CD50 Extreme is the timber protection of choice when it comes to the most extreme situations. From locations in harsh environments (coastal, high humidity, dampness), to building products that are pretty extreme themselves (logs, thick posts or beams). Because CD50 penetrates deep into timber, it can get in to protect the thickest of timbers. CD50 Extreme is specifically formulated for just these jobs.
If you want to minimise warping, cupping, checking and splitting, and help control mould and fungus - reach for CD50 Extreme. It will add years of life to your timber and means less time and money spent maintaining your timber.

Great product, best thing for wooden decks. No cracking or peeling, just was and declare, or let it silver off knowing that the timber is protected under the surface.

I found the product way better than other brands I've tried. Its easy to apply it doesn’t try and alter the colour, easy clean-up, and if it does what they say. It will protect my expensive deck and make it last much longer.
Worth the effort

Recommended by our timber hot tub provider and had brought the tub back to tidy and was easy to use.

This oil brought my sun-bleached decking up to a beautiful standard, l used a lot more than l thought l would have. 12 litres on a 2.6 x 24 mtr deck, however it was well soaked in and the rain did not penetrate it at all. The deck looks better than when it was first put down. I used a sheep skin deck mop and very pleased with the fantastic results.

Great product, the clear oil gives the redwood a perfect wet look that shows up more of the natural grains and colour.

I built my deck from Vitex 3 years ago but then finished it with with an acrylic decking “oil” which turned out be completely the wrong thing to do. The product didn’t wear well at all and within 6 months it looked terrible, so I decided to sand it back completely and start again. This time I did my research and went with CD50X. What a difference! Now the deck looks stunning and can stand moving furniture around without scrape marks and scratches, I am so pleased, should have done this in the first place.

Excellent product - great looking on Vitex and easy to apply. Water on the surface of the deck indicates excellent protection from water penetration.
