Application Stages

How This System Helps Reduce Tank and Pool Waterproofing Risks

Tank and swimming pool waterproofing risks often appear around wall-floor transitions, inner corners, drains, pipe penetrations, steps, cracks, pores, honeycombs and pits. Long-term immersion, pool water, chloride-containing water exposure and surface wear also require attention after the main waterproofing membrane is applied. This system uses BW8010 primer / repair base, BW6-9528 hand-applied polyurea membrane and BW0-8029 protective topcoat to help prepare the concrete base, form a continuous hand-applied waterproofing membrane and support surface protection under tank and pool service conditions.

Concrete tank and swimming pool substrate preparation before BW8010 leveling repair and hand-applied polyurea waterproofing
01

Concrete Tank / Pool Substrate Preparation

Prepare the concrete tank or pool substrate by removing weak material, dust, oil and loose areas, then review pool floor and wall transitions, inner corners, drains, pipe penetrations, steps, cracks, pores, honeycombs, pits and repair patches before coating work.

Reference: remove weak concrete, dust, oil, standing water and loose areas before BW8010 application. Confirm repair scope around drains, pipe penetrations, inner corners and cracks.
02

BW8010 Quartz Sand Leveling / Repair Layer

Use BW8010 to seal prepared concrete, reduce absorption and support adhesion. Where needed, BW8010 can be blended with quartz sand for local repair preparation around pores, honeycombs, pits, cracks, inner corners and uneven tank or pool surfaces before the main membrane is applied.

Reference: BW8010 can be used for substrate sealing and, when blended with quartz sand, local pore filling, honeycomb repair and leveling preparation. Thickness and consumption are project-specific.

BW6-9528 Hand-Applied Polyurea Main Waterproofing Membrane

Apply BW6-9528 by brush, roller or compatible hand-application method to form the main continuous hand-applied waterproofing membrane. It helps create a flexible, high-strength layer across wall-floor transitions, inner corners, drains, pipe penetrations, steps and other tank or pool detail zones that need continuous coverage.

Reference: about 1.5 mm membrane thickness / about 2.25 kg/m2. Confirm continuous coverage around wall-floor transitions, drains, pipe penetrations, steps and corners.

BW0-8029 Protective Polyaspartic Topcoat

Apply BW0-8029 as the protective topcoat over the BW6-9528 main waterproofing membrane to support pool water exposure, chloride-containing water exposure review, surface wear resistance, cleanability and UV or weathering resistance when the surface is exposed.

Reference: recommended 30-60 um per coat; tank and pool total topcoat design may be specified as 60-120 um depending on water exposure and number of coats. BW0-8029 Two-Component Polyaspartic Protective Topcoat official product packaging image Product usedView BW0-8029 ->

Suitable project conditions

Suitable Tank and Swimming Pool Conditions

Use this section to check whether the project fits a BW8010 + BW6-9528 + BW0-8029 hand-applied waterproofing and protection system before final specification.

  1. 01

    Small and Medium Concrete Tanks

    Concrete tanks can be reviewed when surface strength, moisture condition, cleaning and detail preparation are ready for leveling repair and membrane work.

    Check before specification: strength / moisture / cleaning

  2. 02

    Swimming Pool Repair Areas

    Repair zones with pores, honeycombs, pits or local unevenness can use BW8010 quartz-sand leveling before the main hand-applied membrane.

    Check before specification: pores / honeycombs / leveling

  3. 03

    Equipment-Limited Sites

    Projects where large equipment access is limited can be reviewed for brush, roller or compatible hand-application workflow.

    Check before specification: access / ventilation / workflow

  4. 04

    Pool Water Exposure Review

    Use BW0-8029 as the final exposed protective topcoat when the surface needs pool water, chloride-containing water exposure, UV, weathering and color-retention review.

    Check before specification: pool water / UV / color retention

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.

FAQ

FAQ

Common questions about using BW8010, BW6-9528 and BW0-8029 for hand-applied tank and swimming pool waterproofing.

What is this tank and swimming pool waterproofing system used for?

It is designed for prepared concrete tanks, swimming pools, pool basins and water-retaining concrete structures where a hand-applied polyurea waterproofing system is more practical than spray equipment.

What does BW8010 do in this system?

BW8010 is used for concrete substrate sealing, adhesion support and local repair preparation. When blended with quartz sand, it can help adjust pores, honeycombs, pits and local uneven areas before membrane application. It is not the main waterproofing layer.

Which product forms the main waterproofing membrane?

BW6-9528 forms the main hand-applied polyurea waterproofing membrane in this system. It is the continuous waterproofing layer between the BW8010 preparation layer and the BW0-8029 protective topcoat.

What is the recommended BW6-9528 membrane thickness for this tank and swimming pool system?

BW6-9528 is the main hand-applied polyurea waterproofing membrane in this system and is recommended at about 1.5 mm. Final membrane thickness should be confirmed according to tank or pool structure, substrate condition, water exposure and project specification.

What role does BW0-8029 play in pool water exposure?

BW0-8029 is the protective polyaspartic topcoat. It supports surface protection for pool water, chloride-containing water exposure and UV or weathering review when exposed, but it does not replace the BW6-9528 membrane.

Which tank or pool details need special attention?

Wall-floor transitions, corners, drains, pipe penetrations, steps, overflow details, outlets and equipment bases should be checked and treated according to project detail requirements before the main membrane is applied.

Why use a hand-applied polyurea system instead of spray polyurea?

Hand application is useful for smaller tanks, swimming pool repair areas, detail-rich spaces and projects where spray equipment access, overspray control or site conditions make spray application less convenient.

How should the quartz-sand repair layer be specified?

The BW8010 quartz-sand repair or leveling layer should be confirmed according to concrete pores, honeycombs, pits, local unevenness and repair depth. Its thickness and consumption are project-specific.

What should be checked before application?

Check concrete strength, moisture condition, dust, oil contamination, loose areas, cracks, honeycombs, surface flatness, detail geometry, material compatibility, target membrane thickness and topcoat finish requirements.

What is the expected service life of this waterproofing coating system?

Based on laboratory testing and practical project verification, this waterproofing coating system is designed to support up to 20 years of service life when properly installed on suitable concrete substrates and maintained according to project requirements.
