Mortar Patio Calculator
Calculate the amount of mortar needed for your paver patio project, including cement and sand.
Mortar Patio Calculator - Estimate Cement & Sand for Paver Projects
The Mortar Patio Calculator estimates the amount of mortar, cement, and sand needed for setting pavers and filling joints on mortared patios. Unlike dry-set patios, mortared installations provide a permanent, stable surface ideal for porcelain or thin stone pavers.
For complete patio planning, also use our patio calculator for paver quantities, cost calculator for budgeting, and wall mortar calculator for vertical applications.
Frequently Asked Questions
How much mortar do I need for a patio?
For a mortar bed, plan for 1/2 to 3/4 inch thickness - approximately 1.5-2 cubic feet per 10 square feet. For grouted joints at 3/8 inch wide and 3/4 inch deep, plan for about 1 pound of grout per square foot.
What mortar mix ratio is best for patios?
A standard mortar mix is 1 part cement to 3-4 parts sand by volume. For paver setting, a slightly sandier mix (1:4) provides good workability. For joints, a stronger mix (1:3) improves durability.
Should I use mortar or polymeric sand for patio joints?
Polymeric sand is easier and works well for traditional paver installations. Mortar provides a stronger, more permanent joint ideal for porcelain tiles or thin natural stone that needs solid support.
How thick should a mortar bed for a patio?
A typical mortar bed is 1/2 to 1 inch thick over a concrete base. For setting irregularly thick stone, you may need up to 1.5 inches to level the surface. Thicker beds require stiffer mortar consistency.
How many bags of mortar mix for 100 square feet?
For a 3/4-inch mortar bed, approximately 12-15 bags (60 lb) of premixed mortar covers 100 square feet. For joints only, approximately 3-4 bags cover 100 square feet with standard 3/8-inch joint width.
