Mass Timber Protection — CUTEK EURO
Description

CUTEK EURO is a high-performance, oil-based penetrating wood stabiliser manufactured in New Zealand for exterior and interior architectural applications. Formulated to protect from the inside out, the single-component oil diffuses deeply into laminated timber substrates such as GLULAM, CLT and LVL, to repel moisture, control liquid and gas phase moisture movement, and improve dimensional stability.

Unlike traditional film-forming varnish or natural oil coatings that crack, flake, or peel over time, CUTEK EURO features a permanently mobile, self-healing action that actively drives out water and migrates to seal cuts or fastener perforations. CUTEK EURO is an effective moisture management system for mass timber builds, whilst providing a final aesthetic finish. 

CUTEK Euro is the copper-free alternative to the signature CUTEK Extreme CD50, developed specifically for light colour timbers, such as Radiata Pine. 

Key Features
  • Deep Penetration Technology: CUTEK diffuses into the timber substrates to provide an effective moisture management system to protect timber during construction.
  • UV-Resistant Colourtones: Transparent CUTEK Colourtones showcase natural wood markings and knots without obscuring the grain, delivering extra UV stabilisation and achieving the desired design aesthetic.
  • Permanently Mobile Self-Healing Action: Stays active inside the timber to protect from the inside out, automatically migrating to seal subsequent cuts, drill holes, or fastener locations.
  • No Flaking, Cracking, or Peeling: Colour is designed to gradually fade over time with weather exposure, avoiding the risk of film degradation and eliminating the need for costly sand-and-strip rectification.
  • High Spreading Rates: Offers cost-effective application with up to twice the coverage rate of standard wood coatings, providing a spreading rate of 10-15sqm/L on Radiata Pine laminated timber substrates. 
  • Accumulative Maintenance Protection: Builds long-term internal protection over successive applications, meaning subsequent maintenance coats typically consume less oil and extend the intervals between recoating.
  • Factory Coat: Timber can be coated in factory and then again on site to fit with project moisture management plan. 
Scope of Use
  • Sutiable for laminated timber substrates such as GLULAM, CLT and LVL
  • Provides effective moisture management and aesthetic finish
Limitations on Use
  • Ground and Water Immersion Restriction: Must not be used on surfaces in direct contact with the ground or designed for permanent water immersion.
  • Moisture Content Cap: Cladding timber must be dry with a maximum moisture content of 17% prior to coating; higher moisture levels significantly delay penetration, causing the oil to remain tacky on the surface.
  • Pre-existing Surface Barriers: Cannot be applied directly over active film-forming surface coatings (such as standard paints, acrylic stains, polyurethanes, or varnishes); previous coatings must be removed completely with mechanical abrasion or a suitable stripper prior to application.
  • Environmental Exposure/Application Temperature: Requires 2–3 days of dry conditions post-application to facilitate proper oil diffusion. Application in cold weather thickens the oil and may lead to over-application; warming the oil in a sunny or warm area is necessary to enhance initial thinning and penetration.
In-Service History

Notable projects include Air New Zealand Hanger, Fisher and Paykel Head Office, and Melbourne West Gate Tunnel.
