Sikkens Filter HLS Plus 5L 085 Teak

Sikkens Cetol HLS Plus in 085 Teak is a premium-quality, solvent-borne, exterior woodstain designed as both a standalone protective finish and a basecoat for other Sikkens systems such as Cetol Filter 7 Plus. This versatile wood treatment penetrates deeply into the wood surface, delivering rich, translucent colour and long-lasting protection from weathering, UV rays, and moisture.

Key Features

• Penetrating Woodstain Formula
  Soaks into timber for maximum adhesion and durability, protecting wood from the inside out.
• Rich Teak Colour (085)
  Enhances wood's natural character with a warm, golden-brown finish that accentuates the grain.
• Dual Functionality
  Acts as a basecoat for multi-coat systems or can be used on its own for less exposed areas.
• UV and Weather Resistant
  Contains translucent iron oxide pigments to provide superior protection against fading, cracking, and weather damage.
• Microporous & Water Repellent
  Allows wood to breathe while repelling rain and humidity, preventing warping or rotting.
