How Overland Park weather affects your epoxy pour
With July highs around 89°F, Overland Park 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 Overland Park 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 Overland Park often climbs above the 65 percent limit, so check a hygrometer before you mix. Lower humidity days give the cleanest finish.
Occasional snow, around 17 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 Overland Park
For most Overland Park 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 Overland Park garage slab
Kansas City area winters bring salt and freeze thaw, and summers are humid. Spring and fall pours go smoothest.
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 Overland Park 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 Overland Park 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 Overland Park 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 Overland Park customers ask
When is the best time to epoxy a garage floor in Overland Park?
For most Overland Park 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 Overland Park?
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 Overland Park?
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 Overland Park 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.
Can I put epoxy over a painted or sealed garage floor?
Not directly. Paint, sealers and old coatings keep the epoxy from bonding to the concrete. Do the water droplet test, and if water beads up, grind the old coating off down to bare concrete before you pour.
Is a quartz epoxy floor slippery when wet?
The quartz sand aggregate gives the surface texture and grip, which is a big part of why people choose it over smooth epoxy or garage floor paint. Slip resistance still depends on how the aggregate is spread and what is on the floor, so wipe up oil and standing water like you would on any floor.
Why does epoxy bubble, and how do I stop it?
Concrete releases trapped air as it warms, and that air rises into the wet coating. Go over each section with a spiked defoaming roller 2 to 3 times while the epoxy is still wet, and pour when the slab is not heating up, such as early morning or evening.
