But how to pick the best paint thinner? The suggestion is not enough to make the right decision. Well, then here is the buying guide for you.

Types of Thinner

There are different types of paint thinners available in the market. You will find a specific type of thinner for acrylics, which is the case with oil-based paint. Make sure to know the type of thinner you need for the specific paint you are going to use.


Along with the thinner type, compatibility is also important. Some paint thinners are suitable for hard and strong paint whereas some are compatible with weak ones. You need to know the compatibility of the thinner before picking.

Some people use the thinner for art purposes. If you are an artist, check whether the thinner is compatible with color paint.

Cleaning Ability

Most of the thinners are used to clean painting brushes. Some even remove greases and oils from tools. So, get one with such capability. Cleaning the brush after painting will be a lot easier. So check the cleaning ability of the thinner before buying.

Drying Capacity

You may need a thinner that dries fast. It will save you a lot of time. Some people even prefer a thinner with medium-drying capacity since it helps the paint be distributed evenly for a flawless finish. Know which one you require and pick accordingly.

Bottle Size Is Also Important

A lot of people make mistakes picking the right size of the bottle. You need a large bottle for a large painting project where a small bottle will be good enough for your art job. Know your amount requirement and pick the right size.

Is It Odorless?

Finally, check whether the paint is odorless or not. Thinners with odor are not good for artistic or indoor jobs. They are unhealthy for man and make the environment polluted. Try to avoid one with a bad odor since it can make your working experience with the thinner worse.

How to Use Paint Thinner

Using a paint thinner is the easiest thing to do if the ratios are maintained accurately. It does not have too many steps and can be done instantly.

Step 1:

The first step is to choose the right thinner. The type of thinner you will be using depends on the nature of paint you are using in your work. It also depends on the technique of painting too.

For example, if you want to use the spray technique of painting, you must choose the finest paint thinner for the spray gun.

Step 2:

After you are done selecting your right thinner, then you can move to the main work i.e., thinning. You need to be careful with your hand while adding the thinner to the paint. You must do it little by little. Don’t be hasty on this step.

Add them maintaining the right ratio of paint to thinner. You may find the ratio guide on the manufacturer’s instruction if you need assistance. The amount of thinner must be less than the paint so that the paint does not become all runny and less pigmented.

However, the paint must be made a little thinner while spraying.

Again, you must keep an eye on when using paint that is lower in temperature than normal room temperature. Cold paint seems to be much thicker than normal paint.

So, you should not use too much thinner at a time while dealing with cold paint. Rather wait for a little as you mix your thinner.

Step 3:

And lastly, as you finish thinning your paint, now it’s time to test it. You must not directly put the paint on your work.

First, you should try out the thin paint as a test. You should check if the texture and consistency are just how you need it. This eliminates the risk of unwanted mistakes.
