SealBoss ® 6500 QuickFix is a high quality joint and crack filler for concrete substrates in applications that are time critical. It works well in adverse temperature conditions as the material cures in ambient temperatures from -28°C (‑20°F) to 54°C (130°F). The Tack Fee within 5 to 15 Minutes depending on temperature. This permits to reopen the jobsite to traffic just one hour after application in most conditions.
Clean the area of debris and contaminants, such as oils, loose materials, dirt, rubber etc., to allow for good adhesion of the product. Expose clean rough concrete for best results. If using a saw to cut concrete and clean the crack, remove all the dust from the cut out area. Make sure the area is dry. All equipment, pumps and hoses must be dry. Avoid moisture contact with the mixture.
For bulk mixing, pre‑mix each component thoroughly. Proportion equal parts by volume of Component “A” and Component “B” through appropriate metered mixing equipment. Mix only the quantity that can be used within 2 minutes and do not allow mixed material to reside in static mixing head or mixer for more than 1 minute or nozzle blockage may result.
Do not add solvents. They will prevent proper cure. Not for sealing cracks and joints under hydrostatic pressure or with extreme movement. Material is a vapor barrier after cure. Minimum age of concrete must be 21‑28 days, depending on curing and drying conditions prior to applications. Exposure to sunlight (UV) may cause discoloration, however the physical properties are essentially unaffected. Product may exhibit bubbling and/or compromised adhesion in excessive concrete or ambient moisture levels. Ask your SealBoss ® technician for details. The product is for professional use.
