Thread: need help with faded red cedar weatherboards

Oxalic acid (powder) will bring the colour partially back as long as the wood is free of oil. It works with internal timber and furniture. No promises on how well it will work on weather board and how long the colour change will last. Buy a small amount and test on a small area where it wont be too obvious if it doesnt go as planned. Wet the wood first and slap the powder on. Dont forget it's an acid!

You might want to try a little bleach on a spot that's not so obvious. I bleach our eastern red cedar pool deck every year. It seems to work well in eliminating the gray and brings back some of the color but not all of it. That's with locally grown eastern red cedar - not sure how it would work on cedar that's from across the pond so test if first...

Bleach also works great in killing black widow spiders that like to nest under the pool deck.

there's a few products at bunnings that help rejuvinate grey timber

thanks guys, il give all these ago, much appreciated

what about a high pressure clean...

Timber hasn't faded - it's what UV does to timber.
Major difference between internal paint / stain and internal is a UV protectant.
Yes, oxalic acid - or Woodclean, by Cabots.

Then recoat.
NB> The darker the stain - the UV preserver they can put in it SO clear oil hasn't little, if any, UV protectant.

Wood duck

I heard from a professional paint man - that just Base 2 exterior latex paint (with no pigment mixed in) is a great clear paint for outdoor stuff. He also said, it protects the wood against UV rays, color fading and provides mildew resistance. Furthermore he also said it looks all cloudy in the can but dries clear. I never tried it myself, so I can not say it's true or not but I thought I would pass the information along, hoping someone with paint experience would chime in with some facts.

Thanks
