Painting aluminum to be installed in concrete

A professional exterior painting expert will use a spray application for a smooth, factory like finish. Plus, if you happen to change your mind about the color before two decades have passed, Hardie Plank requires less repair and prep work than wood siding which will need scraped and sanded, or even replaced in some areas. Even then, a professional paint expert will offer a color consultation to make sure you get the exact color you want.

Wipe the dust off with a tack cloth, then buff it again with grit sandpaper. If the or grit sandpaper created deep gouges, follow-up with and grit sandpaper before moving on to grit. Sanding the metal will help give the primer something to stick to. Rinse the surface again with warm water and degreaser.

Fill your tub or bucket again with warm water, then add a few pumps of a degreasing cleaner. Rinse the metal off with this solution, then rinse it again using plain water. Allow the metal to air-dry before moving on. Alternatively, you can wipe the metal down with a tack cloth. Part 2. Purchase a can of self-etching paint primer. Do not use regular paint primer, even if it is labeled "for metal. Purchase a can of "self-etching primer" from a home improvement store or an auto specialty store, and use that instead.

Cover any areas that you don't want painted with masking tape. If you need to mask off a large area, cover it with paper or plastic sheeting first, then secure the edges with masking tape. Find a well-ventilated area to work in. While you can brush paint onto aluminum, you have to spray the primer on.

The aerosol cans that paints and primers come in release fumes, which can cause headaches and lightheadedness. Outside would be the best option, but if you can't work there, choose a large room with good ventilation and open windows. A respirator mask is a must. Do not paint if it is raining or humid outside, as this can affect the curing process. Spray an even coat of self-etching primer onto the aluminum. Shake the can for about 30 to 60 seconds first, then hold it about 8 inches 20 cm from the surface.

Spray on a light, even coat using overlapping strokes. You can spray side-to-side or up-and-down. Overlap each stroke ever so slightly to ensure that you are covering the surface evenly. If your can has a different set of application instructions, you should follow those instead.

If you are working with a multi-sided object, let the first side dry to the touch before priming the other sides. Let the primer dry for 15 minutes before adding a second coat. Check the can again to find out exactly how long you should wait before applying a second coat. Most primers will have a "between coats" drying time and a curing time. Refer to the "between coats" time for this.

In most cases, you'll have to wait between 5 and 15 minutes. Add 2 to 3 more coats, then wait about 1 hour for the primer to cure. Again, check your can to find out exactly how many coats of primer you should use and how long you should wait for it to cure. In most cases, you'll need about 3 to 4 coats of primer and wait about 1 hour for it to cure. If you don't wait long enough, the paint and primer may peel. Double-check the instructions on the can for more specific curing times.

Remember to apply light coats of primer. This will help it cure properly. If you slap on a thick coat, the primer may go tacky or just peel off. Buff away imperfections with grit sandpaper, if needed. Once the primer has cured, take a close look at it. If you like the finish, you are ready to move on. If it looks rough, pitted, or drippy, lightly buff the surface with grit sandpaper. Double-check the masking tape after this.

If the edges look frayed, peel it off and lay down new strips. Part 3. When I see aluminum railings, it seems they are always bolted down with stainless steel anchor bolts. Is there any corrosion or rusting of metal when bolting a foot railings of a metal gazebo directly to the cement? If there is, what can be used to separate the two components? Hi Lee. It might depend a bit on whether the gazebo feet are aluminum or steel, and what surface treatment they have received, but I don't see a serious problem.

What will cause rapid rust, though, is if water is retained between the foot and the concrete. Make sure this isn't a low spot, and is preferably a high spot. Good luck. Dear Sirs: I am involved in the design of T5 aluminum parts that get embedded in concrete. Is Alodine finish a suitable anti-corrosive barrier for the aluminum parts for this condition?

Can you direct me to a site with the Alodine on aluminum anti-corrosive properties? Thank you. Hi Steve. Alodine is a Henkel Corporation trade name for their line of chromate conversion coatings for aluminum.

Hopefully they can give you specifics; otherwise search for "chromate conversion coating of aluminum", "chem-film" a term used mainly in the USA , or Mil-DTL [link is to free spec at Defense Logistics Agency, dla.
