Concrete Stamp Mix - 50 lb bag

Avoid the massive expense, mess, and hassle of tearing out old, worn concrete. Stone Edge Surfaces Stamp Mix is the industry’s premier professional-grade stamped concrete overlay, engineered to effortlessly restore and beautify existing concrete surfaces. Whether you are a decorative concrete contractor creating a high-end commercial walkway or a DIYer upgrading a backyard patio, this high-performance, single-component mix delivers a flawless, realistic canvas for stamping or hand-carving stone, brick, wood, slate, and tile patterns.

What sets this polymer-modified concrete resurfacer apart is its incredibly user-friendly "just-add-water" formulation and highly versatile application. Capable of being applied from 1/8” to 1/2” thick on horizontal slabs—and easily adapted for vertical concrete carving and faux rock wall construction—it offers an exceptionally generous 2 to 6 hours of open working time. Designed to yield a commercial-grade strength of up to 5,000 PSI, it provides superior resistance to harsh weather, heavy freeze-thaw cycles, and high foot traffic, making it the ultimate wear-resistant solution for interior and exterior decorative concrete projects.

Features & Benefits

• Just Add Water: No complicated polymer liquid additives to measure. A single-component mix that saves you time and reduces mixing mistakes on site.
• Extra-Long Working Time: Enjoy a generous 2 to 6 hours of stamping and carving time (dependent on temperature and thickness).
• Sharp, Well-Defined Impressions: Formulated with fine aggregates to perfectly replicate the finest details of your stamping tools or texture skins.
• Excellent Bond Strength: Can be applied directly over concrete, brick, block, tile, and even prepared painted surfaces (for extreme adhesion, we recommend priming with Primer 100 first).
• ASTM E84 Class A Certified: Rated for superior fire and smoke safety, making it fully approved for both residential and commercial applications.

What to know before you get started:

• Substrate Prep is Key: Ensure your concrete base is completely clean, solid, and free of dust, oil, or sealers.
• Always Use a Primer: For the ultimate mechanical bond, apply Primer 100 to the surface before laying down your Stamp Mix.
• Coloring Your Mix: You can easily integrally color the mix during the blending process using our Colorpax liquid pigments, or wait to stain the hardened surface later with acid or water-based concrete stains.
• Temperatures Matter: For best results, apply when temperatures are consistently between 50°F and 90°F, and ensure no rain is forecasted for 48 hours after application.
