The best way to seal paint tins involves cleaning the rim, using a proper tool for resealing, and taking preventative measures to maintain the paint's quality.
Here's a breakdown of how to effectively seal paint tins:
1. Clean the Rim:
- Remove Excess Paint: Before attempting to close the lid, thoroughly clean any dried or wet paint from the rim of the tin and the underside of the lid. This prevents a poor seal and makes future opening easier. A scraper or rag works well.
2. Reseal Properly:
- Use a Specialist Tool: Opt for a specialist paint can opener that is designed to carefully lift the lid without bending it out of shape. These tools also typically have a blunt end that can be used for resealing.
- Gentle Application: Place the lid back on the tin, ensuring it's aligned correctly.
- Secure the Lid: Use a rubber mallet or the blunt end of the specialist paint can opener to gently tap around the entire circumference of the lid. This ensures a snug and airtight seal. Avoid using a metal hammer, as it can damage the lid and tin.
3. Preventative Measures:
- Cling Film Barrier (Optional): Before replacing the lid, consider covering the opening of the tin with a layer of cling film. This acts as an extra barrier, preventing skin formation on the paint's surface and minimizing the risk of dust or dirt contaminating the paint.
- Invert the Can (Optional): After properly sealing, some people invert the paint can for a short period. This can help to create an airtight seal, but be absolutely certain the lid is secure first to prevent a messy spill.
4. Storage Conditions:
- Cool, Dry Place: Store the sealed paint tin in a cool, dry place away from direct sunlight and extreme temperatures. This helps to prolong the paint's shelf life.
- Avoid Freezing: Protect the paint from freezing temperatures, as this can permanently damage the paint's composition.
By following these steps, you can effectively seal paint tins, preserving the quality of your paint and preventing it from drying out.
