Factory-applied coatings are the most reliable way to protect and finish external timber cladding. By applying coatings in controlled conditions, we achieve consistent coverage, correct curing, and predictable long-term performance that is difficult to replicate on site.
Factory coatings – quick overview
Applying coatings in a factory environment allows precise control over preparation, coating thickness, drying conditions and quality checks. This leads to a more durable finish, reduced early weathering and a cleaner, more consistent appearance from day one.
​
Factory coatings can be selected to suit the timber species, exposure conditions and desired appearance. Options range from natural, breathable finishes to pigmented stains designed to manage UV exposure and colour change.

Most external timber cladding species benefit from factory-applied coatings. The coating system should be selected in line with the timber’s natural properties and the project’s exposure conditions.
Where projects require fire-rated timber cladding, coating selection must be coordinated with the fire-retardant treatment system. Coatings are chosen to remain compatible with the treated timber and the required reaction-to-fire performance.
For fire-related specifications, see: fire-retardant timber treatment and our fire-rated cladding product range.

Even the best coating system depends on correct cladding detailing. Ventilated cavities, drainage paths, fixing selection and junction detailing all influence how long a coating will perform as intended.
For guidance on build-ups and junctions, see our cladding detail design service.
To specify factory coatings, send your timber species, cladding profile, total m², exposure conditions and preferred appearance. We’ll advise a coating system that aligns with durability, maintenance expectations and any fire-rating requirements.
In most cases, yes. Factory application provides controlled conditions, consistent coverage and correct curing, which are difficult to guarantee on site.
Yes. Factory coatings extend performance and improve consistency, but all external timber finishes will require maintenance over time depending on exposure.
Yes, provided the coating system is compatible with the fire-retardant treatment. This must be specified as a coordinated system rather than as separate products.
