Step 1:  PREP CONCRETE & PATCH FLOOR

Use a grinder and diamond blade to make any cracks in the concrete floor wider. Don't press too hard - just enough to fit some material into the crack. If you can't fit a playing card into the crack, it doesn't need to be widened because it won't show. Sweep or vacuum any dust before the next step. If your floor is extremely dirty or stained, clean clean it with a heavy-duty outdoor cleaner. Ensure the slab is completely dry before moving to the next step.

Mix equal amounts of Part A and Part B of Floor Patch Epoxy Gel. Mix well until they become one uniform color. Use a stiff putty knife to fill the cracks with just a little more than it needs. The Floor Patch Epoxy Gel will be cured and ready for the next step in 4-8 hours.

Step 2: GRIND

Use a concrete grinder to scratch the concrete slab. Use a hand grinder with a 7" diamond cup wheel for the edges, and a walk-behind floor grinder for the remainder. Connect these tools to a shop vac so there is less dust in the air while grinding. Clean up any remaining dust with either a vacuum, blower, or broom. Make sure you vacuum under the sheetrock and any small spaces. This will help ensure that the moisture seal epoxy primer applies smoothly.

Step 3:  Apply Moisture Seal Primer

Before applying primer, do a moisture test on concrete floors. Tape down a piece of plastic and check back in 24 hours. If the plastic is dry and the concrete hasn't changed colors, you're ready for the next step. If moisture is present, apply Epoxy Undercoat.

Measure 1-2 ounces Moisture Seal Epoxy Primer per square foot of floor to cover. Thoroughly mix part A by itself before mixing in part B at a 2:1 ratio by volume. Moisture Seal Epoxy Primer has become the industry standard when applying epoxy over concrete, creating a tenacious bond to the slab. Mix the material for 2-4 minutes with a paint stick or drill and paddle mixer. Take time to scrape the sides and bottom mid-way through mixing.

Put the Moisture Seal Epoxy Primer into a roller pan for use on the concrete block perimeter of your garage. Use a 1/4'' microfiber roller to spread it evenly and use a small paint brush for hard-to-reach spots. The concrete blocks will soak up the primer, so you should roll on one more thin coat before adding flake.

Spread the mixed moisture seal across the floor in thin lines. The goal is to have a thin and even coat of epoxy primer. Don't let it get too thick in any spots. Use the magic trowel squeegee to spread it out, then use a 1/4'' microfiber roller to roll over it twice, front to back and then side to side. This will give you the best results.
