        MIXING AND 
        APPLICATION INSTRUCTIONS  
    
	
        Epoxy Novolac Chemical Resistant Crack Filler Product #655
	
        PRODUCT STORAGE
	
        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.  
     
	
        SURFACE PREPARATION
	
        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.  
     
	
        PRODUCT MIXING 
    
	
		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.  
     
	
        PRIMING
	
        No priming is necessary. 
	
        PRODUCT APPLICATION
	
        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.  
     
	
        CLEANUP 
    
	
		Use Xylene. 
	
        FLOOR CLEANING
	
        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.  
     
	
        RESTRICTIONS 
    
	
		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.
