How Kansas City weather affects your epoxy pour

With July highs around 89°F, Kansas City summers sit comfortably inside the 41°F to 90°F application range on most days. The ideal cure temperature is 68°F to 77°F, which many Kansas City garages hit naturally from late spring through early fall.

January lows near 21°F mean winter mornings can dip below the 41°F minimum. If you need to pour in the cold months, warm the garage for a day ahead so the slab, not just the air, is at temperature.

Summer humidity in Kansas City often climbs above the 65 percent limit, so check a hygrometer before you mix. Lower humidity days give the cleanest finish.

Occasional snow, around 16 inches in a typical year, still brings some salt and slush into the garage, and a sealed floor makes cleanup easy.

Best time of year to pour in Kansas City

For most Kansas City garages, the most forgiving window is late May through mid September. In that stretch you can usually count on the slab staying between 60°F and 85°F through the 72 hour cure, which gives you full working time and a consistent finish.

Prepping a Kansas City garage slab

Hot humid summers and cold winters bracket a good spring and fall season. Salt and freeze thaw are the main wear factors.

Before anything else, do the water droplet test. Sprinkle water on the bare concrete. If it soaks in within about 30 seconds, the surface is ready to grind and coat. If it beads up, there is a sealer, paint or contamination that has to come off first.

For Kansas City garages that have seen years of salt and freeze thaw, we strongly recommend a primer under the epoxy. It seals porous, weathered concrete and gives the coating a better bond.

Our full step by step process is on the installation instructions page.

Which kit fits your Kansas City project

Indoor quartz sand epoxy self leveling floor kit. This is the kit for garages, workshops, basements and other interior concrete, in Marble Grey, Desert Grey or Black. The quartz aggregate gives a thicker, more textured and more slip resistant surface than standard garage floor paint or thin water based epoxy. It is made for indoor use and does not have strong UV protection, so keep it out of direct, all day sun.

Outdoor washed stone quartz epoxy floor kit. With as much sun as Kansas City gets, patios, walkways and porches should get the outdoor system rather than the indoor kit. It comes in four stone colors and covers up to 100 square feet per kit. The washed stone finish lets water pass through, so it is not a waterproofing membrane. Over a basement or living space, a separate waterproofing layer is needed underneath.

Tools. To spread and finish the coating you need a 22 inch squeegee with pole, a 20 inch defoaming roller and an extension pole for the roller. Our epoxy tool kit adds a tool bag, spiked shoes for walking on the wet coat and five finishing trowels.

How many kits you need

One kit covers 100 square feet at the target thickness of about one eighth inch. No guessing. Measure the length and width of the floor, multiply, divide by 100 and round up. A one car garage is about 200 square feet and takes 2 kits, a two car garage is about 400 square feet and takes 4 kits, and a two and a half car garage is about 500 square feet and takes 5 kits. Do not stretch coverage, since a thin coat will not level properly.

Questions Kansas City customers ask

When is the best time to epoxy a garage floor in Kansas City?

For most Kansas City garages the best window is late May through mid September. You want the garage between 41°F and 90°F, ideally 68°F to 77°F, with humidity under 65 percent.

How much does a DIY epoxy garage floor cost in Kansas City?

One kit covers 100 square feet, so a standard two car garage of 400 square feet takes 4 kits. At current pricing that is $996 in Marble Grey or Desert Grey and $1,200 in Black. If you do not own them, add about $95 for the squeegee, defoaming roller and extension pole, plus primer if your slab needs it. Professional installs are often quoted around $4 to $10 per square foot, which puts the same garage at roughly $1,600 to $4,000.

Can I use the indoor quartz epoxy kit on a patio in Kansas City?

The indoor kit is made for garages, shops and interior floors and does not have strong UV protection, so it can yellow in direct sun. For patios, porches and walkways, use our outdoor washed stone kit. It covers up to 100 square feet per kit, and because the washed stone finish lets water pass through, it is not a waterproofing membrane.

How long before I can park on my new floor?

Light foot traffic is fine after 24 hours, the coating reaches full cure around 72 hours, and you can drive and park on it after about 5 days. In cooler Kansas City garages below 55°F, allow extra time.

Do I need a primer under the epoxy?

Primer is sold separately and is strongly recommended for older or porous concrete, slabs that were painted or sealed, floors with past moisture issues and any garage that sees heavy vehicle traffic. It seals the pores and gives the coating a stronger bond.

Do I have to grind the concrete, or can I acid etch it?

We recommend grinding. An angle grinder with a diamond cup wheel or a rented floor grinder gives the concrete a texture like 60 grit sandpaper that the epoxy can grip. Acid etching is less consistent and can leave residue behind, which is a common cause of peeling.

How do I clean an epoxy garage floor?

Sweep or dust mop to remove grit, then mop with a pH neutral cleaner in warm water. Avoid vinegar, citrus cleaners, bleach and harsh solvents, which can dull the finish over time. Wipe oil and chemical spills right away.

What is hot tire pickup, and how do I avoid it in Kansas City?

Hot tire pickup is when warm tires soften a coating that is too thin or not fully cured and pull it off the floor. Prep the slab properly, apply at the full coverage rate instead of stretching kits, and wait the full 5 days before driving on it.
