Epoxy and urethane sealers are typically polymer solutions that are rolled onto the surface of a concrete slab, giving it excellent abrasion and spill resistance while enhancing the concretes visual appeal. Epoxies and urethanes are much stronger than acrylic sealers, making it a much better choice if you need a surface sealer in a high traffic area. They are frequently used in large retail stores, industrial areas, and warehouse floors; they are even used in most airports.

Application Instructions for the Epoxy Max 100 are as follows:


Surface must be clean, dry, and completely free of loose particles, grease, oil, or any substance that would interfere with proper bond. Moisture content in the concrete should not exceed 6%. Perform vapor testing to verify that the vapor pressure is below 3lb/24hr/ 1000 sq. ft. If moisture vapor transmission exceeds 3lbs, first use Vapor-TekTM 440.

When applying directly to concrete, we recommend either mechanical scarification or acid etching until a suitable profile is achieved (CSP Level 3). If acid is used to clean the concrete, neutralize the surface completely and rinse it with water prior to application. Concrete must be dry for at least 24-48 hours prior to application.

When applying on a newly coated epoxy, be sure to apply within the epoxy recoat window to ensure proper adhesion to the epoxy coating. If applying topcoat outside of the epoxy’s recoat window the surface must be abraded by using 80/100 grit sandpaper, diamond or Diamabrush. Be sure to sand the previous coating until no gloss is visible. Before applying the coating, be sure the sanded surface is clean, dry and free of contaminates such as dirt, dust, or other foreign materials.


Best applied using EPDM Squeegee. 3/8” nap shed-resistant roller is recommended if back-rolling. A paint brush may be appropriate for cutting in or small-scale applications. Spiked shoes, mechanical mixing device also recommended.


Combine two (2) Part A to one (1) Part B, by volume. Kits come pre-packaged and should be used in their entirety and should not be broken down. Do not combine multiple kits when mixing. Once the material is opened, it cannot be re-sealed for later use.

  1. Using a mechanical mixer, mix Part A in original container at low speed for 1 minute. If applicable, pour color additive into Part A and mix for an additional one (1) minute.
  2. Add Part B into Part A and mix on low speed for three (3) minutes or until uniform. Do not combine more material than can be applied within a 10 - 15 minutes timeframe.


Immediately pour entire contents of mixed Epoxy Max™ 100 onto the floor in a long bead approximately 12 - 18 inches wide. Use 1/8” notched squeegee to spread material evenly at 10-30 mils to a uniform thickness.As material is being spread, a second applicator can back-roll material using a 3/8” shed-resistant woven roller. Roll evenly across squeegee passes to minimize application lines. Do not back-roll material once Epoxy MaxTM 100 begins to tack up. This can interfere with self-leveling process. Use a new mixing pail for each kit.


  • Do not apply at a temperature or thickness not recommended.
  • Do not delay in pouring mixed material onto the floor.
  • Do not apply over loose or unsound concrete, asphalt or bitumensubstrates, glazed tile or nonporous brick and tile, magnesite,copper, metal, polyesters, or elastomeric membranes.
  • Moving joints and shrinkage cracks may reflect through system.
  • Joints that are designed to move may reflect through the finishedflooring system if they are not honored.
  • Tire marking may occur.


Clean up mixing and application equipment immediately after use. Use toluene, acetone or xylene; do not use alcohol. Follow solvent manufacturer’s safety instructions. Be sure to follow all local, state and federal regulations when disposing of materials.


Refer to the SDS sheet before use. Safety precautions must be strictly followed during storage, handling, and use. Personal Protective Equipment (PPE) should be worn at all times. PPE will include (but is not limited to): Safety glasses with side shields and high-quality nitrile gloves.


To maintain the appearance and extend the life of the newly sealed surface, it is imperative to have a routine maintenance program. Dirt and debris that is tracked over a finished floor will quickly scratch and dull the surface. Place walk-off mats at entrances. Sweep and mop/scrub floors regularly using soft bristles/pads and a mild cleaner. Some cleaning products and equipment or improper use of these can damage a surface. Remove spills quickly to minimize damage and/or stains. For systems that support parked vehicles or other heavy items on rubber wheels, place a small piece of nonporous material, such as sheet metal or plexiglass between the tires and floor to prevent tire marks. Reapplication may be necessary in heavy traffic areas.


One (1) year when stored indoors at 55°F – 85°F (13°C – 29°C) in a dry location with humidity below 65%. Do not allow materials to freeze.
