Description
Precision Gap-Adjustable Scraper Coater for XPS | Anti-Skid & Stucco-Ready Coating with Low Waste
This material-saving XPS board knife coater applies a precisely controlled wet coating layer onto extruded polystyrene (XPS) rigid foam boards. Unlike spray or roller coating, the knife-over-roll method achieves >95% transfer efficiency and eliminates overspray, which is especially critical for XPS (solvent-sensitive substrate). Excess high-viscosity coating (plaster, polymer mortar, latex, acrylic, or cementitious base) is recirculated back to the supply tank. Customizable blade gap, coating width, material viscosity, and surface adhesion promotion available for different XPS densities (25-50 kg/m³) and final applications (stucco-render ready, anti-skid walkable surface, fire-retardant layer).
Technical Parameters
Parameter Value / Range
XPS board width range 600 mm - 1250 mm (customizable up to 2400 mm)
XPS board length range 800 mm - 3000 mm (customizable)
XPS board thickness range 10 mm - 120 mm
XPS density range 25 - 50 kg/m³ (customizable nip pressure for soft boards)
Coating speed 2 - 30 m/min (adjustable)
Wet film thickness 0.3 mm - 5.0 mm (accuracy ±0.05 mm)
Coating uniformity ±3% across full width
Material transfer efficiency 95% - 98%
Material saving vs. spray/roller 35% - 45% (typical)
Blade type Round-edge or straight bevel (customizable hardness)
Backing roller material Silicone (soft foam) or EPDM (hard foam)
Coating viscosity range 2000 - 25000 cP (customizable pump)
Max drying/curing temperature 60°C (temp-limited to protect XPS)
Drying method IR + low-temp air (≤55°C) or ambient curing
Power supply 380V / 50Hz / 3-phase (or customer-specified)
Applications
  • XPS insulation board stucco-ready coating (for exterior facade systems - EIFS)
  • Anti-skid walkable surface coating (roof insulation, parking decks)
  • Fire-retardant intumescent layer (for building code compliance)
  • Adhesion promoter primer (for cementitious renders and tile adhesives)
  • Moisture barrier & UV protection coating (for temporary or exposed storage)
  • Color coating for XPS decorative panels (faux wood, stone pattern base)
  • Polymer-modified waterproofing layer (below-grade insulation)
Customization Options
  • Blade type & gap control - manual micrometer, servo-driven, or pneumatic (for soft XPS boards, gap floats over thickness variations)
  • Surface pre-treatment module - flame, corona, or plasma to improve coating adhesion (critical for XPS)
  • Single-side vs. double-side coating - inline flip station
  • Coating width - from 600 mm to 2400 mm (custom blade)
  • Backing roller hardness - softer roller for low-density XPS to prevent crushing
  • Recovery system design - continuous recirculation with screen filter (for sand-filled plasters)
  • Drying profile - low-temp IR + ambient zoning (no foam deformation)
  • Edge masking - for leaving dry adhesive edge for thermal break
  • Coating material type - cementitious, polymer, gypsum, acrylic, epoxy, PU
  • Automation level - from manual feed to fully automated XPS stack-to-stack line
Key Features
  • ✅ Up to 45% material saving vs. spray or roller - no overspray, scraped excess recirculated
  • ✅ Gentle on XPS surface - no roller crushing or solvent attack
  • ✅ Precise thickness control - ideal for stucco-ready base layer (min sanding required)
  • ✅ Handles sand-filled & fiber-reinforced coatings - carbide blade + wide-gap pump
  • ✅ No atomization - zero VOC mist, cleaner working environment
  • ✅ Quick blade change - <5 minutes for different coating profiles
  • ✅ Suitable for warped or slightly uneven XPS boards - floating blade design
  • ✅ Low drying cost - thin, controlled layer cures faster than thick spray coats
  • ✅ Compatible with water-based, cement-based, and 100% solids coatings
Support and Services
  • Free material saving & adhesion test - send XPS samples + your coating; we measure transfer efficiency and pull-off adhesion
  • Surface pre-treatment recommendation - flame/corona parameters for your XPS density
  • On-site installation & commissioning by foam-line specialists
  • Operator training (gap setting, blade selection, cleaning thick coatings)
  • Process optimization - recipe for your specific plaster/polymer viscosity
  • 24/7 remote support (video call + PLC access)
  • Spare parts kit (blades, seals, pump liners) included
  • Annual maintenance & blade sharpening service available
Packing and Shipping

Standard packing: Stretch-wrapped with anti-rust, wooden crates for control cabinet and drying tunnel

Shipping: FOB or CIF (40HQ container for standard line; longer tunnel requires split shipment)

Lead time: 40-55 days for standard models, 65-85 days for fully customized systems

Documents included: Operation manual, electrical diagram, CE declaration, spare parts list, XPS coating guide

Port of shipment: Shanghai / Ningbo / Qingdao (customizable)

Frequently Asked Questions
Q1: How much material can I save compared to spraying plaster onto XPS?
A: Typically 35-45% for medium-viscosity plasters. Spraying wastes 30-50% as overspray + bounce-back from rigid foam. Knife coating recirculates >95% of excess. We provide a customizable free test with your XPS and coating before order.
Q2: Will the knife coater crush or deform soft XPS boards (e.g., 25 kg/m³)?
A: No. The backing roller is customizable (soft silicone) and the blade gap can be set to a floating mode. Nip pressure is adjustable. For very soft boards, we add a rigid backplate support.
Q3: My coating contains sand or short fibers. Can the machine handle that?
A: Yes. We use a customizable carbide blade (wear-resistant) and an open-gear or screw pump (not a close-tolerance gear pump). Filters are coarser or removable. Recovery trough has a screen to separate large particles before recirculation.
