This technique can add depth and a delicate pattern to an already beautiful floor.
- FLOORmap vinyl stencil: FIG113
- AmeriPolish Solvent-Based Dye: Midnight Black
- Muriatic acid solution, mixed 4 parts water to 1 part acid
- After placing your concrete, grind surface to the point where you’re using 400-grit abrasives.
- Once you’ve finished a pass with the 400-grit pads, clean the surface thoroughly to remove all dust and debris. Let the floor dry completely.
- Apply the FLOORmap stencil design to the surface, following the manufacturer’s instructions to ensure that you have an even, secure transfer of the pattern.
- Mask the area from the edge of the stencil outward with masking tape and plastic sheeting, protecting the surrounding concrete from unwanted etching.
- Using a sprayer, carefully apply the muriatic acid solution to the exposed areas of the stencil pattern.
- Keep the surface evenly wet (reapplying solution, if necessary) for about 10 minutes.
- Once the desired amount of etching has taken place, thoroughly neutralize and power-wash the acid off the surface. Let dry completely.
- Remove the stencil from the surface, and clean the surface of any residual adhesive, dust or debris.
- Apply an even coat of AmeriPolish dye to the surface, and let dry completely.
- Clean any dye residue from the surface before continuing with the polishing process, stepping up your abrasives until you reach the desired level of gloss.
