Product description

BW6-9527 hand-applied modified polyurea thickened intermediate waterproof layer.

Solvent-free hand-applied modified polyurea used as a thickened intermediate layer for flooring, swimming pool and embedded waterproofing systems where compression resistance, impact resistance and durable waterproof protection are required.

What BW6-9527 delivers inside layered systems

Use BW6-9527 when a flooring, swimming pool or embedded waterproofing build-up needs a hand-applied thickened polyurea layer with dense film formation, strong bonding and resistance to water, alkali, impact and temperature change.

Thickened intermediate layerRecommended dry film thickness of 500-1000 µm supports added build in flooring and swimming pool waterproofing systems.
Pressure-resistant embedded waterproofingA seamless, tough and dense film supports concealed waterproof layers that sit under finish or protective systems.
Hand-scraped constructionDesigned for scraping application using puttying tools, supporting local detail work and system build-up control.
Strong concrete adhesionThe sheet lists concrete adhesion ≥3.0 MPa with substrate broken, supporting firm bonding to prepared mineral substrates.
Impact and compression-supporting layer50 kg·cm impact resistance helps the layer serve where floors, pools or embedded waterproofing assemblies need tougher intermediate protection.
Water, acid and temperature resistanceListed resistance data supports durable use below finish systems where water exposure and temperature variation must be considered.

Application scope

Typical use areas for BW6-9527.

BW6-9527 is used as a thickened intermediate polyurea layer in flooring and swimming pool systems, and as a pressure-resistant embedded waterproofing layer under finish or protective systems.

Flooring and pool system layers

Flooring thickened intermediate layerFor floor build-ups that need added polyurea thickness, impact resistance and durable waterproof protection below the finish layer.
Swimming pool waterproof intermediate layerFor pool assemblies where a dense hand-applied layer helps reinforce waterproofing beneath finish systems.
Thick protective layer under finishesUsed below finish or protective systems when a tougher intermediate waterproof layer is required.

Embedded waterproofing and build-up control

Pressure-resistant embedded waterproofing layerFor concealed waterproofing layers that need compression resistance and durable bonding to prepared concrete.
Quartz sand or talc powder additionAfter A/B mixing, the sheet allows adding quartz sand or talc powder and mixing again before use.
Impact and wear resistanceImpact resistance, collision resistance and wear resistance support tougher intermediate protection in demanding systems.
