Our take on the Masonry Mortar Cement Type S M 78 lb

This is a 78 lb bag of Type S/M masonry cement — cement only, not a preblended mortar mix. You add 3 parts masonry or general-purpose sand to 1 part cement and water, then use the mortar within 1 hour. It suits brick, block, stone, concrete and clay tile joints at a 3/8 inch thickness. No price was given for this bag, so check the current price against its recent range before buying.

Questions and answers

Is this a ready-to-use mortar mix?
No. It is cement only. You add 3 parts masonry or general-purpose sand and water, then mix to a uniform, lump-free consistency.
How much sand do I add?
Three parts sand to one part cement by volume, plus enough water for a workable mix. Use masonry sand or general-purpose sand.
How long do I have to use it?
About 1 hour after mixing. Discard mortar that has stiffened rather than adding water to revive it.
What can I build with it?
Brick, concrete block, stone, concrete and clay roof tile joints at about 3/8 inch thickness. It is a Type S/M masonry cement for general masonry work.
How much does a 78 lb bag cover?
Coverage depends on joint width and block size, so there is no single figure. At 3/8 inch joints, expect a bag to lay a modest run of block or brick; buy extra for waste.
When is it cheapest?
Masonry cement usually costs least in spring and early summer, before peak building season, and in multi-bag purchases. Compare the per-bag price across stores.
