We’d really hummed and hawed about what to do about the basement parging for most the winder and early spring. Although our plan had been to do the house all black initially.
But last year we’d hesitated. And I’m not entirely sure why. We couldn’t run the wood siding all the way to the ground, like the rendering shows, because of the 8” of foam on the exterior basement walls without some seriously extensive strapping. Alas we had the stucco guys parge the basement foundation and then leave it while we contemplated our options: leave it or go all black.
While taking photos for the post about the concrete retaining wall, Darcie, my wife, said, “The house doesn’t look right. It looks like it’s floating. It’s weird.” She proceeded to spend the next several days playing with Photoshop, filling the gray parging with black and analyzing it from multiple angles. After a week of scrutinizing the Photoshopped images, she said, “Look. We should do this.” Pointing to an all black house.
If there’s one thing I’ve learned is that once my wife has made up her mind, it’s best not to disagree. It is only futile afterall. “Yes honey,” I replied (these two words are the most important for a husband to know, by the way).
So I called the stucco guys and asked them to come back. It ended up taking a number of weeks for them to finally show up (typical). But only a couple hours for them to transform the house.
I gotta say, I don’t know why I’d hesitated, because once your go black… well, you know the rest.
We knew we wanted a black house. In fact, when designing the house, it was one of the only things that really remained consistent and we didn’t change our minds about (ok, truthfully, we strayed a little bit – testing the waters, but as they say, once you go black, you probably won’t go back… or something like that). Our previous house had been painted black by the previous owners (we are since soul mates) and we loved it dearly. But really we did not not want to simply paint our new house black. Paint is great for covering up years of other layers of toxic paint, as in our old house, but not as an initial coat. So, what to do?
In the process of researching, planning and designing the house, we collected hundreds of inspiration pictures. The majority of my “architecture” folder on Pinterest is of black houses, and each one I’d look at and try to figure out what they used: paint, stain, or something else.
One of the first “something else” option we were initially really drawn to the traditional Japanese siding treatment called “Shou-sugi-ban”. Taken from a Treehugger article on this process:
This is a traditional Japanese method of preserving cedar, where it is burned enough to create a layer of char on the outside. The char serves a number of functions: it seals and preserves the wood, it makes it significantly more fire-resistant, and termites and bugs hate it.
It is said that this type of treatment can allow the wood to survive for 80-100 years without maintenance and much longer if treated with oil every 15 years.
Here is an impressive video of the traditional process in Japan:
Ok, so just imagine doing that 200 times over to clad your moderately sized house. Now that is labour intensive! Most people nowadays, from what I’ve read, use a blow torch to char each board, then dunk it in water, scrub the charred bits off, and then oil it. Even with a blow torch this a crazy amount of work, but in the end you get something really impressive and completely unique.
I really thought we were going to do this for our place, however, there were a few reasons we abandoned this idea. Firstly was the obvious: OMG, that would be so much work!! Second, cedar is crazy expensive right now, running in the range of $7-9 per sq.ft. But the final reason, was that we had heard that someone had decided to do a house in shou sugi ban in the City. Curious to see it in real life, we drove over to take a look at it. And well, to be honest, we really hated it. Perhaps it was just the people who did it did a bad job, but it looked really… gross. It basically looked like a house that had had a fire recent go through it (which I suppose is true). I think I would like to test it out on a shed or coffee table or something before I invest thousands of dollars into the siding of my house and ended up hating myself over it.
So, we turned to the natural and perhaps, most obvious option, stain. Stain is all well and good, but you really need to stain your wood every 5 years (or less) to preserve the wood and keep it looking good. And really, you still should use cedar to have optimal rot protection with plain old stain. That is until my wife came across a little black Swedish house.
Granted, this house is actually sided in plywood, which I would never do, but what intrigued me was the rich black colour, that the grain of the wood still came through (not painted), and that they had used a siding that was not cedar.
As I read more into this, they used “black tar” for the siding. Through some detective work, we eventually found this same house linked to a Swedish product called “Auson black pine tar.”
I had never heard or seen this product before but I was very intrigued. Also, it was Swedish, and seeing as our house had a lot of Scandinavian inspiration, this only seemed fitting.
We found that the product was available in Canada through a website called Solvent Free Paint. Score. We emailed the company to learn a bit more about it:
“Genuine PineTar is one of the more effective wood preservers we’ve seen, and it is all-natural, which is amazing. In Scandinavia, they have been using PineTar for around 1500 years as a preservative on everything from stave wood churches to wooden splint roofs to Viking ships, and it is still the predominant choice for continuing to preserve these old wooden structures to this day. Amazing. In fact, the heritage arm of the government of Québec has been making studies on this here with respect to preserving wooden roofs, and their current recommendation is to use pinetar.
