Bath/Shower Wall Lining Question

[mic-d]

Thanks Mic, will do.

I have cut the villaboard back 10mm or so, that was fun...

There is now a sort of little cavity say 7mm under and behind the villaboard. I set the horizontal noggins at about 120mm above the base of the spa line, don't ask me why. One problem that this may cause though is that I will be unable to adhere the Sikaflex to anything behind, if you know what I mean. I will have to carefully fill the space so that the sikaflex sits in the curve of the lip up to the base of the villaboard, but with nothing behind it.

Do you think that is a problem waiting to happen? I thought about taking about 330mm of the villaboard (up to the next noggin up the wall) and then putting some noggins in right down at the lip, then replacing the board and w/ping the cut line. Do you think that is a good move or think it is ok just to leave it. I guess if the Sikaflex adheres well to the spa lip and the villaboard it would be ok?, not sure though as I don't know what the holding and flexi capabilities of Sikaflex are though.

Any thoughts you could offer would be great, then with a bit of luck I think it will be plane sailing from there.

Yep. Plaaane sailing, I'm sure.

Cheers James

Hmmm, nothing behind it? doesn't the spa lip have a vertical section that the villaboard laps over? Either just cut the nozzle quite wide to give a big bead of sikaflex and/or you can buy foam packing rods from places like bunnies to fill cavities like that, then sikaflex. Its not for aesthetics so fill er up. You will have a second bite of the cherry when you tile, leave a gap between the bottom tile and the spa and silicone it, don't grout it.

cheers

Will take your advice and pack the hole up. There is a vertical lip on the spa, just wasn't sure if that alone and the villaboard, which is about 10mm out from it would have been enough. I guess the packing will be good insurance. The wall cavity is still exposed under the spa so I can shove stuff up there to pack it out. Like you said, no asthetics required back there, which is probably a good thing!!

Many thanks for your help
