Is it ok to paint on asfaboard

[Derbyboy]

I will replace vertical cladding that is nailed directly onto asfaboard. The cladding is spaced 5 mm apart and during the last painting, it was painted in place, which resulted in paint on the asfabords.

Now I am going to change the facade color from brown to black and wonder if I can paint the lines that exist today between some of the cladding boards?

Sounds strange, do you have any picture of that facade? I haven't seen that model of facade with asfaboard but with masonite (painted) instead.

This is how the facade looks. I have removed a plank.

The house was built in '74 and this particular part of the facade faces directly south.

Are there no lockbrädor?

 

[Derbyboy]

No lids!

And that's why there are brown stripes on the asfaboard.

Not much, but since I'm going to replace the panel, I thought I'd paint the stripes?

Strange! it should rain/run directly in, but if there are no damages, it has apparently worked anyway. It probably can't hurt to paint if you intend to continue with the "style"

 

[Derbyboy]

The explanation for the lack of damage is that the eave is 70-80 cm.

I was thinking of applying some diffusion-open facade paint, the same one I use for the planks.

On the same track: if it worked before, do it exactly the same way again. Sometimes you get pleasantly surprised that things that “shouldn't” work still do.

 

[Derbyboy]

Well, the actual construction should not be changed. The question was whether it's possible to paint on asfaboard and if there's anything I should consider.

 

[claym]

Since the board is already painted from before, there shouldn't be any issues painting it again with the new color. I assume you will have to press the brush with paint so that it gets into the gaps.

 

[Sittställning]

Aaarå, you're not supposed to paint the whole board so it shouldn't be a problem at all as far as I can think of.

Since the board is already painted from before, it shouldn't be any problem to paint it again with the new color. I guess you'll have to push the brush with paint so it gets into the gaps

The new panel is placed on trestles indoors.

I will be replacing vertical paneling that is nailed directly onto asfaboard. The paneling has a 5 mm gap, and during the last painting, the paneling was painted in place, which resulted in paint on the asfaboard.

Now I am changing the color of the facade from brown to black and wondering if I can paint the gaps that currently exist between some of the panel boards?

No problem painting, choose alkyd/oil-based paint.

I previously had a house where the entire facade was painted asfaboard with battens, so it looked like a batten panel. It was 40 years old when I bought it and completely flawless.

As long as only the brown stripes are painted, it's fine. The Asfaboard is diffusion-open and should not be sealed with paint, as then penetrating moisture may have difficulty drying out. Especially if there is some form of vapor barrier on the inside.
