I need a primer coat and a finished color. Because of high humidity,
I plan on using an oil-based primer and tinted latex as the finish
coat.
I want a sand texture wall and usually add the dry texture plastic
particles to the primer and apply with a roller. I am thinking it
would be less of a mess to roll the primer on and then add the texture
to the latex finish coat. Any reasons why this would not work? thanks

The standard wisdom is to never put latex over oils though it can be
successfully done as others have pointed out. Why not just go with
latex throughout??
