Help With Plywood "siding" Which Has Been Paintedfha/rd Loan

[Riick]

Look at the edges, if they are not spreading / delaminating, it's probably exterior grade; the essential difference is the type of glue used. However, the point is that the paint is peeling off, and letting the (ply)wood weather.
No matter the construction of the exterior - plywood, plain boards, whatever- the loose paint needs scraping and the underlying substrate needs a quality paint job.

Correct. The difference between interior and exterior plywood is the glue that holds the plys together. Interior grade will start to delaminate very quickly when it gets wet. The siding in the photo exhibits a lack of maintenance but no substantial deterioration. The split/crack was probably there when it was installed.

My bet is that its exterior grade but needs immediate attention for caulking, scraping, and painting.

T-111 comes as a couple different but always has 8" spaced grooves vertical on the sheet (4x8) - There is an OSB product and a plywood version

These people loved OSB enough to do the entire interior in it.

Considering the state of my office, I am not about to criticize someone's choice in interior material.

That would be a likely deal killer for me.

But it goes so well with the B/C plywood flooring.

It had a really nice Accessory Dwelling unit.
