The time has come round again to treat the wooden decking on the outside of my log cabin/shed.

It's literally a half hour job, so no big deal once every couple of years, but the problem is, when the surrounding lawn is cut bits of grass fly up and get lodged into the grooves, and after time they are difficult to clear out, even with a stiff brush.

I thought about boarding over with exterior grade Plywood sheeting (cut to size) all the way round and staining over, however, being wood it is susceptible to the elements, so I was thinking there may be some 100% waterproof sheets that can easily cut, maybe around 10/15mm thick.

I have found an odd offcut of Plywood, so you get the idea,

Give your deck a blast with a leaf blower after you cut the grass,

I could do, but it's a faff, the shed is right at the end of a fairly long garden.

If the surface was flat it would easily brush off,

I think over boarding with anything is a bad idea tbh, it’s just going to trap moisture under it and rot the decking.

There are schools of thought that believe that your decking has been installed upside down.

The thinking is that with groves down the water drips off the bottom easier and the planks are less prone to rot.

I have heard that at least one manufacturer has solved this conundrum by manufacturing decking planks with groves on both sides.

Buy a weeding broom
Stiff Wire Outdoor Weeding Broom, (W)140mm https://share.google/QRPI539PnJhWNdIBi

It will get in all of the grooves and should be ok if you use it lightly enough.

I take onboard what you are saying, but I will wait for a really hot dry day before fixing it down, and put plenty of treatment on the decking top first.

Around here, anything smooth like ply or hardboard could be very slippery at times.
That's why it has grooves, so you know which way you'll skid!

You could use GRP, or ceramic tiles perhaps?

I've seen some sort of bonded gravel/pebbles used on a balcony, which appeared to work quite well.

'Synthetic wood' decking maybe?

I'm not a fan of decking, I've seen far too much rotten wood.
But it's one of those things that people accept and don't look at, if you have anything different people will notice it.
So you have to try harder for it to look 'nice'.
