Sauereisen SewerGard - Model Industrial No.210GLN - Chemically Resistant, Epoxy NovolaK Coating System
SewerGard Industrial No.210GLN is a chemically resistant, 100% solids, epoxy NovolaK coating system. It is used as a topcoat for Sauereisen SewerGard Industrial systems or as a coating to protect concrete and steel from chemical attack. SewerGard Industrial No.210GLN may be used in many kinds of aggressive industrial wastewater environments. It is specifically formulated as a sealer to resist strong oxidizing environments, especially high concentrations of sulfuric acid. This material can be applied by roller or spray and provides an economical protective barrier against processing chemicals and higher temperatures. No.210GLN system utilizes Sauereisen ConoWeld No. 501 as a bond-enhancing primer for direct applications over concrete and steel.
- Excellent resistance to sulfuric acid.
- Designed for ultra-aggressive industrial wastewater environments.
- Easy to clean surface.
- Standard Color - Light Gray (50).
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. In rising temperatures it may be necessary to postpone the application or apply during cooler hours.
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.
Concrete - Refer to SSPC-SP13/NACE 6 'Surface Preparation of concrete' for detailed guidelines.
Surfaces should be free of oil, grease, water, and other contaminants that may inhibit bond. This can be achieved by chemical cleaning.
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 Underlayment No. F-120 or No. 209 Filler Compound. The choice of underlayment will depend on the severity of the voids to be filled. Surfaces should be sloped a maximum 1/4 inch per foot for drainage.
Abrasive blast, high-pressure water blast, or acid etch concrete to remove laitance and obtain uniform surface texture exposing fine aggregate resembling coarse sandpaper.
Old Concrete - Concrete must be dry, firm and 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.
Abrasive blast, high-pressure water blast, or acid etch concrete to remove laitance and to obtain a uniform, sound substrate.
All prepared surfaces must be allowed to dry prior to the coating application. Regardless of preparation method used, all surfaces must be vacuumed to remove any loose deposits or contamination.
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.
ConoWeld No. 501 is the epoxy primer recommended for metal, concrete and other porous substrates. Apply ConoWeld prior to the SewerGardTM Industrial No.210GLN installation to enhance bond strength.
Primer - ConoWeld primer is supplied in premeasured containers. Remix individual containers before using.
Packaging of Primer No. 501 consists of Hardener Part A and Resin Part B which must be mixed together. Completely empty contents of Hardener Part A into Resin Part B container. Using a slow-speed ½-inch drill motor with a 'Jiffy' type blade, mix thoroughly until blended for three minutes. Primer is ready for use immediately after mixing.
SewerGardTM Industrial No. 210GLN 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.
Primer - Apply primer to concrete or steel using either a short nap adhesive roller with a nondegradable core, or a nylon bristle brush. For horizontal applications, pour primer onto the surface and spread with a squeegee before backrolling or brushing.
ConoWeld may also be sprayed using airless spray equipment. Typical application thickness is 5-10 mils. Consult Sauereisen for specific details.
Prior to application of the Sauereisen SewerGardTM Industrial No.210GLN, inspect the primed surface for voids, bubbles or defects that may result in blistering or pinholes in the lining. Repair with Sauereisen Filler Compound No. 209 Fast Set to ensure a sealed surface.
SewerGard® Industrial No. 210GLN
Roller application - Material should be delivered to finishers immediately after mixing. Do not let material remain in the mixing vessel.
If application is for floor areas, spread the material with a squeegee to the desired thickness. To improve the surface texture of floor applications, lightly backroll the material with a short nap adhesive roller with a nondegradable core. For vertical application, material shall be lightly backrolled to desired thickness. All finishing and backrolling must be completed within 30 minutes from mixing.
Spray application - SewerGardTM Industrial No.210GLN may be spray applied at a thickness of approximately 10 mils per coat. 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 times shall not exceed 24 hours at 70°F.
Measures such as water traps, dryers, or filters should be used to prevent pump freeze up.
After SewerGardTM Industrial No.210GLN has sufficiently cured, a holiday detector should be utilized to ensure a continuous pinhole-free lining. Consult a Sauereisen representative for details.
The following equipment is typically used for spray application:
Mastic pump - No.210GLN may be sprayed with a 45:1 piston-primed, airless pump such as the model formerly manufactured by Graco. The current specifications for new equipment are the Graco 56:1 King Piston Primed Airless, Model 236-477. Remove filter from surge tank. Other pumps may be suitable, depending on job site requirements.
Moisture Air Dryer - RFI Model DA-300 or equivalent. Moisture air dryer must be placed at least 50' from air compressor on air line.
Gun - Graco Pistol-Grip Flo Gun, Model 224-991.
Gun tip - For fiber-filled linings, use a Graco Reverse-a-CleanTM housing part No. 222-674 with an orifice of 0.039 to 0.043 inches. For unreinforced coatings, the 0.039-inch tip works best. In either case, the diffuser should be removed prior to use.
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.
