Surface and formwork products

Liquid product coverage

Estimate liquid quantity from the treated area, the exact product’s coverage per application, and the number of equal-rate applications.

Enter your measurements

Example values are prefilled. Replace them with your measurements before using the estimate. JavaScript is required to calculate.

ft²

Enter 0 if there is no area to cover.

ft²/US gal

Use the exact product’s coverage for one coat or application. Enter a value greater than zero, not a rate covering several applications together.

count

Enter how many coats or applications use the same coverage rate.

How it is calculated

Liquid needed (US gal) = surface area / coverage per coat or application × number of equal-rate applications.

Keep the full result when using it in another calculation. Results show up to three decimal places; very small positive results use scientific notation (for example, 1e-6). No extra material for waste is added.

Use the rate for the exact product and application

Measure the area that will actually receive the product. Read the coverage rate for the exact product, surface or form condition, and one coat or application. Coverage is an input, not a universal property of liquid products.

This calculator applies one rate to every counted coat or application. If the product instructions list different rates by coat, surface, or condition, calculate each group with its own rate and add the gallons outside this calculator.

Separate gallons from containers

For 1,500 ft² at an entered rate of 150 ft² per US gallon for one application, the estimate is 1,500 ÷ 150 × 1 = 10 US gal. Two applications at that same rate would require 20 US gal before any separate allowance.

The result is a liquid volume, not a count of cans or pails. Select package sizes and round to whole containers only after you have calculated the total gallons. Confirm surface preparation, compatibility, and application directions on the product label.

Before you use the result

  • The same coverage rate must apply to every counted coat or application. If rates differ, calculate each group separately and add the results.
  • Enter coverage for one coat or application, not a combined multi-application system rate. The calculator does not select a product, coverage rate, or application count.
  • The result is in gallons and does not round up to containers. Check product instructions for surface conditions, compatibility, and application requirements.
Slab & rectangular volume

Estimate the concrete for a rectangular slab, wall, footing, or column using its length, width, and thickness.

Surface evaporation rate

Estimate how quickly water evaporates from the concrete surface using local temperature, humidity, and wind.
