Outside · Exterior Wood & Cladding

Outdoor timber that weathers the years, not the seasons.

Vertical exterior wood under sun, rain and damp — facades, cladding, fascia, pergolas, doors and window frames, primed against blue-stain and topped to shed weather. Here is the system we specify for exterior wood and cladding.

  • Cladding
  • Fascia
  • Pergolas
  • Doors & windows

The recommended system.

The right primer for each finish, then one topcoat by the look — open-pore varnish to show the grain, or weatherproof paint and lacquer to cover it.

For exterior wood and cladding, this is the system we specify — the primer that matches your finish, then the topcoat that suits the look and the part. Prime first; then pick one finish.

02Finish · choose your look

Over the primer, pick one topcoat by the look you want — the grain showing through, or covered under a solid colour.

Just oiling a pergola or a fence? Terrace Wood Oil 236 is a penetrating exterior oil whose LEINOS applications cover pergolas and fences — a leaner, oiled alternative for those parts only. It is not specified for cladding, fascia, doors or window frames; for higher pigment and UV protection on those, LEINOS points back to Premium Wood Varnish 260.

03Painting it solid? Match the paint to the part

A different intent: for an opaque, solid-colour finish the right paint — and the right primer — depends on the component. Cladding and shutters keep the biocidal 150 base; windows and doors take Resin Lacquer Primer 810, the primer LEINOS specifies under the 840 lacquer. Pick the route that matches what you are coating, not both.

builds one open-pore varnish to show the grain and two opaque finishes to cover it — and specifies the matched primer under each: a biocidal impregnation (150) under the grain-show varnish and the cladding paint, and Resin Lacquer Primer 810 under the silk-gloss joinery lacquer. Outdoor timber that is not primed for its finish has no business carrying a topcoat. None of these exterior finishes uses a separate care product: you keep them by cleaning down and recoating with the same finish when the weather has had its years.

Why it’s demanding

What the weather puts an exterior finish through

  • Rain & movement

    Rain & movement

    Driving rain soaks the timber and the daily wet-dry swing makes it move — a brittle film cracks and lets water sit in the joints.

  • Sun & UV

    Sun & UV

    Relentless sun bleaches and greys unprotected wood — an exterior finish has to carry real UV resistance, not just colour.

  • Damp & fungi

    Damp & fungi

    Exterior timber is open to blue-stain fungi and rot — the system has to start with a primer that protects the wood, not just dress it.

The primer protects the wood. The topcoat protects the look.

On exterior timber the colour is the easy part — it is the unseen base coat that decides whether the wood is still sound in ten years. Prime against blue-stain and rot first, then choose the finish for the look you want. Skip the primer and the best topcoat in the world is just paint over a problem.

Questions about exterior wood & cladding

Quick answers on formulation, application and Indian-climate suitability. Pulled from our full FAQ and TDS library.

Yes — and the primer depends on the finish. The open-pore varnish 260 and the cladding paint 850 go over Impregnation Wood Primer 150, the base coat that penetrates the timber and carries film protection against fungal attack (blue stain); its TDS specifies one generous, undiluted coat. The silk-gloss joinery lacquer 840 is a different system, primed with Resin Lacquer Primer 810. Either way, the topcoat goes on once the primer has dried fully.
