Great! I’ve been frustrated all day about that. Now I’m happy again. Thank you! : )

This was a light to medium flake application, correct? If so, the amount of clear coat is correct. Polyurethane does not go down thick, nor does it need to be. It has a very high abrasion rating which translates to long wear. The flakes that are standing will get knocked down with traffic and should not be very noticeable. Our recommendation is to leave the floor as is and use it. You can always degloss the surface with light sanding and apply another coat at some future date if you feel it needs it.

Just one 1.5 gallon top coat and I applied all of it. I had compared 3 manufacturers and all of them provide 1.5 gal top coat to cover larger size than my 450 sqft garage. The one I used is https://armorpoxy.com/products/armorultra-military-grade-topcoat-3-sizes-1-5-3-15-gallon-kits/. The description says it can cover 525 – 600 sqft. Do I need to apply another coat? The shipment takes about 3 days and tomorrow is the Independence day. So the best chance I can get another kit is the end of this week and the recoat window will be far passed.

How much top coat do you have left?

Hi Arthur. You can’t mask it off since the flakes are tossed when the coating is still wet. This allows the flakes to sink in and the coating take hold. What you can do, however, is cut a piece of cardboard to the size you need to block the flakes. Stick a few toothpicks in it for legs so that the cardboard is only 1/2″ at most off the ground. Once the coating is applied and you are ready to toss flakes in that section, place the cardboard with the toothpick feet over the area. Toss the flakes as normal (high into the air to fall down naturally), then remove the cardboard immediately after. The coating will fill in the tiny depressions from the toothpicks as it does with spiked shoes.
