Product Description
SealBoss ® 6500 HM QuickFix is a technologically advanced, two component, 7:1 ratio, 100% solids, flexible polyurea elastomer product with a retarded pot life.
SealBoss ® 6500 HM 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 free time is 5 to over 15 minutes depending on temperature. This permits to reopen the jobsite to vehicle and foot traffic just one hour after the application. Exposure to sunlight (UV) may cause discoloration, however the physical properties are essentially unaffected. Ask your SealBoss technician for details. The product is for professional use.
Installation Guidelines
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 parts at 7:1 ratio by volume of Component “A” and Component “B” preferably by mixing the B side into the A side container. Mix only the quantity that can be used within the pot life of the product. The material can be mixed with sand or quartz sand and other approved fillers in a ratio of up to 30%. Use of filled product will prolong the reaction time. Do not add solvents or thinners. 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.
