cwr Posted July 24, 2021 Share Posted July 24, 2021 Just got some decking planks to make steps for the static caravan. There's course grooves on one side, fine protruding ridges on the other. Wondering which way up to put them? Don't care about asthetics, just concerned about grip, esp in damp winter conditions. Thanks Link to comment Share on other sites More sharing options...
Onoff Posted July 24, 2021 Share Posted July 24, 2021 Grooves down. They're there to aid air flow underneath and help prevent rot. It'll still be slippery. Paint with anti slip deck paint like this. It really works: https://www.toolstation.com/cuprinol-anti-slip-decking-stain-25l/p22463? I've heard the No Nonsense stuff is equally as good. Just redo it periodically.

Bramco Posted July 24, 2021 Share Posted July 24, 2021 1 hour ago, Onoff said: It'll still be slippery Ours isn't but it's south facing and very well aired - it's a raised deck. So you might want to see how it goes before applying antislip. You can always pressure wash it if it does get slippy and apply it later.

Ferdinand Posted July 24, 2021 Share Posted July 24, 2021 Disagree with @Onoff. Decking is normally raised on a framework, so I don't see how grooves-down actually adds much. I do mine grooves up. Which matches your situaton. Maybe grooves down if you are installing it directly on eg concrete. Horses for courses. Anti-slip is a good call, but I wonder if those microbeads are plastic? Or do it with a more normal thing and sprinkle sharp sand on before it dries. 1 Link to comment Share on other sites More sharing options...

Tbh the ones to really comment are the board manufacturers themselves. Grooves in wooden decking, in my experience do little to aid grip anyway. They're just let's be honest troughs for moisture and debris to collect. @cwr check with the board supplier and let us know what they say. Link to comment Share on other sites More sharing options...
Mr Punter Posted July 24, 2021 Share Posted July 24, 2021 I have smooth Ipe hardwood decking on Iroko hardwood joists. No slipping at all. I doubt they will rot any time soon. Link to comment Share on other sites More sharing options...

I read it was groves up . @Onoff knows (expletive deleted) all . It’s one of those miss understood things . Groves up ! Link to comment Share on other sites More sharing options...

SimonD Posted July 24, 2021 Share Posted July 24, 2021 There was an article on this in one of the nationals during lockdown telling everyone they'd laid their decking the wrong way up/wrong way down; it's as @Onoff says, grooves go down. 1 Link to comment Share on other sites More sharing options...

These ridges on the board may face up to provide functionality and aesthetics. Or they may be installed facing down, the orientation recommended by manufacturers as the correct way to install them.

Of course he wants you to have it the slippy @Onoff way up ! 1 Link to comment Share on other sites More sharing options...
