High Plasticity
Provides a highly workable mortar with excellent spread under light trowel pressure and uniform adherence to masonry units. Carries more sand than most masonry cements or mortar cements for better yield without sacrificing workability.
Excellent Water Retentivity
Increases workability and bonding characteristics, reduces segregation of materials, requires less retempering of mortar during use. SUPER LIMOID SA® Mason’s Lime mortar resists suction, even from dry masonry, leaves ample time to strike joints. Makes a mortar particularly suited for hot-weather construction.
Balanced Strength
Permits optimum balance between workability and bond strength; provides adequate compressive and tensile strength to accommodate structural movement, plus elasticity to absorb normal stresses from winds and vibration. Weather Resistance Offers tight, uniform bond to resist water penetratio
Lower Costs
Costs less per mix then most masonry cements or mortar cements, saves up to 30% in cementitious material cost per cu. yd. mortar. Easily mixed, makes a richer mortar that carries more sand, works easier. Masonry units lay up faster with less waste and "shake-up" time for greater on-site production.n, helps prevent efflorescence, leaky walls and frost damage. Self-healing properties of SUPER LIMOID® SA Mason's Lime repair fine cracks for many years after construction.

Mixes
- Type M Mortar, shall be mixed in proportion of one bag Portland Cement, one-quarter bag SUPER LIMOID® SA Mason’s Lime, to not more than 3 3/4 cu. ft. sand (1: 1/4 : 3 3/4).
- Type S Mortar shall be mixed in proportion of one bag Portland Cement, one-half bag SUPER LIMOID® SA Mason’s Lime, to not more than 4 1/2 cu. ft. sand (1: 1/2: 4 1/2).
- Type N Mortar shall be mixed in proportion of one bag Portland Cement, one bag SUPER LIMOID® SA Mason’s Lime, to not more than 6 cu. ft. sand (1: 1: 6).
- Type 0 Mortar shall be mixed in proportion of one bag Portland Cement, 2 bags SUPER LIMOID® SA Mason’s Lime, to not more than 9 cu. ft. sand (1: 2 : 9). Limited exterior use.
Execution
Unit Masonry Preparation
Highly absorbent masonry units shall be wetted (not soaked) before laying.
Mixing
Mortar Proportion ingredients accurately and mix for at least 5 minutes in mechanical batch mixer with enough water to produce a workable consistency.
Mortar Application
Lay mortar in a uniform bed and completely fill joints between masonry units.
- Application
SUPER LIMOID® SA Mason’s Lime is specially formulated to develop high plasticity and excellent water retention. The formulation permits a controlled volume of minute air bubbles to mix with the mortar. This entrained air goes completely through the mix and takes the water with it. The result is a deeply penetrating mortar that handles easily and contributes to better masonry construction at a lower cost.
Regulatory & Compliance
- Compliance
Airentraining SUPER LIMOID® SA Lime complies with ASTM C207, Type SA.

Good Design Practices
- Specifications below are offered as desirable inclusions in any masonry work, but are not intended to be complete.
- Generally, masons consider a 94-lb. bag of Portland Cement and a 50-lb. bag of hydrated lime to each equal one cu. ft. and would add 6 cu. ft. sand to make a 1: 1: 6 mix. Actually, a bag of hydrated lime equals about 1 1/4 cu. ft.
- Environmental Conditions -- Refer to the Masonry Industry Council Publication "Hot & Cold Weather Masonry Construction" (1999)
Safety & Health
- Warning
- May cause eye or skin burns. Harmful if swallowed.
- Contains: hydrated lime (calcium magnesium hydroxide)
- Avoid contact with eyes or skin.
- Do not take internally.
- Avoid breathing lime dust.
- Always wear niosh approved eye goggles when handling lime. In case of eye contact flush eyes thoroughly, including under eyelids, with water for 15 minutes. Call physician immediately.
- Wear protective clothing to prevent skin contact. If skin contact occurs, wash with water. Should skin irritation continue, see physician.
- If swallowed call physician immediately.
- Ventilate or use dust collector to prevent airborne lime dust. If there is airborne lime dust use a NIOSH approved dust respirator.
- Do not use this material on playing fields or children’s play areas.
- Keep out of reach of children.

Delivery and Storage of Materials
All materials shall be delivered in their original unopened packages, containers or bundles, and stored in a place providing protection from damage, deterioration and contamination. Damaged, deteriorated or contaminated materials shall be removed from the premises.
Environmental Conditions
In cold weather, temperature of masonry materials shall be above freezing when placed. Masonry shall be protected from freezing for 48 hrs. after placing. Unless precautions against freezing are taken, masonry shall not be erected when temperature is below 32o F on a rising temperature, or below 40o F on a falling temperature. Masonry shall not be laid on walls or footings that are frozen or contain frost. (See Good Design Practices Note 3 above).
