How to Use Oil-Based Paint
There are several reasons for using oil based paint as opposed to latex paints, and each individual circumstance will determine which paint is the right one for the job at hand. Oil based paints tend to be heavier, creating better coverage per coat, but also have more drag, which makes it more likely to create noticeable brush strokes. Oil based paint should never be used on stucco, masonry, concrete, or galvanized metal without the surface first being primed with primer. Oil based paints are also more susceptible to mold and mildew, so make sure to get paint that has mold and mildew preventative qualities to it. Here you will find the information needed to using oil based paint.
Step 1 - Prep the Area to be Painted
First, you should take care to prepare the area that will be painted with oil based paint. Because oil based paint requires paint thinner to clean up any spills or messes, you will want to take extra care to cover flooring, fixtures, windows, or surfaces that are inappropriate to paint with oil based paint. Take extra care to cover surfaces that could be damaged by paint removal with paint thinner, such as carpets, wood floors, or furniture.
Step 2 - Ventilation
Make sure that the area where you are working has adequate ventilation before you begin working. Oil based paints have very noxious odors, and should be used in a well ventilated areas. Open windows and, if necessary, bring in fans to give additional ventilation to the work area.
Step 3 - Applying Paint
Pour some paint into a tray and work on a test patch with the paint. Try different types of brushes (bristle or sponge) and rollers to achieve the desired effect in the application. If a bristle brush is creating large brush marks, try using a roller. A roller and sponge brushes will give a slight texture to the paint that many find more appealing than brush strokes.
Step 4 - Letting the Paint Dry
You will want to give the paint adequate time to dry between coats. Read the label on the paint can for drying times, but keep in mind that heat and humidity may play a role in drying times as well. Many oil based paints take twenty four hours, or more depending on conditions, to dry thoroughly. Making sure that the paint is completely dry in between coats will ensure quality coverage and will ultimately minimize the work that is done.
Step 5 - Cleaning Up
Thorough prep, draping, masking and cleaning up drips and spills as they happen will cut the clean up time considerably. You will need to saturate old rags with paint thinner, and use the saturated rags to clean up the errant paint. Dispose of saturated rags appropriately. If it will be some time before they can be disposed of, they should be stored in a steel bucket of water, as they are a fire hazard.
