Features & Benefits

  • Rapid drying
    Touch dry in approximately 10 minutes at 25°C for faster production cycles.
  • Faster sanding
    Can typically be sanded after approximately 40 minutes at 25°C.
  • Excellent anti-blocking properties
    Reduces adhesion between coated surfaces, helping painted components to be stacked sooner.
  • Fast stacking
    Painted components are stackable after approximately 1.5 hours at 25°C, minimising production downtime.
  • Excellent pore filling
    Helps conceal minor surface imperfections and create a smoother substrate.
  • Low fibre grain lifting
    Helps maintain a smoother wood surface during the coating process.
  • Excellent flow and wetting
    Promotes consistent coverage and a uniform sprayed finish.
  • Excellent adhesion
    Provides a reliable foundation for subsequent coating layers.
  • Good durability and repairability
    Supports durable coating systems while allowing practical maintenance and repair.
  • Good stain and heat resistance
    Suitable for demanding interior wood and furniture applications.
  • Household chemical resistance

Intended Uses

SpecWood® WB Spray Filler Primer – RAPID is intended for use on wood-type surfaces, including MDF, where rapid processing and high filling characteristics are required.

It seals and primes the substrate to help protect against moisture and mechanical damage while filling minor surface imperfections. Its combination of rapid drying, excellent sanding and anti-blocking characteristics makes it particularly suited to high-production environments where painted components need to be sanded, overcoated and stacked with minimal downtime.
