Elastomeric paint on interior basement walls

[d]

I am interested in whether elastomeric paints commonly used on exterior stucco would make a good interior covering for a 150 year old stone basement. There are decades of flaking mortar, plaster patching, and white washings that I would love to seal behind a thick polymer coating.

Would it work? Any pre-treating of the walls required? Any toxic fumes issues due to spraying in enclosed space?

Thanks in advance.

Elastomeric ??? Crap ? , Paint is best on stucco or otherwise , so is removing all bad loose paint and debris and cleaning first.

Failing paint is from moisture not the paint in a basement, fix mortar and leaks, scrape , clean and use latex paint. Not Elastomeric BS,

Latex paint is Elastomeric...
