Hello,

we want to plaster the underside of our carport as well. The battens are made of wood, and plaster carrier boards are to be installed. Which boards are most suitable for this? Soft fiberboard? Our builder is a bit concerned that the plaster might crack. I have often read that eaves are also plastered. Isn't that basically the same principle?

Both systems mentioned here are good and should solve the problem.

I would need an assembly diagram so that I can understand it better

We built a wooden carport and had it plastered so that it looks like brickwork from the outside, matches the house, and is protected from the weather. However, we left the wood exposed underneath because it’s very practical for quickly hanging or attaching things. We also like the look, but of course, that’s a matter of personal taste.

For the plaster base, we used simple 1000x500x30mm (39x20x1 inch) styrofoam boards from the hardware store and glued them onto the OSB panels with construction adhesive. The plasterer then applied his mesh/undercoat on top, followed by the finish coat. I can’t say if this method works fully upside down, since for us it was only used on the walls. But it has held up without any problems for 1.5 years now.

@Alessandro Could you please tell me how you ended up doing it? Thanks!

Nothing has happened yet. However, a wooden underside will be installed.
In the end, the risk of cracking was too high for me. Since neither my building contractor nor the carpenter had done this before, I did not want to be a test case.

It is a masonry carport that is integrated into the house.
That’s why the same appearance should be maintained throughout.

@Alessandro Was the front view/the canopy of your garage built with masonry or concrete? Or how is it clad?
