Sakrete® Type S Mortar/Stucco Mix is a
preblended mixture of sand and masonry
cement or sand, lime and portland cement.

• Ideal for projects requiring structural strength for brick and block
foundations.

• Applications from 1/4” (6 mm) to 1/2” (12 mm)

• Can be color pigmented with the Sakrete Cement Colors

Use For:

• Laying brick or block

• Scratch and brown coat in stucco applications

• Above and below grade applications

• Masonry parge or finish coating

Technical Data:

Compressive Strength ASTM C270 28 day= >1800 psi
Water Retention >75%

Testing: Mortar should be tested in the field by ASTM C780, standard test
method for preconstruction & construction evaluation for mortar for plain &
reinforced unit masonry. Due to the procedure differences between ASTM C270
& ASTM C780, the compressive strength values resulting from field sampled
mortar are not required nor expected to meet the minimum compressive

strengths of the property specifications of ASTM C270 as tested in controlled
laboratory conditions.

DIVISION 4
Masonry Mortaring – 04 05 13

Color: Gray

Preparation/Application:

For best results all materials should be stored between 400F (40C) and 800F
(270C) 24 hours prior to installation.

Refer to:

- ACI 530.1 Specification for Masonry Structures

- International Masonry Industry All-Weather Council (IMIAC)

• Recommended Practices and Guild Specifications for Cold Weather
Masonry Construction

• Recommended Practices and Guide Specifications for Hot Weather
Masonry Construction

New Construction:

When laying brick or block, construct a sound footing above grade. Consult with
your local building codes before proceeding. For more information visit
Sakrete.com

1. Apply a full bed of mortar onto the base where the brick or block will be
placed.

2. When laying brick or block butter the end with mortar before placing into the
full bed of mortar.

3. Tap into place while leveling.

4. Tool joints once the mortar has set up enough and is thumb print hard.

Tuck Pointing:

1. Place mortar into the joint with a tuck pointing trowel or grout bag.

2. Use the tuck pointing trowel to tool the joint and compact for a tight neat
appearance.

Scratch/Brown/Stucco:

1. Application over masonry must follow ASTM C926 Standard Specification
for Application of Portland Cement Based Plaster.

2. Applications over lath must follow ASTM C1063 Standard Specification for
Installation of Lathing and Furring to receive interior and exterior Portland
cement based plaster.

3. Apply material using a trowel and masonry hawk using enough pressure to
compact the material.

4. Texture stucco to match the surrounding area using a plasterer’s trowel or
finish to desired texture.

NOTE: Check with local building code requirements for proper installation guidelines.

Mixing:

1. Empty contents of Sakrete Type S Mortar/Stucco Mix into a wheelbarrow or
mortar pan forming a crater in the center of the dry mix for the addition of
clean potable water. Projects requiring multiple bags are mixed much easier
with a mechanical mixer.

2. Add clean potable water (see table for water amounts) or enough to
achieve a workable mix. Add additional water if needed. A SOUPY MIX MUST
BE AVOIDED.

3. Excess water reduces strength and durability and can cause cracking,
dusting or scaling.

4. Re-tempering impairs performance.

Curing:

1. Proper curing is critical for sound results. Curing means maintaining proper
moisture and temperature. The material must be kept continuously moist for
several days.

2. In hot or windy conditions keep the mortar/stucco damp to promote
proper curing.

3. Drape plastic over the wall to help retain moisture.

4. If surface begins to appear dry remove the plastic moisten the surface and
replace the plastic.

Can be painted: Using an alkali resistant lime proof paint usually after 7 days of
the stucco application provided the masonry is dry. Contact paint manufacturer
for application recommendations.

Precautions:

Air, mix and substrate temperatures should be between 40°F (4°C) and 90°F
(32°C) and no rain in the forecast within 24 hours of application. For applications
outside this range of temperatures and conditions, contact Sakrete Technical
Service.

• Colder temperatures or higher humidity conditions will retard set times.

• Use only clean mixing container and tools.

• Do not over trowel.

• Do not overwater.

• Do not add any materials other than clean potable water or Sakrete Bonder
and Fortifier. See Technical Data Sheet for mixing instructions.

• Protect from freezing for 24 hours.
