What it is

What staining & sealing actually is.

Acid or water-based stain driven into the concrete and then sealed, so the colour is in the slab rather than on it. It reads as concrete rather than as a coating, which is the point — and because there is no film to delaminate, it fails gracefully rather than by peeling.

Where we are the right call

  • Patios, entries and walkways that should read as concrete
  • Interior floors wanting colour without a coating film
  • Slabs with character worth showing rather than hiding

Where we will tell you something else

  • Heavily patched slabs — the stain will show every repair
  • Floors needing chemical resistance or a wearing film
  • Anyone wanting a uniform, repeatable colour
Specification

What it is rated for.

Stain typesAcid stain for variegated, mineral colour; water-based for a wider and more predictable palette
Surface preparationGround and cleaned. Existing sealers and coatings removed — stain will not penetrate through them
SealerPenetrating or film-forming depending on exposure; UV-stable products outdoors
Return to serviceFoot traffic 12–24 hrs after the final seal
MaintenanceRe-seal periodically, more often outdoors. The colour itself does not wear off
WarrantyWritten workmanship warranty, terms by system
How a commercial job runs

Four stages, and you know when you get the space back.

Stage 01

Site assessment

We walk the building, test the slab for moisture and dew point, review chemical exposure and agree the shutdown window. You get a written scope, not a number on a card.

On site, no obligation
Stage 02

Preparation

Diamond grinding or shot blasting to profile, crack and joint repair, and HEPA extraction so the rest of the building stays open.

Dust contained · CSP 2–3
Stage 03

Installation

Base coat, broadcast and topcoat, phased by bay or zone. Overnight and weekend work where production cannot stop.

Phased by zone
Stage 04

Return to service

Foot traffic the following morning, vehicles and racking the day after. Cold slabs cure slower and we tell you the real number.

10–14 hrs foot · 24–48 hrs load
Common questions

What people ask about this system.

Will the colour be even?
No, and with acid stain that is the attraction — it reacts with the minerals in the slab, so the result is variegated and specific to your concrete. Water-based stains are more predictable but still read as concrete. If you want uniform colour, a solid-colour coating is the honest recommendation.
How much of my building has to stop?
As little as we can engineer. Almost all of our commercial work is phased — one bay, one zone or one room at a time — so the whole facility is never down at once. We agree the sequence and the hand-back times at the walk-through and put them in the proposal, which means you can plan around a number rather than a promise.
How quickly can we use the floor again?
Foot traffic roughly 10 to 14 hours after the last coat, vehicles, racking and equipment after 24 to 48 hours, both at 70°F. A cold slab is slower and we will tell you the real figure for your building rather than the data-sheet one.
Do you work nights, weekends and shutdowns?
Yes, and on most commercial jobs that is how we prefer to run it. Off-shift work is normal scheduling for us rather than an exception we charge extra to accommodate. Holiday and summer shutdown windows are the easiest of all to plan against.
Can you install in winter?
In a heated interior, year-round — and winter is often the best time to book institutional and municipal work, because the building is quiet and our calendar is not competing with the summer rush. Polyaspartic systems install down to about 30°F with the slab 5°F above dew point. You may see −40°F claimed elsewhere in this industry; it is not supported by any manufacturer data sheet we work from.
The last coating failed. Why would this be different?
Nearly every failure we are called in to replace comes down to one of three things: the slab was acid etched or not prepared at all, nobody tested it for moisture, or the joints were coated over instead of being repaired. We grind or shot blast to a measured profile, we test and record moisture and dew point before anything goes down, and we treat joints as a separate detail.
What does a site assessment involve?
About an hour on site. We test the slab for moisture, look at the joints, the drains and the thresholds, ask what gets spilled on the floor and what cleans it, and talk through when the space can realistically be released. You get a written scope with a system recommendation and a phasing plan. There is no obligation and no pressure to decide on the spot.
Next step

Let us come and measure it.

We look at the slab, test it for moisture, and give you a real figure for your floor rather than a price per square foot over the phone. No obligation.
