DESCRIPTION
BOND-IT is a masonry bonding-adhesive that will permanently
bond new concrete, stucco and plaster to concrete or cinder
blocks, brick, concrete slabs, old concrete and many other
bases. It is also a fortifying admixture for concrete
and plaster. Since introduction in the market it has
been used with success to overcome two major problems associated
with the use of concrete and plaster in the construction industry.
(l) It eliminates the difficulty of bonding
these materials to themselves or to other substrates when
used as a coating between them.
(2) It reduces the brittleness and lack of
impact strength inherent in cementitious materials, when used
as an admixture.
RECOMMENDED USES
Plaster Adhesive – Bond-It will permanently
bond stucco and plasters to concrete or cinder blocks, stone,
brick, concrete slabs, tile, plywood, sheet rock, rock lath,
hardboard and other similar bases.
Concrete Adhesive – Bond-It will bond new concrete
to old without the usually necessary laborious scarification
process. Its bond strengths used with proprietary floor
toppings have been tested by ASTM procedure C-190-49 for the
determination of tensile strength in concrete, with the following
value as typical results:
BOND-IT as an adhesive only
435 psi
BOND-IT as an adhesive and admix
525 psi
CONCRETE ADMIXTURE –
When Bond-It is substituted for a portion of the liquid contact
of a mortar; the resulting concrete has a high degree of resiliency,
and will cure to a high tensile strength, even under adverse
conditions. The resiliency BOND-IT imparts to concrete is
completely absent in concrete not containing it, and the importance
of this resiliency becomes evident in patching a concrete
floor. Concrete floor patches can be feather edged when
BOND-IT is used as bonding agent and as an admixture.
(This eliminates the deep cutting normally required to obtain
a satisfactory patch). Such patches
can take foot traffic, usually with 24 hours, and heavy traffic
after seven days . . . unless high early strength cements
are used.
USES NOT RECOMMENDED
Do not use BOND-IT in areas continually exposed to water,
such as swimming pools. It many be used with excellent
results where only intermittent water exposure is encountered.
SURFACE PREPARATION AND APPLICATION
General – Any surface to which BOND-IT is to be applied
must be structurally sound, free of oil, grease, mildew, efflorescence,
scale, dust, rust, and other foreign matter. Cracks
should be cleaned out. Gloss surfaces should be sanded
to remove gloss. Best results are obtained if porous surfaces
are damp, or moist, but without puddles. Temperature
should be 45-f or higher-never lower, BOND-IT is colored with
a blue fugitive dye to show area coated. Brush, roller
or spray may apply it. Clean tools with water immediately
after using.
SPREAD RATE – One gallon of BOND-IT
will usually cover 250-300 sq. ft. Plaster Adhesive Bond-It
may be applied over damp walls, and if the substrate is a
very porous, cementations surface, it should be purposely
dampened before application.
IMPORTANT – for maximum bond strength,
apply the plaster coating to the BOND-IT coated surface while
it is still tacky. This is usually 20 minutes to 1 hour
after application. Bond strength will deteriorate if
the film of BOND-IT has been allowed to age excessively before
applying plaster. Frequently a dried film can be retackified
by wetting it with water, unless it has cured. Curing
takes place rapidly in dry, hot, windy areas, and no amount
of wetting will retackify a cured film. If the film
does cure, a fresh coat of BOND-IT must be applied before
applying plaster.
CONCRETE ADHESIVE – Be sure concrete
substrate is thoroughly cleaned. Surface should be moist,
without puddles, when BOND-IT is applied. Apply new
mortar before BOND-IT has dried, and while still tacky-usually
20-minutes to 1 hour after application. The strongest
bonds are obtained by adding small amounts of BOND-IT to the
fresh mortar.
CONCRETE ADMIXTURE – Adding BOND-IT
to mortar as a substitute for part of its liquid content results
in a high degree of resiliency, and high tensile strength.
Assuming that a mortar contains a full 94-lb. bag of Portland
cement, the quantity of BOND-IT to be used would be:
1. Maximum allowable concentration 2 gallons BOND-IT , 18.4
lbs.
(10%) based on 94-lbs. of cement.
wet – 10 lbs. dry
2. Minimum allowable concentration 1 gal. BOND-IT 9.2. lbs.
(5%) based on 94-lbs of cement
wet – 5 lbs. dry
It is good practice to dilute BOND-IT with an equal amount
of batch water before blending with the dry cement mix.
HANDLING
BOND-IT is freeze-thaw stable, and has been found to have
undamaged bonding characteristics even after subjection of
five freeze-thaw cycles. However, care must be taken
to prevent freezing of this product and the manufacturer cannot
assume responsibility for material which has been subjected
to freezing conditions of varying severity.
