BEST Mortar Cement Type N
PRODUCT DESCRIPTION:
Basic Use:
BEST Mortar Cement Type N is a 鈥済reen鈥? product that meets the requirements of ASTM C-1329.
Composition and Materials:
A blend of portland cement, hydrated lime, high performance pozzolan, and additives.
Bag Weight:
70 pound bags (31.8kg)
TECHNICAL DATA:
Applicable Standards:
ASTM C-1329 for Type N
UBC 21-14
ASTM C-91 for Type N
A. Fineness:
This is determined by wet sieving the mortar cement through a No. 325 mesh sieve.
ASTM C-1329 24% Maximum
UBC 21-14 24% Maximum
BEST Mortar Cement Type N 19.4%
B. Autoclave Expansion:
This test is used to predict the long term durability of the product.
ASTM C-1329 1% Maximum
UBC 21-14 1% Maximum
BEST Mortar Cement Type N 0.06%
C. Time of Setting:
Mortar must remain workable to give masons time to use it and tool joints. But if it fails to firm set within 24 hours, the
number of courses of brick laid per day may be reduced.
Initial Set, Minimum Final Set, Maximum
ASTM C-1329 Not Less Than 120 Minutes (2 Hours) Not More Than 1440 Minutes (24 Hours)
UBC 21-14 Not Less Than 120 Minutes (2 Hours) Not More Than 1440 Minutes (24 Hours)
BEST Mortar Cement Type N 250 Minutes (4 Hours 10 Minutes) 325 Minutes (5 Hours 25 Minutes)
D. Compressive Strength:
Compressive strength is the main criterion for selecting a mortar if holding brick apart is the primary concern. BEST Mortar
Cement Type N exceeds the ASTM standards and continues to gain strength over time.

BEST Mortar Cement Type N 500 psi 900 psi 1500 psi 2200 psi 3000 psi
BEST Mortar Cement Type N
E. Flexural Bond Strength:
Bond strength and extent of bond are the main criteria for selecting a mortar if the ability to bind bricks together is the
primary concern. While extent of bond as a parameter cannot be incorporated into a mortar, workability can be
incorporated. With good workability, a skilled mason can lay brick with full head and bed joints and have a very high
extent of bond. BEST Masonry designs cements to impart impressive bond strength and to be sufficiently workable to
allow a high extent of bond. A positive byproduct of high bond strength and high extent of bond is water resistance, since most
leakage through a brick wall is at the interface between the brick and the mortar or in areas where the mortar was
inadvertently omitted.
ASTM C-1329 Minimum 70 psi
UBC 21-14 Minimum 71 psi
BEST Mortar Cement Type N 78 psi
F. Air Content:
Air content affects workability, yield and strength. Masons want a high air content to increase workability and yield. However,
the higher the air content, the lower the compressive strength and bond strength.
ASTM C-1329 Minimum/Maximum 8/16%
UBC 21-14 Minimum/Maximum 8/16%
Masonry Cement 16-21%
BEST Mortar Cement Type N 12-15%
G. Water Retention:
Mortar is affected by water retention in three ways:
a. The greater the water retention, the longer the mortar remains workable. With a longer working time, the mason does
not have to stop to retemper the mortar. This, in turn, increases efficiency and lowers cost. BEST Mortar Cement
Type N is formulated to remain workable.
b. Ultimate compressive strength and bond strength are reduced with each retempering. BEST Mortar Cement Type N
does not need retempering as often as conventional mortars; therefore, it retains its ultimate strength better.
c. When using brick with a high initial rate of absorption, the brick can dehydrate the mortar before it sets chemically.
This reduces the bond strength and the compressive strength significantly when using a low water retentive mortar.
BEST Mortar Cement Type N has a high water retention, and thus does not dehydrate before chemical hydration
occurs.
ASTM C-1329 Minimum 70%
UBC 21-14 Minimum 70%
BEST Mortar Cement Type N 85% average
H. Water Penetration:
There are no ASTM C-1329 limits for water penetration. Brick walls are built with flashing and weepholes to remove water
from behind the walls, since they are known to leak. From time to time, the flashing is penetrated or the weepholes are plugged,
and this can lead to interior water damage. Brick walls can be tested for water penetration with the ASTM E-514 test
(commonly known as the hurricane test). To pass this test, a wall needs to withstand the equivalent of a 5-inch per hour
rainfall event driven by a 60 mile per hour wind for a period of 4 hours. A third party testing lab performed this test for BEST.
Test Method Conventional Masonry Cement BEST Mortar Cement Type N

