Stamp Overlay Concrete Resurfacing in Hutto, TX

Inspection

Concrete resurfacing contractors inspect the slab first

An overlay is only as good as what it's glued to. This is the walk-around we do before quoting.

Look over a slab the way we would

Move the loupe over the slab. Keyboard: focus the drawing, then use the arrow keys or Next spot.

Worn, dusty surface. Overlay candidate Paste worn off the top, aggregate showing, chalky to the touch. The slab underneath is fine. This is what overlays are for.

Worn, dusty surfaceOverlay candidate: Paste worn off the top, aggregate showing, chalky to the touch. The slab underneath is fine. This is what overlays are for.
Old paint or sealerRemove first: An overlay bonds to concrete, not to paint. Paint and old sealers get ground off before anything goes down.
Stable hairline cracksOverlay with prep: Fine cracks that aren't moving get routed and filled first. Expect them to show through eventually if they open even a little.
Joint that has to stayKeep the joint: Control and expansion joints are carried up through the overlay. Bridge a joint and the overlay cracks right over it.
Step across a crackNot a candidate: One side higher than the other means the base is moving. An overlay will crack in the same place; this section needs repair or replacement first.
Hollow-sounding patchCut out first: Tap it with a hammer: a dull, hollow sound means it has delaminated. Loose material comes out before an overlay goes on.

Decision

Overlay or replace: sort the slab

Six real situations. Put each where you'd put it, then check our call.

The rule underneath all six: overlays fix surfaces, not soil. On Hutto's Blackland clay, a slab that is still riding the shrink-swell cycle will crack an overlay along the same lines it cracks itself.

If your slab ends up in the right-hand bin, the repair or driveway replacement pages are the next stop.

Overlay, repair first, or replace?

Tap a card, then tap the bin you would put it in. Mouse users can drag.

Our call: Overlay it. The textbook overlay job: clean, profile, overlay. Nothing underneath needs fixing.
Our call: Repair first. Rout and fill the cracks, then overlay. Tell people they may telegraph through in time.
Our call: Replace it. That panel lost its soil. Replace it (and fix the downspout that caused it) before anything decorative goes on top.
Our call: Repair first. Strip the paint to bare concrete first; then it's a good overlay candidate.
Our call: Replace it. Moving concrete cracks any overlay. Deal with the root and replace the panels.
Our call: Overlay it. Solid, stable, just worn: a thin overlay or a stamped overlay renews it without tear-out.

Systems

What concrete overlay contractors put down

Three families of overlay cover most residential jobs.

All three are polymer-modified cement mixes bonded to cleaned, profiled concrete. What differs is thickness and finish. Whichever one goes down, the job runs in the same order, and most peeling overlays skipped or swapped a step.

Stamped overlay (stamp overlay concrete)

The thickest of the three, placed and then stamped with the same mats used on new stamped concrete: slate, stone, plank. Base color, release color and a sealer, as on a full stamped slab; the stamped and decorative page covers pattern and color choices.
Spray texture (knockdown)

A thin coat sprayed and troweled into a textured, cooler-looking surface. Common on pool decks and patios; often scored into tiles.
Microtopping

The thinnest: troweled in coats for a smooth, modern surface. Best under a cover or indoors; slick if sealed glossy outdoors.
What all three need

Bare, clean, profiled concrete; joints carried through; and a sealer suited to sun and foot traffic. Skip any of those and the overlay peels.

Put a stamped overlay job in order

Move the steps with the arrows until the order looks right to you, then check it against ours.

1 Tap and look: is the slab sound?

Our step 1. Hollow spots, steps across cracks and panels that rock decide whether there is an overlay job at all. Everything after this assumes the answer was yes.
2 Grind off paint and old sealer

Our step 2. An overlay bonds to concrete, not to coatings. Grinding (or shot-blasting) also roughens the surface so the new layer has something to grip.
3 Cut out loose patches, fill stable cracks

Our step 3. Repairs go in before the overlay so they sit under it. Doing them after means patching a finished decorative surface.
4 Mark every joint line

Our step 4. The joints disappear under fresh overlay. Marking them on the walls and forms first is how they get cut back in at exactly the right place.
5 Place and stamp the overlay

Our step 5. Primer or bond coat if the system calls for it, then the overlay, stamped while it can still take the mats. In summer this starts early in the day, before the slab heats up.
6 Cut the joints back in

Our step 6. A joint bridged by the overlay cracks it right along the old line. Cutting through to the old joint lets the slab keep moving where it was meant to.
7 Wash off release, seal, keep traffic off

Our step 7. Excess release powder comes off once it has set, then the sealer goes on. Feet and cars wait for the times on the data sheet.

The product's data sheet sets primers, thickness and wait times; this is the order around them.

Field notes: driveways

Concrete resurfacing: driveway overlays that hold on clay

Tires, heat and joints are what an overlay on a driveway has to survive.

Concrete driveway resurfacing contractors get one question more than any other: will it last? On a driveway it lasts when three things are true. The slab underneath has stopped moving. The joints are carried up through the overlay, not bridged. And the product is one its maker rates for vehicle traffic.

Summer adds its own rule. Thin overlays dry fast, and a surface baking in a 96°F August afternoon dries faster than the product wants. We place overlays early in the day in summer, the same as full pours.

Hiring

Choosing between concrete resurfacing companies

Four questions that separate a lasting overlay from a peeling one.

How will you prepare the surface?

The answer should involve grinding or shot-blasting to bare concrete, not just pressure washing.
What happens to the joints?

They should be honored: cut back in or carried through. "We'll cover them" is the wrong answer.
Which cracks will show through?

An honest contractor names the ones they expect to reflect, instead of promising a perfect surface.
What product, and is it rated for this use?

Ask for the name and data sheet, especially for driveways and pool decks.

We'd rather lose an overlay job than sell one on a slab that's still moving. If ours is the quote that says "repair first," that's why.

Cost

Stamped overlay cost factors

The stamped concrete overlay cost is mostly prep and labor.

Grinding and crack repair first

Grinding off paint and old sealer, opening the surface, repairing cracks and spalls. The more prep, the less the overlay saves versus replacement.

Overlay system

Stamped overlays take more material and crew than spray texture or microtopping.

Pattern and color

As with full stamping: mats, base and release color, and borders.

Sealer

Every overlay gets one; pool decks and steps add grit.

Overlay area, steps and edges

Small areas cost more per foot; steps, edges and thresholds take hand work.

Questions

Overlay questions

How thick is a stamped overlay?

Under an inch for the overlay systems we use; the product's data sheet sets the exact range. That is much thinner than a new slab. That's why it can go over existing concrete at doors and garage thresholds without making a big step, and why the slab underneath has to be sound.

Will my cracks come back through the overlay?

Yes, if they are still moving. Stable hairlines that were filled may stay hidden for years; moving cracks reflect through quickly. We tell you which ones we expect to show.

Can you overlay a driveway?

Yes, with the right product and a sound slab. Tires and turning loads are harder on an overlay than feet are, so driveways get a mix rated for traffic and no overlay on the approach in the City right-of-way unless the City approves it.

Is an overlay cheaper than replacing?

Yes, usually, because there's no tear-out, haul-off or new base. It stops being cheaper when the slab needs so much repair first that you are paying for both.

How long until I can walk and drive on it?

1 day for foot traffic on most systems, longer for vehicles, and the sealer adds its own wait. The product's data sheet decides; we give you the dates in writing.
