Specpatch 15 Fast-Setting Polymer-Modified Concrete Repair Material
Fast-Setting Concrete Repair Material for Interior & Exterior Repairs
SpecPatch 15 is a fast-setting, polymer-modified concrete repair mortar designed for repairing concrete floors, walls, sidewalks, curbs, precast concrete, tilt-up panels, masonry surfaces, and other concrete structures. This one-component repair material requires only the addition of water and provides a durable repair that can be feather-edged, shaved, sanded, and shaped to match surrounding concrete. It is suitable for horizontal, vertical, and overhead applications in both interior and exterior environments.
Key Features & Benefits
Fast Setting Formula
SpecPatch 15 develops an initial set in approximately 15 to 30 minutes and reaches final set in about 60 minutes, allowing repairs to be completed quickly and efficiently.
One-Component Application
Simply add clean water and mix. No additional components are required for standard installations.
Can Be Feather-Edged
The material can be feather-edged and shaped after placement, making it ideal for cosmetic and structural concrete repairs.
Excellent Durability & Adhesion
Provides strong adhesion to properly prepared concrete surfaces while delivering long-term durability in demanding environments.
Interior & Exterior Use
Designed for both indoor and outdoor repairs, including freeze-thaw environments.
Concrete Color Finish
Dries to a natural concrete color that blends well with surrounding surfaces.
Common Applications
Sidewalk & Curb Repairs
Ideal for repairing damaged sidewalks, curbs, ramps, and walkways where rapid return to service is required.
Concrete Floor Repairs
Used to repair spalls, surface defects, chips, and damaged areas in commercial and industrial concrete floors.
Precast Concrete Repairs
Excellent for patching precast panels, architectural concrete, tilt-up walls, and concrete products.
Vertical & Overhead Repairs
Its no-slump consistency makes it suitable for vertical and overhead repair applications.
Concrete Pipe & Utility Repairs
Commonly used on concrete pipe systems, drainage structures, and municipal repair projects.
Recommended Surfaces
SpecPatch 15 is designed for use on:
- Concrete floors
- Concrete walls
- Sidewalks
- Curbs
- Tilt-up panels
- Precast concrete
- Concrete pipe
- Masonry surfaces
- Structural concrete repairs
Application Instructions
Surface Preparation
Concrete must be structurally sound and free of:
- Oil
- Grease
- Dust
- Laitance
- Loose materials
- Surface contaminants
For best performance, mechanically prepare the substrate to a minimum CSP 5 profile and maintain a saturated surface dry (SSD) condition prior to application.
Mixing
Mix one 50 lb bag with approximately:
- 6.75 to 7.25 pints of clean water
Mix for 2–3 minutes using a low-speed drill until a uniform consistency is achieved.
Placement
- Trowel firmly into prepared repair area.
- Slightly overfill repair area.
- Shape during placement.
- After initial set, shave and finish to final profile using a steel trowel.
Maximum lift thickness is typically 1 inch per application, with up to 2 inches possible in smaller repair areas. Additional lifts may be applied after the previous lift has set.
Coverage & Yield
Yield Per Bag
- Approximately 0.43 cubic feet per 50 lb bag.
Lift Thickness
- Feather edge to 1 inch per lift
- Up to 2 inches in localized repair areas
Performance Properties
Compressive Strength
- 3 Hours: 1,200 PSI
- 1 Day: 3,100 PSI
- 7 Days: 4,500 PSI
- 28 Days: 6,200 PSI
Flexural Strength
- 650 PSI at 28 days
Slant Shear Bond Strength
- 1,620 PSI at 7 days
Freeze-Thaw Resistance
- 0% scaling loss after 25 cycles
Length Change
- Air Cure: -0.08%
- Water Cure: +0.03%
Shelf Life & Storage
Shelf Life
- 12 months in unopened packaging when stored properly.
Storage Conditions
- Store in a cool, dry location.
- Protect from moisture.
- Keep bags sealed until use.
- Avoid prolonged exposure to direct sunlight.
