Physical properties were determined on specimens prepared under laboratory conditions using applicable ASTM procedures. Actual field conditions may vary and yield different results; therefore, data is subject to reasonable deviation.

Sauereisen SewerGard® Industrial No. 210TN is an aggregate-filled, NovolaK epoxy material. This lining system is specifically designed to protect concrete surfaces of industrial wastewater treatment structures and collection systems from chemical attack and physical abuse.

SewerGard® No. 210TN's non-sagging application properties permit economical repair and protection of vertical, horizontal and overhead surfaces of either new or rehabilitated substrates.

When cured, No. 210TN provides an impermeable, high strength, corrosion-resistant lining for manholes, lift stations, grit chambers, aeration basins, and related structures subject to infiltration and attack from hydrogen sulfide and acid generated by microbiological sources.

CHARACTERISTICS

  • NovolaK epoxy formulation resistant to the most corrosive municipal and industrial wastewater environments.
  • Suitable for application over damp or dry concrete surfaces.
  • Trowelable, non-sagging consistency ensures ease of application on vertical and overhead surfaces.
  • Does not require a primer.
  • Prohibits water infiltration.
  • Standard Color - Light Gray (50).

AREA PREPARATION

Temperature of Working Area
Maintain a temperature of 60°-85°F on air, substrate, Liquid, Hardener, and Powder components during mixing, application, and cure.

The monolithic components should be maintained at 65°F to 80°F for 48 hours prior to beginning work.

At temperatures below 65°F, the application becomes more difficult and curing is retarded. Above 80°F, the material working time decreases.

Application in direct sunlight and rising surface temperature may result in blistering of the materials due to expansion of entrapped air or moisture in the substrate. Concrete surfaces that have been in direct sunlight must be shaded for 24 hours prior to application and remain shaded until the initial set has taken place. In rising temperatures it may be necessary to postpone the application or apply during cooler hours.

Surface Preparation
Surfaces should be made free of oil, grease, water, and other contaminants that may inhibit bond. This can be achieved by chemical cleaning.

Concrete - Refer to SSPC-SP13/NACE 6 "Surface Preparation of Concrete" for detailed guidelines.

New Concrete - All structures must be properly designed and capable of withstanding imposed loads. Abrasive blast,
high-pressure water blast, or acid etch concrete to remove laitance and obtain uniform surface texture. After surface preparation, voids left in concrete surface must be filled with Sauereisen Filler Compound No. 209.

Old Concrete - Concrete must be dry, firm and structurally sound as specified by the architect/engineer. Mechanical methods should be utilized to remove old paints, protective coatings, and attacked or deteriorated concrete. Abrasive blast or high-pressure water blast concrete to remove laitance and obtain uniform sound substrate.

Substrates requiring repairs in excess of 1/8-inch depth should be resurfaced with Sauereisen Underlayment No. F-120 to ensure proper rehabilitation of the substrate.

Brick - Abrasive blast or high-pressure water blast all foreign particles and attacked or unsound mortar from the joints. Loose brickwork or open joints should be regrouted with appropriate Sauereisen mortar to ensure structural integrity.

All active hydrostatic leaks must be stopped with Sauereisen materials such as InstaPlug No. F-180 or Hydroactive Urethane Grout No. F-370 prior to SewerGardTM Industrial No. 210TN application.

If chemical cleaning is utilized to remove contaminants, substrate must be neutralized. If abrasive or high-pressure water blasting is used as the method of surface preparation, all sand and/or debris must be removed by thoroughly vacuuming the area with an industrial vacuum cleaner. If surface does not have desired conditions, repeat surface preparation procedure.

No. 210TN may be applied over damp surfaces that are free of standing water; best results are achieved with dry surfaces.

APPLICATION

Mixing
SewerGard® Industrial No. 210TN is packaged in pre-measured units of Powder, Liquid, and Hardener components. Mixing should be done mechanically with a "Jiffy" mixer blade chucked into a drill motor. The mixing equipment must be clean and free of Portland cement or other contaminants.

Remix both Liquid and Hardener prior to combining components. Empty contents of the Liquid into a clean, dry mixing container. Empty contents of Hardener into Liquid and mix thoroughly until blended for at least one minute. Add Powder component gradually while mixing to a uniform consistency.

Mix only complete batches. Material which has begun to set must be discarded. Do not try to retemper the material. Do not add solvent, additive or adulterant to any component or mixed material.

Remove the entire batch from the mixer when mixing is completed to prevent build-up in the equipment. While pouring one batch, another should be mixed in order to eliminate delays and to permit continuous operation.

Installation
SewerGard® No. 210TN is applied by trowel at a minimum 1/8 inch thickness. Theoretical coverage is 35 ft2 per unit at the thickness of 1/8 inch. Actual coverage may vary, depending upon jobsite conditions. Screed bars may be used to control thickness on large surface areas.

To provide a pinhole-free surface and removal of trowel marks in No. 210TN, a short-nap mohair paint roller slightly dampened with water may be used. Excess water should be shaken off prior to backrolling.

After SewerGard® No. 210TN has achieved a hardened surface, a holiday detector should be utilized to ensure a continuous pinhole-free lining. A SewerGard Patch Kit may be used to conveniently repair any pinholes. Consult Sauereisen for details.

For details regarding construction joints, protrusions or penetrations through concrete, consult Sauereisen for specific recommendations.

COVERAGE

No. 210TN 35 ft2 per unit at 1/8 inch.
*Coverage is theoretical and will vary depending upon surface conditions, porosity, application techniques and specific project conditions.

SETTING/CURING

SewerGard® Industrial No. 210TN will have an initial set in approximately 18 hours and can resist standing water or sewage shortly thereafter. Aggressive or turbulent flow that may inhibit film formation or displace materials while curing will result in poor bond to the substrate. Consult Sauereisen for parameters specific to your application.

PACKAGING

No. 210TN is packaged as a 44.7-pound unit with Hardener, Liquid, and Powder components included within a pail.
*Containers are filled by weight, not volume. Container size does not indicate volume of contents.

CLEAN-UP

All equipment should be cleaned with MEK before material cures. If removal is required after cure consult Sauereisen for specific recommendation.

SHELF LIFE

Sauereisen SewerGard® Industrial No. 210TN has a shelf life of one (1) year, when stored in unopened, tightly sealed containers in a dry location at 70°F. Avoid freezing. If there is a doubt as to the quality of the materials, consult a Sauereisen representative.

CAUTION

Consult Safety Data Sheets and container label Caution Statements for hazards in handling these materials.
