, its not paintable.

How about GE Silicone ii paintable silicone?

A good caulking for this job is "Lexel" which is clear, durable, very elastic, very adhesive, and paintable. Be careful in applying it as it is very sticky and tends to smear- this also prohibits the usual 'tooling' afterwards with a fingertip so make it right as you apply it.

Is there a correct order of the priming, painting and lexel caulking? Between leaving the metel unprotected after scraping old paint and rust, and waiting a week to a month the lexel advises before painting, and wanting to make sure the lexel adheres, I was planning on priming first, lexel, lastly top coat. Ok?

Sounds good under the circumstances.

You've got it right, though I have successfully painted Lexel a week later if it seems solidified (it does dry slowly if it's thick). Sorry for not getting back sooner, it's working season here!

Re: Painting exterior metal

Ugg...The rustoleum top coat paint is starting to peel on a couple of the steps and a riser. Couple of chips on the rails, but that's not the big issue. I don't know if the peel is contained or will spead and I want to make sure it's under control. The primer I used was the rustoleum clean metal primer which rustoleum recommends to use with the top coat, seems to be sticking fine. I contacted rustoleum and they said the paint was not intended for foot traffic but since there is minimum foot traffic they did feel it should have been ok.
Rustoleums recommended scuff sanding and applying more top coats.

Should I switch paints brands? Then I would reprime and paint?

If I do continue with rustoleum, I guess I wouldn't need to reprime. But then between layers of top coat, how many days do I have before I have to scuff sand. Could that be what I did wrong last year, waited too long between the primer and topcoats, waiting for the lexel to dry? Or maybe I didn't apply the second coat of topcoat soon enough...
Thank you..
