CPP Sprayliner MH
CPP Sprayliner MH has been designed to spray-on line and rehabilitate sanitary sewer collection system assets, and other underground, cylindrical and/or small box structures in contact with H2S and in need of I&I mitigation with sealed lining. CPP Sprayliner MH performs in areas subject to chemical attack, and as a sealer preventing oxidation while holding back water migration, inflow/infiltration (I&I), and hydrostatic pressure. Ideally suited as a protective coating/lining solution for:
- Concrete repair and protection
- Applied liner
- Structural lining
- Ultra high moisture, wet solution
- Sanitary sewer collection rehab/lining (ie- manholes, lift stations, pipe, etc.)
Concrete (other brick or masonry): Prepare the concrete by abrasive blasting, high pressure water cleaning or jetting, and/or other approved methods to achieve clean, sound, and profiled concrete (min. ICRI CSP-3) in accordance with SSPC-SP 13 / NACE No. 6. “Surface Preparation of Concrete.” NOTE: Epoxytec CPP™ Sprayliner™ MH can be applied direct to concrete (DTC), self-priming. However, should an abnormal or conditional situation exist (ie- outgassing, MVT, etc), primers and/or resurfacers (although optional) may assist, and may be recommended.
Steel: Inspect and remove oil, grease, chlorides or other contaminants – “Solvent Cleaning” (SSPC-SP1) may be required. Abrasive blasting (or other approved mechanical methods) SSPC-SP10 / NACE 2, “Near-White Blast Cleaning,” must be administered in order to achieve a clean surface with a minimum profile of 100 microns (4 mils); remove dust and debris by high compressive air or solvent cleaning (SSPC-SP1) may be required again. Before preparing or applying on steel, verify that the temperature of the surface is at least 3 degrees C (5 degrees F) from the dew point temperature to preclude condensation. NOTE: Epoxytec CPP™ Sprayliner™ MH can be applied direct to metal (DTM), self-priming. However, should an abnormal or conditional situation exist or if a “holding” primer is needed to prevent flash rusting, consider the use of an Epoxytec recommended primer.
NOTE: Methods outlined herein, are a min. basis of design of generalized guidance. Various detailed CSI-formatted project design specs are available for download at epoxytec.com, and/or consult with Epoxytec for other specific design considerations.
Epoxytec CPP Sprayliner MH is designed to be sprayed utilizing specialized equipment, specified, proven and sold by approved equipment vendors of Epoxytec. Requires fully heated, plural component system with recirculating and agitating heated hoppers up to 150F, with heated hoses. Mixing occurs in a static chamber prior to a single whip hose; and must have purging capability through the mixing chamber, the whip hose and spray gun. Purge and clean with Epoxytec Cut 5 solvent. The system must be fixed ratio of 1:1 by volume with a minimum of 25 gallon preheating holding capacity for each part of material. NOTE: Epoxytec limits the sale of Epoxytec CPP Sprayliner MH until all equipment and know-how is validated by one of Epoxytec’s certified equipment vendors and consultants. In addition, Epoxytec only recommends certain approved vendors to validate the equipment and know-how prior to fulfilling any production or sales order. For detailed spray equipment specifications, heating, pressure, power, hose specs, purging/cleaning requirements or designs- contact Epoxytec for a list of Epoxytec CPP Sprayliner MH certified equipment vendors/distributors.
CPP Sprayliner MH can be applied as a single coat or multi-coat system. As a protective liner, CPP Sprayliner MH can be applied at a minimum of 1/16” (~60 mils). As a reinforcement liner or for more severe conditions, CPP Sprayliner MH is recommended at a minimum 125 mils. Maximum build-up per coat is 3/8” (375 mils) without sag per coat, depending on temperature. For applications requiring thicker lining, multiple passes may be utilized.
Note: For fully deteriorated structures, where fully structural design is required, various structural design criteria will need to be calculated for proper thickness design recommendations.
Epoxytec CPP Sprayliner MH is a 100% solids, high build structural grade amine epoxy lining formulated specifically for rehab and lining of sanitary sewer collection systems (manholes, cylindrical lift stations, pipe). High moisture tolerance, with H2S resistance and sealed I&I barrier protection.
Similar to “standard” CPP once cured, this version is packaged more conveniently for applicators seeking to spray with heated plural-component equipment. The material can be sprayed ultra-high build, up to 3/8” (375 mils) per pass. Blended with reinforcing agents and various fibers, the Epoxytec CPP Sprayliner MH when cured creates reinforcement lining as a fiber-reinforced-polymer (FRP), with high strength and flexural properties for partially or fully deteriorated structures
