A hand-applied waterproofing system for prepared concrete tanks, swimming pool basins and selected water-retaining concrete structures where spray equipment is not convenient. It helps build a continuous polyurea waterproofing membrane over repaired concrete surfaces, with a protective topcoat for exposed pool or tank service conditions after water-chemistry review.
Concrete primer repair + hand-applied polyurea waterproofing membrane + exposed protective topcoat
Concrete sealing, adhesion support and local quartz-sand repair base
Main continuous hand-applied waterproofing membrane
Exposed protective topcoat for pool, tank and outdoor surface durability review
The system separates concrete preparation, main waterproofing and exposed surface protection, helping reduce substrate-related defects, leakage paths and surface durability risks in prepared concrete tanks and swimming pools.
BW8010 seals prepared concrete, reduces uneven absorption and supports adhesion before the main membrane is applied. Where needed, it can be blended with quartz sand for local pore filling, honeycomb repair, scrape leveling and uneven surface correction around tank or pool substrates.
BW6-9528 forms the main continuous hand-applied polyurea waterproofing membrane over the prepared concrete surface. It helps reduce leakage paths around wall-floor transitions, inner corners, steps, drains, pipe penetrations, outlets and other detail areas that require continuous coverage.
BW0-8029 is applied as the exposed protective topcoat over the BW6-9528 membrane. It helps improve surface durability, cleanability, weather resistance, color stability and maintainability for exposed tank or pool waterproofing surfaces after water-exposure review.
Tank and swimming pool leakage often starts from small weak points: pores, honeycombs, pits, cracks, wall-floor transitions, inner corners, steps, drains, outlets, pipe penetrations and repaired patches. The BW8010 + BW6-9528 + BW0-8029 system helps reduce these risks through a controlled route from concrete repair to membrane continuity and exposed-surface protection.
Concrete tank and pool waterproofing starts with a solid, clean, dry and repaired substrate. Remove weak concrete, dust, oil, standing water and loose areas, then review wall-floor transitions, inner corners, drains, pipe penetrations, steps, cracks, pores, honeycombs, pits and repair patches before coating work begins.
BW8010 helps seal prepared concrete, reduce surface absorption and support adhesion before the main membrane. Where needed, it can be blended with quartz sand for local pore filling, honeycomb repair, scrape leveling and uneven concrete correction around tank or pool details.
BW6-9528 forms the main continuous hand-applied waterproofing membrane over the prepared concrete surface. This layer should maintain continuous coverage across tank or pool floors, walls, wall-floor transitions, inner corners, steps, drains, outlets, pipe penetrations and repaired detail zones.
BW0-8029 is applied over the BW6-9528 membrane as the exposed protective topcoat. It helps support surface durability, cleanability, color stability, UV or weather resistance and pool or tank service review when the waterproofing surface remains exposed.
System-relevant values for concrete tanks and swimming pools: concrete adhesion, membrane flexibility, water retention and exposed water-contact surface durability.

The above values are selected from the current product-detail Product Information, Physical Properties and Chemical Resistance tables. Final film thickness and suitability should be confirmed according to substrate condition, service exposure, detail design, project specification and the latest approved technical data sheet. Chemical or water-contact suitability should be confirmed according to actual medium composition, concentration, pH, temperature, contact time, cleaning method and maintenance procedure.
Before immersion or regular service, key inspection should focus on concrete readiness, BW8010 repair condition, BW6-9528 membrane continuity and BW0-8029 exposed topcoat quality.
Confirm the concrete surface before coating work starts.
Review the repair base and main hand-applied waterproofing membrane before topcoat application.
Check the exposed topcoat before immersion or regular service.
Use these checks to judge whether the BW8010 + BW6-9528 + BW0-8029 system is suitable before final specification.
For prepared concrete tanks where surface strength, moisture condition, cleaning quality and detail preparation can meet hand-applied membrane requirements. Key review: concrete tank, moisture and detail preparation.
For swimming pool basins or repair zones with pores, honeycombs, pits, cracks or uneven concrete that need local repair before the main waterproofing membrane is applied. Key review: pool basin, repair zones and leveling.
For wall-floor transitions, inner corners, steps, drains, outlets, pipe penetrations and equipment bases where continuous hand application is useful. Key review: corners, drains and penetrations.
For projects where large spray equipment access, overspray control or site conditions make hand application more practical. Key review: hand application, access and small spaces.
For exposed pool or tank surfaces where water chemistry, UV exposure, color finish, cleanability and topcoat durability need to be reviewed before final specification. Key review: water chemistry, UV exposure and topcoat.
Do not treat the BW8010 quartz-sand repair layer or BW0-8029 topcoat as the main waterproofing membrane. The main continuous waterproofing layer in this system is BW6-9528 hand-applied polyurea. Final system selection should confirm concrete condition, moisture, repair scope, water chemistry, chlorine or disinfectant exposure, temperature, target membrane thickness, topcoat design and inspection requirements before ordering.
