Installation Guide

A polymer modified sand cement repair mortar requiring only the
addition of clean water. For resurfacing, patching and general repairs
to concrete walks, walls, driveways, patios and masonry. Can be used
for applications from 1/2 inch (13 mm) down to a featheredge or as a
brush coat.
SAFETY:
READ and UNDERSTAND the Material Safety Data Sheet (MSDS) before using
this product. WARNING: Wear protective clothing and equipment. See HMIS
block. For emergency information, call CHEMTREC at 800-424-9300 or 703-
527-3887 (outside USA). KEEP OUT OF REACH OF CHILDREN.
PREPARATION:
Use only when the product, air and surface temperature are above 50° F (10°
C) and remain above 50° F (10° C) for a minimum of 24 hours. The substrate
must be sound, clean, hard and free of dust, dirt, grease, oil, paint, sealers,
curing compounds and other materials that will interfere with the bonding of
the new material. Do not mix any materials with this product other than water.
DO NOT USE WITH A BONDING AGENT.
MIXING:
Add water a little at a time until the desired consistency is reached. When
mixing small amounts use approximately 6 parts powder to 1 part water by
volume. (See table below) For improved mixing, use a high torque variable
speed drill and run at low r.p.m. to avoid splattering. After mixing allow mate-
rial to stand for 5 minutes. Material may stiffen during this time. Remix mate-
rial. If too stiff add a small amount of water to achieve desired consistency.
AVOID A SOUPY MIX. Excess water reduces strength, durability, bond and can
cause cracking. In cold weather use warm water to accelerate the set. Use
cold water to slow the set in hot weather. Retempering impairs performance.
Do not mix more than can be used in 30 minutes.
Water amounts are approximate
PLACEMENT AND FINISHING:
Level with a screed and allow the bleed water to evaporate. Use a float to
remove surface imperfections and trowel to a smooth finish. For a rougher
surface, use a broom. Refer to ACI 302. Finishing cementitious materials too
early, or over-working the materials can cause dusting, cracking, scaling and
a weak surface.
BRUSH COAT APPLICATION: Lightly dampen the surface. Mix SAKRETE®
Top’n Bond® Concrete Patcher to a thick paint consistency. Apply with a soft
bristle broom, masonry brush or squeegee. Maximum thickness for brush
coat application is 1/8 inch.
CURING:
Curing means maintaining proper moisture and temperature. Account for
local environmental conditions when selecting the curing method. High heat,
low humidity or wind will increase the evaporation of water. Keep the surface
damp, using a sprinkler, wet burlap, Sakrete Cure ‘N Seal or cover with plastic
for several days as needed. In cold weather adequately cover and keep from
freezing for a minimum of 24 hours. Refer to ACI 308. Patched area may be
open to foot traffic after 1 day and vehicular traffic after 3 days.
STORAGE:
STORAGE: Store in a tightly closed container off the floor in a dry place.

COVERAGE:
For general repairs
One 40 lb. bag (18.1 kg) will cover approximately 18 sq. feet (1.6 sq. m) at
1/4 inch (6.3 mm) thick.
For brush coat application
One 40 lb. bag (18.1 kg) will cover up to 80 sq. feet but varies with
roughness of surface.
To determine the number of bags needed: Multiply (length x width x depth),
divided by yield from chart above.
