 GENERAL
 Stampcrete System is cast-in-place concrete, integrally colored and stamped with U.S. patented platform/texturing tools to produce a surface similar to natural stone, brick, slate and other natural paving materials. Base color is achieved through integral color pigments in the concrete mix or surface treated with color hardeners. A powdered color release agent is used in the stamping process and insures maximum surface detail while providing a second color for surface highlights and distinctive grout line look. Stampcrete’s special acrylic base sealer added in the curing process provides full color depth and richness with maximum concrete protection.

GUIDELINES
 Highly trained ACI Stampcrete contractors perform all work. All work shall meet ASTM C 94 and ACI 332 requirements for placement of concrete surfaces. This includes sub-grade preparation and forming concrete. When the concrete truck arrives, add specified Stampcrete color together with Stampcrete reinforcing fibers. Mix integral color and fi bers thoroughly in concrete truck prior to placement. The concrete is then placed at a thickness of 4" (10 cm) or 6" (15 cm) for heavier uses, screed, bull floated, and edged before applying clear or colored release agent on the surface. Release agent is applied evenly over the entire surface before stamping the surface. While in the plastic state, place stamping tools onto the surface and start stamping by using tamper to get the desired texture. Remove excess release agent and saw cut all control cuts 1/3 the thickness of slab, within 12 hours. When surface is dry, apply two coats of Stampcrete clear acrylic sealer to protect surface from fading or staining due to nature’s elements.

 CONCRETE MIX DESIGN
 In freeze-thaw areas, the concrete mix design shall be a minimum of 3,500 psi (24.5mpa), compressive strength shall be 3,500 psi (24.5mpa) at 28 days +. Portland Cement shall meet the requirements of ASTM-C 150. Cement content shall be 564 lbs./yd. (335 kg/m3), 1 bag fiber/yd (1 fiber bag/m3). Add Color as specified. Slump 4 inch + 1 inch (80/100mm), maxi mum water-cement ratio shall be .44 by weight. Coarse aggregate shall be in accordance with ASTM C 33 size 3/4" minus aggregate (14mm). Air-Entrainment 7% (+/- 1%) while using Integral Color, or 3% (+/- 1%) using Color Hardeners. In non-freeze areas the concrete mix design shall be a minimum 3,000 psi (24.5mpa), compressive strength shall be 3,000 psi (24.5mpa) at 28 days +. Portland Cement shall meet the requirements of ASTM-C 150. Cement content shall be 517 lbs./yd. (280 kg/m3), 1 bag fiber/yd. (1 bag fiber/m3). Add Color as specified. Slump 4 inch + 1 inch (80/100mm), maximum water-cement ratio shall be .44 by weight. Coarse aggregate shall be in accordance with ASTM C 33 size 3/4" minus ag gregate (14mm), Air-Entrainment 7% (+/- 1%) while using Integral Color, or 3% (+/- 1%) using Color Hardeners.