PineTar is made from burning the pine resin out of the stumps of pine trees. The sticky resin is then collected and cleaned to various degrees, and pigment is even added for colour. In this state, PineTar has the consistency of molasses and can be used for preserving wood, even below grade. Above grade, we recommend mixing the pinetar 50/50 with Allback Purified Raw Linseed Oil and applying warm so that the pinetar and oil mixture really penetrates the wood. This mixture offers the best of both preservation and nourishment for the wood; it also takes down the stickiness of the surface so that it is more pleasant to touch or walk on.”
Even better, this product is ideal for use in Scandinavia, where pine and spruce are much more readily available and cedar is not. It preserves the wood and needs to be recoated only once every 15 years.
Bingo, we’d found our product. We ordered a few litres of this stuff. We had debated about using cedar for our soffits as well, but once we saw this, we realized we could use pine with a natural clear pine tar for much less than half the cost of cedar still.
We started out with the soffits, which would be easiest to install first. Yes, it is true that most people use aluminum or vinyl vented soffits, which are fool proof but are so fucking boring. Instead, we purchased 1×6 tongue and groove clear white pine. Now one thing you need to know about staining (or painting) wood for siding or soffits, is that you mustn’t let any part of the wood be left untreated (otherwise the lifespan of the wood will drop by 50-75%, so preparation is key)! That is, you must stain all six sides of the wood. For the tongue and groove pine, this meant that yes, we had to stain the tongue AND the groove, which is a crazy, tedious and annoying task.
We had about 800 sq.ft. of soffits to stain, all sides, twice. It took us about 14 hours, but it looked pretty nice by the time we were done. The pine tar was actually easier than we expected it would be to use. Once mixed 50/50 with the linseed oil it was really just like a slightly thickened stain. It brushed on easy and evenly. However, we had to keep it warm. On the hot 30 degree Celsius days it was easy, but on the cooler day we had to heat it up on the stove in the shop. Also each coat took about 4-7 days to dry and still had a bit of residue on it that hopefully will dry someday. Surprisingly, it was not at all sticky (I had fears of moths and dust sticking to the house).
Now as for venting of the soffits, there is a calculation of square footage of ventilation versus square footage of attic space which is approximately 1 sq.ft of venting to every 100 sq.ft of attic. We figured out that that meant about 3/4″x30″ gap lengthwise along every fourth board, would be about right. We used a router to cut the gap and covered it with a bug screen. Here’s a photo:
I was so impressed with how well these turned out. Much better than I’d expected to be honest.
Next up was the siding, which I was most excited about. We ordered the clear white pine siding as a “shiplap reveal” in 1×8.
That pile took a ridiculous amount of time for us to work through. I had expected it to go relatively quickly seeing as we did not have to stain a stupid groove, but 30 hours later we were finally done. Exhausted, but man did it look badass.
Over the next two weeks the contractors, chipped away at installing the siding. This too took much longer than they had expected too, particularly from having to stain the ends of each cut. But seeing that siding go onto the walls, I knew we had made the right decision.
Well, after twelve revisions and eight months of planning, designing, redesigning, changing, scrapping, planning, and redesigning some more we’ve finalized the house design at last. It’s funny, we had been so sure of what we wanted and didn’t want before, but gradually this all changed. I’m super happy with the design. And although it is different in some ways from our original plan (i.e. basement, open kitchen/living/dining room), it is more true to our original vision then we had ever expected: a quaint, simple, modern farmhouse. It’s crazy to think about how far our design gradually strayed from this original vision before we finally were guided back towards the root of what we wanted.
In a lot of ways designing the house has been a full circle – as we meandered away from our vision, only to come back to it. It was also an evolution. The final product was far better than what we had ever originally envisioned. So I suppose you must go through the process. You are never going to get what you want the first time through, despite how confident we felt that we knew exactly what we wanted. We didn’t. We needed to explore. We needed to think about all kinds of scenarios and possibilities before finally discovering what it is that we really want.
And so, here it is. I cannot wait to see this become a reality.
I love black. Black is the new black, I say. The white door on the yurt was just not flying. We debated about painting some kind of mosaic of fish and swords and skulls, but in the end decided that a black door would be best. You just can’t go wrong with black.
