Painting Aluminium Windows in High Rise Apartments

Sanding the window frame surface is best done by hand. The coarseness of the sand paper will depend on the substrate and condition. It is recommended that 24 grit be used on non chalking powder coated surfaces and 60 - 80 grit on anodized surfaces. After sanding, the surface needs to be blown off with air to remove dust and dirt. It is also best that prior to painting, further solvent wash must be carried out.

Masking up and over spray protection of adjacent finished surfaces is imperative on a high rise apartment environmental setting. First, mask up the rubbers that are holding the glass in place in each window frame, and cover the glass using a paper or plastic film ellipsometry. Use film to protect the surrounds of each window from the edge of the window frame outwards, along each side by about 500mm.

Use plastic drop sheets and canvas drop sheets to protect the floors. Isolate the area that painting area by putting a plastic wall between the ceiling and floor.

Paint application Using a two pac three coat system and a HVLP spray gun. Apply a light primer sealer coat to the substrate. A single pac etch primer is recommended followed by two top coats of a poly urethane (Acrathane). To achieve desired film thickness ellipsometry, it's best to apply four light coats instead of two top coats.

Lastly, you should look into overhauling the mechanic components of each window and sliding door. It's best to replace all rollers, the weather felts in the frames, and any broken springs causing the window latches to fall down to the bottom of each window.