E. Air Content:
Air content affects workability, yield and strength. Plasterers want a high air content to increase workability and yield.
However, the higher the air content, the lower the compressive strength. ASTM C-1328 sets the standard for air content
in plastic stuccos.
Requirement

F. Water Retention:
Stucco is affected by water retention in three ways:
a. The greater the water retention, the longer the stucco remains workable. With a longer working time, the plasterer does
not have to stop to retemper the stucco. This, in turn, increases efficiency and lowers labor cost. BEST One-Coat Stucco
is formulated to remain workable.
b. Compressive strength and bond strength are reduced with each retempering. BEST One-Coat Stucco does not need
retempering as often as stuccos made from masonry cements; therefore, it retains its strength better.
c. When plastering over block or brick with a high initial rate of absorption, the block or brick can dehydrate the stucco before
it sets chemically. This is especially true if the stucco has low water retention. This can cause the stucco to powder and fail
to develop strength. BEST One-Coat Stucco is formulated for high water retention, so it can be used over highly absorbent
surfaces.
ASTM C-1328 Minimum 70%
BEST One-Coat Stucco 82%
G. Water Resistance:
BEST One-Coat Stucco is formulated to resist water penetration in its finished state. No stucco is waterproof.
PRODUCT USAGE
A. Suggested Mixing Instructions:
a. BEST One-Coat Stucco has been formulated to require only 4 to 6 gallons of water, depending on the amount of sand used
and the moisture content of the sand.
b. Use 2.5 to 3.0 cubic feet of loose damp sand per bag of BEST One-Coat Stucco. This is
19 to 22.5 gallons,
3.5 to 4.0 5-gallon buckets, * or
15 to 18 No. 2 shovelsful. **
* Loose fill and screed off. Most 5-gallon plastic buckets level full hold 5.5 gallons
** Shovel capacity varies with moisture of sand and the operator.
B. BEST One-Coat Stucco is designed to be gun applied, or to be applied by hand.
C. For consistent results, use a mechanical mixer and measure the sand and the water. Mixing 4 minutes will improve the work-
ability and water retention for hand application. Over mixing will entrain excess air, which will lower the compressive strength.

Composition and Materials:
A blend of portland cement, hydrated lime, high performance pozzolan, and additives.
Bag Weight:
80 pound bags (36.36kg)
TECHNICAL DATA:
Applicable Standards:
ASTM C-1328 for Type S
UBC 25-1
A. Fineness:
This is determined by screening the unmixed cement through a No. 325 mesh sieve.
ASTM C-1328 24% Maximum
UBC 25-1 24% Maximum
BEST S & B 14.7%
B. Autoclave Expansion:
This test is used to predict the long-term durability of the product.
ASTM C-1328 1% Maximum
UBC 25-1 1% Maximum
BEST S & B 0.04%
C. Time of Setting:
Initial time of set must be long enough to allow adequate time to apply and trowel the product. The final set time must be
rapid enough not to interfere with production.
Initial Set, Minimum Final Set, Maximum
ASTM C-1328 Not Less Than 90 Minutes (1.5 Hours) Not More Than 24 Hours
UBC 25-1 Not Less Than 90 Minutes (1.5 Hours) Not More Than 24 Hours
BEST S & B 105 Minutes (1.75 Hours) 230 Minutes (3.8 Hours)
D. Compressive Strength:

