What kind of siding is this on a home built in 1958?

This siding appears to be prefabricated panels of some sort?
Maybe I’m wrong.
I’m not talking about the engineered wood panels at the top of the wall
Please give me your opinion about what the lower panels are.
To me it looks like some kind of faux stucco or faux plaster. It was face nailed by the edges/seams. The joints were sealed with some kind of cementitious product. Maybe a grout at the seams? They were rigid panels, and not spongy like EIFS.









Hardi and a few other companies sell 4x8 panels of faux stucco.

This a wood framed wall?

Is it hard coat stucco on sheathing or wood panels?

Morning, Adam. Hope to find you well and in good spirits today.

The first gable image, not talking about the what you referred to as ‘engineered wood panels’ at the top of the wall, but the reverse board and batten siding in the gable end.
Below that, I would say it appears a second >< 3/4" plywood sheathing and stucco.

Lot’s of weak unfinished joints.
As with any siding. Look at the of the finished area and how it meets up with the foundation.

Thats my wag.

That nail pop looks like it was stuccoed over. BTW, good photos.
Looks like someone stuccoed directly onto some siding panels. Definitely different than what I see.

I would say those panels are not original to the home. I say panels because of the exposed nail and the seams that are visible between the panels. Masonite made panels with a stucco look but they did not have the mesh I’m seeing in the one of the photos that shows the base. Without being able to touch and tap on this, I would just have to call it an unknown cladding with a stucco like appearance that has a thick coating of paint. Then I would note the cracks, etc. and make whatever recommendation I think is needed.

Masonite brand faux stucco. I had a storage building once with the same stuff. Came in 4x 8’ sheets that had a slight shiplap type long edge if I remember correctly. This would have been available in the late 70’s or early 80’s but might have had a much longer retail availability. Looks like a troweled on finish product at seams.

Agree that they look like faux stucco sheets AND they appear to be installed over T1-11 type siding.

It’s a wood-framed wall with what appears to be fake stucco panels. The coating appears to be made in a factory.

It looks like the nails and panels were painted over with some tan-colored paint. The seams, ends and edges were the only places where it appeared that a trowel had been used to apply some cementitious product on site.

When I tapped on in, it felt like it was a super-hard, dense, but thin finish over a cardboard or thin OSB sheathing.

This is super helpful and seems like the most likely product we’re looking at.

Thanks for the clarification about the T1-11.

I am curious about how they handled transitions such as this. (I also see new soffit material that they elected not to caulk.)

I’m also curious, Brian. When I looked at this siding I was with an agent who was showing me the property that I want to buy. I have not inspected the property yet.

However, I don’t see any flashing at that intersection, which would be a concern. If I inspect the property I will bring a ladder over there to look at it more carefully. The lack of caulking at the soffit is also a concern of mine. Thanks Brian.
