Sauereisen SewerGard® Glaze No. 210GL is a protective coating specifically formulated for municipal wastewater environments. SewerGard Glaze provides a chemical-resistant barrier for concrete and steel. It may also serve as a sealing topcoat over other Sauereisen restorative materials and protective linings.

As a 100% solids epoxy polymer, SewerGard® Glaze No. 210GL is specified to protect infrastructure throughout the wastewater industry. Wherever corrosive conditions exist, No. 210GL may be used as a stand-alone, economical coating or as an extra measure of protection over textured underlayments. Applications range from manholes and lift stations within collection systems to tankage, structural steel and secondary containment at treatment plants.

Installation of SewerGard® Glaze is easily completed using airless spray equipment, plural component spray equipment, or roller.

CHARACTERISTICS

  • Resistant to hydrogen sulfide, sulfuric acid, MIC and treatment chemicals.
  • Suitable as a 15 - 40 mil or greater coating
  • Smooth surface aids washdowns and prevents debris accumulation.
  • Moisture tolerant to accommodate damp substrates.
  • Zero VOCs (100% solids) is a "Green", environmentally friendly coating system.
  • User-friendly application by airless spray equipment, plural spray equipment, or roller.

AREA PREPARATION

Temperature of Working Area
For optimum conditions, maintain a temperature of 60°-85°F on air, substrate, Liquid, and Hardener 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.

If temperatures are rising, it may be necessary to postpone the application or apply during cooler hours.

Surface Preparation
Metal - Abrasive blast to a nominal 2.5 mil profile employing SSPC-SP5 White Metal Blast for immersion and SSPCSP10 for other service conditions. An SSPC-SP6 Commercial Blast may be suitable for mildly corrosive atmospheric exposures. All welds must be continuous, free of flux and have a smooth rounded radius without any sharp edges.

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

New Concrete - All structures must have the necessary strength to withstand imposed loads during normal use and operation. Surface should be floated free of ridges or depressions and all voids filled with Sauereisen RestoKrete™ Substrate ReSurfacer No. F-121 or RestoKrete™ Filler Compound No. 209. The choice of underlayment will depend on the severity of the voids to be filled.

Surfaces should be made free of oil, grease, standing water, 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.

Old Concrete - Concrete must have the necessary strength to withstand imposed loads during normal use and operation. Mechanical methods should be utilized to remove old paints, protective coatings, and deteriorated concrete. Surfaces should be made free of oil, grease, standing water, and other contaminants that may inhibit bond. This can be
achieved by chemical cleaning.

Suitable surface preparation methods include shotblasting, abrasive blasting or water jetting. Restore the substrate as needed to provide an appropriate bonding surface. Stop active water leaks and repair cracks prior to the coating installation as well.

CONTROL JOINTS

Joints are to be placed over existing expansion joints, around all fixed objects, peripheries of rooms and all points of movement in the base slab. Consult Sauereisen for recommendations.

MIXING

For application by airless spray or roller:

Packaging consists of premeasured unitized containers of Hardener Part A and Resin Part B. Remix Part A and B 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.

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.

For Application by Plural A Component Spray: Premix hardener Part A and resin Part B separately before using.

INSTALLATION

Prior to application of SewerGard® Glaze, inspect the substrate for voids, bubbles, or defects that may result in blistering or pinholes in the topcoat. Repair with Sauereisen RestoKrete™ Substrate ReSurfacer No. F-121 or RestoKrete™ Filler Compound No. 209 Fast Set to ensure a sealed surface.

Roller application - Material should be delivered to finishers immediately after mixing. Do not let material remain in the mixing vessel. If application is for horizontal areas, spread the material with a squeegee to the desired thickness. To
improve the surface texture, lightly backroll the material with a short nap adhesive roller with a nondegradable core. For vertical applications, material shall be lightly backrolled to the desired thickness. All finishing and backrolling must be completed within 30 minutes from mixing.

Spray application - SewerGard® Glaze may be spray applied at a thickness of approximately 15-40 mils per coat or
greater depending on the spray equipment. 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. Recoat window is between 12 -24 hours at 70°F.

After No. 210GL has sufficiently cured, a holiday detector should be utilized to ensure a continuous pinhole-free lining. Consult a Sauereisen representative for details.

Any SewerGard® No. 210 System may be coated with a topcoat of No.210GL up to 24 hours after application. Consult Sauereisen's Technical Service Department for parameters specific to your application.

The following equipment is typically used for spray application:

Airless Spray Pumps - SewerGard® Glaze may be sprayed with a minimum 45:1 piston-primed, 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 surge tank.

Gun tip -Use Tip Housing Part No. XHD- 001 with Graco Reversa Tips MDL No. XHD with orifices of 0.025 to 0.031 inch tip works best. Alternative brand tips may be suitable, however, never use tips that contain a diffuser pin.

Material hose - 6' whip end, 3/8" i.d.; working pressure 5,000 psi, 16,000 psi burst.

Material hose - 0-25' overall, 1/2" i.d.; working pressure 4,000 psi, 16,000 psi burst.

Material hose - 25-75' overall, 3/4" i.d.; working pressure 4,000 psi, 12,000 psi burst.

Air compressor - 180 ft3 per minute at 100 psi, minimum.

Air hose from compressor - 3/4" to 1" i.d.: 100' maximum length to mastic pump.

Plural Component Spray Applications:
Mix Ratio (By Volume) 1 Part A-(Hardener) : 3.2 Parts B-(Resin)

Recommended equipment for plural component spray of Sauereisen SewerGard® No.210GL include WIWA and Graco variable ratio pumps (minimum 56:1). Examples include, but not limited to: WIWA Flexi-Mix, Graco Xtreme Mix, and Graco XM50.

For Plural Component Spray Applications preheating the resin and hardener is required to the following temperatures:

Part A Hardener - 80°-90°F
Part B Resin - 110°-120°F
