Why Does Teak Furniture Turn Grey? (And Why That's Not a Bad Thing)
If you've got teak furniture sitting on a patio, deck, or dock anywhere in the GTA or Muskoka, you've probably watched it happen. That warm, honey-brown finish it had when it was new slowly fades to a soft, silvery grey. It's one of the most common questions we get asked, so let's clear it up properly.
It's Not Damage — It's Oxidation
Teak turning grey is a completely natural process, not a sign that something's wrong. Teak is packed with natural oils that make it one of the most weather-resistant woods on earth — it's the same reason teak has been used on boat decks for centuries. When that wood is left outside, exposure to sun, rain, and air slowly oxidizes the surface layer, fading the honey tone to grey.
Here's the important part: this is purely cosmetic. It's happening on the very top layer of the wood. Underneath that greyed surface, the wood is still just as strong, dense, and structurally sound as the day it was made.
How Fast Does It Happen?
In our climate, teak left completely untreated typically starts showing noticeable greying within 6 to 12 months. Pieces that get more direct sun and rain exposure — think an unshaded patio set versus furniture tucked under a covered porch — will grey faster.
Do You Have to Do Anything About It?
Honestly, that depends on what you want. Some people genuinely like the silvery, driftwood look and choose to let it happen on purpose — there are even products designed to speed up that greying for people who want it. If that's your taste, there's nothing wrong with leaving it alone.
But if you'd rather have that original warm, golden look back, the good news is it's very achievable. Grey teak isn't ruined teak. A proper cleaning, light sanding, and brightening process removes that oxidized top layer and reveals the same rich, honey-toned wood that's been sitting right underneath the whole time.
What We See Most Often
Most of the calls we get aren't from furniture that's mildly grey — they're from furniture that's been neglected for a few years and has gone past grey into looking genuinely tired: dull, blotchy, sometimes with mildew or built-up grime on top of the natural oxidation. Even then, the wood underneath is almost always salvageable. Teak's durability is exactly why restoration works so well on it, even after years of neglect.
The Bottom Line
If your teak has turned grey, don't assume it's beyond saving or that you need to replace it. It's just doing what teak naturally does when it's left outside.
