   I've sprayed it with Krylon before, but I've never brushed it.  Just put insulation and duct tape on it, or tell her that paint will cause leaks.  Just don't let her talk to any plumbers,or you're in deep doo-doo.

   Clean the pipes with soap and water, or 409, etc. Then sand lightly with 120 grit and blow off the dust, or remove it with damp rags/paper towels. Latex will stick directly to the PVC, or you can prime with Kilz first for a better bite.

   PVC roof vents are supposed to be painted for UV protection, so it gets done all the time.

   Really?

   I don't think I have ever seen one painted, but it makes sense. Plumbing pvc will get brittle from UV exposure and roof vent is certinly exposed.

   Now I have to go paint my vent stacks....

   Painting PVC stacks happens all the time, but not on all the jobs! It can also help the house aethetically if the vents show from the street.ABS does not have as great of a need to be painted. The carbon black in the ABS formulation protects it somewhat from the UV. I paint them anyway, to match the roof.Bill

   I think probably on over half the custom homes the vent stacks are painted. They are ugly and stand out so they get painted to a colour that makes them blend to the roof a bit.

   Bill is right, latex stick fairly well to PVC. Just wipe it down with paint thinner to remove any greasy spots. Paint it white because any dark color will highlight any scratching of the paint.

   Washing and sanding is too much work but as in all painting, it's usually necessary. Part of the problem is that not everything on the PVC is water or solvent soluble, so using one won't get rid of all of the dirt. I have used acetone and lacquer thinner before painting and after 6 or 7 years, what I painted has no bare PVC at all and it's all outdoor stuff.

   Clear primer is not always an option---- UPC clearly states that you have to use "purple primer"

   When doing swimming pool mechanical rooms I always use masking tape just shy of where the end of the fitting cup will slide onto the pipe.

   I like the way it ends up looking---- white pipe & fittings with a blue glue ring about 1/4" wide next to the fitting & a purple ring 1/4" wide just outside of that.I fear no man & only one GOD. Me

   I had no idea that purple primer was required. Is that so the inspector can confirm its use?

   For the most part yes, sometimes inspectors won't admit to that reason & will give the " it's in the code book" response.I fear no man & only one GOD. Me

   JohnD1:

   The composite house trim AZEK is PVC.  If you go to their website they explain the procedure for painting their product and make paint recommendations.

   Like another poster said, the Azek site lists some paints that work well on PVC. (Sherman Williams Superpaint, which is vinyl safe, comes to mind). But, expect to create some issues down the road if you ever need to work on the plumbing in the future. I, for one, would be pretty put out if I had to sand down the paint on a waste line to add a fitting!

   I made a curb around our baby changing cushion out of PVC, primed and painted it with a gloss acrylic enamel.  Did quite well for two kids.

   We paint all exposed PVC and sheetmetal vents above the roof with High temp charcoal grill paint. Flat black so we can go straight from the chimney flashing and stove pipe to the solar panel pipe covers, pvc vents, and range hood vents all in one trip to the roof. Never had any problems with lack of prep causing peeling. In the basement I'd just get some white paint and spot up all the primer. I agree it looks messy but the inspectors around here want proof that you primed those pipes.

   another vote for krylon.

    

   have painted the stacks outta the roof coupla times.

   first time was on a first floor reroof where they decided to extend the deck.

    

   big white pipe really stood out ... coupla blasts from a paint can and she disappeared.
