SURFACE PREPARATION: The concrete surface must be deemed mechanically and structurally sound, completely clean, and dry. To achieve the above desired results, a mechanical grinding or shot blast method should be performed to an achieve a 50-100 grit profile to insure flatness of the substrate, to remove surface impurities, and to profile the surface of the floor to a CSP-2, as recommended by the ICRI Technical Guideline No. 03732. AVOID USING WATER if possible. If water is used allow 48 hours before coating.

TINTING: Tint with Poly Color pigments. Use 32 oz per 4 gallons of Poly 90. Always add color to Part A and drill mix for 2 minutes prior to adding Part B. Lighter colors such as white may require 32 oz per 2 gallons. Multiple coats may be necessary for total opacity.

MIXING: If mixing less than a full kit, mix Part A & Part B separately with a stir stick, low speed mixer or vigorously shake container prior to blending the smaller kit to ensure uniform distribution of all ingredients. Proper mixing is pertinent to application success. In equal parts (1:1), mix Part A and Part B using a clean, dry mixing container. Drill mix contents approximately 1 – 3 minutes with a paddle mixer. Avoid overmixing or creating a vortex which could introduce moisture content to the mixture. No induction time is required prior to use after mixing. If integrating anti skid media agents, only do so after Parts A & B have been thoroughly mixed. Do Not Thin.

COVERAGE RATE: First Coat : 250 – 300 ft² per gallon* Optional Second Coat : 275 – 325 ft² per gallon* Over Media/Flake : 175 – 225 ft² per gallon* *Coverage rates may vary depending upon surface porosity, texture, application method and prior sealer application. Excessive build up should be avoided.

POT LIFE: Expected workable pot life (in the bucket) after mixing Part A and Part B is approximately 45 – 60 minutes at a common temperature range of 70°F – 80°F at roughly 50% relative humidity. Please note that higher temperatures and high percentages of humidity will shorten pot life, as colder temperatures and lower percentages of humidity will extend the coatings pot life. Product starts to cure quicker once it is applied to the floor.

APPLICATION INSTRUCTIONS: Over smooth surfaces: Using a brush and/or ⅜” nap shedless roller, dip and roll the mixed material from a roller pan. 18” rollers are recommended to speed up application and reduce roller marks. Roll sections at a time backing yourself out of the area and keeping a wet edge. It is recommended to work in sections using control joints as dividers. Large floors can be flat squeegeed and back rolled if desired by the installer. Apply the mixed material within the usable time frame of the pot life. Poly 90 will hang out in the bucket and start to cure quicker once it hits the floor. If the material becomes thick while applying and sticking to the roller, stop applying and discard the mixed material. At this point it has exceeded its usable pot life. Do not allow it to puddle. Use a brush to remove excess coating from joints. Over Flake Systems: Apply the mixed material by pouring directly over flake and spreading with a flat squeegee and backrolling with a ⅜” roller. Apply at approximately 175-225 sq ft per gallon. Do not allow it to puddle. Use a brush to remove excess from joints.

RECOATING: If possible recoat within the suggested recoat window. If recoating outside the suggested recoat window sand using a 60-120 grit sanding screen to ensure adequate adhesion between coats. Vacuum and dry clean thoroughly before recoating. Malish Mal-Grit brushes work well to abrade textured surfaces such as flake systems.
PLEASE NOTE: Applying material outside the suggested parameters may result in product failure. It is always recommended to test the product in a small, inconspicuous area (on the same concrete substrate) for desired results prior to application. Coverage rates may vary for all coatings and substrates depending on porosity, density, texture etc. When applying, do not exceed 400 sq. ft. per gallon. Applying too thin of a coating may cause inadequate film formation or performance expectations may be limited. DO NOT USE ON BRICK. We don’t encourage use outdoors. Increased temperatures will shorten the recoat window. Decreased temperatures will lengthen recoat window.
COF WARNING: The current coefficient of friction required by the ADA is .6 on level surfaces and .8 on ramps. Concrete Floor Supply Recommends the use of slip resistant additives if needed to meet this requirement. It is the installers responsibility to provide a flooring system that meets current safety standards.

Question: What is the best clear coat to use over epoxy flakes on floors?
Answer:Before we answer the question, lets establish that there are 2 types of ‘flake floors’. The first one we call a ‘partial’ broadcast which is where there are flakes every few inches or so and the basecoat is highly visible. The second, is a “full Flake” system which is by far the most popular install done by contractors and pros. This floor has flakes covering 100 percent of the floor. When the flakes are covering the floor you need to use a higher solids coating to properly grout and fill all of the voids that are created by flake. Our Poly 90 is 90 percent solids and has been proven to be a great topcoat in this instance. It also dries quickly to return to service, has a low odor during installation, and is UV stable. This product is highly durable and is in the same family as truck bed liner so you know its tough. We have tons of everyday contractors that use this as part of their everyday business and they just coming back for more due to the ease of installation and the performance it provides for their customers. The Poly 90 can be used on either partial or full flake systems.

Question:What is the best way to apply Poly 90 over flakes?
Answer:Always squeegee and backroll over flake. Squeegee with a flat squeegee with 100 percent coverage as the goal. This properly grouts the flakes and makes sure you don’t get any dry spots. As soon as you squeegee the product out roll it with an 18″ 3/8″ nap roller as soon as possible so the product has the opportunity to lay out before it starts to set. Expect coverages of 150 to 200 sqft per gallon over full flake floors. This product can be put over partial flake floors too with the same methodology (you’ll get slightly better coverage rates)

Question:Can you pigment Poly 90?
Answer:Yes. We have pigments that will make Poly 90 a solid color. One pigment pack (Poly Pigment) will pigment up to 4 gallons of mixed Poly 90

Question: Is Poly 90 best in the bucket while installing or pour on the floor?
Answer: Poly 90 is best left in the bucket. In fact this is one of its great features is that it will hang out in the bucket unlike many Polyaspartics. Pour on the floor, flat squeegee and 3/8″ nap backroll as you go is the methodology. Once on the floor you have 5 to 15 minutes to work with it.

Question: Which pigment will make Poly 90 a solid color?
Answer: We have Poly Pigments
that can be added to make it a solid color. One of our quart size pigments will pigment up to 4 gallons of Poly 90 (or Poly 85 slow)

Question: Can Poly 90 be used as a basecoat?
Answer: Yes. Poly 90 can be used as a basecoat and topcoat. If your using it for a basecoat you need the “Poly” pigment (one does 4 gallons).
