Description

QM-1s Restore is a single component,high strength, fiber reinforced, shrinkage compensated cement mortar enhanced with a monocrystalline quartz aggregate. QM-1s was designed to structurally repair deteriorated metal, concrete and masonry structures. QM-1s delivers a monolithic one-pass vertical surface application up to three inches in thickness by low pressure spraying or centrifugally casting.

Recommended For

Vertical and overhead repairs to concrete or masonry sewer manholes, wetwells, metal pipes, water treatment facilities, tunnels, navigation locks, and dams.

Features & Benefits

  • Quality controlled one-component blend for uniform results
  • High early and ultimate compressive, flexural and bond strengths
  • Resistant to sulfate attack
  • Extremely low permeability

Packaging

Quadex QM-1s Restore is supplied in 60 lb. (27 kg) polyethylene lined bags.

Yield

One 60 lb. (27 kg) bag of Quadex QM-1s Restore yields approximately .54 cu. ft. and will cover 12.5 sq. ft. at a 1/2 in. thickness.

Procedure

Prepare the surface to be restored by removing unsound concrete, dirt, dust, oil, and other debris using high pressure (3500 psi) water blasting. Air blast excess water with an oil free air compressor. This will provide a clean, damp surface to allow for a good bond.

Use approximately 0.7 to 0.9 gallons of water per 60 lb. bag of Quadex QM-1s Restore. First add water to mixer. Start mixer motor and add Quadex QM-1s Restore until mortar is completely mixed.

Apply Quadex QM-1s Restore by low-pressure spraying on vertical or overhead surfaces to a monolithic thickness of 1/2 to 3 inches in one pass. Trowel to a smooth surface.

Curing

Cure in accordance with current ACI recommendations. Use a two coat application of a manufacturer approved water based curing compound.

Quadex warrants its products to be free of defects in material and workmanship. Quadex will replace any product proved to be defective when applied in accordance with manufacturer’s instructions. Quadex obligation shall be limited solely to such replacement. There are no other warranties by Quadex expressed or implied.
