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® 210RS is a rotary spray-applied material specifically designed to protect concrete and steel surfaces of municipal wastewater treatment structures from chemical attack and physical abuse. The application properties of 210RS permit economical protection of new and rehabilitated substrates.


  • Resistant to corrosive conditions common to municipal wastewater treatment industry.
  • Suitable for application over damp or dry concrete surfaces.
  • Spray applied. for new construction.
  • Available in Hot and Cold Weather formulations. Contact Sauereisen.

When cured, 210RS 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.


Temperature of Working Area
Maintain a temperature of 65°-85°F on air, substrate, Liquid, and Hardener components during mixing, application and cure.

The monolithic components and substrate 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 85°F, the material working time decreases. It is recommended that the material components be stored in a cooler area prior to mixing.

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. 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.

High-pressure waterblasting is recommended prior to the material application. Equipment such as the Manhole MasterTM by WaterBlasters, Inc. can be used to quickly and effectively remove debris and to obtain a suitable bonding profile.

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

The waterblast pump should have capability of 5000 psi pressure and 15-20 gallons of water per minute. An alternative is to employ a Jetter truck with a capacity of 2000-2500 psi and 50-80 gallons per minute.

Concrete - All structures must be properly designed, structurally sound, and capable of withstanding imposed loads.

Substrate surfaces requiring repairs should be resurfaced with Sauereisen RestoKrete™ Underlayment F- 120, RestoKrete™ Substrate Resurfacer F-121 or RestoKrete™ Filler Compound 209 depending on severity of repairs 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 should be regrouted with appropriate Sauereisen mortar to ensure structural integrity of the manhole.

All active hydrostatic leaks must be repaired with either Sauereisen InstaPlug F-180 or Hydroactive Polyurethane Grout F-370 prior to SewerGard® 210RS application.

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.

Metal - Abrasive blast to a nominal 2.5-mil profile employing SSPC-SP5 White Metal Blast for immersion and SSPCSP10 for other service conditions. All welds must be continuous, free of flux and have a smooth rounded radius without any sharp edges.


210RS 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.

210RS is applied through specialized rotary spray equipment and applied at a thickness of 60-125 mils. This is done from street level with minimal entry into manhole. Consult Sauereisen for appropriate rotor-stator, carousel, or airless pumps.

After the 210RS has sufficiently cured, a holiday detector should be utilized to ensure a continuous pinhole-free lining. A Sauereisen SewerGard® Patch Kit may be used to conveniently repair any pinholes. Consult a Sauereisen representative for details.

Backrolling with a damp short nap mohair roller can be done to improve aesthetics.

SewerGard® 210RS may be topcoated with SewerGard® 210G from 12- 24 hours at 70°F.


210RS: 50 ft2 per unit at 125 mils.
Coverage is theoretical and will vary depending upon surface conditions, porosity, application techniques and specific project conditions.


SewerGard® 210RS may be exposed to a chemical environment in approximately 17 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.

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


All equipment should be cleaned with Sauereisen PumpClean 813 before material cures. If removal is required after cure consult Sauereisen for specific recommendation.


Sauereisen SewerGard® 210RS has a shelf life of one 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.
