Introduction
As a qualified painter and decorator, I've encountered many situations where a can of paint has developed rust.
Whether it's due to improper storage or an old paint can, you might wonder if you can still use the paint.
In this article, I'll guide you through the process of salvaging paint with rust in it and how to prevent rust from forming in the future.
Quick Summary
If you find rust in your paint, it's possible to salvage it with proper steps: 1) Remove rust particles, 2) Check paint quality, 3) Strain the paint, and 4) Use anti-rust additives. Following these steps will help you save money and achieve a smooth, rust-free finish.
Remove Rust Particles
First, you'll want to remove any visible rust particles from the paint.
This can be done using a spoon, paint stick, or any other suitable tool.
Be careful not to damage the paint can, as puncturing it may cause more problems.
Pro Tip: Use a plastic spoon or tool to remove rust particles, as metal tools can scratch the paint can and cause more rust.
Check Paint Quality
Next, check the quality of the paint. If the paint has separated, mix it thoroughly until it reaches a smooth consistency.
However, if the paint smells bad or has a lumpy texture, it's best to dispose of it and buy a new can of paint.
Strain the Paint
To ensure that you remove all rust particles from the paint, strain it using a paint strainer or a fine-mesh sieve.
Place the strainer over a clean container and pour the paint through it.
This will help separate any remaining rust particles and other debris from the paint.
Use Anti-Rust Additives
If you're concerned about rust affecting the paint's performance, consider adding an anti-rust additive to the paint.
These additives can help protect the painted surface from rust and corrosion, ensuring a long-lasting finish.
Preventing Rust in Paint Cans
To avoid encountering rust in your paint cans in the future, follow these storage tips:
- Store paint cans in a cool, dry place away from direct sunlight and moisture.
- Wipe the paint can's rim and lid clean before sealing it to prevent rust formation.
- Use a rubber mallet to close the paint can lid, avoiding damage to the rim.
- Invert the paint can for a few seconds after sealing to create an airtight seal around the rim.
