Epoxy Novolac Chemical Resistant Crack Filler Product #655 is a two component 100% solids Epoxy Novolac crack filler (gel) designed for shallow repairs on either vertical or horizontal surfaces. Because Epoxy Novolac Chemical Resistant Crack Filler Product #655 is a 100% solids formulation, it can be applied thicker on horizontal surfaces when required.
Epoxy Novolac Chemical Resistant Crack Filler Product #655 is recommended for repairing cracks and defects in concrete or masonry where a high chemical exposure is possible.
None necessary
Optional. This product can be over-coated with many suitable epoxy and urethane products.
Store Epoxy Novolac Chemical Resistant Crack Filler Product #655 at normal room temperature before using. Continuous storage should be between 60 and 90°F. Low temperatures or temperature fluctuations may cause crystallization.
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.
This product has a mix ratio of 4 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 failure.
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.
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.
Use Xylene.
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.
