Paint Contractor Tips: Do I need to thin my paint or not?

As a paint contractor I usually get asked about working with paint, specially latex paint which is the one most used in the majority of home restoration jobs. And the most common question is to whether or not thin the paint before applying to the surface.

Well the first thing to do is to open the can (you can use a screwdriver if it is a tin can), don’t make a decision yet, you need to get a wood stick and stir the paint for about 5 to 10 minutes (this is critical if the paint is not new) and do it in an down to up motion in order to mix the particles that sat in the bottom of the can and dissolve them. You can also try pour in it repeatedly from bucket to bucket or from can to can.

After that lift the stick and see how thick the paint is by holding it over, if the paint is smooth like thick cream for example, then it is good for the go and no thin is necessary at this point, just don´t forget to have the surface ready before you paint. It is critical for you to NOT thin paint that is in this condition as doing so will make it unusable.

On the other hand, if the paint is lumpy then you will need to thin it. Now to do this we recommend you use a big bucket and prepare the water. We recommend that for every gallon of paint (3.7 liters) use ½ cup of water at room temperature. Now, don’t use all the water at once, apply some of it and see if you get the desired consistency.

Also, be aware that the amount of water you need to use to thin your paint will depend on the quality of the product, for instance, high quality paints will be thick and will probably require a little more water and don’t forget, never add more than 4 cups of water per gallon of paint. Failing to do so will ruin the paint for sure.

If you are using pints of paint then add 2 tablespoons of water per pint to thin the product. You need to be stirring the paint while you add the water, this will allow for you to see to it to have the right consistency.

Once ready use a piece of wood and test the paint. Once you see it is OK, you can apply it to the final surface.
