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.

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 insure proper adhesion and desired finish.

Mixing

The ratio of UPC 2700 2K-WB Urethane is 3 to 1. That is, three 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 2700 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 2700 Part B to Part A container and mix for 3 minutes.
  • If using the Bulk 4-Gallon Kit, premix UPC 2700 Part A for 30-45 seconds. This will also be the mixing container.
  • Add 1 gallon of UPC 2700 Part B to Part A container and mix for another 3 minutes.
  • Note: If using only a partial bulk kit, it is crucial to ratio the 3:1 material accurately in a clean mixing container, following mixing guidelines.

Top Coat Over Decorative Chip

UPC 2700 2K-WB Urethane is generally installed as a top coat over decorative chip when non-yellowing, low smell, and high chemical resistance is required.

  • 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.
  • Work in manageable sections. Try working from control joint to control joint if possible.
  • Apply approximately 200 SF per gallon by pouring out on surface in a ribbon. Using a squeegee, pull material from wall to wall over substrate while covering surface evenly. *Take care not to puddle or apply over 6 mils as product can turn white if installed too thick.
  • 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 9” or 18” x 3/8” paint roller from wall to wall to perfectly level and smooth surface.
  • Make sure to always CAUTION tape finished work areas; asking all other trades to stay off for 24-hours.
  • In high traffic areas a second coat may be recommended to increase mil thickness.

Top Coat / Sealer Application Instructions

To apply UPC 2700 2K-WB Urethane as a top coat or sealer, begin with application instruction steps 1-5 for top coat over decorative chip.

  • Apply approximately 250-350 SF per gallon by pouring out on surface in a ribbon. Using a squeegee, pull material as thin as possible 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 9” or 18” x 3/8” paint roller from wall to wall to perfectly level and smooth surface.
  • In high traffic areas a second coat may be recommended to increase mil thickness.

Clean-up

UPC 2700 2K-WB Urethane, while in an 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 3 lbs / 1,000 SF over a 24 hour period. Relative Humidity results should be below 85% per ASTM F2170. If moisture is above this level, then blistering and delamination of coating may occur. A calcium chloride test can be preformed to determine concrete moisture level. If moisture levels exceed the 5 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/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 an elastomeric caulking.

Warranty

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

Safety

Consult UPC 2700 2K-WB Urethane safety data sheet. Avoid contact with skin. Some individuals may be allergic to polyisocyanates. Protective eyewear, gloves and clothing are recommended.
