Latex is one of the easiest paints to work with. For example, it is ready to go the moment you bring it home – but in the mixed form. When you purchase fresh latex paint from the store, you need to thin before use. Otherwise, it won’t work with brush and roller applications. Companies make viscous latex paint, which works with limited applications. So, to use it for a variety of applications, it is mandatory to thin it. Let us tell you how to thin latex paint. Read on!
How to thin latex paint?
There are two categories of paint, which are water-based and oil-based paints. You can think of oil-based paint with petroleum products. On the other hand, it is easy to thin latex with water. Water is a good carrier of paint products, particularly latex paint. If you want to do this accurately, you need to focus on the viscosity of the paint and adding the right amount of water.
Required Tools and Equipment
To make the latex paint thin with water, you need a metal spiral power mixer, cordless drill fluid measuring cup, latex gloves, and fine mesh cone strainer. The materials you need are latex paint and water at room temperature.
Required steps to thin latex with water
It is important to acclimate the latex paint before thinning it. Usually, people do this at room temperature. The acclimation requires a room temperature between 50-90 degrees Fahrenheit. Keep in mind that cold paint flows slowly, which means there is no need for thinning.
1. Pre-Mix the Paint
The first step requires you to mix the latex paint. The solid ingredients in the latex paint usually build-up at the bottom of the can over time. So, the mandatory step is to mix the paint. Use the power drill to chuck the mixer. It allows you to mix the paint accurately.
To test whether or not you have adequately mixed the paint, you need to run the wood stick through the latex. Check whether the stick drags at the can’s bottom. If yes, it means you haven’t mixed the solids thoroughly. In such a situation, you can run the power mixer again and continue until you mix the paint.
2. Check the paint thinning
Before you fully mix or thin the latex paint, it is a good idea to check whether or not the paint really needs thinning. Use a paint sprayer to check the viscosity of the latex. Through the viscosity, you can determine whether or not the paint needs further thinning.
You can likewise use a viscosity cup that helps you measure viscosity. Dip some latex paint in a disposal cup and then pour the paint through a kitchen funnel. If the latex clogs the exit hole of the funnel, you need to thin it.
3. Remove Impurities & measure water
Thinning the water can’t restore the developed film and paint chunks. So, you need to remove the large pieces using the hook end of the can opener. The next step is to remove any remaining large pieces and other sorts of impurities using a mesh cone strainer.
You need to add the right amount of water. For this, you must use a measuring cup that can correctly gauge the water. Don’t use a dry measuring cup. You must add the amount of water depending on the paint consistency or the required viscosity.
In general, experts recommend adding 4 ounces of clean water. It is a good way to start. Yes, you can add water later if you need to. Paint companies cap the quantity of water at 8 ounces. This amount is required per gallon of paint, especially for spray paint applications.
4. Add water into the Latex paint
Adding water into the latex paint is an important step, which requires you to pour and mix water slowly into the latex. Typically, you need to gently stir the paint using the wood paint stick. Again, you need to use the funnel or viscosity cup to test the paint before use.
Painting experts suggest to go slow and add water carefully. It is because there is no room of mistake and it is a one-way procedure. Again, we must say that you can add some more water if you need to thin the latex further. Remember, you can’t make the paint thick again. So, always act carefully and create a balanced mixture.
5. Test the thinned paint
The final step is to test the thinned paint. You may see some bubbles while using the paint mixer vigorously. So, roll out or brush the thin paint on a surface that you want to paint. If you think the paint is good, start your DIY painting project. Otherwise, consult the instruction manual and find out how much more water you need to thin the latex paint.

Never use petroleum-based products to thin water-based latex paint. Adding water to paint dilutes the paint and thus lightens its color, so additional coats may be necessary to improve the color quality.
