How to Make New Paint Match Old Paint?

Matching new paint to old paint requires careful attention to ensure a seamless finish. Here's a breakdown of how to achieve the best possible match:

Key Considerations for Paint Matching

Several factors influence how well new paint matches old paint. Addressing these will greatly improve your chances of success.

• Age and Exposure: Old paint fades and changes color over time due to UV exposure, dirt, and general wear and tear.
• Sheen: The sheen level (matte, eggshell, satin, semi-gloss, gloss) affects how light reflects off the surface, influencing perceived color.
• Application Technique: How the paint is applied (brush, roller, spray) can impact the final color appearance.
• Number of Coats: The number of coats applied affects the overall color depth.

Steps to Achieve a Good Paint Match

1. Obtain a Sample of the Old Paint:

   • The best way to get an accurate match is to take a sample of the existing paint to a paint store.
   • You can chip off a small piece (about 1 square inch) from an inconspicuous area or remove a painted item like a light switch cover.
   • Many paint stores can scan the sample to determine the exact color formula.

2. Consider Fading and Aging:

   • Inform the paint store that the sample is from an older paint job.
   • They can adjust the formula to compensate for fading, which will typically involve adding a small amount of tint to the new paint.

3. Match the Sheen:

   • Identify the sheen of the old paint. This is crucial for a seamless match.
   • Use the same sheen for the new paint. If unsure, bring a sample of the old paint so the paint store can determine the sheen.

4. Test the Paint:

   • Before painting the entire area, test the new paint in an inconspicuous spot.
   • Allow the test area to dry completely to see the true color.
   • Apply two coats to the test area, as the number of coats affects the color.

5. Prepare the Surface:

   • Clean the area to be painted thoroughly.
   • Remove any dirt, grease, or mildew.
   • Sand the surface lightly to create a smooth base for the new paint.

6. Proper Application:

   • Use the same application method as the original paint job (brush, roller, or spray).
   • Apply thin, even coats.
   • Allow each coat to dry completely before applying the next.

7. Blending Techniques:

   • Feather the edges of the new paint into the old paint to create a smooth transition.
   • Consider painting an entire wall or section to avoid noticeable patches.

8. Address Stored Paint Viscosity:

   • Dilute the paint by 5 to 10 percent with water for latex-based paint or mineral spirits for oil-based paint. According to provided reference, stored paints can lose moisture, making it more difficult for touch-ups to match the original coat.
   • This will help ensure the new paint blends seamlessly with the old paint.

Troubleshooting Mismatches

If the new paint still doesn't match perfectly, consider these solutions:

• Tinting: Take the new paint back to the store and have them adjust the tint further.
• Blending: Feather the edges more carefully to minimize the contrast.
• Repainting: As a last resort, repaint the entire surface to ensure a uniform color.
