classi-seal

[gixer]

Quick question folks , i have already installed a shower tray using classi - seal only for it to leak a couple of months later
Should i reinstall tray with classi-seal taking more care this time to flatten out any small creases in the classi-seal as i feel this is what must have caused it to leak in thew first place , or should i not bother with the classi seal

Thanks in advance Gixer

Classi seal is meant to be put on without ripples.
It is good gear and i'v never seen many problems, mind you seen one last week where a tiler cut it low in the corner and used no silicon.
I always fill the back with silicon and a bead along the front too for safety.

Another point... how is the water getting through to the seal????
Have you no silicon along the base tiles?

Thanks for the tip hillhead with the silicone , when you look at the black tar like strip of the classi seal it isnt completly smooth , its as if the machine that produced it layed it on thicker in places . When you look at the backing paper it appears rippled , i presume when i first applied it i didnt press this home enough to eradicate the uneveness or press out any small air bubbles in it therefore giving water somewhere to get through .
I did have a bead of silicone along the bottom where the tile meets the shower tray

Thanks Gixer

Hi gixer, I don't like the sound of unevenness on the classi seal sticky part.
It is meant to be smooth so as to work effectively.
Don't be afraid to check that out, I will be fitting a marble tray today and a classi or similar seal going on it. I'll keep eyes peeled.
It does have to be smooth though.

Personally i'm not a great fan of classi seal or similar products, i find best way to install tray is to silicone to edges to the walls when 1st installed, then tank/tile etc. then final bead of silicone. you can tank walls 1st then silicone tray in then tile and then finish bead of silicone...


good luck but I would ditch the classi seal if it is rippled..

we had a thread recently about the classi seals, i think they're only good if the walls are bang on 90 degrees. any variation and the seal protrudes past the back of the tile

Many thanks folks for the informative replies , unfortunately i have refitted the classi seal , taking more care this time to get a better seal to the shower tray with the classi seal , and applied silcone front and back . Fingers crossed this time no leaks . When reinstalling shower posts to wall am i right in thinking i should apply silicone at least to the bottom of these to help eradicate any further problems with leaking ??

thanks again Gixer

Shower posts need siliconed too, then silicon around the outside of curve or 90 degree.
