Ellisville patios that stay grippy when it rains
An uncoated patio in Ellisville fails in three directions at once. It goes gray in the sun, it grows a slick film in the shade, and it gets dangerous the minute it rains. A UV-stable coating with texture broadcast into it answers all three, which is why the texture conversation matters here more than the color one.
Around Ellisville the patio is rarely the same age as the house it is attached to.
Exterior work is where a crew either knows the weather or learns it the hard way. We have been coating slabs around Jones County since 2021.
The patio was usually poured years after the house
Walk around an older place in town and you will often find three different pours. The front steps, the back patio and the slab under the carport all went down at different times, by different hands, and they wear differently because of it. One is tight and smooth, the next is open and sandy where the surface has weathered off. That is one property with two or three separate grinds in it, and it is why we look at every slab before putting a number on it.
Drainage is the other thing that varies. A patio that sheds water out to the yard behaves nothing like one that holds a puddle against the back wall every time it rains, and the shaded half of a slab under a deep soffit or a line of trees stays damp long after the sunny half has dried. Those damp spots are where the slick green film grows, and they are the first thing we ask about.
Weather decides the day outside in a way it never does in a garage. Humidity already moves cure times in this part of the state, and on an exterior slab a shower at the wrong hour is a real problem rather than an inconvenience. We watch the forecast and we will move a patio date rather than gamble on it.

The order we work a patio in
We read the slab wet
The first thing we want to know is where water goes, so if it has rained recently that is useful rather than annoying. Low spots, the line where a puddle sits and the stretch that stays green all get noted before any tooling comes off the trailer, because they change where the texture needs to be heaviest.
Grinding, and whatever is already on it
Exterior slabs collect sealers. Somebody puts a big box sealer on a patio to stop it looking dusty, it wears off unevenly over a few summers, and what is left is a patchwork. All of it comes off mechanically with the extraction running. A coating laid over half-gone sealer fails exactly where the sealer is still there.
Outside, the decision that matters is texture. Color is what people ask about first.
Edges, steps and the joint at the house
Where the patio meets the house wall and where it meets a step is where water wants to get underneath a coating, so those lines get cut in by hand and carried properly rather than stopped short. Expansion joints are left as joints. Coating straight across one and hoping it holds is how a crack appears in a straight line.
Texture goes in, not on
The grip comes from what is broadcast into the base coat while it is still wet, which is why we decide the texture before we mix anything. Too little and a wet patio is a hazard. Too much and bare feet complain about it. We talk through who uses the space before choosing, then topcoat over the top.
What we find on a patio that has been done before
Exterior concrete gets more cheap fixes thrown at it than any other slab on the property.
Smooth and slick
The most common failure is not peeling. It is a patio coated smooth, with no texture broadcast in it at all, that turns into a slide the first time it rains. It looks superb dry and in a photograph. Nobody tests a patio dry. If the finish has no grip in it, the job was wrong before it started.
A topcoat that was never made for sun
Interior products put outside chalk and fade. The gloss goes flat, the color shifts, and within a season or two the patio looks older than the bare concrete did. The half taking direct afternoon sun goes first, so the fade is usually uneven. An exterior slab needs a topcoat specified for ultraviolet, and that is a different product from the one that goes on a garage floor.
Painted over the algae
Pressure washing a shaded patio makes it look clean for about an hour. The growth is in the pores and a wash does not take it out, so a coating goes down on top of living contamination and lets go in sheets by the following spring. Grinding removes the surface the growth is living in.
No thought given to where water sits
A coating cannot fix a slab that holds water, and anybody who tells you it can has not looked at the low spot. Standing water finds the weakest edge and works at it. Sometimes the right answer involves grinding a fall back into the slab, and sometimes it is a frank conversation about drainage first.
Choosing the texture is the real decision
Color is the question everybody opens with and texture is the one that decides whether you like the patio in two years. A surface built for a shaded walkway that gets rained on wants more grip than a covered porch where people sit barefoot. Chairs dragged across a heavy texture sound rough and scuff their feet. Dogs want something they can turn on without scrambling. None of that is on a chart, so we ask how the space actually gets used.
The chip deck comes out to the house, and outside it earns its keep. A blend that reads warm under a shop light can go flat in open sun. A pale slab in July is bright enough to squint at, and a dark one holds heat long enough that bare feet notice by mid afternoon. You find both of those out by standing on the slab at the hour you actually sit out there.
The other thing you are choosing on an exterior slab is the day. A patio coat going down under a sky that turns is a slab that gets ground back off and done again, so the date moves when the forecast does, and that is a decision we make with you rather than announce to you. If a Saturday matters, say so early. We can build a week around a fixed date. We cannot build one around rain.
Where Ellisville sits for us
Being this close matters more on exterior work than anywhere else, because the weather decides the day and we can move a patio job when the forecast turns.

Questions we get asked
Will it be slippery when it rains?
Not if the texture is right, which is the main thing we specify on an exterior slab. Grip comes from what gets broadcast into the base coat, not from something stirred in at the end. We decide how heavy that texture runs from how the patio gets used.
Will the sun fade it?
Not with the right topcoat. The products that chalk and go flat outside are interior products used in the wrong place, and an exterior slab gets a finish specified for ultraviolet instead. That choice is made at the quote, which is one reason we want to see the slab.
What about the green growth in the shady part?
That comes off with the grinder rather than with a wash. The growth lives in the pores, so pressure washing only cleans what you can see and a coating put over it lets go later. We take that surface off mechanically and prime what is left underneath.
Can you do it if my patio holds water?
We can coat it, but a coating does not change where water goes. Standing water works at the weakest edge it can find. Sometimes the fix is grinding a fall back into the slab, and sometimes drainage needs sorting first. Kevin will say which when he looks at it.
What happens if it rains on the day?
We move it. An exterior coat going down in the wrong conditions is a floor you end up doing twice, so we watch the forecast and reschedule rather than gamble. Being ten minutes from Ellisville helps, because shifting a date is not a wasted trip across the state.
How do I keep it clean outside?
Hose it down and sweep it. A rinse after pollen season or after the mower has been through does most of the work. Pressure washing is fine at sensible pressure, but holding a turbo nozzle in one spot is not. No wax, no sealing, no annual reapplication.
Walk the patio with Kevin
Tell us where the water sits and who uses the space. We will look at the slab, say what the texture needs to be, and bring the chip deck out so you choose it outside.
There are finished jobs in the gallery if you want to see the work first, or tell us about the slab.
