An exceptional plasticizer for
all your
Eze-Trowel™ is a high performance stucco and mortar plasticizer. It can be used as an admixture in all stucco and mortar mixes. Eze-Trowel™ replaces lime, soaps, air entraining agents and other plasticizing materials. The ingredients in Eze-Trowel™ are designed to function with the common ingredients of stucco and mortar mixes to retain water and produce an easy working mix that requires less tempering. When using Eze-Trowel™
in the mix, your stucco or mortar mixes:
Eze-Trowel™ cannot be used in conjunction with any other plasticizer or air entraining agent. Why
is it better than lime and other plasticizing materials? What

Mix
It Fast and Easy! Follow these directions to get maximum workability: Step 1: Start Mixer Add Eze-Trowel™, Portland Cement, ½ of the sand and about ½ of the water. Step 2: Mix for 2-3 minutes. Step 3: With mixer running add remaining sand and water. Step 4: Mix until mortar has desired workability. NOTE: To
develop maximum workability, mix for a total of 6-8 minutes.
Tested by Portland Cement
Association Physical Properties of Eze-Trowel™ (check out Test Results) The material identified as Eze-Trowel™ was received by: CONSTRUCTION TECHNOSLOGY LABORATORIES A Division of The Portland Cement Association 5420 Old Orchard Road Skokie, Illinois 60077 U.S.A. Objective To compare two mortars, Types M and S, as prepared with conventional Portland cement, lime and sand, and as prepared with Portland cement, Eze-Trowel™ and sand. Test Procedures The mortars
prepared with Eze-Trowel™ were tested according to CSA A179M
"Mortar for Unit Masonry" for water retention, cube
compressive strength, time of set, air content and autoclave expansion. A tensile bond
strength test as developed for the Portland Cement Association by W.H.
Kuenning was used to compare the bonding characteristics of these
mortars. In this test method a couplet made of two half-bricks is
subject to direct tension. Four wallettes were
constructed to evaluate the effectiveness of these mortars when
subjected to 50 freeze-thaw cycles. The back, sides and top of the
wallettes were covered with a n impermeable coating of epoxy. The cured
specimen was placed face down, on ¼ inch square rods, in a container of
cold water for a 24-hour period and then stored in air in a freezing
chamber (0° F) for 16 hours. The specimen was then placed face down in
room temperature water for an 8-hour period and returned to the freeze
chamber for 16 hours. This 8-hour thaw in water and 16-hour freeze in
air cycle was repeated for a total of 50 cycles. An evaluation of the brick characteristics was performed according to CAN3-A82.2-78 "Methods of Sampling and Testing Brick." Test Results
Eze-Trowel™ was
used as a replacement for lime but 1/3 of the normal amount was used.
Specimen Fabrication Five couplets and a
wallette for each mortar type and composition were fabricated from the
same batch of mortars by this writer who is an experienced bricklayer.
The couplets were two half bricks and the wallettes were 21/2 brick wide
(21 in.) and three brick high (7.5 in.). Mortar for the
fabrication of these specimens was prepared in a Lancaster mixer. All
materials were mixed for 10 minutes after the last water was introduced
to the mix. Water was gauged by eye by the bricklayer. Mortar
proportions were as follows:
Specimen Storage Couplets and
wallettes were loosely covered with polyethylene film as a protection
from drafts and retained in a storage room with temperature of 75° ± 5°
F for 28 days before testing. Test
Results – Direct Tension
All four wallettes completed 50 cycles of freeze-thaw without any cracking, spalling or chipping of any kind. Both Type M specimens had a hairline step crack that was caused by handling procedures. Test of Clay Brick as Per CAN3-A82.2 – 78 Measurement Length Average - 8.09 Width Average - 3.70 Depth Average - 2.26 Average core diameter 1.3724 inches, 3 cores per brick. Compressive Strength Average
– 15,550 psi. Absorption
Modulus of Rupture Average 2600 psi. Efflorescence
Freeze – Thaw All specimens had identical weights after 50 cycles of freeze-thaw as they did before the test, indicating no change or damage. Discussion The mortar
characteristics as tested per A179M are all satisfactory and compare
well with conventional mortar systems. The water retention of Eze-Trowel™
Type M is marginal but acceptable. The result of
the direct tension test show that both Eze-Trowel™ mortars show
a significantly higher bond strength than their cement and lime
counterparts. Type S with Eze-Trowel™ was 100% higher and Type
M with Super Spread was 43% greater than the cement and lime mortar. The bricks used in this research were of good quality and suffered no damage during the freeze-thaw testing. Conclusion Types M and S
mortars prepared with Eze-Trowel™ exhibited good handling
characteristics, compliance with current standards of evaluation,
superior bond strength and the ability to resist freeze-thaw.
