I recently refinished a small bedside table with a simple faux finish / paint effect finish. For this project, I used what I had around: artist's acrylics (Liquitex, heavy-body stuff), mixed with water, some Golden acrylic glazing medium (for translucency), a touch of Floetrol (for leveling), and some drops of XIM Latex X-tender (because it's better than Floetrol but I found it in my basement late :)). First coat: titanium white mixed with a tiny bit of dry pigment, second coat: mostly white. It looks a bit Gustavian, which is what I wanted.

Question: will this mix have "blocking" problems (i.e. will things stick to it). I know that *latex* paint is bad for furniture, because the "latex"/vinyl resin has blocking problem. I also know that 100% acrylic coatings (eg. BM waterborne Satin Impervo) do not have blocking, because there is no vinyl resin. Because artist's acrylics have (I suppose) 100% acrylic, then I guess the answer is "no", but wanted to check with you.

If there will be blocking problems, should I follow the usual strategy and wait the finish to cure (how long), and then add one or two coats of water-based poly. (I know that poly would add wear resistance anyway, but since I want this to be a "rustic"/Gustavian/old-looking piece, I don't mind if it wears).

Thanks!

I don't know much about art paints but generally the more pigment the longer it takes to dry. I would probably err on the side of caution and apply a coat or two of poly and play it safe.
