Bit Of Advice

[MartynT]

just wondering if anyone could give me some advice, I'm re doing my bathroom and come up with the idea of fitting the basin into a countertop above the ceiling for the stairs as its dead space, I know it's not ideal but i had some p5 chipboard lying around so I decided to use that for the countertop, I want to fix this down and tile onto it, as I say i know it's not ideal but if it's tiled, sealed well and only gets the odd splash of water now and again should it be ok?

it swells up and breaks down pretty easily, maybe tanking it would be a good idea

I would overboard it with 6mm Hardiebacker if I were you, it won't add much to the height. Chipboard is next to useless when wet.

or overboard it with hardie

Ok cheers, how do I fix the board down just screw it?

hardie will just transfer water through. Use Wedi board or Kerdi board at 6mm. Far far easier to use and fix too.

Hardiebacker - PAH!

Easier to use yeah, not easier to get hold of, though!

Could just tank the Hardiebacker.

May as well use hardboard as an overlay in that case!

This seems a lot of work for something that won't be constantly getting hit by a lot of water, it will at most get a few splashes that would be wiped up pretty much straight away surly the tiles and grout would hold it off till it gets wiped up?

You really don't like Hardiebacker do you

Nope! It has some use as a floor overlay but has zero place anywhere else.
It's heavy, water sensitive, dangerous with its dust, difficult to cut and fix... You get the picture.

I do agree with some of those things, but Kerdi/wedi on that is probably a bit ott given its cost.

I'd simply rough it up with sand paper and tile it with tilemaster ultimate. For domestic use, it'll be fine.
