SPEC MIX® Masonry Mortar is a dry, preblended mortar mix containing Portland cement, hydrated lime and dried masonry sand formulated for superior bond, water retention and board life.
What is Type S mortar mix used for?
Ideal for laying brick, block, and stone in load-bearing walls for above- or below-grade applications. Ideal for building walls, planters, chimneys, and for tuck pointing or repairing existing mortar joints. Type S mortar can also be used as a stucco for scratch, brown, and finish coat applications.
What is the difference between type S and type in mortar mix?
Usually, a Type S mix has a high compressive strength of between 2,300 and 3,000 psi. Type N mortar mix, which contains one part portland cement, one part lime and six parts sand, is a medium compressive-strength mortar of at least 750 psi and can achieve 28-day strength between 1,500 and 2,400 psi.
What can SPEC MIX be used for?
SPEC MIX IWR mortar is specially formulated to reduce water penetration, shrinkage and efflorescence of masonry mortar joints and provide superior workability and bond strength for optimal performance.
How do you make Type S mortar?
For Type “S” mortar use a ratio of 1 part cement, 1/2 part lime, 2.25 parts sand. Like type M mortar, use Type “S” for below-grade applications where greater strength is required, and lighter weight projects such as home improvement projects requiring greater mortar strength.
