What Each Layer Solves

The system separates concrete primer sealing, local surface repair, main spray membrane waterproofing and exposed surface protection, helping reduce substrate-related defects, leakage paths and surface durability risks in prepared water park and swimming pool projects.

BW8010 primer layer sealing concrete pool substrate absorption

BW8010 seals concrete and supports adhesion.

BW8010 is applied as the first primer to seal prepared concrete, reduce uneven absorption and support adhesion before the repair layer and main spray membrane are applied. It helps create a more stable bonding base for pool floors, walls and detail areas after proper substrate preparation.

BW8010 quartz sand leveling and repair layer for concrete pool surface

BW8010 + quartz sand repairs pores and uneven areas.

BW8010 blended with quartz sand forms a scrape-applied leveling and local repair transition layer. It helps fill pores, honeycombs, pits and local uneven areas before BW3-900 is sprayed, improving surface continuity without replacing the main waterproofing membrane.

BW3-900 spray polyurea main waterproofing membrane in a pool system

BW3-900 forms the main seamless waterproofing membrane.

BW3-900 forms the main continuous spray polyurea waterproofing membrane over the prepared and repaired concrete surface. It helps reduce leakage paths across pool floors, walls, splash zones, wall-floor transitions, inner corners, steps, drains, outlets, pipe penetrations and water play equipment bases.

BW0-8029 chloride-resistant exposed protective topcoat for pool waterproofing surface

BW0-8029 protects the exposed membrane surface.

BW0-8029 is applied as the exposed protective topcoat over the BW3-900 membrane. It helps improve surface durability, cleanability, UV resistance, color stability and maintainability for exposed water park and swimming pool waterproofing surfaces after pool-water exposure review.

How This System Helps Reduce Water Park and Pool Waterproofing Risks

Water park and swimming pool leakage often starts from small weak points: pores, honeycombs, pits, cracks, wall-floor transitions, inner corners, steps, drains, outlets, pipe penetrations, slide landing zones, splash zones and water play equipment bases. The BW8010 + BW3-900 + BW0-8029 system helps reduce these risks through a controlled route from concrete repair to seamless spray membrane formation and exposed-surface protection.

Concrete pool substrate preparation before BW8010 primer and spray polyurea waterproofing

01 Prepare the Concrete Pool or Water Park Substrate

Spray polyurea pool waterproofing starts with a solid, clean, dry and repaired concrete substrate. Remove weak concrete, laitance, dust, oil, standing water and loose areas, then review pool floors, walls, inner corners, drains, outlets, pipe penetrations, steps, slide landing zones, water play equipment bases, cracks, pores, honeycombs and pits before primer application.

02 Apply BW8010 as the First Primer

Apply BW8010 as the first primer to seal prepared concrete, reduce absorption differences and support adhesion before the quartz-sand repair layer. Primer coverage, substrate dryness and recoat condition should be controlled so the following repair layer and BW3-900 membrane are applied over a stable prepared surface.

03 Repair and Level with BW8010 + Quartz Sand

Use BW8010 blended with quartz sand for scrape-applied local repair and leveling. This repair transition layer helps fill pores, honeycombs, pits and uneven areas before BW3-900 is sprayed, but it should not be treated as the main waterproofing membrane.

04 Spray the BW3-900 Main Waterproofing Membrane

Spray BW3-900 as the main seamless waterproofing membrane over the prepared and repaired concrete surface. The membrane should continuously cover pool floors, walls, wall-floor transitions, inner corners, steps, drains, outlets, pipe penetrations, slide landing zones and water play equipment base details.
