Containing either natural oils or a synthetic alkylate, oil-based paints are more durable than latex paints. Oil-based paints should be used on surfaces where you want the finish to last for a long time. While this kind of paint has a stronger odor and takes longer to dry, its durability is unmatchable. The strength of oil-based paints makes them a great choice for moldings and trims.
Prime. Dark colors, stains (once sealed), and previously unpainted surfaces (drywall, spackle, etc.) will need a primer coat, usually white. NOTE: most paint stores & home improvement centers will now tint primer (at no charge) to match fairly close to the color of the finished coat, that way two coats of primer need not be applied. Although not all surfaces need a prime coat, skip this step at your peril! Dark colors will likely show through the first -- or even the first couple-- topcoats of paint. Sealants and unpainted surfaces like spackle patches will absorb or repel moisture in a topcoat at a different level than the areas surrounding them. Applying a good primer coat will help even out these differences. Primer equalizes a wall to a uniform surface. It's like erasing a canvas before drawing a new picture. Although some will argue the point, you generally don't need to spend a great deal on primer or buy special primer. A cheap, 5 gallon (18.9 L) bucket of plain, flat white paint will usually do the trick and cover a large area. Give your primer at least 24 hours to dry (follow its instructions) before applying a topcoat.
The Ceiling. For ceilings, flat is recommended, except semigloss or satin should be used in bathrooms with showers/tubs. Some customers opt to go with a different finish for ceilings in general, to create a specific design look, i.e. high gloss ceilings on dining room tray ceiling to make a statement, or eggshell ceilings throughout to look modern and make a statement.
Priming is compulsory if you're painting over a darker color, or on a new drywall, but it's a good idea to include this step before any paint job. A primer is necessary because it blocks any stains from bleeding through. It is also important because it prevents any blisters and paint-peeling by improving paint adhesion. Lastly, primer is a good idea as it allows complete single-coat coverage of the walls. If you want a better appearance, you can tint your primer with the final color you intend on using on the walls. Most paints today come with inbuilt primers, but an old school primer is still a better option. Before you start painting, remember to use painter's tape to cover your door frames, window sills, and any switches on the wall.
