How To: Polyaspartic Top Coat

Polyaspartic is commonly used to protect a vinyl flake floor. Whether the floor’s base is epoxy (too hard to be used as a topcoat) or is Polyaspartic (faster than epoxy), the top coat is applied to seal air voids between the flakes, lock them in place, and provide an abrasion and chemical resistant shell. Traditional systems might offer a two step process to achieve what some coatings can do in one. *Testing of the chosen Polyaspartic will determine if the one step application can substitute for the more time consuming two step process.

*It’s important to note that Polyaspartic creates CO2 as it reacts. If this gas is not released before the resin closes at the top, bubbles will be trapped. Some formulas cannot be applied at greater than eight mils, and temperature/humidity can also cause bubbles. It’s recommended that the material supplier be contacted before a single coat is attempted.

The video shows a flake floor that’s been scraped and vacuumed to remove all loose flake. The area size is 156SF and the volume used to achieve full sealing and protection is 1.5 gallons. The WFT thickness will be +/-15 mils (1604/15=106SF per gallon). The application tool is a long-bladed flexible squeegee. This type of squeegee is chosen because it leaves just the right amount of Polyaspartic behind. Tool pressure is enough to flatten the blade, but not so much that it becomes physically difficult to maintain. The floor is then left to fully cure.
