Can I paint Trex?
by

I have a deck that is made out of the original Trex (about 18 years old). It's not the really nice finish that they have now. It is much too expensive to tear up and replace, so I am wondering if it will take paint, what kind, and will it last? I have another deck that is made of pressure treated wood and I have to paint that every other year!!! Ugh!

Contact the manufacturer, you may be able to sand it down to the original color if it has faded
Make a solution of one part bleach to three parts water and apply it liberally to the surface of the deck, as well as to any steps, railing or benches that are part of it. Wait 20 minutes, then scrub the surface with a long-handled brush. Rinse off the solution and any mildew residue.
Next, remove the gloss on the composite by lightly sanding all the surfaces with very fine #220 sandpaper. If the deck material is textured, sand in the same direction as the wood grain, not across it.
Remove dirt and dust from all the surfaces by washing them with a household detergent solution or a commercial cleaner made for this purpose. Again, rinse thoroughly.
If you intend to paint your composite deck, first prime it with a quality exterior latex stain-blocking primer recommended for use on plastic materials. You should not prime if you intend to apply a deck stain.
Complete the job by applying a top quality latex floor and deck paint in a satin or semi-gloss finish (higher gloss levels have better mildew resistance and are easier to clean). If you didn’t prime the surfaces, you can apply a quality acrylic latex solid color deck stain recommended for use on composite decking.
perhaps this can help
