Sauereisen SewerGard - Model No. 210X - Protective Lining Specifically Formulated for Municipal Wastewater Environments
Sauereisen SewerGard® No. 210X is a protective lining specifically formulated for municipal wastewater environments. SewerGard® No. 210X provides a chemical-resistant barrier for concrete, masonry, brick, and steel substrates. As a 100% solids epoxy polymer No. 210X is specified to protect infrastructure throughout the wastewater industry. Wherever extreme corrosive conditions exist, No. 210X is used as a stand-alone lining. No. 210X is a high strength lining that enables high build capabilities. Applications range from manholes and lift stations within the collection systems to tankage, structural steel, digesters, clarifiers, and secondary containment at treatment plants. Installation of SewerGard® No. 210X is easily completed using airless or plural component spray equipment. No. 210X can be hand applied using a trowel, brush or roller.

Temperature of Working Area
For optimum conditions, maintain a constant temperature of 60°-85°F on air and substrate during application, and cure.
Keep substrate at 60°-80°F for at least 48 hours prior to application. The temperature and material must be at least 5°F above the dew point.
At temperatures below 60°F, the application becomes more difficult and curing is prolonged.
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. If temperatures are rising, it may be necessary to postpone the application and apply during cooler hours. It may be necessary to utilitize a primer to mitigate offgassing.
Metal - Abrasive blast to a minimum 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 or ground flat in accordance with SSPC/NACE Standard Practices.
Concrete - Refer to SSPC-SP13/NACE 6 'Surface Preparation of Concrete' guidelines. Surface should be profiled to an ICRI CSP 4-6 per ICRI 310.2.
For All Concrete Surfaces
Surfaces should be made free of oil, grease, and other contaminants that may inhibit bond. This can be achieved by chemical cleaning. Abrasive blast or high-pressure water blast concrete to remove laitance and obtain uniform surface texture exposing fine aggregate resembling sandpaper. Restore the substrate as needed to provide an appropriate bonding surface.
New & Old Concrete - Surface should be floated free of ridges or depressions and all voids shall be filled with an appropriate Sauereisen RestoKrete™ underlayment product. Mechanical methods should be utilized to remove old paints, protective coatings, and deteriorated concrete. This can be achieved by chemical cleaning. The choice of underlayment will depend on the severity of the voids to be filled.
Stop active water leaks with Sauereisen Insta-Plug™ No. F-180 or Hydroactive Urethane Grout No. F-370 prior to the coating installation. To asure material compatability, all voids should be filled with Sauereisen RestoKrete™ Substrate- Resurfacer No. F-121, Sauereisen RestoKrete™ Epoxy Modified Cement Mortar No. 208 or RestoKrete™ Filler Compound No. 209.
Consult Sauereisen for proper substrate restoration materials recommendation.
Mix only complete batches. Material which has begun to set must be discarded. Do not add any solvent, additive, or adulterant to any component or mixed material.
Application by Airless Spray
For optimum conditions, maintain a constant temperature of 60°-85°F on air and substrate.during application and cure. Keep substrate at 60°-80°F for at least 48 hours prior to application.
Packaging consists of premeasured unitized containers of hardener Part A and resin Part B.
Remix Part A by shaking can for 30 seconds and Part B by mechanical means for 2 minutes before combining. Completely empty contents of hardener Part A into resin Part B. Using a slow- speed ½-inch drill motor affixed with a 'Jiffy' type blade, mix three to five minutes until thoroughly blended and material temperature is a minimum of 65°F.
Airless Spray Application:
SewerGard® No. 210X may be spray applied at 40 - 65 mils per coat depending upon surface conditions, porosity, application technique, application equipment and exposure. Installation by airless spray should be done with a 50% overlap in a 'cross hatch' pattern to reduce the possibility of pinholes and to assure complete coverage. At temperatures above 85°F, the material working time decreases. Recoat window is up to 24 hours at 70°F as long as the material is capable of supporting itself.
The following equipment is typically used for spray application:
Airless Spray Pumps - SewerGard® No. 210X may be sprayed with a minimum 56:1 piston-primed, single stage airless pump such as the model formerly manufactured by Graco. Alternative equipment such as the Graco 56:1 King Piston Primed Airless, Model 236-477 is also suitable. The current specification is the Graco Xtreme Sprayer X60 - MDL#X60- DH4. Remove all filters including the filter from the surge tank.
Other pumps may be suitable, depending on the job site requirements.
Water Trap: - must be placed on the air line at least 50' from the air compressor.
Gun - Graco XTR-7 or equivalent. Remove all filters from gun before application.
Gun tip - Use Tip Housing Part No. XHD- 001 with Graco Reversa Tips MDL No. XHD with orifices of 0.019 to 0.025 inch tip works best. Alternative brand tips may be suitable.
Material hose - 6' whip end, 1/4' i.d.; working pressure 5,000 psi, 16,000 psi burst.
Material hose - 0-50' overall, 3/8' i.d.; working pressure 4,000 psi, 16,000 psi burst.
Air compressor - 180 ft3 per minute at 100 psi, minimum.
Application by Plural Component:
Temperature of Working Area
For optimum conditions, maintain a constant temperature of 60°-85°F on air and substrate during application, and cure. Keep substrate at 60°-80°F for at least 48 hours prior to application. The temperature and material must be at least 5°F above the dew point.
Premix Hardener Part A and Resin Part B separately before using.
Plural Component Spray Applications:
Mix Ratio (By Volume)
1 Part A-(Hardener) : 3 Parts B-(Resin).
Recommended equipment for plural component spray of Sauereisen SewerGard® No. 210X include variable ratio pumps or fixed ratio pumps 3 : 1 (fixed ratio) or variable ratio pumps with minimum ratio of 56 : 1, with recirculation and heating capabilities. It may be necessary to utilize heated hose lines and hoppers.
For plural component spray applications heating the resin and hardener to the following temperature is required. Preheating the material is also recommended.
Part A (Hardener) - 80° - 100°F
Part B (Resin) - 115° -125°F
Please consult Sauereisen for information and equipment required for spraying via plural component.
Sauereisen SewerGard® No. 210X is a 100% solids epoxy with zero shrinkage. The dry film thickness (DFT) is expected to be the same as the wet film thickness (WFT). Depending on the type of application equipment and service conditions, SewerGard® No. 210X can be applied at 40 - 65 mils per coat.
Note: The application thickness and the number of coats required to achieve the specified thickness may vary with surface conditions, application method and exposure.
In applications where spray method is not feasible or it is prohibited, No. 210X can be applied by trowel, brush or roller method at a maximum of 12 mils per lift.
