Flexane® Fast-Cure Rubber Repair Liquid
Over several years of continual traffic, these expansion joints became deteriorated. As a result of failed expansion joints, spider cracking began. The uneven floor surface caused problems such as difficulty moving wheeled equipment, and forklift load shifting.
Loose, deteriorated concrete was mechanically removed. Remaining concrete was roughened to provide a profile. All surface areas were then chemically cleaned using Cleaner Blend 300. FL20 Primer was applied into the expansion joints and cracks and allowed to cure or dry for 15 minutes. A polypropylene backer was stuffed 3/4" into the expansion joints and cracks. The polypropylene backer will prevent deep migration of Fast Cure Liquid, and reduce the volume required. Fast Cure Rubber Repair Liquid was injected into the damaged or repair areas using Devcon's Auto Mix Application System. This product is self- leveling and provided a smooth, flexible, (450% elongation), expansion joint seal. Fast Cure Rubber Repair Liquid also provided a functional cure in only 90 minutes, reducing repair downtime.
