The Mapei Ultracolor Plus FA Coverage Chart helps installers determine how much grout is needed for floors, walls, kitchen backsplashes, and shower tile installations. While Mapei provides coverage estimates based on a 10-pound bag, all grout sold at Tile Choices is the larger 25-pound bag size. This means you will receive more than double the coverage shown on the standard chart. Below, we explain how to interpret the chart and calculate the correct amount for your project.

Understanding Mapei Ultracolor Plus FA Grout Coverage

Coverage varies based on tile size, grout joint width, and installation thickness. Mapei publishes these values per 10-pound bag for universal comparison. To estimate the coverage for a 25-pound bag, simply multiply the published numbers by 2.5.

Why the Mapei Chart Uses 10 lb Bag Measurements

The 10-pound bag measurement creates a universal standard, making it easier for installers to compare grout lines, tile dimensions, and material output. However, the 10-pound size is less commonly sold through retailers. This is where Tile Choices provides clarity for customers purchasing the full-size 25-pound bags.

How to Convert Coverage to 25 lb Bags

Tile Choices only sells 25-pound bags of Mapei Ultracolor Plus FA. To find your coverage:

  • Take the 10 lb coverage amount provided by Mapei
  • Multiply by 2.5 to determine 25 lb coverage

Example: If a 10 lb bag covers 100 sq. ft., a 25 lb bag covers approximately 250 sq. ft.
