FAQ

FAQ about BW6-9526 hand-applied thick-film polyurea waterproof coating.

These answers follow the BW6-9526 source data sheet and support contractor review before ordering.

Does BW6-9526 require a specialized polyurea spray machine?

No. The data sheet states that BW6-9526 can be applied by scraper and does not require specialized polyurea spraying equipment, which is the main reason it is positioned for hand-applied thick-film repair work.

What is the recommended dry film thickness for BW6-9526?

The application guide lists a recommended dry film thickness of 500-1000 micrometers, or the project design requirement if a different build is specified.

Where is BW6-9526 typically used?

The data sheet lists waterproofing and repair work in construction, water conservancy, transportation, chemical and power plant projects, including highway, pavement and airport runway crack repair, dam and coastal embankment leakage repair, and harbor or dock maintenance.

What substrate preparation does BW6-9526 need?

For metal, the Chinese sheet recommends abrasive blasting to Sa2.5 according to ISO8501-1 or GB8923. Concrete should be firm, dense, flat, clean and dry, with loose sand, shelling, cracks, honeycombs or pitted areas repaired first. Wood should be clean, dry and free of burrs and loose fragments.

How should BW6-9526 be handled after opening?

The sheet advises stirring the coating uniformly before use, pouring out only the amount needed, sealing the bucket promptly, and not returning poured-out material to the original bucket to reduce moisture exposure.

Can thinner be added to BW6-9526 on site?

The data sheet says the viscosity is adjusted before shipment and thinner should not be added randomly. If temperature or site conditions require viscosity adjustment, the supplier should be consulted and a dedicated thinner used only after guidance is confirmed.
