Concrete Preparation
Before the coating is applied, the concrete must be:
- Clean – Contaminants removed
- Profiled – Surface etched
- Sound – Cracks repaired
Mechanical methods are preferred for preparing concrete prior to coating application. Shot-blasting, diamond grinding, scarifying, and scabbling are all acceptable methods. The concrete profile should approximate 60-80 grit sandpaper after preparation.
Mixing
The ratio of Isourethane CRU is 3 to 1. That is, three parts of A - resin, to one part of B - hardener. Generally, one to two mixed gallons are ideal for application. Mix the following with a drill and jiffy mixer.
- Pre-mix part B for about 30 seconds. Pour out 1 quart of part B into an clean mixing bucket.
- Add three quarts of part A and mix for 1 minute until homo- geneous. Be careful to scrape sides of bucket to insure that no unmixed material remains.
- Unlike epoxies, do not pour out onto floor. Use dip & roll application method.
Application Process
Isourethane CRU is generally applied in one application as the final coat. For estimation purposes, use coverage rates of 300 S/F per gallon for light textured finishes and 350-400 S/F per gallon over a smooth surface. Refer to other Onyx data sheets for application of base systems that the Isourethane CRU will be applied over.
- It is always best to apply in descending temperatures especially for exterior applications. Optimum ambient temperature should be between 50-90°F and 5° above the dew point during application.
- Mix one gallon of resin using above mixing instructions.
- Apply Isourethane CRU with a 3/8” non-shedding phenolic (plastic) core roller cover. Dip a 9” or 18” roller on a pole into the mixed material. Roll the Isourethane CRU forward and backwards. Do not over roll because the material will tack up.
- Isourethane CRU cures quickly so you need to move fast and keep a wet edge.
Product Limitation
Ground level concrete slabs emit moisture vapor. The allowable moisture emissions for concrete is 3 lbs. 1000 S/F over a twenty-four hour period. If moisture is above this level, then blistering and delamination of coating may occur. A calcium chloride test should be performed 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 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 coating ap- plication. As a general rule, control joints (saw cuts) and random cracks should be saw cut or chased first then filled with Epoxy Grout 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.
Cleanup
Isourethane CRU while in an unreacted state may be cleaned up with acetone.
