It is positioned for high viscosity and stable bonding across most wallpaper applications, 20kg bulk supply, and OEM packaging. This product is positioned for wallpaper glue brands, importers, distributors and contractor channels. Buyers can discuss viscosity feel, dispersion, application fit, 20kg bulk bags, OEM small packs, sample testing, batch documents and repeat-order planning for the target market.

Wallpaper glue powder dosage and coverage reference (1:25–1:30 water ratio)

  • 200 g: approx. 25–30 m², published factory reference.
  • 300 g: approx. 38–45 m², proportional estimate from the 200 g reference — confirm with a sample test.
  • 500 g: approx. 63–75 m², proportional estimate from the 200 g reference — confirm with a sample test.
  • 1 kg: approx. 125–150 m², proportional estimate from the 200 g reference — confirm with a sample test.
  • 20 kg: approx. 2,500–3,000 m², proportional estimate from the 200 g reference — confirm with a sample test.
  • Coverage depends on wallpaper type (paper-backed, non-woven, heavy vinyl), wall flatness and absorbency, water ratio and application method. Confirm with a sample test.

What "best wallpaper glue powder manufacturer" means for B2B buyers

  • Instead of relying on a "top 10" list, compare manufacturers on verifiable criteria: published viscosity with test conditions (our K6 is 38,000 ±10% mPa·s and 999 is 60,000 ±10% mPa·s, both measured at 5% solution, No. 4 rotor, 6 rpm), disclosed plant-starch material, and per-batch TDS/MSDS/COA transparency.
  • A factory wholesale supplier should also confirm OEM/private-label capability (200g–1kg packs under your brand), 20kg PE-lined kraft bulk supply, sample terms and export documents — all confirmed by quotation, never fixed promises.
