Polyurea 5001 is a two component, ultra high solids, aliphatic polyurea/polyaspartic hybrid.  It is a pigmented material capable of obtaining excellent adhesion to dry, properly prepared concrete.  Polyurea 5001 is a low viscosity, easy to handle product that gives very high gloss finishes that are both hard and abrasion resistant.  The material releases soils easily and has excellent resistance to a broad range of chemicals.  It is a very fast curing material and may be used at temperatures as low as 20ºF, making it ideal for use in cold weather or rapid turnaround projects.
 
Polyurea 5001 was developed as a fast cure primer and finish coat for various protective coating and seamless flooring applications.  Its use as a primer and base coat in color chip flooring allows for the application to be completed in one day, even at lower temperatures.  As a fast curing high performance finish coat, typical uses include automotive repair facilities and clean rooms. As a top coat it can be used in various aggregate-filled epoxy flooring systems.

In this application corner we will be covering the installation of our One Day Granitex Flooring system using both Polyurea 5000 and 5001 coatings. Over the past year this system has become immensely popular. This is due to its ability to save the contractor time and money by reducing the amount of trips to the job and allowing the end user to return the floor to service only 24 hours after the installation is complete.
 
1. Surface prep:  Dry preparation is recommended for this system, so either diamond grinding or shot blasting would be acceptable. If any water is used during surface preparation, the floor should be allowed to dry for 24 hours.

2. Priming:  Polyurea 5001 will serve as your primer in this system. It should be reduced 20% with Acetone. This will allow for the primer to penetrate the concrete resulting in a superior bond. Your coverage on this coat should be 300 - 350 square feet per gallon. This coat will dry in 1 to 2 hours depending on curing conditions. Make sure not to leave any puddles as this can result in slow or incomplete cure.

3. Basecoat:  Polyurea 5001 will act as your basecoat for the chips. Apply the Polyurea at 250-300 square feet per gallon. In order to ensure that the base coat readily accepts the color chips, coat no more than 100 to 200 square feet prior to broadcasting the color chips. This is best suited for a two or three man crew. One person can broadcast while the others continue installing the basecoat. Once the entire floor has been broadcasted it should be allowed to cure for 1 to 2 hours depending on curing conditions.

4. Removal of the chips:  Once the basecoat has cured it is necessary to remove any loose chips. This is best achieved using a blower and push brooms. Chips collected at this stage can be saved and reused on another project. Once the loose chips have been collected it is necessary to scrape the floor down use a 12 inch drywall scraper or sand the floor with 60 grit sand paper on a pole sander. Once this step is complete the floor should be vacuumed to remove all the dust generated by the removal process.

5. Top coat: Polyurea 5000 fast cure will act as your top coat in this system. It should be applied with a flat squeegee or magic trowel and then back rolled to ensure a uniform finish.  Your coverage will be 175-225 square feet per gallon.

6. Special considerations:  These coatings are both very fast curing so do not mix more than can be installed in 30 minutes. Atmospheric moisture acts as an accelerator for both the Polyurea 5000 and 5001, so the coatings will cure slower in dry climates and faster in humid climates.
