Does the fired facade board still require additional protection?

Asked .Active .Viewed 154 times.

I am interested in the question (so far theoretically) – is it necessary to treat the fired facade board in some other way, or is it enough just to burn and sand it? Interested in the sufficiency of firing to avoid actions such as: - preservative, - primer, - painting.



Firing is not a cure-all. It's a beautiful texture at a lower cost. The second is protection against mold and mildew, with proper post-treatment. And third, you can turn crap into beauty. After the firing process, treat the composition on the basis of pine tar, if there are finances oil type Osmo, and you will be happy, bearing structures treated with pine tar are more than a hundred years


Built a house out of shipping containers. After insulating it, I decided to cover the facade with Shou Sugi Ban. Burned it with a torch. The board is planned to be 30 mm thick. I used different calibers – 200, 150, 120 and 100. At 320m2 it took 3 large cylinders of gas. The most troublesome is brushing, brushed with a nylon brush. On top of the oil Osmo for facades on three sides of the board. It looks like wenge, but a little darker. The back of the board was coated with regular oil to save money. It was cheaper than all other coatings. Took 7.5 liters (3 cans) in one layer. I waxed the ends with candle wax. Sewed vertically on self-tapping screws. Self-tapping screws buried and hid the plugs. Cork coated stain osmo. I couldn't see the fasteners from two meters away. Has stood for two years. Has not burned out. Next year I will cover the second layer and paint the windows.


In the past, foundations were made on wooden piles, where wooden piles were also fired for durability. I think this option is suitable not only for facades, but also for various terraces and patios. With this treatment, as I understand it does not require preservative treatment.


I also want to share my experience with baking. I was making beams for sheds and a board that had been previously treated with antiseptic came under the firing. So when I started to bake it, I saw an interesting effect. The antiseptic penetrated to different depths and during baking gave such an effect, as in the photo. As if the board was 100 years old and eaten by parasites and winds). Really had to extinguish in places. The antiseptic makes the smoldering worse. You can burn through the board. Who needs deep marks of time, this is an option. I painted Teknos Woodex ECO in wenge.


Wooden roofs and facades are subject to significant deterioration of the elements. Rain, hail, and ultraviolet rays contribute to surface weathering. Installation of roof overhangs, roof edge profiles and weather stripping can significantly extend the life of the surfaces. Facades that are exposed to a lot of sun require more frequent maintenance than facades in the shade of the sun. Deep charred board requires less maintenance than charred and cleaned products

It can be cleaned with a natural vinegar solution. Use a sprayer for this. Do not use an abrasive washcloth or scrubbing. Over time, small spots of weathering will begin to appear on the board. This is normal, but if there is extensive damage, you will have to replace the entire board.

Charred, brushed and stained boards should be repainted every 4 years. A new coat of stain should be applied before the wood begins to gray.

Clean the facade with water and a brush. Use natural vinegar to remove mossy growth (as described above). After cleaning the wood surface, apply a new coat of paint with a wide block brush.
