Tanking Suggestions

Hi all, I am after a tanking "paint" for a shower enclosure.

Preferably from B&Q (sorry) as otherwise it will involve a massive round trip because of where I live.

Any suggestions?

Got my tanking stuff to paint on.

I have removed the old tiles from the 3 walls and am in the process of removing the leftover adhesive that is on the ply behind. Lots of it.

My question is, how much of this do i need to get off before tanking and tiling? Its proving fairly tough to remove and its never going to be perfect but im chiselling of as much as I can.

Can i tank over the little bits that are left and then even out the imperfections with the new adhesive?

I dont want to reboard as its only a 760mm tray as it is and also the existing boards form part of the actual wall when the house was built.

A Ply wet/enclosure wall is not the best background for tile or tanking liquid.

Ply boarding has rarely been been a new build practice for interiors. Is the ply fixed to studding or to a masonry wall?

Mould will have often formed behind ply on wet walls. The bottom right corner of the pic shows a dark area that could be water damage?

If you replace the ply you will not be losing any dimensions?

As a professional, i wouldn't attempt to tank the surface in the pic but it might work out fine for you as the householder.

Running a grinder over the adhesive will shift it - but dont go wild. And make sure that the ply has no flex, and is well screwed in.

Thanks for your reply.

The mouldy bits are on top of the adhesive leaving what looks to me like sound ply once chipped off.

As far as im aware i am removing the original tiling from a shower cubicle that has always been there.. Stud walls. House is about 15 years old.

I was just going to apply tanking liquid as an extra layer of protection. Do you think id be better off just tiling straight on and skipping the tanking then?

No, use the tanking now that you have it - it wont do any harm.

Ok thanks.

The ply is recessed rather than say surface mounted on to plasterboard......as if the walls were built that way knowing its for a shower. It seems sound enough but im struggling to get the adhesive off completely.

Can i tile directly on the tanking once dry?

I suppose my main concern was that the walls wont be entirely straight due to rogue bits of leftover adhesive but im hoping the new adhesive should even it out.

Yes, you can tile direct onto the tanking.

What size tile do you intend to use?

 

[nitro23456]

300x300mm

use a 6mm x 6mm notched trowel, and use it at a more like ninety degrees than the usual forty five degree angle - this will give you a fuller adhesive bed and room to play.
