Epoxy Crack Filler | 100% Solids Gel Crack Repair

Epoxy Crack Filler is a professional grade, 100% solids, two component (1 to 1) gel epoxy designed for repairing cracks, joints, and surface defects in concrete. Its specialized non sag consistency allows for clean application on both horizontal and vertical surfaces, providing excellent control during installation.

This is the ideal solution when you need a clean, controlled repair that stays exactly where you put it without running or settling.

Where This Product Fits in Your System

• Vertical Repairs: Perfect for wall stems, curbs, and vertical cracks where liquid fillers would run.
• Control Joints: Filling joints on floors where you need the material to stay flush with the surface.
• Wall Defects: Patching spalls and imperfections in concrete walls or pillars.
• Pre-Coating Prep: Sealing cracks before applying high build epoxy or polyaspartic systems.

Key Advantages

• Non Sag Gel Formula: Stays in place on vertical surfaces without dripping or sagging.
• 100% Solids and No VOC: Solvent free formulation with virtually no odor during application.
• 1 to 1 Mix Ratio: Simple, equal part mixing for consistency on the jobsite.
• Superior Bond Strength: High mechanical properties designed for industrial and commercial traffic.
• Excellent Compatibility: Engineered to be coated over with any epoxy, urethane, or polyaspartic system.

Why Professional Installers Use It

Unlike liquid repair resins that can disappear into the subgrade or run down a wall, this gel epoxy stays in the "v-groove." This saves you material and labor by eliminating the need for multiple applications. It gives you the time to tool the repair perfectly flush before it sets.

Application Guidelines

• Mixing: Combine Part A and Part B at a 1 to 1 ratio by volume. Mix thoroughly for 3 minutes until a uniform color is achieved.
• Placement: Use a flat putty knife or steel trowel to press the gel into the crack or spall.
• Finishing: Tool the material flush with the surrounding concrete. Once cured, the material can be ground or sanded smooth using a diamond grinder.

Frequently Asked Questions

What makes this different from liquid crack repair?
This is a high viscosity gel. While liquid repairs are designed to soak deep into a crack, this gel is designed to bridge gaps and stay in place on vertical surfaces or wide cracks without running.

Can I use this on walls?
Yes. The non sag formula is specifically engineered for vertical applications like wall stems, curbs, and pillars.

How fast can I coat over it?
Cure times vary by temperature, but once the material is hard to the touch and ground smooth, it is ready for your primer or base coat.

Is this compatible with polyaspartic topcoats?
Yes. Being 100 percent solids epoxy, it is a stable base for almost all epoxy and polyaspartic coating systems.

Can this be sanded or ground?
Yes. Once fully cured, it grinds cleanly without gumming up diamonds, allowing you to create a perfectly seamless transition on the floor.

Is it safe for interior residential use?
Absolutely. It has zero VOCs and very low odor, making it ideal for basements, garages, and commercial interiors.

What is the shelf life?
Under normal storage conditions in unopened containers, the shelf life is typically one year.

Do I need to prime the crack first?
No. This material is designed to bond aggressively to clean, dry, and mechanically profiled concrete without a separate primer.

What tool is best for applying this gel?
A stiff putty knife, a 6 inch broad knife, or a small steel margin trowel works best for pressing the gel into the repair area.

Can I use this for expansion joints?
This is a rigid repair material. For moving expansion joints, we recommend a flexible joint filler; however, for static contraction joints, this gel is an excellent choice.
