Give Your Concrete a Makeover: 4 Quick and Easy Painting Tips for Aggregate Surfaces

Painting aggregate concrete is a great way to give your outdoor surface area a fresh, new look. When properly performed, the painted result provides a decorative space that complements the surrounding landscape. Before you start the job, it is important to bear in mind a few essential tips.

The first step is to clean the concrete surface thoroughly. Prepare a solution of trisodium phosphate (TSP) and water and use this to scrub away dirt, grease, and grime. Rinse the area with plain water from your garden hose using a high-pressure setting, and wipe up any excess water with a mop. Allow the concrete 24 hours to air dry before proceeding with preparation for painting.

The second step is to seal the aggregate concrete before applying a primer. This will protect it from damage from cleaning agents, dirt, and weather. Use an epoxy concrete sealer, applying with a nap roller to ensure an even surface. Allow this to dry fully before applying a primer.

Thirdly, use a suitable primer. An oil-based masonry primer is best for an exterior surface. Use a rough-textured nap roller to coat the entire area. It is important to apply two coats of primer, allowing the first to dry fully before applying the second.

Finally, you’ll need to apply an oil-based masonry paint. Use three to four thin coats, rather than one thick coat, so that the paint adheres better and dries more quickly. Allow at least seven days for the paint to dry before walking on the surface.

In conclusion, with the right preparation, materials, and job execution, you can paint your aggregate concrete with stunning results. Carefully follow the steps outlined here and make sure to practice patience during the drying process for best results.
