Roger and I are continuing to work on removing paint from two internal granite stonewalls. I should amend that statement: We are continuing to explore ways in which to remove paint from these walls. This is no easy task and has introduced delays to all other aspects of this renovation project.
The floorboards are sanded and ready to be installed into place, but are sitting in the barn. The ceiling, wiring and lighting are all on hold. We can do nothing more until we get the paint from the walls. Then, we will be able to power ahead with finishing this room and beginning the next. We are now all too familiar with how one little snag can hold up our projects for weeks, if not months.
Painting granite stones is a decision that should not be approached lightly as its removal is no simple matter. We have tried scrapers, sandpaper, wire brushes attached to either our hands or to drills and all to little effect. I read about Soda Blasting, which is a dry and environmentally friendly approach to clearing the walls using baking soda crystals moving at 600 miles per hour. Sounds great and hours of YouTube viewing told us that we could build our own blasting gun, buy baking soda in huge tubs, and we would have success. More viewing indicated success was the domain of gear-heads who wish to remove gunk from vintage car parts. Our internal, bumpy, porous granite wall requires another solution.
While we both work hard, it’s safe to say, our general approach to projects plays to our strengths. I like the planning, dreaming, and logistics. Roger is the researcher. Sam likes walks. I could fill these posts with Roger’s efforts which not only save us money, but help us to accomplish projects without having to re-do them. Sure, we stumble sometimes, but mostly, we make progress in small, but fairly precise steps.
Not discouraged, more investigation indicated we could purchase equipment to do our own “blasting”, but being on a generator made this a troublesome proposition. A steep, downward slope of money-spending, mess-making, and no-guarantee of success awaited.
What to do next?
We invited someone out to have a look. “Oh yes, I can do that. Sure, we bring our own generator. Yep, we’ll build a containment wall to minimize the mess. No, you can’t do it with soda, you’d need to use….” And it was at this point that I checked out seeing nothing but huge costs and huge mess. Still, it was an option.
Returning home from a day of working at the local cheese shop, I found Roger in the corner of the room wearing a headlamp, rain gear and rubber gloves, examining the wall. When I asked what he was doing, he replied, “I’ve been conducting a bit of an experiment today. Here, let me show you.”
Roger had placed on the wall two test patches of a peel away paint stripper known to remove paint from stones. One patch used a non-toxic paste, which was covered with the peel away paper. The other spot had a caustic paste. I didn’t like the idea of this one, as we are looking to remove paint from about 20 square metres of wall. That’s a lot of potential skin damage.
While I listened to Roger’s explanation of the pros and cons of these two paint strippers, I noticed another patch on the wall uncovered by peel away paper. In this area, Roger had put porridge.
I love porridge. It sets the day off to a good start. Low calorie and high in protein, this superfood may be the key to living longer according to a study by Harvard University. Who knew, it could also strip paint from walls? As I stood there looking at the three patches, I wondered if my stomach lining was being affected having had the cooked oats earlier in the day.
“How would porridge work?” I wondered aloud. “Not certain, but it seemed cheap and easy and worth a try.” was Roger’s reply. I retorted “My brother told me that serpentine is what you use to get paint off a boa constrictor.” and then went off to do my own bit of research where I stumbled upon not just a single comment, but an entire thread of reviews espousing the brilliance of gruel as a paint stripper. Get this helpful little tid-bit:
“Yes, I’ve used porridge and it’s very effective. If you ‘cook’ it to the correct consistency it sticks to anything! I use the ‘value’ brand of supermarket… .It’s not really necessary to use warm porridge but I feel it’s more likely to act better on the paint….Once you’ve spread it over the plaster, cover it with cut-open carrier bags to retain the moisture and leave it for 2 or 3 days then pick it off….I wouldn’t leave it on much longer though as mould can develop with a corresponding pong.”
Having given it a try, we can report porridge may work on plaster or wood, but not on granite. Happily, we had some success with the test patch of the non-caustic stripper, so we’ve ordered enough to do one of our two walls. It arrives in a couple of days and that will be one of our projects as we move toward the holidays.
I’ll need to get my letter to Santa ready soon and see if he can send some elves to help!