7-day 28-day 90-day 365-day
ASTM C-1328 Minimum 1300 psi 2100 psi N/A N/A
BEST S & B 1700 psi 2400 psi 2900 psi 4000 psi
BEST Scratch & Brown (S&B) Stucco Type S
E. Air Content:
Air content affects workability, yield and strength. Plasterers want a high air content to increase workability and yield. However,
the higher the air content, the lower the compressive strength. ASTM C-1328 sets the standard for air content in stuccos.
Requirement
ASTM C-1328 Minimum/Maximum 8/20%
BEST S & B 12/16%
F. Water Retention:
Stucco is affected by water retention in three ways:
a. The greater the water retention, the longer the stucco remains workable. With a longer working time, the plasterer
does not have to stop to retemper the stucco. This, in turn, increases efficiency and lowers cost. BEST S & B Stucco
is formulated to remain workable.
b. Compressive strength and bond strength are reduced with each retempering. BEST S & B Stucco does not need
retempering as often as stuccos made from masonry cements; therefore, it retains its strength better.
c. When plastering over block or brick with a high initial rate of absorption, the block or brick can dehydrate the
stucco before it sets chemically. This is especially true if the stucco has low water retention. This can cause the
stucco to powder and fail to develop strength. BEST S&B Stucco is formulated for high water retention, so it can be
used over highly absorbent surfaces.
ASTM C-1328 Minimum 70%
BEST S & B 82%
G. Water Resistance:
BEST S & B Stucco is formulated to resist water penetration in its finished state. No stucco is waterproof.
PRODUCT USAGE:
A. Suggested Mixing Proportions:
鈥? 1 bag BEST Scratch & Brown Stucco.
鈥? 3 cubic feet of ASTM C-897 sand (Stucco Sand)
鈥? 3 to 4 gallons of water depending on the moisture content of the sand.
B. Suggested Mixing Sequence:
a. Add three-fourths of the required water to mixer. Start off with 2.5 gallons per bag of stucco. Adjust based on
experience and required workability.
b. Add half of the required sand.
c. Add pigments if used. To obtain maximum benefit of pigments, mix for 2 to 3 minutes before adding stucco.
If pigments are used, always add weighed quantities of pigment.
d. Add BEST Scratch & Brown Stucco.
e. Add remaining sand.
f. Mix until a uniform color and texture is observed.
g. Add additional water to achieve desired workability.
h. Machine mixing for 4 to 5 minutes is recommended to obtain the maximum workability. Mixing over 5 minutes is
not recommended.
STORAGE, APPLICATION, AND CURING:
Shelf life is about 6 months. Store in a dry area off the ground.
Do not add air-entraining agents, mortar fat, antifreeze, accelerators, or waterproofing agents, as they may interfere with the
chemical integrity of this product. Do not apply at temperatures below 40掳F, or when freezing temperatures are
anticipated within 24 hours. Apply the scratch coat a minimum of 3/8-inch thick. After it has cured sufficiently, apply the brown
coat a minimum of 3/8-inch thick. Delaying application of the brown coat for 48 hours will reduce the number of hairline cracks
in the stucco.
All cementitious stuccos require moisture to cure. Moist cure for 48 hours with regular fogging spray after stucco has taken its
initial set (2 to 4 hours).

Another Performance ISG Resources Building Product
BEST Mason鈥檚 Portland Cement
PRODUCT DESCRIPTION
BEST Mason鈥檚 Portland is the 鈥済reen鈥? equivalent to ASTM C-150 Type I Cement.
Basic Use:
BEST Mason鈥檚 Portland is an ASTM C-595 Type IP cement (Type I cement with pozzolan addition) and also can be classified
as an ASTM C-1157 Type GU cement (General Use). It can be used wherever Type IP cements or GU cements are specified
or authorized. It is an excellent choice for making cement/lime mortars and stuccos on the job-site. Each year, more stan-
dards requiring ASTM C-150 Type I portland cement recognize Type IP cements as an acceptable alternative.
Composition and Materials:
A blend of portland cement and high performance pozzolan.
Bag Weight:
94 pound bags (42.7kg)
TECHNICAL DATA
Applicable Standards:

PRODUCT USAGE
A. General:
BEST Mason鈥檚 Portland is designed to be used wherever portland cement Type I is utilized. BEST Mason鈥檚 Portland is
available only in bags, thus it is not practical to use in ready-mix applications.
B. As a Mortar or Stucco:
BEST Mason鈥檚 Portland is especially useful for job-site mixing of mortars and stuccos because the spherical shape of the
pozzolan particles leads to increased workability. The major differences that tradesmen will notice will be the increased
workability with less mixing water. Following are suggested starting formulas:
Type N Mortar Scratch Coat Stucco Texture Coat Stucco
1 bag BEST Mason鈥檚 Portland 1 bag BEST Mason鈥檚 Portland 1 bag of BEST Mason鈥檚 Portland
0.5 bag of hydrated lime 0.5 bag of hydrated lime 0.5 bag of hydrated lime

