Levelling for washing machine

Morning folks,

I have a small area under some stairs which originally had an old brick floor (750x2240mm). The bricks were totally uneven, so I have used self levelling compound and the floor is now pretty much level. I want to put a washing machine under the stairs though, so need something to go over the top of the compound. I was thinking about just cutting a sheet of OSB to fit. But not sure if that's the best solution? It's purely a functional area - the main objective here is just to get a level surface to stop the washing machine shaking.

Any thoughts much appreciated!

Washing machines have adjustable legs to level the machine so i'm not sure anything other than adjusting the legs will be needed.

Thanks for getting back to me.
The original floor was too uneven for the washing machine legs to compensate floor, so I think the levelling compound was unavoidable.
But now the levelling compound is down, I'm aware I can't put the washing machine straight on top of it. So would OSB work, or is there a better answer?
Cheers

Why not? If it is level enough now so that you can level the legs, what's the problem? I guess I don't see how adding anything else helps.

Maybe so. I guess I'm just worried whether a thin layer of SLC could take the weight and movement of the washing machine concentrated through the four feet.

Probably depends on how clean the surface was more than anything. If the concrete SL is bonded well it should be fine. You could glue a sheet of vinyl over it if you want it to look nicer and be easier to clean.

Did you use a self leveling primer before floating the bricks? This would promote a good bond with the surface below. SLC is not designed to be the wear surface and is only supposed to be an intermediary surface to help bond something like tile.

Thanks for replying.

I just used a 4/1 pva solution as that is what the SLC instructions suggested. I'm realising this might not have been the best option now I'm reading around a bit :/

Yea, I don't think there's any way the SLC could work as a durable surface.
