Outdoor concrete takes a beating—cracking, spalling, and deteriorating under exposure to moisture, freeze/thaw cycles, impact, and UV rays. For long-lasting, structurally sound repairs, Epoxy.com Product #10 Epoxy Mortar can be used as both a surface patch and a deep-fill repair system when extended with aggregate. When paired with Product #441 Aliphatic Urethane, the result is a strong, UV-resistant finish that protects your repair for years to come.
🔧 Product #10 – Heavy-Duty Epoxy Mortar Binder
Epoxy.com Product #10 is a 100% solids epoxy resin system designed to be used as a trowel-grade mortar or filled system for repairing damaged concrete.
Key Features:
Bonds tenaciously to old concrete Can be feather-edged or used in thick, deep patches Cures to a high-strength, impact-resistant surface Easy to trowel, with excellent chemical and moisture resistance
🪨 For Deep Patching: Add Aggregate
Begin by mixing Product #10 thoroughly. Gradually add silica sand to achieve the desired consistency. For deeper or bulk-filled applications, pea gravel and crushed stone may be added as needed.
To create a deep-fill repair mortar, extend Product #10 with clean, dry aggregate such as:
Pea gravel Silica sand Crushed stone
This allows you to:
Fill larger voids and holes economically Reduce shrinkage and heat buildup Increase the structural volume of the patch
Typical Mix Ratio:
1 part mixed Product #10 3 to 5 parts by volume of clean, dry aggregate (based on depth and application)
Apply in lifts if filling more than a few inches deep. Use forms if needed to contain the patch while it cures.
☀️ Product #441 – Aliphatic Urethane Topcoat for UV and Weather Protection
Once Product #10 (with or without aggregate) has fully cured, apply Product #441 to finish the repair and protect it from sunlight, chemicals, and abrasion.
Benefits:
UV-stable – resists chalking and yellowing Chemical and stain resistant – excellent for fuel pads, traffic areas, and industrial applications Durable finish – extends the life of your patch Available in a range of colors for visibility and aesthetics
Apply with a roller or airless sprayer. Texture can be added for slip resistance if needed.
✅ Typical Applications
Damaged loading docks Outdoor stair treads or concrete steps Broken curbs and sidewalks Parking lot and apron edge repairs Exposed slab sections or pits.
⚠️ Prep and Application Tips
Always clean and profile the existing concrete (CSP 3–5 recommended) Remove all loose material, dust, oils, or coatings Prime with Product #899 if substrate is porous or damp Mix only as much epoxy as you can use in its working time (larger volumes cure faster)
Conclusion
For deep concrete patching outdoors, Product #10 combined with aggregate gives you the power to rebuild and reinforce damaged areas without compromise. Finished with Product #441 Aliphatic Urethane, your repair stays protected from sun, water, and wear. Together, they create a professional-grade solution for industrial, commercial, and exposed concrete repairs.
