Mortartec Silicate DS

Product Description

Epoxytec Mortartec Silicate DS is an industrial-grade repair mortar designed for dry shotcrete only applications to repair deteriorated concrete, where an early cure, high density overlay is required. The material is a blend of Portland cement, graded silica sand, fibers and silica fume- incorporating corrosion and rust inhibitors.. The mortar is spray applied, typically from ½” to 4” in depth (overhead and vertically) with incredible adhesion. Uses include repairing concrete walls, ceilings, brick, etc. Mortartec Silicate DS provides an extremely dense matrix and will accept coatings at earlier ages than typical Portland cement repair products.

Typical Uses

Typical Uses – Any concrete and masonry surfaces where rehabilitation of an existing structure requires enhancement of the structural integrity using “dry shot” high build overlaying methods. Uses include repairing concrete walls, ceilings, lining brick or concrete infrastructure, etc. Mortartec Silicate DS provides an extremely dense matrix and will accept coatings at earlier ages than typical Portland cement repair products.

  • Industrial infrastructure repair, restoring and overlay rebuilding
  • Wastewater treatment plants
  • Water treatment facilities
Surface Prep

Remove all loose concrete, brick or mortar from affected area by mechanical means. Surfaces shall be free of paints, oils, dirt, dust, curing compounds, sealers, form release agents or any material that would prevent mortar from coming into contact with the open pores of the concrete. Shot blasting, sandblasting, chipping and high pressure water blasting (3,500 psi) are all excellent surface preparation methods. Smooth concrete surfaces may require etching with muriatic of sulfamic acid, then thoroughly cleaned with pressure washer.

Must prepare cured Mortartec Silicate DS with a light brush blast or high pressure (3000+ psi) water, with rotating nozzle prior to top coating to remove all surface efflorescence, curing agents, and laitance.

Application Method

NOTE: [The material will flash set if contaminated with calcium aluminate cement.] Ensure proper SSD prior to starting. Make sure all equipment for mixing, pumping, etc. are free from any calcium aluminate cement or products which contain calcium aluminate cement. Dampen area to achieve a saturated, surface dry condition (SSD). Apply in successive lifts to desired thickness. Use brush, float or trowel to achieve desired texture. Use only equipment specifically designed for dry schotcrete use only.

Film Thickness

Optimal build = 1/2″ –  4″, per pass.

Mortartec Silicate DS

Epoxytec Mortartec Silicate DS is “dry shotcrete” grade of high density, early strength cementitious mortar often used for industrial repair and restoration. With the early high strength curing properties, the mortar is also terrific for resurfacing prior to coating. The Mortartec Silicate DS provides a restoring and rebuilding mortar with strength and density suitable for aggressive environments.

High Density, Microsilica Restoring Mortar (for dry shotcrete use)

Epoxytec Mortartec Silicate DS is an excellent solution for general high build rebuilding, restoration, and resurfacing for infrastructure repair and coating contractors.  Reinforced with micro silica and fibers, the product has great high strength properties as a overlay to deteriorated substrates for rehab or for areas that may need to tolerate industrial abuse.  The system is specifically formulated to be applied by dry shot equipment for high build, up to 4″ in depth, per pass.
