Estimate Pigment, Hardener, Tint Coverage & Coloring Cost
Use this Concrete Color Calculator to estimate integral pigment dosage, dry-shake color hardener quantity, tinted sealer coverage, and decorative concrete coloring cost. It is designed for patios, driveways, walkways, floors, pool decks and other colored-concrete projects.

A Concrete Color Calculator helps estimate the quantity of coloring materials used in decorative concrete. Different color systems are measured differently. Integral pigments are often dosed as a percentage of cementitious-material weight. Dry-shake color hardeners are usually estimated by pounds per square foot or pounds per 100 square feet. Tinted sealers are calculated from surface area, number of coats and product coverage.
Because those systems work differently, a useful calculator should not force every project into one formula. This page separates the most common approaches so you can enter the rate published for the exact product you intend to use.
Pigment is mixed throughout the concrete rather than applied only at the surface.
Dry-shake material is applied at the surface for color and wear resistance.
Color is carried in or added to a coating applied over cured concrete.
Compare pigment, hardener, release, sealer and contingency costs.
For integral color systems that specify dosage as a percentage of cementitious-material weight, the calculation is:
Use the cementitious content and pigment dosage approved for the actual mix.
For example, 5 yd³ of concrete with 600 lb of cementitious material per cubic yard contains 3,000 lb of binder. At a 4% pigment dosage, the estimated pigment requirement is 120 lb before any optional material allowance.
Concrete pigments vary in formulation, color strength, packaging and recommended dosage. A percentage that creates a light tan with one pigment may create a much deeper shade with another. Some systems are supplied as premeasured bags designed for a specific amount of concrete, while others are proportioned directly by cementitious weight.
For that reason, the calculator leaves the dosage field editable. Enter the manufacturer's rate from the color chart, technical data sheet or supplier. Do not assume that a generic 2%, 4% or 6% value is universally appropriate.
A printed or digital concrete color chart is only a reference. The actual slab can look different because the finished color is influenced by many variables:
A site mock-up is especially useful for architectural or high-visibility concrete where the owner expects a specific appearance.
Swatches above are decorative examples only and are not tied to any manufacturer color name.
Dry-shake color hardener is commonly used with stamped concrete and other decorative flatwork. Unlike integral color, the material is concentrated at the surface. Product coverage is often stated as pounds per square foot or pounds per 100 square feet.
Application rates can vary substantially with color, traffic, substrate color and product system. Lighter colors may require more material for opacity, and heavily trafficked surfaces may use different application guidance. Follow the actual data sheet.
Tinted sealers can refresh existing decorative concrete, deepen color or add a translucent tone to a surface. Coverage is controlled by surface area, number of coats and the product's square-feet-per-gallon rating.
Highly porous, textured or weathered concrete can consume more sealer than smooth dense concrete. Prior coatings may also reduce or change absorption, so compatibility and adhesion should be checked before application.
Patios often use integral color, color hardener, release color and sealer together to create stamped or textured decorative finishes. The calculator can estimate each material separately so the project budget stays transparent.
Driveway color systems need to account for traffic, deicing exposure where relevant, maintenance and sealer compatibility. Surface-applied materials should be chosen for the expected service conditions.
Walkways are ideal for color accents and smaller decorative sections. If you still need the concrete quantity, calculate geometry first with the Concrete Walkway Calculator, then use that volume or area here.
Assume a colored patio requires 6 yd³ of concrete. The mix contains 580 lb of cementitious material per cubic yard, and the selected pigment system calls for 3% of binder weight.
If the supplier provides premeasured color bags for each yard of concrete, use the supplier's bag-per-yard instructions instead of this percentage method.
Suppose a stamped-concrete area is 1,200 ft² and the manufacturer recommends 60 lb of color hardener per 100 ft².
Even when pigment dosage is identical, two concrete mixtures may not look the same. Cement color, SCM content, aggregate fines, water content and air content can shift the background tone. Ready-mix consistency matters from truck to truck, especially on large pours where adjacent sections will be viewed together.
For architectural concrete, coordinate color with the concrete producer before placement and avoid unapproved water additions at the jobsite. Changes in water can alter both surface appearance and concrete performance.
Curing can affect final color uniformity. Uneven moisture loss, plastic sheeting marks, curing compounds or early drying can create visible variation. The curing method should be compatible with the decorative system.
Sealers can darken or enrich color, especially solvent-based or “wet look” products. Always test the sealer on a sample or inconspicuous area when appearance matters. For quantity planning, use the separate Concrete Sealer Quantity Calculator.
Decorative color cost is more than pigment alone. Depending on the system, the material budget may include:
The cost mode lets you combine these values into a single project budget and optionally calculate cost per square foot.
Some systems base dosage on total cementitious weight, while others are supplied by bag per cubic yard. Use the product instructions.
Screen colors cannot reproduce every real concrete finish. Use physical samples and mock-ups when color accuracy matters.
If dosage is based on cementitious content, confirm exactly which binder materials the pigment supplier includes in the calculation.
Uncontrolled water additions can contribute to visible color variation and performance changes.
Light colors, traffic level and product system can require different coverage rates.
Sealant chemistry and gloss level can noticeably change color depth and appearance.
Stains, sealers, hardeners and curing compounds should be compatible with one another.
For concrete materials, finishing and construction guidance, review technical resources from the American Concrete Institute (ACI). For information related to pigments and decorative concrete color systems, also follow the technical data provided by the specific pigment, hardener, stain or sealer manufacturer selected for the project.
This Concrete Color Calculator is a quantity and budgeting tool. It does not guarantee a final color match, replace a mock-up, approve a mix-design change or override manufacturer application limits.
