What is a oil paint?

Painting is the nation’s number-one home-improvement project. It can help you change the look of a room from dull to brand new. Here’s an interior-painting primer, starting with the pros and cons of oil-based and water-based, or latex, paints. Oil-based paint is more durable, but it takes longer to dry, and cleanup requires turpentine or paint thinner (mineral spirits). Oil-based paints are made with either alkyd (synthetic) or linseed (natural) oils. Alkyd paint is more common because it is less expensive and tougher. Oil-based paint is good for trim work because trim takes more abuse over time than do walls.

Oil-based (alkyd) Paint

Oil-based paints offer superior one-coat hiding and better adhesion to difficult surfaces (such as those not thoroughly cleaned). Oil-based paints allow for greater open-time (or length of time the paint may be brushed before it sets), exceptional flow & leveling (finish smoothness) and resistance to abrasion, once cured.

How to Paint Over Oil-Based Paint

Oil-based paint once ruled the world of interior paint for high-impact areas such as trim work, doors, and cabinets. Yet no longer. When it dries, oil-based paint emits a host of VOCs (volatile organic content) that are harmful to the environment. The paint is often messy and smelly since mineral spirits or paint thinner must be used for clean up, not water.

If a house is old enough, it is inevitable that it will have oil-based paint somewhere since water-based latex paint wasn’t introduced until the 1940s. And newer houses might have some areas of oil-based paint since it is not entirely banned: Oil-based paint is still available in quart sizes or smaller. Many professional painters even favor oil over latex for a smoother, rock-hard finish that leaves no brush marks, gaps, or bubbles. You’ll typically find oil-based paint used on door casings, trims and moldings, mantels, cabinetry, and shelving.

Can You Paint Over Oil-Based Paint?

Latex paint (and even other oil-based paint) can be successfully applied over older oil-based paint as long as the surface is fully cured and there is nothing inherent in the coating that prevents another layer of paint to be added. Preparation is important. Glossy surfaces will not take a second layer of paint well, so they need proper cleaning and priming achievable by following these steps.

Are you excited about painting your new house but do not know where to start? If you are wondering what type of paints are the best choice then you should read further. With so many brands and colors available in paints, it can be quiet confusing. Paint quality makes a lot of difference to the look of interior space and one needs to choose wisely.

Three main types of paints are oil, latex, and acrylic that are available in the market. Out of these three, you need to decide which medium is best for you as per the features that they offer. While Acrylic paints work on all surfaces oil may have more shine and luster. These are a great medium to work within your interior space and both have their Pros and cons. If you understand the difference between the two it can help you make better decisions and you can choose the right color quality for your home.


Talking about oil paints, it is quite self-explanatory. These are oil-based colors and therefore have an exquisite shine to them. At the same time, they are toxic and therefore one should avoid close contact. One of the best features of these paints is that they blend better if painting a large area and are hence preferred for a larger cover.

The fact that they are most difficult to get out is what makes them tough to scrub off and they last longer. If spilled or spread on something they may give tough time. Choose oil Paints carefully as they emit a strong odor. So while applying paints open windows like a lot of smell can accumulate and irritate. They usually come in huge size cans with gallons of paint.


These are among the most popular paints used for an interior purpose. They come in multiple finishes and give a great look. They are much easier than oil paint when it comes to cleaning. Also, they dry too quickly hence are a bit rigid. Large areas may be difficult to work on for the same reason and therefor Acrylics are not preferred for such vast spaces.

Also, acrylic does not blend and mix well and dry too quickly. Though specialized technique if a painting can be used for best results. The trick is to have water in a bucket while applying these paints, also you can squirt water on the wall for better blending. You can use water-based acrylic paints also as they mix well with water. Acrylic resin is chemical-based paints that have a great amount of elasticity and show the result as per temperature. If the temperature is hot then they expand and in cool temperature contract. Therefore their application is based on the same. This also helps to reduce flaking and cracking greatly and makes them more durable for use.
