Red Seal Painter and Decorator Practice Exam

When using water-based paints, what is the recommended method for cleaning brushes?

1. Wipe with a dry cloth

2. Rinse thoroughly with water and mild soap

3. Use paint thinner for cleaning

4. Soak in warm water overnight

The correct answer is: Rinse thoroughly with water and mild soap

Rinsing brushes thoroughly with water and mild soap is the recommended method for cleaning water-based paints. This approach effectively removes paint residue from the bristles while minimizing damage to the brush. Water-based paints often have a latex base, which is designed to dissolve in water, making it easy to clean up. By rinsing with water and using a mild soap, you ensure that any remaining paint is completely washed away, helping to maintain the quality and lifespan of the brush. Proper cleaning techniques prevent the bristles from hardening and ensure that the brushes can be used effectively for future projects. Other methods, such as using paint thinner, are not suitable for water-based paints since thinners are typically used for solvent-based products. Soaking brushes can also lead to damage and may not effectively remove the paint. Wiping with a dry cloth does not provide adequate cleaning, as it may just smear the paint rather than remove it completely.
