Flat latex wall paint is fine.  The latex-based Kilz is fine.  Acrylic paint is fine.  Oil-based Kilz is okay if, AND ONLY IF, you are sure you will be using oil-based paints on top of it.

Actually, nearly any paint is fine, with one warning:  You cannot use water-based latex or acrylic paint of any kind over an oil-based paint.  It won't stick well, and if it sticks in the beginning, it will peel.  (We don't need to go into how I discovered this  :oops: --- before I learned that it was indeed written in stone.)  Never, ever.  And never try to mix the two...  really bizarre results. (This was an accident with someone else's paint-- I wouldn't have done it had I known.)

And I wouldn't want to try flat paint over glossy paint, even if both are latex.  I don't know for a fact that it wouldn't work, but I would just prefer not to ruin my work with the discovery that it's a bad idea.

And it's okay to mix acrylic paints with latex.  I've used the intense acrylic tube paints to tint latex wall paint, and it worked fine.  (A good thing, as it was an 8' x 16' display for work.) 

After the first oil/latex fiasco, I have learned to to make small test sample.  And if I know I'll be trying something different, I make a small PM sample (flat is fine) of the same materials, and test it there.

Severely pared down in size, this site might give you some ideas for a small castle:

Actually, that one looks like it would be easier. 

Castles usually look great, but when I see one, all I can think of is 'drafty!"
