FAQ

Does Thermowood cladding need treating?
No further treatment is needed. To keep the original colour for longer, you can use a UV oil such as Treatex UV Oil.

What should I use on oak cladding?
Treatex External Virgin Oak Oil, with Treatex UV Oil applied as a top coat if you want extra UV protection.

Do I need to treat cut ends on treated softwood cladding?
Yes. Re-seal any cut ends with an end grain preservative, such as Owatrol PCD 91 End Grain Protection for pressure treated wood.

Do factory-painted boards need a finish?
No. Our painted featheredge is supplied factory painted, and no further finish is needed.

Can I use UV Oil on decking?

How much treatment do I need?
It depends on the timber and how you apply it. Where the maker states coverage, it is on each product listing; otherwise ask our sales team.
