How Much Mortar for 1000 Bricks?

The short answer: mortar for 1000 bricks

The count splits into two products that people both call mortar. Masonry cement is a bag of cement you mix with your own sand, and the trade rule of thumb is about 7 bags per 1000 standard bricks. Pre-mixed mortar already has the sand blended in, so each bag covers far fewer bricks.

For pre-mixed mortar, plan on about 27 to 28 bags of 80 lb mix per 1000 modular bricks with standard 3/8 inch joints. That figure comes straight from the manufacturer's own coverage rating of 37 bricks laid per bag.

To skip the conversions, enter your brick count and joint size into the mortar calculator and it returns bags for either method along with the sand you need.

How much mortar one brick actually uses

Quikrete, the most cited premix brand, states that one 80 lb bag of Mortar Mix lays about 37 standard modular bricks and yields roughly 0.83 cubic feet of wet mortar. Divide 1000 by 37 and round up: that lands at 27 bags.

Twenty seven bags works out to about 22.4 cubic feet of mortar, close to 0.83 cubic yards, for all 1000 bricks. Add 5 to 10% for waste and tooling losses, which pushes a careful order to about 30 bags.

This assumes a standard 4 by 2.25 by 8 inch modular brick with 3/8 inch bed and head joints, laid in running bond. Thicker joints or oversize brick change the math, covered further down.

Pre-mixed mortar bags by size for 1000 bricks

Bag yield scales with weight, so smaller bags need proportionally more of them to cover the same wall. An 80 lb bag stays the most economical per brick, since you pay less handling and packaging per cubic foot of mortar.

The same yield math applies to concrete block. If your project mixes brick and block, see how many bags of mortar per 100 block for the CMU side of the job.

Masonry cement method: 7 bags plus about 1 ton of sand

Pros mixing their own mortar buy masonry cement instead of premix, since it costs less per brick on a large job. The long standing trade rule is 7 bags of masonry cement per 1000 standard modular bricks.

Sand runs about one cubic yard, close to 1 ton, for every 7 bags of masonry cement. Utility and engineer size brick carry more mortar per unit, so those jobs can need 9 to 13 bags per 1000 bricks instead of 7.

The mix itself matters too: a standard Type N blend is roughly 1 part masonry cement to 3 parts sand by volume. See mortar mix ratio for the exact proportions by type and when to step up to Type S.

Brick size, joint thickness, and what changes the count

Joint thickness moves the number more than most people expect. A 1/2 inch joint uses roughly 25% more mortar than a standard 3/8 inch joint, so a job with thick joints can need 34 to 35 bags of 80 lb premix instead of 27.

Brick size works the other way. Larger units like Norman or utility brick cover more wall area per piece, so a wall needs fewer bricks, but each one still carries a joint on every side, which keeps mortar volume closer to what smaller brick uses.

If you have not counted your bricks yet, the brick calculator turns your wall dimensions into a brick count first, so you can size the mortar from there.

What 1000 bricks of mortar and labor cost in 2026

Materials alone are modest next to labor. A pre-mixed 80 lb bag of Type N or Type S mortar runs about 8 to 10 dollars in 2026, so 27 to 30 bags cost roughly 220 to 300 dollars.

The masonry cement route costs less in bags, about 12 to 15 dollars per 70 lb bag, but adds sand. Seven bags of cement plus a ton of sand lands near 115 to 155 dollars total, before delivery.

Labor is the bigger number. Bricklayers charge roughly 300 to 800 dollars in labor per 1000 bricks, and a three person crew typically lays 400 to 500 bricks a day, so the job takes about 2 to 2.5 working days.
