    There is a waterproofing sealer called Flex Seal you can get at diy stores and Amazon. See below for a list of their products and if anything will work for you:

    Hello Barry,

    There is a Black Roof sealer called "Roofix" Normally put on the outside and spread over to form a waterproof seal. It is rather gloopy! Otherwise use a Waterproof Sealer used for around the bath. If you want to decorate it, then use lightweight ceiling Cladding. You could stick it to the aluminium with "No more Nails". Hope that helps!

  • I would check with the manufacturer of the the screen structure.

    Like most types of metal surfaces, sheet aluminum is hard, slick and nonporous. This makes it highly resistant to paint adhesion. ... If you want to paint sheet aluminum, you'll need to use a special kind of primer to rough up the surface or you will end up with a finish that will flake and peel rather quickly. Choose acrylic or latex paint formulated for use on metal (and if you're painting an outdoor item like aluminum patio furniture, don't forget to pick a paint labeled “exterior grade”).

    A good quality latex paint will work fine. If the patio ceiling was factory painted, then you will need to clean really well, then you need to sand the surface to help create a bond to the original finish. Clean that well and prime and paint according to the paint manufactures suggestions depending upon the brand you choose. You may want to spray this ceiling also. You can rent a machine for a few dollars that will help make the finish really smooth. It is also much faster to apply if there are lots of groves or gaps in the panels. However spraying does take a bit more work in getting the area protected from over spray.

    I think I would use an epoxy marine paint that will hold up to a moist environment. I get it in the quart size at True Value, its Rustoleum. I used it on my back door when I put in the electronic cat door and had to take off the storm door..... stuff wears like iron. I used the stuff whenever its something to be used outside, works great for me.

  • You’ll need an oil based paint to adhere and protect the metal.

    Hi Barry, you will want to use a high gloss alkyd because it's very resistant to humidity and oil and is very durable

    We used the aluminum sealant that people put on mobile home roofs. It is messy and I'm unsure how you would do it to a ceiling that is in place. Your best bet would be to put some foam board insulation to reduce sweating.

    Hello. Using a high-quality exterior paint that will work on metal would be an option. Your local paint store may be able to guide you to the best choice for your area.

    A good bathroom paint may work, but if you are trying to seal to stop water from coming in, then the sealing must be done on the outside.
