Packaging
UPC 2500 Water-Based Epoxy is available in 3 different kit sizes:
Part A | Part B | |
Unit 1 Kit | Pre-measured | Pre-measured |
2.5 Gallon Kit | 2 Gallons | 1/2 Gallon |
5 Gallon Bulk Kit | 4 Gallons | 1 Gallon |
Testing
All surfaces are not the same. It is recommended that a sample area be done before the start of the project. The test should be done on-site to ensure proper adhesion and desired finish.

Concrete Preparation
Before coating is applied, concrete must be:
- Dry – No puddled water
- Clean – Contaminants removed
- Profiled – ICRI-CSP 2-3
- Sound – Cracks and spalled areas repaired and ground
Mechanical preparation is the preferred method of preparing concrete for coating application. Shot-blasting or diamond grinding are recommended to achieve ICRI-CSP (surface profile) 2-3.
Patching
Voids, cracks, and imperfections will be seen in finished coating if the concrete is not patched correctly. Patch concrete with UPC Perfect Patch. After the patching material is cured, diamond grind patch.
Mixing
The ratio of UPC 2500 Water-Based Epoxy is 4 to 1. That is, four parts A (resin) to one part B (hardener). Mix the following with a drill and mixing paddle. Note: Use a low-speed drill (not to exceed 300 rpm) to prevent air entrapment.
- The Unit 1 Kit allows the UPC 2500 Part A container to be used as the complete mixing container. Premix Part A for 30-45 seconds to achieve a uniform mixture.
- Add entire contents of UPC 2500 Part B to Part A container and mix for 2-3 minutes.
- If using the Bulk 5-Gallon Kit, premix UPC 2500 Part A for 30-45 seconds. This will also be the mixing container.
- Add 1 gallon of UPC 2500 Part B to Part A container and mix for another 2-3 minutes.
- Note: If using only a partial bulk kit, it is crucial to ratio the 4:1 material accurately in a clean mixing container, following mixing guidelines.Primer/Sealer Application Instructions
Primer/Sealer Application Instructions
- Tape off work areas to protect from foot traffic during application and drying.
- Optimum ambient temperature should be between 65-90°F during application and 5°F above dew point.
- Mix using the mixing instructions above.
- In higher temperatures and dry environments, pre-wetting the concrete with a pump sprayer will extend working time and prevent flash-drying. Be sure to apply only enough clean water to dampen concrete, and avoid puddles.
- Work in manageable sections. Try working from control joint to control joint if possible.
- Apply approximately 250-400 SF per gallon as primer or 150-250 SF per Gallon as Base Coat, by pouring out on surface in a ribbon. Using a squeegee, pull material thin from wall to wall over substrate while covering surface evenly.
- The second applicator, using spiked shoes and a chip brush, can now cut in corners and edge detail. Then, using a 9” x 3/8” non-shedding paint roller, roll coating forward and backward to further level the material.
- Quickly back roll in the opposite direction, using a 18” x 3/8” paint roller from wall to wall to perfectly level and smooth surface.
Clean-up
UPC 2500 Water-Based Epoxy, while in a un-reacted state, may be cleaned up with water and soap. Acetone may be needed once the resin begins hardening.
Product Limitations
Ground-level concrete slabs emit invisible moisture vapor. The allowable moisture emissions for concrete are 5 lbs. / 1,000 SF over a 24-hour period based on a Calcium Chloride Test. Also, a Relative Humidity (RH) test can be performed to test for moisture vapor. RH testing results should be below 85% per ASTM F2170. If moisture is above this level, then blistering and de-lamination of coating may occur. A calcium chloride or Relative Humidity test should be performed to determine concrete moisture levels. If moisture levels exceed the 85% for RH test or 5lbs. for Calcium Chloride, then a concrete moisture vapor control system should be used first before applying coating system. Recommended system for cases of moisture above acceptable levels is UPC 5200. UPC 5200 Moisture Lock passes F3010 spec based on E96 testing results. Please contact UPC representative for additional details.
Coating systems are susceptible to cracking if the concrete moves or separates below the coating. Hence, joint and crack treatment should be reviewed prior to coating application. As a general rule, control joints (saw cuts) and random cracks should be saw-cut or chased first then filled with UPC 777 Perfect Patch. Construction/cold joints (two slabs which meet and hence move) should be treated. After the coating has been applied and cured, saw cut through the coating over construction joints and apply elastomeric caulking.
Warranty
Universal Polymer Coatings products are warranted for one year after date of purchase. Please refer to the UPC Limited Materials warranty for additional clarification.
Safety
Consult UPC 2500 Water-Based Epoxy Safety Data Sheet. Avoid contact with skin. Some individuals may be allergic to epoxy resin. Protective eyewear, gloves, and clothing are recommended.
