    I want to spray paint the inside of my concrete sectional garage walls but the walls are very smooth and damp, Is there any special precautions i need to take? I will be using some white floor paint i bought and mixing it with cellulose thinners.

    I normally use Masonry paint. The first coat on bare concrete should be thinned at least 1ltr water to 5lt (I thinit down more) to act as a primer, next coat thin just a little. No other primers needed. It is sprayable but goes on luverly with a roller in no time. Though if walls are damp they need rectifying, If exterior walls are bare I coat over with silicone.
    I personally wouldnt use the floor paint (cellulose thinners ??) on walls, It will peel off in time without a special concrete primer (alkyd resisting).
    Good luck ..
