    I came across a guy using this stuff today on a ply lined bath area ,it looks a simple product with a strong adhesive strip that sticks to the back of a shower,bath sink and is tiled over the protruding 75mm ,Im just wondering what you lads make of it .

    Its very common on sites over here, getting more common in domestic applications as well. Its better in my opinion than plumber applied silicone that wont stick to the dusty wall. However most of them have them too tight around the corners and i have to cut the seal (thus rendering it useless & i fill it with silicone instead) to get a tile to fit right in. So as Dave says if fitted correctly they seem fine.

    Better just tanking the whole thing in my opinion though.

    Your right there Davy,plenty of it here indeed and too tight in the corners,
    i always cut it too when needed and silicon the gap to wall and even stick the seal tight to wall,the tanking kits tape has to drop into corner too,awkward when the seal is cut,lol.good old silicon(mapesil)

    Spoke with the plumbing ctr on the job and he said they install it with all their fittings now,something to do with leaks :yes:,I mentioned tanking to the main ctr and he visibly flinched..went upstairs and the tiler (yo-yo) was working in a shower area with classi-seal on 1 of the plasterboard walls :yikes:.

    The classi products are the best waterproofing products on the market in my opinion. I recently renovated my bathroom with the help of a friend who is a plumber/bathroom fitter. He recommended using a Classi Bathroom Waterproofing Kit for fitting a bath with an overhead shower and it was great. Really straightforward to install with clear instructions and my bathroom has been 100% waterproof since I fitted it! Think they even have a kit for wateproofing a wetroom
    Great products in my opinion.

    If I was a bit more cynical I'd say that post is just spam advertising, once @Dan@Dan has had a chance to see it he may agree...

    @C McC@C McC I will give you the benefit of the doubt on this occasion. I've removed all of the very well placed hyperlinks. Any further advertising like this and it's the ban button I'm afraid! Nice to hear you like classi seal though :rolleyes:

    They can stay with the plumbers in my opinion.

    No way you can get as tight a corner with classi-seal as you can using Kerdi-keba and and bonding it to the tray with Kerdi-fix.

    I agree @impish@impish . For me it can stay in the DIY sheds with the weekend warriors. No place in a professional installation..... IMO

    I have used this a few times on shower trays after being recommended on here from guys who create excellent work and I respect very much and by no means weekend warriors and it hasn’t been thick, obtrusive away from wall at the corner or any other negative it’s useless even tho I’ve never used it throw away comments! Kerdi is not the only solution for total waterproof guaranteed installation, there are lots and always comes down to the installers experience and confidence to install correctly. It is a very good option if used and installed correctly like any good product!

    I insist on them on large new build housing sites in conjunction with tanking.
    If the shower tray/bath are of good quality and square vertically i.e: the upstand and top are 90 degrees rather than sloped from a cross section point of view then the Classi seal installed correctly is no obstruction at all, it's only about 1-1.5mm thick.
    If when installing it the plumbers silicone it to the wall and have it nipped around the corner of the tray properly and not stretched it, then held the corner in place with a piece of wood scrwed to the wall until the silicone sets, when we come to tank it it's not in the way what so ever, it's a clean 90 degree and vertical internal angle.
    I do agree that there are other options out there but I haven't found any that are more cost effective when tanking large volumes of new houses with a restrictive cost to build.
