Get exposed beams bare from burn marks and paint?

[Blomqvistarn]

I am in the process of exposing the intermediate floor structure in a house from the late 1800s and am wondering which method would be best suited to restore the beams to their natural wood state. In the 80s, the house suffered minor fire damage which left scorch marks on the underside of the beams. During the restoration after the fire, the ceiling was sprayed with something I believe is white odor-blocking paint, but I am not sure.





Please feel free to provide tips on suitable methods and tools to restore the beams to their natural wood state.

suitable milling tool or plane

Which milling tool do you suggest as suitable?

I've considered an electric planer, but there are some rusty nails in the wood that have broken off during removal.

Sandblasting?
But maybe it will get too dirty inside?

High-pressure washer or steel brush on an angle grinder, preferably slightly worn so it doesn't take too hard.

I vote for isblästring.

Trying to keep a tight budget, otherwise I agree that ice blasting seems like the best option.

Fixar_Krille: Steel brush, then, like this one?: http://www.clasohlson.com/se/Ståltrådsborste Bosch/Pr409372000

I think those beams look like they are intended to be built in. Probably with some old-fashioned broad panel nailed underneath. Beams that were meant to be visible are usually somewhat oxhyvlade and smooth. Often with a small profile or chamfer planed on the corners downward.
It starts to look completely wrong to have roughly hewn beams visible. It does not fit with the tradition at all.

Exactly, hence the purpose of the thread?

Why do you want to keep them exposed? Aren't you planning to have a ceiling?

 

[Blomqvistarn]

Terribly sorry if it wasn't clear, the beams are to be exposed and the ceiling between the attic should be raised for higher ceiling height. The beams therefore need to be tidied up.

Answer wire brush. The one I think works best is the one two steps down on the Clas O page, not a cup brush but a circular twisted brush. But it takes a bit hard when it's new, so take it easy. Half-worn, it's super. It's a pretty fast method.

Bad luck that I bought the other two and not the one you recommended yesterday at Clas. I'll give these a try after the Christmas break.

I have seen a patination machine that was basically built like a jointer where the cutter was replaced with a steel brush. Such a machine would have been suitable here. However, I do not remember what it was called. I think it was made by Mafell, but I'm not sure about that. In any case, it is not in the assortment now.

Bare wood is easiest done with the chainsaw, looks damn nice to look at afterwards :wow:

Just don't forget to block paint EVERYTHING. Smoke and odor are more stubborn than the goat and the pig combined!
