For as long as it takes for the surface to be completely dry.
It should tell you on the can as every paint is different.
Latex body suit can be worn for long periods of time. Unless allergic to latex you should not have any problems with wearing the suit for a long period of time.
yes but you cannot put latex on top of oil based surfaces You actually are NOT advised to put oil over latex surfaces, which is why you're supposed to prime will an oil-based (alkyd) primer. Latex and Polyurethane should always have a layer of oil-base beneath it.
Rustoleum is a brand name; however, as long as the surface is clean, oil-free and dull, you can paint any oil or latex based paint over a latex surface.
yes as long as the paint is dry.
Yes, as long as the latex paint is clean and sanded to a dull finish.
yes you can i dont worry about what type of paint is on walls as long as it is dry it dont matter
You should be able to use a gravity feed HVLP spray gun to spray latex paint as long as the volume is at least 12 CFM. Check the paint's data sheet to determine the proper thinning required.
Yes, you can generally paint high gloss latex over flat latex paint. But you must do all the preparation work in the best tradition of any professional painter. All "flaking" must be removed and the raw wood primed. This will present a "smooth" surface for the new coating. Additionally, everything that is to be painted my be scrupulously clean and free of anything that will restrict the new latex from sticking to the old.
Latex paint frozen in the can, should not be used. Freezing damages the paint, making it unusable. Once latex paint is applied to a surface, freezing will not harm it.
If you really want to ... yes. It might cause some issues later but should work for the most part as long as you apply a thin layer of paint. Acrylic house paint is normally a latex paint, so there should be no problem painting over a latex with acrylic. The only exception is if it is a solvent based acrylic silicone type paint. In this case, the coating will melt the latex paint, and if overworked while rolling, mix on the surface, which is normally a driveway or floor, discoloring the top coat.
As long as you sand & prime first, in most cases just latex primer applied before painting with the latex paint. If the old paint is really old, be careful about sanding, it may contain lead.
