619 StarKrete Urethane

619 StarKrete Urethane

Urethane Concrete


The 619 system is a seamless cementitious urethane flooring system for industrial and heavy commercial environments. Application methods vary between slurry, troweling, and self-leveling broadcast options, all using the same base resin material. Simply change the quantity of sand in your mix. This flexibility allows the installer to stock one resin for multiple types of applications, minimizing waste and the need to stock multiple products.

What Makes Us Unique

Our 619 Urethane System allows for the installer to mix their own additives and sand. With other products, all the necessary sands/powder/dye/etc. is pre bagged. If the installer where to reduce the quantity of premix to attain a thinner mix, vital ingredients would be removed such as dyes, leveling agents, outgas prevention, etc. Our product allows the installer to change the sand mix, and not remove or reduce the vital ingredients necessary to properly install the flooring system.

Mixing and Application Instructions

Surface Preparation

Concrete surface should be clean and free from previous coatings. Scarification is recommended. Remove previous patchwork if any failures are observed. Scarification should remove any patchwork not properly installed. Remove any contaminates and standing water. Ensure surface is dry prior to application.

Product Mixing

We recommend working in 1 or 2 gallon mixes, however experienced installers may work in larger batches. Mix ratio is 1:1, Plus 1 KretePac, and one dye pack per gallon. Aggregate should be 20-30 mesh sand or color quartz, at 10-30lbs, depending on your desired application consistency. Add 10lbs for self-leveling, and 20lbs for a slurry. Adding more will allow the formations of coves, and ramps.
Sample recipe for slurry: ½ gallon A, ½ gallon B, One KretePac, One Dye pack, 20lbs of sand.
Sample recipe for self-leveling: ½ gallon A, ½ gallon B, One KretePac, One Dye pack, 10lbs of sand.

Product Application

619 is generally applied at a thickness of 1/8in to 1/2in. However, up to 3” can be applied. Apply with surface and air temperatures above 35 degrees Fahrenheit. Thinning is not required or recommended. The mixed material can be applied by squeegee, gauge rake, or trowel. Maintain temperatures within the recommended ranges during the application and curing process. It is best to maintain a wet edge over the entire application area. Direct sunlight, sudden temperature changes, or high temperatures may cause outgassing or bubbles.


Use Keytone Solvents

Recoat or Top coating

Multiple coats of this product are acceptable. If you opt to recoat this product, you must first be sure the previous coat is fully cured. Always remember that colder temperatures will require more cure time for the product before recoating can commence. Before recoating or top coating, check the coating to ensure no contaminants exist. If a blush or contaminants are present on a previous coat, remove with a standard detergent cleaner. Allow 24 hours to topcoat with urethane or epoxy sealer.


Restrict the use of the floor to light traffic and non-harsh chemicals until the coating is fully cured (see technical data under full cure). It is best to let the floor remain dry for the full cure cycle.
