Technical Specifications

Application (cont.)
Bonding Dry-Stack Segmental Retaining and Masonry
Walls,
Footings, or Foundations:
 Sound structures require a strong, level foundation, an
aligned footing makes block stacking and troweling much
easier. Footings must be built below the frost line and should
be a minimum of twice the thickness of the blocks used.
Consult your local building codes for information about
footings and slab construction in your area.
Dry-stacking Masonry Units:
 Lay the first course of masonry units in a full bed of Surface
Bonding Cement CR. Make sure this course is straight and
level.
 Dry-stack masonry units in a staggered or running bond
pattern for strength in accordance with ASTM C946. As you
place masonry units in position, slide it against the masonry
units below to smooth out any roughness.
 Surface Bonding Cement CR can be used between masonry
units to maintain a level and properly aligned wall. The better
you are in maintaining a level and aligned wall, the stronger
and more attractive your finished wall will be.
 Dry-stack the rest of the wall before applying the Surface
Bonding Cement CR to both sides of the wall. Apply product
with a trowel in upward strokes, maintaining a uniform
thickness of at least ⅛ in. (3 mm). Follow American Concrete
Institute (ACI) and National Concrete Masonry Association
(NCMA) standards for grout, reinforcing, anchorage, and
control joints. Do not over-trowel.

Curing
Protect from excessive drying due to temperatures, air
movement, and direct sunlight. Like other cement based
materials, Surface Bonding Cement CR gets most of its strength
within 24 hours after application. It is imperative to keep the
new surface area damp for at least 2 days. Wetting the walls
once or twice daily with fogging or a fine mist will ensure
proper curing for strength. Hot, windy or dry conditions may
require more frequent wetting. Wet curing may be minimized
when using Concrete Bonding Additive.
Cleaning
Use clean potable water to clean all tools immediately after use.
Dried material must be mechanically removed. Use a waste
water hardener (e.g. Conglez™ or similar product) for
cementitious waste disposal.
Limitations
 When applying over previously coated and non-porous
surfaces or for difficult restoration and moisture resistance,
use a 50/50 diluted solution of clean water with ProSpec
®
Mighty Bond as the mixing liquid.
 When additional layers are needed to build-up product, apply
second coat after initial set of first coat, while product is still
partially damp and plastic (approximately 2-4 hours).
 Mix only the amount that can be placed in 25-35 minutes.
 Do not over water, retemper, or add additional additives.
Coverage

(3.2 mm) thickness.
