Water-based is best
Thanks to modern paint technology there is a paint for every type of surface. In most cases professional painters will select a flat acrylic paint for the ceiling, a low-sheen acrylic for the walls and a semi-gloss or gloss acrylic for the woodwork.
Water-based acrylic paints have a number of advantages over their oil-based enamel counterparts. When you’re painting, drips and splashes can be removed with a simple wipe over with a damp cloth. When you’re finished, paintbrushes can be cleaned up in water. Unlike enamel paints, acrylic paints emit almost no fumes or vapors when applied, they dry faster and they usually cost less. Oil-based enamel paints can offer superior durability and are often favored for very high quality work but for a DIY paint job, it’s hard to go past the acrylics. The types of paint below can be either acrylic or oil-based.
Flawless flat finishes
Flat (or matt) paint provides a soft, glare-free finish and tends to hide minor surface irregularities. It’s easy to apply and is the best choice for ceilings, and walls in low-traffic areas.
