Thick Concrete Repair Mortar
Fiber Reinforced Heavy Duty Concrete Repair Mix

Durával TRO – Don’t Just Repair It… Durável It!
Pea gravel can be added for repairs up to four inches deep. Duravel TRM is formulated specifically as a repair mortar that will gain strength quickly without shrink cracking. The just-add-water mortar system is installed with conventional concrete tools. Superior bond strength is achieved by using in conjunction with Durável LBA bonding agent.
MIXING INSTRUCTIONS
Mix single bags in clean 5-gallon pails with a helical mixing blade or use mortar mixer for multiple bags. Water demand varies with environmental conditions and application, between 3 and 4 quarts per bag (2.8 to 3.8 liters). For best results and longest pot life use clean, cold water – run hot water out of hoses prior to using for mixing – and keep bags cool by not storing in direct sun. Measure mix water into mixing vessel. While mixing slowly add the bag contents then mix to a lump-free consistency, being sure to scrape any unmixed product from the sides and bottom of the mixing vessel. Product must be thoroughly wetted prior to adding pea gravel (if applicable). Mixed product should be applied promptly. If the product stiffens in the bucket dispose of the mix, do not add more water.
APPLICATION INSTRUCTIONS
