Mortar Mix Type S is a preblended mixture of sand and masonry cement or sand, lime and portland cement. For laying brick, block and stone in load bearing walls and below grade applications. Mortar Mix Type S is used to build walls, planters, and chimneys, and for tuck pointing or repairing existing mortar joints. It can also be used for scratch coat, brown coat, and finish of walls. Comes on a returnable pallet, so if you order 15 bags or more at one time we might need to add a pallet charge, which is fully refundable upon return of the empty pallet. We'll be sure to contact you if we need to do so.
