COATGUARD 114

SELF-PRIMING EPOXY MASTIC

Coatguard 114 is a high-build, self-priming epoxy mastic midcoat formulated specifically for concrete substrates. Recommended for filling hairline cracks, pinholes, and other surface imperfections, it prepares the surface for optimal topcoat adhesion and finish. Applied after a primer, it enhances system durability by creating a smooth, level, and impact-resistant base layer. This product is mixed with talc powder during application to increase thickness, improve leveling, and ensure deeper penetration into surface voids. Ideal for use in industrial floors and high-traffic environments where mechanical strength and seamless application are critical.

Product Overview

Coatguard 114 Self-Priming Epoxy Mastic Midcoat is designed to serve as a surface corrective layer between the primer and topcoat in epoxy flooring systems. It is not intended for use on metal surfaces and is best applied over properly prepared concrete. With its ability to fill hairline cracks, minor voids, and pinholes, this midcoat improves the base profile and ensures a superior topcoat finish.

Formulated for talc powder integration, it offers excellent build and workability, adapting to a wide range of concrete surface conditions. Its high solids content and bonding characteristics make it essential for heavy-duty flooring systems requiring reliable leveling and strength.

❗LIMITATIONS: Not recommended for concrete less than one month, any unsound substrate, and substrate with moisture content exceeding 3% as per ASTM D4263, non-hardening sealants and caulking, form- release agents containing wax or oil. Silicone-coated surfaces, expansion joint, soluble stains, asphalt surfaces and areas where water seepage exists.

Application Guide

Preparation (After Primer)

  • Ensure the primer is fully cured.

  • Clean the entire area thoroughly.

  • Vacuum to remove all dust, debris, and contaminants from the primed surface before application.

  • The surface must be clean and dry for best adhesion.

Mixing

  • Mix Part A and Part B as per product specifications.

  • Gradually add talc powder while mixing to achieve the desired build and consistency.

  • Use a mechanical mixer until the blend is fully homogeneous.

  • For ease of use, the provided kits are pre-measured for direct mixing:

    • In a 1:1 kit, both cans are half-filled — pour Part B into Part A and mix directly.

    • In a 1:3 kit, the 1-gallon can is filled 2/3 full — pour the quart-sized Part B entirely into it and mix.

Application

  • Apply with a trowel, roller, or squeegee, depending on the required build and leveling.

  • Use a finishing trowel to push material into low spots, pinholes, and cracks.

  • Avoid leaving trowel marks, as they will cause buildup that’s difficult to sand after curing.

  • May be applied in up to 3 coats, depending on substrate roughness and project requirements.

  • This product can also be used to patch surface defects before full midcoat application.

  • Begin application from the farthest point from the exit, working toward the exit to avoid cornering yourself.

  • Mask off baseboards and other protected areas before painting.

  • Maintain a wet edge during application to avoid lap lines or dry joints between passes.
