When it comes to home painting instead of giving preference to price, type of paint, or the drying time of paint one should give priority to the result of the paint. Both, oil based paint and water based paint have their own set of advantages. Here is an overview of oil based paint and other house painting tips that will help you in the home painting job.
Overview of Oil Based Paint
When it comes to painting house through oil painting methods, there are various coats of paint used. First comes the preparation of the wall for interior painting. If there are any holes they are sealed up, and if there are any uneven surfaces they are smoothed out using a sandpaper. Once this is done, a primer is painted on the wall surface. This ensures that the coat of paint will adhere properly to the wall surface. A primer is also necessary if you are thinking of going oil based paint over latex or vice versa. To know if the existing paint surface was oil based paint or water based, take a paint chip from the surface, if it breaks with a snap it is a oil based paint.
After this layer of primer dries, a coat of the main paint is applied, which can be an oil based paint or water based paint. Oil paint drying time is very much longer compared to the water based paints. Oil based paint drying time is higher because, they contain oils or synthetic resins as their base. So, when oil base paint dries by oxidation when it is exposed to air. But, in case of water based paints, the drying time is less, because they dry as evaporation occurs.
Fumes of Oil Paint
This is one of the biggest disadvantage of using oil based paints. But, another major disadvantage of using oil based paint is that, oil based paint fumes can be toxic and cause some respiratory tract related problems. Oil based paint has higher concentration of volatile organic compounds, which are the chemical molecules that vaporize as the paint dries. These compounds are in lesser amount in water based paint. Hence, when using airless paint sprayers and guns and using oil based paint, one needs to take care to maintain proper painting safety, by covering the body areas and by wearing mask and gloves.
Safety with Oil Based Paint
However earlier, the oil based paint used to contain many toxic chemicals in them. But, the oil based paints available today are much safer. So, one need not worry about using oil based paint, but should maintain proper safety while painting using oil paints. Many people tend to consider latex paint over oil paint, which is true on most surfaces you can use latex paint. However, there are certain surfaces on which only oil paint works the best.
Surfaces to be Painted
Oil based paints are tough resistant paints, and they make ideal for exterior painting. Oil based paints and varnishes are used for boats and shipbuilding, as they can stand the damage done by elements and salt water. Areas of the house which need to be waterproof, or floors or objects which need to stand many falls or hit, or elements are best painted with oil based paint. To name a few wood, metal objects, wall trims, kitchen cabinets, bathroom cabinets, bathroom, and exterior surfaces can be painted with oil based paints.
So, oil based paints should not be completely neglected. But, a combination of latex and oil based paints for the house painting should be done to achieve the best looking results, and resistant surfaces.
