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 Polyaspartic 80 is 1 to 1. That is, one part of A - resin, to one part of B - hardener. Generally, one mixed gallon is ideal for application. Mix the following with a drill and jiffler mixer.
- Pre-mix part A for about 30 seconds. Pour out 1/2 gallon of part A into an empty mixing bucket.
- Add 1/2 gallon of part B and mix for 1 minute until homogeneous. Be careful to scrape sides of bucket to insure that no unmixed material remains.
- Immediately apply to the floor. Polyaspartic 80 in mass has a short pot life. Once poured out on the floor, 10-15 minutes of working time can generally be expected.
Application Process
Polyaspartic 80 is generally applied as the final top-coat. For estimation purposes, use coverage rates of 200-250 S/F per gallon for light textured finishes and 150-200 S/F per gallon over a smooth surface. Refer to other Onyx data sheets for application of base systems that the Polyaspartic 80 will be applied over. As a general rule polyurethanes/ polyaspartics should not be applied directly to concrete. Use an epoxy primer for best adhesion.
- 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.
- Only if needed, you may thin material by adding 1 pint of acetone per gallon of Polyaspartic 80
- Apply by immediately pouring out on surface in a ribbon, while walking and pouring.
- Using a window squeegee on a pole, pull the coating evenly over substrate.
- Using a 3/8” non-shedding phenolic (plastic) core paint roller,roll coating forwards and backwards.
- Lastly, backroll in the opposite direction from step 5. Roll the floor in one continuous step without stopping and do not go back and touch up.
NOTE: Polyaspartic 80 cures quickly so you need to move fast and keep a wet edge. Pot life is limited so keep mixed volumes small until you become comfortable working with the material. Do not over roll which causes the material to tack up.
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
Polyaspartic 80 while in an unreacted state may be cleaned up with acetone.
