Installed cost
What this floor costs, built from real quantities
The quantities on this page are derived for the slab on the takeoff page: gallons, kits, machine hours and rental days. The unit prices are yours to enter, because we have no source for what a gallon or an hour costs where you live. The form starts with example prices only so the page can show a worked total; they are not sourced or typical prices, so replace each one with your own.

The line items, with the quantity separated from the price
Read the fourth column. A line marked derived here is a quantity this site worked out from the slab, using the takeoff and preparation assumptions listed on the methodology page. A line marked your figure is a local price we declined to guess at; until you change it, it is the example price in the form.
| Line | Quantity | Cost | Origin | Basis |
|---|---|---|---|---|
| Coating material | 4 kits (9.7 gal ordered) | $760 | derived here | Gallons derived from area, film build and volume solids; kit count derived from the kit size you entered. |
| Decorative flake | 18 lb | $79 | derived here | Broadcast weight derived from area at our assumed partial-broadcast rate. |
| Crack, joint and spall repair material | as measured | $85 | your figure | Volume is derived on the repair page; the price of that volume is yours. |
| Preparation machine rental | 1 day | $130 | derived here | Days derived from the derived preparation hours and your working day; the day rate is yours. |
| Diamond tooling or shot | as quoted | $110 | your figure | Check whether the rental bills tooling or shot apart from the machine; the figure is yours. |
| Preparation labour | 3.4 h | $187 | derived here | Hours derived from area, passes, edge band and access; the hourly rate is yours. |
| Mixing and application labour | 10.3 h | $568 | derived here | Hours derived from area, coat count, broadcast courses and perimeter; the hourly rate is yours. |
What moves the preparation share
At the settings above, preparation is 22% of the total and material is 48%; the rest is application labour. On this bare, sound slab the material is the larger of the two.
Material scales with area and film thickness. Preparation scales with area and thickness and also with what is on the slab: in this site's model a sealer adds a pass, and an old coating or adhesive residue adds two, and each pass repeats the machine hours over the whole floor. Run the same floor with an existing coating to remove and, at the same prices, preparation becomes 38% of a $2,423 total.
That is why the quote check asks what profile a contractor is taking the slab to and how many passes the quote allows for.
The range, and why it is asymmetric
The planning range runs from $1,574 to $2,591, that is 82 to 135 percent of the total. Those widths are our own allowance, not a measured spread. The upside is wider than the downside on purpose: the ways this job gets cheaper are limited, while the ways it gets more expensive are open-ended.
An overrun can come from scope rather than price: a sealer nobody knew about, a crack that opens up when it is chased, or a moisture reading that arrives after the material is bought.
One caution about the per-square-foot figure. It is this total divided by this area, and in this model preparation does not scale with area alone: edge work follows the perimeter, each obstruction adds its own edge, and a rental day is charged whole. So a smaller floor gives a higher figure per square foot. It is a result of this job, not a rate to carry to the next one.
Not in this figure
- Permits, inspections and any structural repair the preparation uncovers.
- Moving what is currently standing on the floor, and storing it somewhere for the duration.
- Heating or dehumidifying the space to bring the slab into the product temperature range.
- Making good on walls, thresholds and door bottoms once the floor is thicker than it was.
- The second attempt if the moisture test was skipped.
Biggest swing factor Material. In this estimate it costs more than the preparation, and it scales with the film build, which this site sets from the traffic and chemical bands (block B2 on the methodology page).
What moves this total, isolated
What actually drives the price up or down runs the same takeoff and preparation calculators on one floor, changing one input at a time, to show how far the existing surface moves preparation hours and how far the finish system moves material.