1 bag BEST Mason鈥檚 Portland 1 bag BEST Mason鈥檚 Portland
0.25 bag of hydrated lime 0.5 bag of hydrated lime
3.75 cubic feet of masonry sand 4.5 to 7.5 cubic feet of plaster sand
C. For Concrete Work:
BEST Mason鈥檚 Portland gives the advantages of pozzolan incorporation to small concrete pours. These advantages include
reduced bleeding and segregation, more impervious concrete, reduced expansion resulting from alkali aggregate reaction,
and continued strength gain over time.
STORAGE, APPLICATION, AND CURING:
Shelf life is about 6 months. Store in a dry area off the ground.
Do not add air-entraining agents, mortar fat, antifreeze, accelerators, or waterproofing agents, as they may interfere with the
chemical integrity of this product. Do not use as mortar, stucco or concrete at temperatures below 35掳F, or when freezing
temperatures are anticipated within 24 hours.
Follow traditional guidelines for curing.
GENERAL GUIDANCE:
Work cleanly and neatly. Fewer problems are observed on a clean work site. Let鈥檚 give our customers the very BEST.

Ingestion: Rinse mouth out with water. Give water or milk if person is conscious. Do not give anything to convulsing or
unconscious person. Seek medical attention.
SECTION 6 鈥? CONTROL AND PROTECTIVE MEASURES
Respiratory Protection: Minimize dust. If airborne dust exposure approaches the TLV or PEL (Section 1), use half-mask or
full-face air purifying respirator equipped with NIOSH or MSHA-approved high efficiency filters for protection against
pneumoconiosis-producing dust. An airline respirator may be required where dust levels are extremely high.
Protective Gloves: Limit contact with skin. Use impervious abrasion- and alkali-resistant gloves, boots, long-sleeved shirt,
long pants, or other suitable skin coverings. Promptly remove any dusty clothing or clothing with wet/dampened product,
and launder before reuse.
Eye Protection: Wear safety glasses with eye shields, or goggles or face shield as appropriate to avoid contact with eyes.
Wear tight-fitting un-vented or indirectly vented goggles to avoid injury in high dust environments. Do not wear contact
lenses when handling cement-containing products.
Ventilation To Be Used: Keep dust levels below PEL. Use general and local exhaust ventilation and dust collection systems
to keep dust levels within acceptable limits.
Other Protective Clothing and Equipment: None normally required. Wear long sleeves and long pants to reduce skin
contact. Use work gloves, goggles and face shield as necessary. In dusty conditions, coveralls may be required. Alkali
burns may result from skin contact.
Hygienic Work Practices: Do not allow dust to get into eyes, to be inhaled, to be swallowed, or to remain on skin if irritation
occurs. Practice good personal hygiene. Wash or shower after use. Launder clothes as normal.
SECTION 7 鈥? PRECAUTIONS FOR SAFE HANDLING / LEAK PROCEDURES
Steps To Be Taken If Material is Spilled or Released: Avoid creating airborne dust. Pick up with shovel, mechanical
equipment, or other dry method. Wet methods may be used on spills. Chemical neutralization usually is not required.
Waste Disposal Methods: Handle as inert bulk material. Material may be disposed of as a non-hazardous solid waste
consistent with state, federal, and local disposal regulations. Disposal in a sanitary landfill is usually adequate.
Precautions To Be Taken in Handling and Storage: Keep material dry in storage. No special handling required. Avoid
creating airborne dust.

