This top-to-bottom (well, really bottom-to-top) overlay recipe is great for putting down a distinctive design, such as this swordfish.

Ingredients
SCP Veneer-Crete Stamp Overlay System (Pewter, with Charcoal Powder Release Agent)
Stampmaster Vegas Seamless Stone texture mats
SCP Chrome Etch acid stains (Cool Blue, Citrus Green, Storm Green, Rust Brown)
SCP Stone Shade dyes (Neon Blue, Pine Green)
SCP Stencil-Crete grout (White) SCP Chrome-Seal 30% sealer (Clear) Ammonia or baking soda

Instructions
- Prep existing concrete surface for overlayment (clean surface thoroughly and repair cracks and spalling if needed, honoring existing control joints).

- Apply thin polymer-modified SCP bond coat material.

- Apply precolored Pewter SCP Veneer-Crete Stamp Overlayment at 1/4-inch depth.

- Apply layer of SCP Charcoal Powder Release Agent (may be broadcast or brushed).

- Place Stampmaster Vegas Seamless Stone texture skins on surface and tamp texture into surface of Veneer-Crete.

- Allow materials to cure out overnight. Wash surface. A pressure washer can be used to wash excess SCP Charcoal Powder Release Agent off surface. Then, wash down to desired amount of Charcoal highlight.

- Honor existing control joints in concrete by cutting through overlayment to reopen them. Place new control joints if needed by cutting through depth of overlayment and one-third the depth of the concrete slab.

- Allow recommended cure time on material prior to applying SCP Chrome Etch acid stain. (The time will vary depending on material and material thickness. Roughly 1/4-inch of SCP Veneer-Crete needs five days at moderate temperatures.)

- Score concentric circles to create outside border using a saw cart or an Engrave-a-Crete Mongoose with circle attachment. Score 1/4-inch deep.

- Draw the fish design inside the border using pencils. (This can be freehand drawing, projected down and traced, or you can use a template.)

- Score design into surface (1/4-inch deep) using a small handheld side grinder with a diamond blade.

- Using sponge brushes, work SCP Chrome Etch acid stains into surface using small circular motions. Scored lines work as color separation guides. (For larger areas, you can spray Chrome Etch acid stain onto the surface.)

- For this design, Storm Green was used on the circle border, Cool Blue was used on the background (highlighted with Rust Brown in areas), and Citrus Green was used on the fish.

- Let stains stand overnight. c Neutralize the next day by applying a solution of 1 quart of ammonia in 5 gallons of water to the surface. As an alternative, mix 1 pound of baking soda into 5 gallons of water. Work into surface with soft bristled broom and flush with clean water. Allow to dry.

- Roll (or spray) a coat of Chrome Seal 30%.

- To add some final depth to the color, use sponge brushes to apply Stone Shades to the desired areas, dry-ragging to bleed edges and achieve the desired amount of shade. Allow to cure. For this design, both Neon Blue Stone Shade and Pine Green Stone Shade colors were applied to the fish.

- Apply SCP precolored Stencil Crete Grout into the scored lines and allow to cure. Clean off excess grout residue.

- Roll (or spray) second, final coat of Chrome Seal 30%.
