What You'll Learn
Thinning with water
Thinning Valspar Expressions Exterior Paint & Primer with water is a straightforward process, but it requires careful attention to ensure the best results. Here is a detailed guide on how to do it:
Firstly, it is essential to determine if your Valspar Expressions paint is water-based or oil-based. This is crucial because thinning procedures differ between the two types. Water-based paints can be thinned with water, while oil-based paints require the addition of mineral spirits or a manufacturer-recommended thinner.
Once you have confirmed that your paint is water-based, you can start the thinning process. Begin by carefully reading the label on the paint can. The label often provides specific thinning instructions, including the recommended ratio of paint to water. For example, it may suggest a ratio of three parts paint to one part water. Following the manufacturer's instructions is essential to achieve the desired consistency and maintain the paint's performance.
If no specific instructions are provided, a general guideline is to add a small amount of clean water at a time. For Valspar Medallion, for instance, a maximum of 8 ounces of water per gallon of paint is recommended, but this can vary depending on the specific paint type. It is important to gradually add the water while stirring to avoid over-thinning, which can affect the paint's coverage and adhesion.
After adding water, thoroughly stir the mixture to ensure even blending. To check if the paint has reached the desired consistency, you can perform a funnel test. Pour the thinned paint into a funnel, and if it flows freely through it, the paint is sufficiently thinned. Alternatively, some sprayers come with a DIN cup that can be used to measure the viscosity of the paint. Aim for a viscosity below DIN 50 for optimal spraying.
Before proceeding with painting, it is crucial to test the thinned paint. This can be done by test spraying on a sample surface to ensure a smooth flow without clogging. By conducting this test, you can make necessary adjustments to the paint consistency and ensure that it sprays evenly.
It is important to note that thinning paint with water can alter its colour, making it appear lighter. This may result in a final colour that differs from the sample patches or digital renderings. Therefore, it is advisable to conduct test sprays on small areas to ensure the colour meets your expectations.

Ratios of paint and thinner
Valspar Exterior Paint can be thinned with water or mineral spirits/acetone. The ratio of paint to thinner depends on the type of application and the desired thickness of the paint.
For airless spray applications, Valspar recommends thinning the paint with up to 8 ounces of water per gallon of paint. This is done to reduce the viscosity of the paint so that it can be sprayed effectively. It is important to note that thinning the paint will also lighten the colour, so it may differ from the original sample patches or digital renderings.
For other application methods, such as roller or brush, a thinner paint may not be required. However, if the paint is too thick, it can be thinned by adding water or mineral spirits/acetone in small amounts. A general ratio of 3 parts paint to 1 part thinner can be used, but it is important to add the thinner gradually and mix thoroughly to achieve the desired consistency.
When thinning with water, it is recommended to start with around 10% thinner and adjust as needed. The paint should be mixed thoroughly, and its thickness can be checked by running it through a funnel. If it flows freely through the funnel, the paint is thin enough.
It is important to note that Valspar Duramax paints cannot be thinned. Always refer to the manufacturer's instructions and recommendations before thinning any paint to ensure the best results and avoid any potential issues.

Stirring the mixture
To thin Valspar Expressions Exterior Paint and Primer, you will need to add a thinning agent to the paint mixture. The thinning agent used depends on the type of paint. For water-based paint, add a small amount of clean water. For oil-based paint, add a small amount of mineral spirits.
- Start by adding the thinning agent gradually to the paint. For water-based paint, add about 8 ounces of water per gallon of paint. You can also use a ratio of 3 parts paint to 1 part thinner.
- Use a stir stick or a drill with a mixing paddle attachment to mix the paint and thinning agent. Mix slowly at first to avoid splashing, then increase the speed to ensure thorough mixing.
- Continue stirring for several minutes until the thinning agent is completely incorporated. Make sure to scrape the sides and bottom of the container to ensure all the paint is mixed.
- Check the consistency of the paint by running it through a funnel. If it flows freely and smoothly, the paint is likely thin enough.
- If the paint is still too thick, add more thinning agent in small increments, stirring well after each addition.
- Once the desired consistency is achieved, test the mixture by spray painting a small area or using a DIN cup to measure viscosity. Aim for a viscosity below DIN 50 for optimal spraying.
- Remember that thinning the paint too much can affect its coverage and adhesion, so always add the thinning agent gradually and test frequently.
- Stir the paint occasionally during use, especially if it has been sitting for a while, to prevent the thinner and paint from separating.
By following these steps and stirring the mixture thoroughly, you will achieve a consistent and properly thinned paint ready for application.

Temperature considerations
Temperature plays a crucial role when thinning and applying Valspar Expressions Exterior Paint and Primer. Deviating from the recommended temperature range can impact the drying and curing process, as well as the overall quality of the paint job.
Firstly, it is important to note that Valspar Expressions Exterior Paint and Primer is best applied when temperatures are between 50°F and 90°F (10°C and 32°C). Applying paint outside of this temperature range can affect the drying time and the final outcome. At lower temperatures, the paint may struggle to dry thoroughly, resulting in a sticky or tacky finish. Similarly, extremely hot temperatures can hinder the drying process. Therefore, it is advisable to monitor the temperature and ensure it falls within the recommended range before commencing painting.
For Valspar Duramax Exterior Paint and Primer, the temperature guidelines are slightly different. This product can be applied at temperatures as low as 35°F, allowing for a longer painting season. However, it is important to ensure that temperatures do not drop below 35°F within 48 hours of application. Additionally, it is recommended to avoid painting if heavy dew or precipitation is expected within the next 12 hours.
When thinning Valspar Expressions Exterior Paint and Primer, temperature considerations may also come into play. While specific guidelines are not provided, it is generally advisable to thin paint in a controlled environment with moderate temperatures. This helps ensure the paint mixture is stable and that the thinning process is effective.
Furthermore, temperature can impact the viscosity and flow of the paint. In colder temperatures, the paint may thicken, requiring additional thinning. Conversely, in hotter temperatures, the paint may become thinner and require less or no thinning at all. Therefore, it is important to assess the temperature conditions and adjust the thinning process accordingly.
Lastly, when thinning Valspar Expressions Exterior Paint and Primer, it is important to consider the drying time and temperature requirements for the subsequent coats. As mentioned earlier, the paint requires a temperature range of 50°F to 90°F for proper drying and curing. If the temperature drops below this range, the recoating and fully cured times may be extended. Therefore, it is crucial to plan the painting project accordingly, taking into account the temperature requirements for each stage of the process.
