Mixing wall paint allows for customized colors and efficient use of leftover paint. Success depends on understanding paint types and following proper mixing techniques.
Understanding Paint Types and Mixing Compatibility
Before mixing, ensure all paints are the same type (e.g., latex, acrylic) and intended for the same surface (interior walls). Mixing different types of paint can lead to inconsistent results and poor adhesion. While acrylic paints were originally developed as wall paints, and can be mixed with them [Quora], mixing paints with different sheens (e.g., flat and semi-gloss) may yield unpredictable results [Reddit]. Similarly, mixing interior wall paint with interior wood paint is possible, but achieving a desired color is challenging due to variations in tint [DoItYourself]. Never mix spray paint with interior wall paint [Reddit].
Mixing Techniques for Custom Colors
Mixing your own paint allows for creativity and cost savings.
- Start Small: Begin by mixing small amounts to test the color before committing to a full batch. Gradually add small amounts of one color to another until you achieve your desired shade.
- Use a Clean Container: Employ a clean bucket or container for mixing to avoid contamination.
- Thorough Mixing: Mix thoroughly using a paint stirrer or a drill with a paint mixing attachment. Ensure complete integration of colors to prevent streaking.
- Matching Existing Colors: If you are trying to match an existing color, it's best to bring a sample to a paint store for professional color matching. Mixing paints to exactly duplicate a color is difficult to achieve reliably at home.
- Adding White to Lighten: White paint can be added to lighten a color. Start with small amounts to prevent accidental over-lightening.
- Using Pink and White: As seen in a YouTube video, pink and white can be mixed for a lighter pink shade [YouTube].
- First and Second Coats: For projects requiring multiple coats, you can use one can for the first coat and another for the second, ensuring consistent color [Color Me Thrifty].
Addressing Paint Separation and Storage
- Separated Paint: If paint has separated, stir thoroughly to recombine the pigments and binder. Be cautious of old paint; rust can mix into the paint if the can is old and rusty and will affect the final finish [Reddit].
- Water and Paint: Adding water to paint is generally not recommended for interior wall paint, though a small amount (1 part water to 10 parts paint) can improve the first coat's absorption [Quora]. This is not a standard practice, and its suitability depends on the paint.
- Mixing Leftover Paints: When mixing leftover paints, ensure all the paint is the same type to prevent issues with adhesion and consistency [Salvaged Inspirations].
