Hey folks. Remember way back when I posted that we were trying to figure out whether to try and rehab the old HVAC vents or replace with new ones?
Well, we decided we’d try and rehab the old ones. Unfortunately, we didn’t make this decision until after we’d already thrown out a couple of the old vents (dumb, dumb, dumb!). But we’ll make do with the ones we’ve got.
Stripping the paint and grime off the old ones turned out to (mostly) be a lot easier than I thought it was going to be. Don’t get me wrong, it was still terrible, but not too terrible. I filled a baking sheet with about 1/2 inch of paint stripper and just set the vent in it face-down and let it set for 10 minutes.
When I would just lift the vent out of the stripper, 90% of the paint would just fall right off.
At this point, we figured out that the best next step was to use a high-powered spray attachment on a hose (nothing fancy, just a garden nozzle set to deliver a blazing laser of water) to blast off all the stuff the stripper had loosened up.
After that, there was usually one or two more rounds of spot-applying the stripper to a few remaining areas, using a utility knife to scrape in a few problem areas, and just a tad bit more general scrubbing to get them clean. But the key was always going back to the water laser.
Here’s what the vents looked like before we spray painted them the first time (more on that later). One mistake we made was that after spraying them with the water, I guess we didn’t dry them quickly enough, and we started getting a bit of rust.
OK, this is where I started getting mad and stopped taking pictures. We applied a coat of primer to all the vents, and everything was looking great. Then we added the first coat of spray paint, and it looked terrible. The paint was bubbling all over the place. I’m not sure why. The bubbling paint looked just like the old paint did after we had applied the paint stripper, so my best guess is that there was some lingering stripper residue on all the vents that was sabotaging our efforts to spruce them up.
Long story short, after all that paint dried (and looked terrible), I ended up using a palm sander to sand all the paint off all the smooth surfaces. This turned out to be relatively easy, actually, and it sanded the rust off too, so ultimately I guess it was a blessing in disguise.
Anyway, after all the hard work and scrubbing (and cursing), here’s what we finally ended up with.
Overall, I think they turned out pretty well. What do you think?
