With the Zehnder and the Mitsubishi systems installed, I had some time to kill waiting for the siding guys to start, and for my first blower door test to take place, so I moved on to painting my structural steel beam and the exposed concrete walls in the basement. Apart from a couple of walls for my wife’s office that would eventually be drywalled and painted, and a decorative finish for the concrete floor, these were going to be some of the limited finished surfaces in the basement.
We’re glad we decided to leave the basement ceiling unfinished. In doing so, not only did it mean a more straightforward installation process for mechanicals, it also means if any issues develop in the future we’ll have easy access to identify and solve any problems.
I debated whether or not to spray the basement ceiling — the floor joists and the underside of the sub flooring — but decided that the color change (some shade of gray? black?) wasn’t worth the effort.
Although obviously not to everyone’s taste, we like the unfinished look of the ceiling, especially when combined with the texture of the painted concrete walls and our painted steel beam (not to mention the eventual decorative finish for our concrete floor slab — I’ll go through the details in a future blog post since it was applied much later in the build).
For the beam, I first used a wire brush and some sandpaper to remove any loose and flaking rust. Using a Sherwin Williams primer, their All-Surface Primer tinted gray, I applied a heavy, uniform coat to help prevent the return of any rust in the future (keeping humidity in the basement under control should help a lot in this regard).
After priming, I then applied two coats of a Safecoat product, their semi-gloss in Patriot Blue.
If I could do it over, I think I’d use Safecoat primers and paints for almost all of the interior surfaces. For the sake of convenience, since they have stores near me, I mainly used Benjamin Moore’s Aura Matte and Satin for walls and trim, and ended up mostly disappointed with their performance — hiding is pretty mediocre, flashing when you try to do spot touch-ups, and over-priced for the level of quality. Benjamin Moore does a great job with their marketing materials and with the look of their labels, I just wish the same level of thought and attention to detail went into the quality of their finishes.
Safecoat is available at various stores in the US, but unless you want a stock white, tinting may happen at Safecoat headquarters before shipping to individual stores, so there can be a wait involved (check with your local supplier for details).
I had good luck ordering from Green Building Supply in Iowa. After ordering online, the products are shipped directly to the job site or your home. This gives you access to high quality No or Low VOC products that, at least in my case, are otherwise currently unavailable in local hardware or paint stores.
Unfortunately, they can’t ship during cold spells, since the paint could freeze and be ruined. When it was cold and I needed product, I found Premier Paint and Wallpaper just outside of downtown Madison, Wisconsin (about a 2 hour drive for us). They’re a family-owned shop, and it shows. They have a nice selection of Safe Coat products. In fact, their wide range of products from various brands is impressive, and the people who work there are really helpful and just easy to work with. Unfortunately, I haven’t found a similar paint store in my area. Around me, Benjamin Moore (aka JC Licht), Sherwin Williams, and Pittsburgh Paint stores dominate the market. The smaller mom-and-pop stores, for the most part, don’t really exist anymore, which is a shame.
The Safecoat products that I’ve used typically have some odor, but what little smell they do have tends to dissipate rather quickly (this is particularly noticeable if you change back to a more conventional coating with more VOCs that may take weeks before its distinct odor finally disappears).
It’s a shame that so many structural beams end up covered over, normally considered too humble, i.e. ugly, to be left alone. In keeping with our Urban Rustic design aesthetic, we think that if they’re given even just a little bit of attention and care they can prove to be a real visual asset to a space, especially in a basement if a more relaxed, informal look and feel is acceptable or even ideal.
Leaving the spine of the house exposed like this with a bold color emphasizes the job it’s actually doing, and it honors the material by making it front and center visually in the space, rather than trying to hide it away behind drywall or wood. This seems only appropriate since beams like this help keep a house standing upright.
Once the beam was completed, I moved on to priming the exposed concrete walls.
Paint color can be a finicky thing. After priming the concrete walls, I used a Benjamin Moore color, Jute, as the finish coat. In the basement it looks great, exactly what we were looking for: a nice, warm neutral khaki color. Upstairs, however, when I later did a test swatch on the new drywall this same color looked horrible, taking on pinkish flesh tones, so we ended up having to use a different color for most of the first floor. Testing out colors, even in relatively small areas, can save a lot of time, money, and headaches later on.
It was really important to me that the basement foundation walls be left exposed, with no insulation or drywall.
I wanted all of the texture, imperfections, and overall character of the exposed concrete to be vividly on display. Arguably, once painted, these imperfections become even more pronounced.
