Durável TRO – Don’t Just Repair It… Durável It!

You can add pea gravel for repairs up to four inches deep. Duravel TRM is a repair mortar formulated specifically to gain strength quickly without shrink cracking. You install the just-add-water mortar system with conventional concrete tools. Using Durável LBA bonding agent in conjunction achieves superior bond strength.


Mix single bags in clean 5-gallon pails with a helical mixing blade, or use a 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).

Use clean, cold water to get the best results and make the mixture last longer. Before mixing, run hot water out of the hoses. Also, keep the bags cool by not storing them in direct sunlight.

Measure the mixed water into the mixing vessel. Add the bag contents slowly while mixing. Make sure there are no lumps, and scrape any unmixed product from the sides and bottom of the mixing vessel.

Thoroughly wet the product before adding pea gravel (if applicable). Apply mixed product promptly. If the product stiffens in the bucket, dispose of the mix; do not add more water.


Use Durável LBA liquid bonding agent to prime the surface before applying Durável TRM repair mortar. Apply repair while the bonding agent is still tacky.

Pour out mixed product onto the primed repair area, then spread it with trowels and/or squeegees. You can apply Durável TRM neat at a thickness of up to 2″.

Use the product in lifts for thicker repairs. You can apply Durável TRM at 2″ and 6″ thicknesses when blending it with washed pea gravel. Do not apply Durável TRM in locations that are permanently submerged.


Use neat to Fill spalls and damaged areas in thicknesses up to 2″ per lift, To repair depths greater than 2″, add 20% washed pea gravel to the mix (10 pounds of gravel per 50-pound mix).

.43 cu ft per bag.

COVERAGE ½” Thickness = 11 ft² (1 m² @ 13 mm)

1” Thickness = 5.5 ft² (.5 m² @ 25.4 mm)

2” Thickness w/ pea gravel = 3.3 ft² (.31 m² @ 50.8 mm)

3” Thickness w/ pea Gravel = 2.2 ft² (.2 m² @ 76.2 mm)

4” Thickness w/ pea Gravel = 1.7 ft² (.15 m² @ 101.6mm)
