Пошаговое руководство по покраске алюминиевой двери

Giving your aluminum door a fresh new look is easier than you might think. Just follow these steps carefully for a clean, lasting finish.

1. Clean the Door Thoroughly

Start with a deep clean using soapy water или TSP to remove dirt, grease, and grime. For any rust spots or paint splashes, use a Scotch-Brite pad or light sandpaper. Rinse well and let the surface dry completely—this step is key to good paint adhesion.

2. Remove or Mask Hardware and Glass

Unscrew ручки, locks, and mail slots if possible. Cover any glass or wall edges with painter’s tape and newspaper. A clever trick? Slip a latex glove over the handle and tape it off—it gives clean paint edges without the hassle.

3. Sand and Prep the Surface

If the door has a glossy или powder-coated finish, gently sand it with fine-grit sandpaper to help the primer grip. Don’t overdo it—just enough to dull the sheen. Wipe away dust with a clean cloth.

4. Apply Metal Primer

Use a quality etching primer или DTM (direct-to-metal) primer for a strong bond. Spray or brush it on in thin, even coats. One or two coats usually do the trick. Be patient and allow each coat to fully dry.

5. Paint the Door

Now for the fun part—painting! Choose акрил или epoxy-based paint for aluminum surfaces. Apply with a foam roller или spray can in multiple thin layers. If spraying, use short bursts to prevent drips and get a smooth, even finish.

6. Let It Dry & Apply Additional Coats

Wait at least 2–6 hours between coats or follow the paint manufacturer’s instructions. Apply 2–3 coats for best coverage. Avoid thick coats—they can lead to runs and uneven gloss.

7. Optional: Apply Clear Protective Sealant

Want extra protection from УФ-лучи, moisture, and scratches? A clear sealant designed for metal surfaces will lock in your color and keep it looking fresh longer.

8. Unmask and Reinstall Hardware

Remove masking tape while the paint is still slightly tacky—this gives cleaner edges. Once the paint is fully cured (12–24 hours), reinstall all hardware and enjoy your door’s fresh new look!
