Lisa: I’ll do whatever it takes.
Bart: Then welcome to the nether regions of the soul.
The green paint on our porch floor is flaking off. Something has to be done! We really want to go for the natural wood look, but that means stripping the paint.
Stripping the areas where the paint is flaking off is not a problem, but other parts of the floor are not flaky. In fact, they’re so not flaky that we’re thinking about abandoning the natural wood idea.
At this point, we have tried a few different paint stripping methods without success. The green, top layer comes off pretty easily. Under the green paint there’s a gray layer, which is extremely well-adhered to the floor boards.
Apart from the porch floor, every wooden surface in our basement is painted with the same gray. It’s also one of the layers on the window frames. It appears the original owner was in possession of a consignment of paint that might, if it hadn’t been attached to our house, have seen action in the Pacific Theater of WWII. Suffice it to say, it’s very good at being paint.
As I said, we have tried a few different paint removal methods. Here’s the story so far:
This was the first idea. Looking at the flaking paint, it occurred to me that I could strip the whole thing by hand. So, I got to work. Well, the flaky bits do come off quite easily. Unfortunately, the non-flaky bits don’t come off at all.
One day, Stacey surprised me with this Craigslist purchase.
This kind of tool was new to me. Seemed like a good idea though. So, I set about the porch floor with it. It does quite well, but doesn’t get all the paint off.
I think the problem is that the floor is not perfectly flat. The tool has a very small cutting depth, less than 0.3 mm. It is held to that depth by the base of the tool, so it removes paint from the high points, but can’t reach into the low bits. I could increase the depth of the cut, but that would mean taking out big chunks of wood from the high points of the floor.
Chemical Paint Removers
Mechanical methods were really falling down on the job. Time for chemistry!
Since we have cats and a sense of environmental responsibility, we try to only use chemicals that are harmful to neither. Or, at least, that’s how we begin. We tried each of the chemical methods on both mechanically ‘stripped’ and untreated areas.
Mild Citrus Paint Remover
We began with a mild citrus paint remover.
After being left on for 24 hours, the citrus stripper was pretty good at taking off the green paint, but didn’t touch the gray.
Slightly Caustic Paint Remover
We also tried a slightly more cat and environment unfriendly stripper.
Again, after 24 hours, the green came off pretty well. Zinsser Magic Strip also took off some of the gray paint, but not enough to call this test a success.
Extremely Caustic Paint Remover
So, after the failure of the cat and environment friendly options, we went for the nuclear option.
The Klean-Strip Stripper easily removed the green paint. But, even after two applications, it didn’t take off all the gray paint. We also tried Klean-Strip Stripper on a Metabo-stripped area.
But that really wasn’t any better at removing the gray.
Our options are dwindling. On the chemical front, Christine at Little House on the Corner recommended Peel Away (she used it successfully on a detailed fireplace), so we will give that a try as soon as we can pick it up. But if that doesn’t work, we are already stalking ebay for one of these:
That is an infrared paint remover and its various included tools. There are a few different tools like this on the market (this one is the “Silent Paint Remover”), and they use an infrared lamp to heat paint hot enough to quit sticking, but not so hot that it emits lead vapour. It’s all upside except for the price (ergo ebay).
If all else fails, or we just decide that it’s way more work than it needs to be, we may just repaint the whole floor, assuming we can achieve some level of smoothness. But that option is a few d’ohs away yet. (Update: further d’ohs on this topic here!)
As always, if you have any suggestions that might help us take off stubborn paint, we would be more than grateful to hear them.
