Procedure for Simulated Flagstone
- Rocks and grass are moved away from concrete allowing the flagstone to flow over the sides.
- The surface is checked for any grease, oil, and tar which will be removed with a thinner (xyleen).
- All concrete is etched with muriatic acid which will remove dirt and grime, also opening the pours of the concrete for a proper bond.
- All concrete is treated with ammonia; this neutralizes any acid left behind.
- Fill cracks on top of the surface at no charge but concrete may shift so we cannot guarantee the cracks.
- A coat of acrylic additive is rolled on to seal the concrete acting as a primer.
- A thin layer of acrylic aggregate is troweled on the surface to act as another primer and first coat of texture.
- A heavier coat of acrylic aggregate is troweled on to make texture which is between 1/8 and 1/4 inch think.
- As the texture dries, we cut a flagstone pattern, depending on the size of the area will determine the size of the stones.
- Lastly, we clean the work area and let dry overnight.
- Control joints are cut with a diamond blade to open the joint to allow movement in the stress areas.
- All cuts made to be a grout line are sanded with a small grinder to clean up the cuts giving it a more natural look.
- Surface is swept and blown down cleaning area for color.
- The color is sponged on each stone alternating the colors depending on how many colors are chosen. We recommend three colors.
- With clean water we go over the stones once more to clean any heavy spots and blend the color together giving a more natural look.
- A custom grout color is chosen and then brushed on, making the look of grout lines. Also at this time, we caulk along the house if needed and put grout color on the stem wall giving a nice border look.
- After all dried and cleaned up, we brush and roll sealer to protect the surface but not just any sealer. Desert Rose uses polyurethane 250 with UV absorbers and hindered amine light stabilizers which will outlast acrylic sealers by years.
