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: 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: Is Poly 90 more flexible than epoxy?
Answer: Poly 90 is much more flexible than epoxy allowing it to be more resistant to cracking and a good choice if you need to go over a wood substrate compared to epoxy. Epoxies get really hard, but this also limits their “flex”. Epoxies are generally used for base coats when you need a thicker floor, or the floor has a lot of surface damage.

Question: What is the preferred way to apply Poly 90?
Answer: Most contractors find that if you squeegee before you back roll Poly 90 it will give you a much better finish. We recommend our 24” flat flexible squeegee. Some dip and roll if you’re using it for a base coat, but always squeegee and back roll over flake.

Question: What do you do if you go outside of the recoat window of Poly 90?
Answer: The best way to recoat poly 90 if you are outside of the recoat window is to use a sanding screen. You will need a profile in your existing coating before you apply another coat. Use a 80-120 grit sanding screen. Dry clean the floor by blowing and using micro fibers to ensure any residual dust is off the floor before applying your next coat.
