To paint a stone fireplace, you need to use paint applicators applicable to the job. Paint rollers make excellent priming and painting tools, especially on walls made of rough exteriors such as brick or stone, which can be difficult to cover completely. When painting a smooth surface such as a wall, most roller covers would work. However, with an uneven, rough surface such as stone, a roller cover with a nap of at least one inch is necessary. In addition, use a heavy duty, 5-wire roller frame for maximum strength. Plastic roller frames can bend or break from the extra force you will apply to get paint into all crevices and pores. For brushwork, use professional-grade paintbrushes with wood handles and synthetic bristles. These provide the best results when using latex paint. Purchase different sizes of brushes for the job. Choose a small (1") angled brush for small, tight crevices; a medium-size, angled brush (2") for cutting in; and a large-size brush (3"+) for general painting.
When using a paintbrush, don’t use excess paint to get into pores and crevices. Wiggle the brush up and down and back and forth to push the paint in.
Before painting, apply True Value EasyCare® Ultra Premium Exterior Primer/Sealer. This seals porous surface material so the topcoat won't soak in and dry unevenly. It also helps prevent peeling, rusting and bleed-through. Pour primer into a paint tray and coat your roller. Follow the top-down rule—work from the top to the bottom to get the most even coverage. Use brushes for cutting in and getting into tight spaces. Let the primer dry completely before starting to paint.
When you're ready to paint, pour True Value EasyCare® Ultra Premium Exterior Masonry/Stucco Paint into a paint tray and coat your roller. Again, follow the top-down rule. Use brushes where you can’t use a roller. When you’re done, go over the paint surface with a roller to balance coverage. Use two coats for optimal results.
