UPC 5400 Standard Epoxy

Product Description

UPC 5400 Standard Epoxy is an advanced, two-component high build epoxy flooring system comprised of 5000-Series Resin and 5400 Standard Hardener. It is designed for use as a base coat or underlayment for leveling substrates. It is generally applied between 1/16” and 1/4” with silica. With the correct amount of silica, it is an excellent dry-pack material for sloping floors for drainage. UPC 5400 is usually used as an underlayment with UPC 5500 series as a final topcoat.

Concrete Preparation

Before coating is applied, concrete must be:

  • Dry – No wet areas
  • Clean – Contaminants removed
  • Profiled – Surface etched
  • Sound – All cracks and spalled areas repaired

Mechanical preparation is the preferred method of preparing concrete for coating application. Shot-blasting, diamond grinding, scarifying and scabbling are all acceptable methods.


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. If a non-UPC patching material is used, contact a UPC technical representative for a compatible and approved alternative.


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, using the proposed method by the assigned applicator to insure proper adhesion and color. A sample area should also be done on any existing coatings to determine if any contaminants exist or if delaminating will occur.


The ratio of UPC 5400 is 2 to 1. That is, two parts A (resin) to one part B (hardener). Generally, three mixed gallons of UPC 5400 at a time is ideal for application. Mix the following with a drill and mixing paddle. Note: If using a drill mixer, use a low speed (not to exceed 300 rpm) to prevent air entrapment.

  1. The Unit 1 kit allows the UPC 5000 Part A container to be used as the complete mixing container. Add entire contents of UPC 5400 Part B and mix for 2-3 minutes.
  2. If using the Bulk 15-Gallon Kit, premix UPC 5000 Part A for 30-45 seconds. Pour out 2 gallons into an empty 5-gallon bucket, which then becomes the mixing bucket.
  3. Add 1 gallon of UPC 5400 Part B and mix for another 2-3 minutes.

Application Instructions

The best method for controlling thickness during application is to map area out first. Determine the layout and square footage of the area, and calculate the required gallons of UPC 5400. Next, mark off on the floor how many gallons of resin are to be used by the time predetermined points have been reached.

  1. Pour mixed UPC 5400 onto concrete.
  2. Trowel or screed-rake the material until resin mix is uniformly applied. If a screed rake is used, trowel away pin marks left by the rake.
  3. Use a 3/8” nap paint roller. Lightly backroll resin, removing any unevenness left by the trowel or screed rake. This generally requires the use of spiked shoes, allowing one to walk in the wet resin mix.
  4. Wait 10-15 minutes while the resin mix self-levels and an even resin surface appears.
  5. Wearing spiked shoes, broadcast silica onto resin until resin is thoroughly covered. This method requires that silica be thrown upward and allowed to gently fall into the resin. Throwing silica directly at the resin mix will result in an uneven finish. Keeping a 1-2 foot wet edge where the next batch will be applied prevents ridges from appearing in the final finish.
  6. Excess silica can be swept up after the floor has cured for at least 6 hours.

Optional Base Coat:

  1. Use UPC 5400 as a base coat for optimal color stability.
  2. Mix per mixing instructions.
  3. Immediately pour on unglazed surface in a ribbon, walking and pouring simultaneously until the bucket is empty.
  4. Using a squeegee on a pole, pull resin tightly and uniformly over the surface.
  5. Using a 3/8” nap paint roller, roll base coat up and backward. Then backroll from left to right.

Vertical Mix

UPC 5400 can be made into a vertical mix by following these steps:

  1. Mix per mixing instructions.
  2. Slowly add Cab-o-sil / Aerosil 200 until mixture reaches desired thickness.


UPC 5400, while in an un-reacted state, may be cleaned up with water and degreaser. Isopropyl alcohol or acetone may be needed once the resin begins hardening. Lastly, a strong solvent like methylene chloride may be required if resin is nearly set up.

Product Limitations

Ground level concrete slabs emit invisible moisture vapor. The allowable moisture emissions for concrete are 3 lbs / 1,000 SF over a 24 hour period. If moisture is above this level, then blistering and delamination of coating may occur. A calcium chloride test should be preformed to determine concrete moisture level. If moisture levels exceed the 3 lb. limit, a concrete moisture vapor control system should be used first before applying coating system. Please contact the UPC technical department for approved systems.

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 Perfect Patch or similar approved hard epoxy product. Construction 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 an elastomeric caulking.


Universal Polymer Coatings products are warranted for one year after date of application. Please refer to the UPC Limited Material warranty for additional clarification.


Consult UPC 5400 material safety data sheet. Avoid UPC 5400 contact with skin. Some individuals may be allergic to epoxy resin. Protective gloves and clothing are recommended.
