How To Thin Acrylic Latex Paint The Right Way
Are you planning on decorating your walls with acrylic latex paint? It is widely used in various DIY projects. You can use it to paint your walls, ceiling, and interior furniture.
If you are working on decorating your walls using this type of paint, you need to make sure that it has the right viscosity. Otherwise, you might end up with an ugly, uneven, and blotchy wall.
During my first DIY wall decorating project, I made the mistake of not checking the paint consistency. As soon as I opened my first can of paint, excitement got the better of me and I immediately brushed fresh paint all over my kitchen wall. It was too late when I realized that the paint was too thick. My kitchen wall looked lumpy and uneven.
This is why I decided to do some research and came up with this practical guide. Here are some easy instructions on how to thin acrylic latex paint successfully.
Here’s what you’ll need:
- Paint (one gallon or one pint)
- Water
- Funnel
- Stirrer or paint stick
- Bucket
Step-by-Step Guide
1. Determine if your paint is too thick or thin.
Once you stir the paint, observe the viscosity of the material. Use a paint stick to stir the paint for at least five minutes and make sure you stir it well enough to mix the particles that are sitting at the bottom of the paint can.
Hold the paint stick and see how the paint drips off it. It should look smooth, heavy, and creamy. Otherwise, if it’s too thick, it can become lumpy. If it’s too thin, it will just drip on the floor.
Another way to check is to pour some paint into the funnel and if it flows seamlessly then the texture is just right. A paint that’s too thick or thin needs thinning. You should test your paint first on a sample material before you start working on your project.
2. Add water to the paint.
After checking the consistency of the paint, you can now add water to thin out the paint. Use three ounces of water for each gallon of paint. Mix the paint and water and check the consistency of the paint. You can add more water as needed until you get the right viscosity.
It is better to start with small quantities of water especially since it’s easier to add if needed. If you use too much water then you won’t be able to undo it. Too much water will ruin the consistency of your paint.
Stir the water and paint in an upward and downward circular movement. Pour the paint from one container to another to properly mix the water and paint. Use a brush to test your paint mixture on a sample material.
When you’re adding water to the paint, do not shake the can. Otherwise, the pressure will create and form bubbles in the paint. The paint and water mixture will prevent the build-up of solid particles on top of the material.
How much water you pour in the paint sometimes depends on the type of paint you have. A high-quality paint is thicker compared to a low-quality paint which has a thin material. A thicker consistency requires more water. In case you are using a pint of paint, add up to two tablespoons of water per pint of paint.
Use a funnel to check the viscosity. Repeat the process of transferring the paint from one can to another bucket using a funnel. Check the consistency of the paint if it is smooth.
3. Test the paint.
Apply the newly thinned paint into a sample material. Use a brush and dip the tip in the paint then brush it evenly over the scrap wood. Make sure it is dry before you apply a second coating. Wait for it to dry off then check the results. The right paint consistency should be smooth.
If the acrylic latex paint still appears too thick, add a half cup of water to one gallon of paint. If it’s still unsuccessful then try adding a thinning additive. This will help condition the paint so that it’s easier to paint without having any brush marks. A commercial thinning additive should be your last resort because a thinning additive can be expensive especially if you compare it to free water.
After successfully thinning your acrylic latex paint and testing it on a sample wood, you can now use it on your decorating project. Keep in mind that you can save more time by doing the mixture properly the first time. At the same time, it is less inexpensive.
Other Useful Tips:
There are some techniques to prevent the paint from turning thick. As soon as you open the can of paint, stir it thoroughly. This makes the paint smoother.
Always keep the cover of the paint can tightly closed after every use. The longer you keep the can open, the more moisture it can cause to evaporate. This contributes to the thickness of the paint.
Do not store let the paint sit in your garage too long. If you haven’t used it for months, the paint will become thick. The particles of the paint will tend to shrink to the bottom of the can.
If you plan on buying a paint thinner, make sure you get one that is compatible with the type of paint you are using. This will help ensure that you get the right quality and texture that you are aiming for. Add the paint thinner in small amounts until you find the right consistency.
