Impregnating Wood Preservative

SpecWood®
WB Impregnating Preservative

SpecWood® WB Impregnating Preservative is a one-component, water-based, solvent-free impregnating primer containing lignin-reactive components. Designed for bare natural softwoods and hardwoods, it penetrates the timber to help protect lignin from degradation while enhancing the water resistance, surface hardness, weathering resistance and durability of the complete coating system.

Pack size: 1L, 5L & 20L.

Features & Benefits

  • Deep penetrating
    Impregnates bare timber to provide protection within the wood rather than simply forming a surface coating.
  • Helps protect lignin
    Lignin-reactive components are designed to chemically prevent the natural degradation of lignin within the timber.
  • Extends timber and coating life
    Helps improve the long-term durability of both the wood and the subsequent coating system.
  • Enhanced water resistance
    Improves the natural water resistance of the timber.
  • Improved weathering resistance
    Enhances the weathering performance of the complete coating system.
  • Improved fade resistance
    Helps protect the timber and coating system against colour degradation.
  • Enhanced rot resistance
    Supports the natural rot-resistant properties associated with lignin in timber.
  • Improved surface hardness
    Enhances the surface hardness of the complete coating system.
  • Enhanced elasticity
    Helps improve the elasticity of the complete wood coating system.
  • High blocking resistance
    Helps reduce sticking between coated surfaces.
  • Easy application
    A single-component product suitable for roller or spray application.
  • Water-based and solvent-free
    Provides a water-based approach to impregnating and protecting natural timber.

Intended Uses

SpecWood WB Impregnating Preservative is intended for use as an impregnating primer on natural softwoods and hardwoods before the application of a suitable wood coating system.

The product's primary function is to penetrate bare timber and help prevent degradation of lignin. Lignin is an important natural component of wood that contributes to the rigidity and rot resistance of the timber. Protecting it helps improve the service life and performance of both the wood and the coating system applied over it.

Because the product relies on impregnation, it must be applied directly to bare, absorbent wood. It should not be applied over sealed or previously coated surfaces that prevent penetration.

Typical Applications:

  • Exterior timber decking
  • Natural hardwood surfaces
  • Natural softwood surfaces
  • Exterior timber components
  • Timber doors and frames
  • Outdoor woodwork
  • Exterior architectural timber
  • Timber screens and decorative structures
  • Wooden balustrades and railings
  • Outdoor furniture
  • Timber structures requiring subsequent protective coatings
  • Bare timber exposed to weathering and moisture
  • New timber requiring an impregnating primer before finishing
