KOLD-FLO® Crack Filler Easy Application Instructions

KOLD-FLO® Crack Filler Easy Application Instructions


1. Using a broom or leaf blower, blow or sweep out debris from cracks. Cracks must be free of debris prior to application.

    2. Pour KOLO-FLO® crack filler into three quarters of the length of the crack. Product can be applied directly from the bottle, using a pour pot or UNIQUE’s CRACK-N-TACK® portable pump.

    3. Squeegee KOLD-FLO® crack filler into the crack using a “U” or “V” shaped squeegee. Proper squeegeeing will decrease surface cure time and avoid tracking of KOLD-FLO crack filler. A second application may be necessary for cracks deeper than two inches.
