Detailed Explanation
- Moisture Check: Before starting, ensure the concrete is completely dry. Moisture can hinder proper paint adhesion, causing premature peeling and bubbling.
- Removing Old Paint: Old, peeling paint should be removed with a paint scraper or a chemical stripper to ensure new paint has a smooth surface to adhere to.
- Repairing Damages: Any cracks, holes or imperfections should be filled in using a concrete filler for a smooth, even surface.
- Cleaning: Use a pressure washer to remove any dirt, grime, or mildew. Stubborn stains can be removed with appropriate cleaning solutions.
- Masking Off: Use painters tape around any edges you don't want to paint to provide a nice, clean finish.
- Priming: Applying a coat of concrete primer before painting is important for better adhesion and an even finish.
- Painting the Perimeter: Start by painting around the edges, then fill in the main area to ensure even coverage.
Following these steps, you will be able to successfully paint existing concrete with long lasting results.
