between 60 and 90°F. Low temperatures or temperature fluctuations may cause
All dirt, foreign contaminants, oil and
laitance must be removed to assure a trouble free bond to the substrate. A test
should be made to determine that the concrete is dry; this can be done by
placing a 4’ x 4’ plastic sheet on the substrate and taping down the edges. If
after 24 hours, the substrate is still dry below the plastic sheet, then the
substrate is dry enough to start repair work. This product is intended for
hairline cracks and other fractures up to an 1/8 inch in width. Remove all
unsound concrete from within the crack to be repaired and thoroughly vacuum all
debris and dust from within the crack opening.
has a mix ratio of 2 part A to 1 part B by volume. To mix, simply measure out
two parts by volume for part A with one part by volume for part B. Mix the two
components together thoroughly with slow speed mixing equipment such as a jiffy
mixer, putty knife or spatula until the material is thoroughly mixed and uniform
in color. Mix only an amount of material that can be used in the allotted pot
life period. Insufficient mixing or improper mixing may result in product
No priming is necessary.
The mixed material can be applied by marginal trowel, putty knife or any
other suitable equipment. Make sure that all unsound concrete is removed
prior to repairing the area.
RECOAT OR TOPCOATING
Allow the Epoxy Novolac Chemical Resistant Crack Filler Product #655 to cure (tack free) prior
to coating over the applied material. If excessive amounts are spread well
beyond the crack repair or in areas where surface repairs have been implemented,
it is best to check the cured areas for any possible amine blush (a whitish,
greasy film or deglossing) prior to coating over this material. If a blush is
present, it can be removed by any standard type detergent cleaner prior to
topcoating or recoating. Many epoxy coatings and urethanes are compatible for
use over this product as well as multiple coats of this product.
Caution! Some cleaners may affect the color of the
fast set gel installed. Test each cleaner in a small area, utilizing your
cleaning technique. If no ill effects are noted, you can continue to clean with
the product and process tested.
Restrict the use of the area to
light traffic and non-harsh chemicals until the coating is fully cured (see
technical data under full cure). It is best to let the floor remain dry for the
full cure cycle.
