Epoxy Prime Base Fast Plus
Two-Component Deep Penetrating Epoxy Primer
General Product Description
Epoxy Prime Base Fast Plus is a two-component, deep penetrating epoxy primer which provides an excellent bond coat between the concrete substrate and other ONYX high performance coating systems. Epoxy Prime Base Fast Plus has a cure time that is about a quarter (2 hours) of our standard Epoxy Prime Base. Its epoxy chemistry provides excellent bonding characteristics, and its low viscosity allows for deep penetration into a concrete substrate. Because of the porous nature of concrete, Epoxy Prime Base Fast Plus reduces problems associated with outgassing with many coating systems. Epoxy Prime Base Fast Plus is generally applied in 2 ways: 1. As a primer for epoxy, polyurethane and polyaspartic coating systems (thin mils, broadcast, trowel-down etc.) at 350-400 Sq Ft per gallon. Do NOT apply polyaspartic/polyurethane directly over Epoxy Prime Base Fast Plus when installed as a smooth (non-broadcasted) coat. In such cases, apply polyaspartic/polyurethane over Epoxy Prime Base or Epoxy Prime Base Fast.

Packaging
Epoxy Prime Base Fast Plus is available in 2 different kit sizes:
| Part A | Part B | |
|---|---|---|
| 3 Gallon Kit | 2 gal. | 1 gal. |
| 15 Gallon Kit | 10 gal. | 5 gal. |
Surface Preparation
Before the coating is applied, the concrete must be:
- Clean – Contaminants removed
- Profiled – Surface mechanically prepared
- Sound – Cracks repaired
Mechanical methods are required for preparing concrete prior to coating application. Shot-blasting, diamond grinding, scarifying, and scabbling are all acceptable methods. The concrete profile should be a minimum of a CSP 2.
Mixing
The ratio of Epoxy Prime Base Fast Plus is 2 to 1. Due to the quick pot life and limited working time, the experience of the installer will dictate whether to make smaller batches (e.g., 1.5 gal per mix).
- Pre-mix the Part A for 45-60 seconds until uniform. If using the 15 gallon kit, pour out 2 gallons of Part A into an empty, clean mixing bucket. (The 3-gallon kit allows the Part A bucket to be used as the mixing bucket, since the Part A comes in a three and a half gallon bucket.) Use empty, clean buckets when making smaller batches.
- Add 1 gallon of Part B and mix for 60-90 seconds.
- Immediately apply onto the floor. Epoxy Prime Base Fast Plus in mass has a very short pot life. Once poured out onto the floor, 10-15 minutes of working time can generally be expected.
Application Process
Epoxy Prime Base Fast Plus is typically applied in 1 coat. For estimation purposes, use 300 to 400 Sq Ft per gallon as a coverage rate. (Note: For concrete that has been extensively prepared, a much lower coverage rate can be expected. Testing may be required to determine coverage.)
- Always apply in descending temperatures. Concrete is porous and traps air. In ascending temperatures (generally mornings), the air expands and can cause outgassing in the coating. It is safer to apply coatings in the late afternoon, especially for exterior applications. Optimum ambient temperature should be between 65-90°F during application.
- Mix 3 gallons of resin using above mixing instructions.
- Apply by immediately pouring out on surface in a ribbon, while walking and pouring at the same time until bucket is empty.
- Using a window squeegee on a pole, pull Epoxy Prime Base Fast Plus over substrate. If using as a primer, on a thin mil coating, pull resin as thin as possible while still wetting out the concrete and uniformly covering surface. This allows trapped air to escape more easily.
- Using a 3/8″ non-shedding phenolic (plastic) core paint roller, roll the coating forwards and backwards.
- Lastly, backroll in the opposite direction from step 5.
Product Limitations
Always read ONYX PRODUCT LIMITATION GUIDELINES document prior to installation as the content below is only partial information.
Cure times are based on 70-75 °F. Epoxy Prime Base Fast PLUS will cure faster during summer months and slower during winter months. For alternative options, use the regular Epoxy Prime Base or the Epoxy Prime Base Fast accordingly.
Epoxy Prime Base Fast Plus should never be used as a top coat as it will quickly allow for discoloration.
Ground level concrete slabs emit moisture vapor. The allowable vapor emissions for concrete is 3 lbs. per 1,000 Sq Ft over a 24 hour period. If vapor is above this level, then blistering and delamination of the coating may occur. A calcium chloride test, in accordance with ASTM F1869 Standards, should be performed to determine the concrete vapor level. If the vapor levels exceed the 3 lb. limit, a concrete vapor control system should be used before applying any coating system. Please contact the ONYX 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 the coating application. As a general rule, control joints (saw cuts) and random cracks should be saw cut or chased first, then filled with the appropriate patch material. Construction joints (2 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.
Cleanup
Epoxy Prime Base Fast Plus, while in an unreacted state, may be cleaned up with water and degreaser. Isopropyl alcohol, or acetone may be needed once the resin begins hardening.
Warranty
ONYX products are warranted for 1 year after date of manufacture. Please refer to the ONYX Concrete Coating’s Limited Material Warranty for addition clarification. Refer to the ONYX General Product Limitation Guidelines.
