Raw timber finish that adds the least amount of colour.

Hi.

This is for decking boards. The owner likes the way it has weathered - after being jet-washed, it's now a light fawn colour. They know it needs protecting, but would like the coating to be as finish-unchanging as possible.

What do folk suggest? Ta.

We've always used Barettine clear decking oil - works well and let's the natural colour show through.

Whatever you choose, try it on an inconspicuous sample area first. You don't want to treat half of the balcony(?) and then find that the householder doesn't like it!

Cheers, folks.

Not my job - I'm just trying to advise. The problem with test spots is the initial purchase cost of a tin.

Just wondering if there's anything less darkening than anything else. I'm guessing a translucent oil would be best for this aspect, but likely not for longevity.

I used Sadolin Extra Durable Clearcoat, and disappointingly it changed the colour of my shed a lot.

I've used this on a small fence and it doesn't change the colour in the slightest:

Have also used Cuprinol clear wood preserver which gives a slight golden tint to bare wood.

Thanks.

I have recommended a spray with an actual preserver like that first, and - yes - it is invisible when dry, but the subsequent coat to nourish and waterproof the timber will do the unwanted darkening.

Ooh, potential? Anyone got experience of this or similar?

Hmm, I'm thinking it might be like Thompson's Water Seal, so very smelly? Silicone repellent? It says it's ok for furniture, so presumably once dry there should be no issues with folk sitting on it?

I know it wouldn't 'nourish' the timber, tho'.

Semco.

Not cheap but keeps the natural colour of the wood.

They went for Ronseal Decking Protector in 'natural', as it was the best option at a local store. It left an unwanted golden hue, but it's acceptable.