Hill Country Mortar Cement Type N
PRODUCT DESCRIPTION:
Basic Use:
Hill Country Mortar Cement Type N is intended for use in general brick, block, and stone masonry construction up to four
floors in height where bond strength, extent of bond, or water resistance is important.
Composition and Materials:
A blend of portland cement, hydrated lime, high performance pozzolan, and additives. Hill Country Mortar Cement Type N
has been formulated to comply with ASTM C-1329 Type N and, when mixed with an appropriate amount of sand, ASTM
C-270 Type N standard for cement-lime mortar.
Bag Weight:
70 pound bags (31.8kg)
TECHNICAL DATA:
Applicable Standards:
ASTM C-1329 for Type N
UBC 21-14
A. Fineness:
This is determined by wet sieving the mortar cement through a No. 325 mesh sieve.
ASTM C-1329 24% Maximum
UBC 21-14 24% Maximum
Hill Country Mortar Cement Type N 20.5 %
B. Autoclave Expansion:
This test is used to predict the long-term durability of the product.
ASTM C-1329 1% Maximum
UBC 21-14 1% Maximum
Hill Country Mortar Cement Type N -0.0190%
C. Time of Setting:
Mortar must remain workable to give masons time to use it and tool joints. But if it fails to firm set within 24 hours,
the number of courses of brick laid per day may be reduced.
Initial Set, Minimum Final Set, Maximum
ASTM C-1329 Not Less Than 120 Minutes (2 Hours) Not More Than 1440 Minutes (24 Hours)
UBC 21-14 Not Less Than 120 Minutes (2 Hours) Not More Than 1440 Minutes (24 Hours)
Hill Country Mortar Cement Type N 123 Minutes (2.05 Hours) 250 Minutes (4.1 Hours)
D. Compressive Strength:
Compressive strength is the main criterion for selecting a mortar if brick spacing is the primary concern. Hill Country
Mortar Cement Type N exceeds ASTM standards and continues to gain strength over time.
7-day 28-day
ASTM C-1329 Minimum 500 psi 900 psi
UBS 21-14 Minimum 500 psi 900 psi
Hill Country Mortar Cement Type N 1100 psi 1900 psi
Hill Country Mortar Cement Type N
E. Flexural Bond Strength:
Bond strength and extent of bond are the main criteria for selecting a mortar if the ability to bind bricks together is the
primary concern. While extent of bond as a parameter cannot be incorporated into a mortar, workability can be
incorporated. With good workability, a skilled mason can lay brick with full head and bed joints and have a very high extent
of bond. Hill Country designs cements to impart impressive bond strength and to be sufficiently workable to allow a high
extent of bond. A positive byproduct of high bond strength and high extent of bond is water resistance, since most leakage
through a brick wall is at the interface between the brick and the mortar or in areas where the mortar was inadvertently
omitted.
ASTM C-1329 Minimum 70 psi
UBC 21-14 Minimum 71 psi
Hill Country Mortar Cement Type N 78 psi
F. Air Content:
Air content affects workability, yield and strength. Masons want a high air content to increase workability and yield. However,
the higher the air content, the lower the compressive strength and bond strength.
ASTM C-1329 Minimum/Maximum 8/16%
UBC 21-14 Minimum/Maximum 8/16%
Masonry Cement 16-21%
Hill Country Mortar Cement Type N 11.4%
G. Water Retention:
Mortar is affected by water retention in three ways:
a. The greater the water retention, the longer the mortar remains workable. With a longer working time, the mason
does not have to stop to retemper the mortar. This, in turn, increases efficiency and lowers cost. Hill Country Mortar
Cement Type N is formulated to remain workable.
b. Ultimate compressive strength and bond strength are reduced with each retempering. Hill Country Mortar Cement
Type N does not need retempering as often as conventional mortars; therefore it retains its ultimate strength better.
c. When using brick with a high initial rate of absorption, the brick can dehydrate the mortar before it sets chemically.
This reduces the bond strength and the compressive strength when using a low water retentive mortar. Hill Country
Mortar Cement Type N has high water retention, and thus does not dehydrate before chemical hydration occurs.
ASTM C-1329 Minimum 70%
UBC 21-14 Minimum 70%
Hill Country Mortar Cement Type N 85% average
H. Water Resistance:
Hill Country Mortar Cement Type N is formulated to resist water penetration in its finished state. No mortar is waterproof.
PRODUCT USAGE:
A. Suggested Mixing Proportions:
鈥? 1 bag Hill Country Mortar Cement.
鈥? 3 cubic feet of ASTM C-144 sand (Masonry Sand) 鈥? (18 No. 2 shovelfuls or 4 5-gallon buckets).
鈥? 3 to 4 gallons of water depending on the moisture content of the sand.
B. Suggested Mixing Sequence:
a. Add three-fourths of the required water to mixer. Start off with 2.5 gallons per bag of Mortar Cement. Adjust based on
experience and required workability.
b. Add half of the required sand.
c. Add pigments if used. To obtain maximum benefit of pigments, mix for 2 to 3 minutes before adding Mortar
Cement. If pigments are used, always add weighed quantities of pigment.
d. Add Hill Country Mortar Cement.
e. Add remaining sand.
f. Mix until a uniform color and texture is observed.
g. Add additional water to achieve desired workability.
h. Machine mixing for 4 to 5 minutes is recommended to obtain the maximum workability. Mixing over 5 minutes is
not recommended.

Cement Type S has high water retention, and thus does not dehydrate before chemical hydration occurs.
ASTM C-1329 Minimum 70%
UBC 21-14 Minimum 70%
Hill Country Mortar Cement Type S 80% average
H. Water Resistance:
Hill Country Mortar Cement Type S is formulated to resist water penetration in its finished state. No mortar is waterproof.
