Application stages

How This System Helps Reduce Wastewater Tank Corrosion Risks

Wastewater tank anti-corrosion risks often come from concrete pores, honeycombs, bug holes, wall-floor corners, pipe penetrations, inlet and outlet areas, sedimentation zones, immersion exposure, corrosive wastewater, pH variation, cleaning chemicals, humid corrosive vapor, weak repair zones and coating pinholes. This system uses BW8010 primer and quartz-sand repair support before BW3-951 is spray-applied as the main anti-corrosion protective lining to help improve adhesion, surface continuity and corrosion protection on prepared concrete wastewater structures.

Concrete wastewater tank surface preparation before anti-corrosion protection
01

Substrate Requirements

Concrete wastewater tank substrate should be solid, clean, dry and stable. Loose concrete, laitance, dust, oil, standing water, weak surface layers and contaminated areas should be removed before primer application.

Reference: confirm surface strength, dryness, cleanliness, contamination removal, detail repair scope and coating readiness before primer application.
02

BW8010 Concrete Primer

Apply BW8010 as the concrete primer to seal capillary pores, improve adhesion and reduce absorption differences before repair leveling and anti-corrosion coating.

System reference: about 100 um / about 0.20 kg/m2 from BW8010 product data. Final primer consumption depends on concrete porosity, absorption and surface condition. BW8010 Solvent-Free Polyurea Primer official product packaging image Product usedView BW8010 ->

Suitable conditions

Suitable Wastewater Structure Conditions

Use this section to check whether the project fits a BW8010 primer / repair layer + BW3-951 spray polyurea anti-corrosion system before final specification.

  1. 01

    Wastewater Treatment Basins

    Treatment basins can be reviewed when concrete sealing, defect repair and anti-corrosion protection are required.

    Check before specification: pores / repair / corrosive exposure

  2. 02

    Equalization and Sedimentation Tanks

    Tank interiors can be reviewed when immersion and corrosive media exposure drive coating selection.

    Check before specification: immersion / media / DFT

  3. 03

    Aeration Tanks and Channels

    Channels and aeration zones need continuous protection when water flow, chemical exposure and surface wear are present.

    Check before specification: flow / chemical exposure / wear

FAQ

FAQ About Wastewater Tank Anti-Corrosion Protection

Common questions about using BW8010 and BW3-951 for wastewater tank anti-corrosion protection.

What is this spray polyurea wastewater tank anti-corrosion system used for?

It is used for prepared concrete wastewater basins, sewage tanks, treatment tanks, wastewater channels and chemical collection pits that require spray polyurea anti-corrosion protection under immersion, corrosive wastewater and pH variation conditions.

What role does BW8010 play in this system?

BW8010 is used as the concrete primer. It seals capillary pores, improves adhesion and helps control surface absorption before quartz-sand repair and BW3-951 application.

Why is BW8010 blended with quartz sand?

BW8010 can be blended with quartz sand for pore filling, honeycomb repair, bug hole treatment, scrape leveling and local defect repair before the main spray polyurea anti-corrosion lining is applied.

Which product forms the main anti-corrosion lining?

BW3-951 forms the main spray polyurea anti-corrosion protective lining in this wastewater tank system. BW8010 and the quartz-sand repair layer support adhesion and surface continuity but are not the main anti-corrosion lining.

What wastewater tank details need special attention?

Wall-floor corners, pipe penetrations, inlet and outlet areas, sedimentation zones, wastewater channels, chemical collection pits, cracks, honeycombs, bug holes and local weak concrete should be checked before coating work.

Can the exact repair layer thickness be fixed before inspection?

No. The BW8010 quartz-sand repair / leveling layer is project-specific because thickness and consumption depend on pores, honeycombs, pits, void depth and repair scope.

What film thickness is recommended for BW3-951?

BW3-951 product data lists a recommended film thickness range of 1000-3000 um. For this spray polyurea wastewater tank anti-corrosion system, BW3-951 is recommended at about 1.5 mm as the main anti-corrosion protective lining. Final thickness should be confirmed according to wastewater chemistry, immersion condition and project specification.

What information is needed before specifying the system?

Share the structure type, concrete condition, repair scope, wastewater composition, pH variation, immersion condition, cleaning method, target DFT, operating temperature and inspection requirements before final selection.
