Pro-Poxy™ 204 is a 100% solids, fast setting, two component, high modulus, medium viscosity, moisture tolerant structural epoxy adhesive that meets the requirements of ASTM C-881 and AASHTO M-235. The Pro-Poxy™ 204 is slightly thinner than the Pro-Poxy™ 200.

Recommended uses:

  • The primary use of the Pro-Poxy™ 204 is for bonding fresh concrete to hardened concrete
  • Pro-Poxy™ 204 has excellent adhesion to most construction materials
  • Pro-Poxy™ 204 may be used for anchoring bolts, dowels and reinforcing steel in concrete


  • Meets Specifications: ASTM C-881, AASHTO M-235, Types I, II, IV, V, Grade 2, Classes B & C
  • Mix ratio – 1:1, part A to part B by volume
  • Color (mixed) – Gray
  • Viscosity – 6000 cps
  • Gel time – 15 min. @ 73°F (23°C)
  • Compressive Yield Strength – ASTM D-695: 12,823 psi (88.4 MPa) @ 7 days
  • Concrete Bond Strength – ASTM C-882: 2 days 3450 psi (23.8 MPa); 14 days 4,800 psi (33.1 MPa)
  • Tensile strength – ASTM D-638: 7,280 psi (50.2 MPa)
  • Elongation at break – ASTM D-638: 3.80%
  • Water Absorption – ASTM D-570: 0.61%
  • Attains 80% of ultimate strength in 24 hours, with final cure 7 days @ 73°F (23°C)


  • Pro-Poxy™ 204 has a VOC content of 0 g/L. Compliant with all US VOC regulations including Federal EPA, OTC, LADCO, SCAQMD & CARB.

Estimating Guide

  • Apply Pro-Poxy™ 204 at a thickness of approximately 20 mils [80 sq. ft. /gal., 1.96 sq m /L].


  • The material should be stored at 40° -95°F (5°-35°C). Shelf life of properly stored cartridges is 12 months and 24 months for all other unopened units

Surface Preparation

Surface to be bonded must be clean and sound. Remove oil, dirt, grease, laitance, curing compounds and other foreign matter that may cause a problem with bond. Abrasive blast cleaning and mechanical removal methods are recommended. All drilled holes must be cleaned with a cylindrical bristle brush to remove all loose material. Use clean, oil free, compressed air to blow out any remaining dust or debris prior to installation.


Condition material to 65°-85°F (18°-29°C) before using. Premix each component then place 1 part by volume of Component A and 1 part by volume of component B into a clean pail and mix for three minutes with a low speed drill using a Jiffy mixer or paddle until uniformly blended. Mix only what can be used within the pot life. Air, material, and surface temperatures must be 40°F (5°C) prior to mixing or installation.


As a structural adhesive and for bonding fresh concrete to hardened concrete, apply the Pro-Poxy™ 204 material neat by brush, roller or spray and work into substrate. While Pro-Poxy™ 204 is still tacky, place the fresh concrete.

For anchoring dowels, bolts, reinforcing steel, etc., the depth of the hole should be approximately 9 to15 times the bolt diameter. The space (annulus) around the bolt in the hole should not exceed 1/8 in. (0.3 cm). Always dispense the Pro-Poxy™ 204 into the anchoring hole filling from the bottom up. Insert the bolt, dowel or anchor turning slowly during insertion. After insertion, the hole should be completely full of epoxy.
