Love this system, some people have commented that it’s expensive, to me it appears great value for money.....there is a difference! Thanks Roger 👍

I use these kits on every install now, never had an issue.

As usual a very well explained video.Excellent approach

Amazing video and very good information as always 😊👌will use this before tiling 👍

In Detroit area "upstands" are on all shower trays and mounted to the studs before installing wall boards maybe there's a void but they don't leak usually leaks are at the strainer connection due to lack of mortar base below the tray or crummy connection skills

Getting some tomorrow. Thanks.

I fill between the edge of the tray and wall with silicon whist fitting the tray, after set I then run a bead around the top corner prior to tiling. Then use a water resistant tile adhesive. Haven't had one leak yet.

Abacus needs to post on her and on the skill builder channel, to be transparent and make people aware they need to make sure this is cool and not warm. As a lot of the reviews for this are saying taking the backing board off is an arse. They must of been aware of this so we never see Roger ever have issues.

I recently installed a shower tray and enclosure and experienced leaks, i had actually tiled the walls down to the floor and this was one of the reasons why i wasn't getting a good seal and after repeated re sealing with silicone sealant i went onto the internet to find a solution, i came across the "No more leaks" product and this is by far the best product i have ever sourced to cure a leak problem, i decided to apply low modular silicone around the edge of the tray and when cured i then installed the no more leaks seal, i then installed UPVC trim around the shower tray fixing with clear silicone and once all cured i sealed around the trim, the shower tray is now successfully sealed and i would like to thank Abacus for manufacturing a brilliant product and not to forget Roger bisby for such an excellent KZfaq installing demonstration and i would advice anyone to view the video before installing this product.

Been fitting shower trays for 20 years, always used bkack flashband, never had a call back ever.

hi another great tip . well done

If you're fitting wall tiles less than 10mm thick, then this product just isn't worth bothering with. First you'll have to trim a few mm off, otherwise you'll see it poking out underneath your wall tiles. Doing this but keeping a consistent depth along the full 2metre length is near impossible. If you managed to trim it, your next challenge is that most shower trays have a round / beveled top corner. This means that you're only going to get 1-2 mm overlapping the shower tray. When you consider the adhesive on this isn't sticky or thick, I don't see this adding any substantive extra sealing capability over good quality low modulus silicone. If it were thicker, then maybe it would work, but that would push your tiles up too much. Next, factor in that the tape comes pre-creased just to increase installation difficulty. The backing tape separates from the adhesive where the product was folded rather than rolled for the packaging. Result of this exposure to air means some areas of the tape have zero stickiness remaining. This means if water does find its way behind your tiles, this weak spot will fill with water, which may then break the remaining bond and render the tape useless. Ultimately I decided the potential extra sealing capability offered wasn't worth the potential problems it introduces, so I'm going old school and using a good quality low modulus silicone between the tray and walls, and then between the bottom of the tiles and tray. Done properly having installed plumb, true and square waterproof backer board of some kind will not let you down, and save you purchasing a very expensive wallpaper seam roller

Very interesting video. Do you think this solution is better than using Cladseal upstands? It does seem to be simpler.

Can this be used over shower boards in place and then tile at the bottom

Is there any solution for where the floor tiles butt up to the shower tray, particularly where you step in and out? Or is the fact that it's not seeing running water, coupled with a good job of the grout/silicone sufficient?

I use something called a Classi-seal. Really easy to use.

I'll be straight up here I like to tile everything and then fit the tray I've never had a cracked tray yet,, and always got the waste spot on,, and siliconing the whole upstand against the walls has never failed for me,, I also fit baths in the same way,, tile first then bath goes in,,, I also ratchet strap the sub frame legs of the bath to the joists so it's really pulled in and down (filled with water) until its set,, just a few idea's,, that way you don't need leak seals,, water won't get through 50 mm of vertical seal,, the bath edge ❤️👍

Cant you use the wedi tape and corner pieces for this job ?

Has anyone used the Mapei tape system before tiling and lipped to the top of the bath ?

Will it work with a direct to stud shower acrylic wall?

I’ve installed No More Leaks 3 years ago and I checked under my shower today and I was disappointed to note that there appears to be leaks and water under the shower coming from the edges alongside where the no more leaks tape is. It is Fibo shower board on top and I’ve removed the silicon which even after 3 years was in poor condition so I’m replacing that. However, I thought the point of no more leaks is if the silicon failed then no more leaks would stop any water creeping past the sill. I’m gutted and wondering what I can now do other than replace the silicon but I now know that below the silicon there isn’t an effective water barrier

Can you use the same board on the floor and seal it the same

I removed caulking from shower floor because it was getting moldy but water started coming from where I removed caulking and some of it has a bad odor, I have waited like 2 days but those areas where the wall meets the floor are still humid, what can be the problem? Where would that water be coming from? Should I just re-caulk?

There waterproof boards all over the walls seem to be over done, do I need to cover the whole place with waterproof boards?

Hi Roger one other question please, how much of a gap between the wall and the tray can no more leaks bridge? Can it bridge 3 to 5 mm? or does the tray need to be tight right up against the wall. Thank Chris.

Hi Roger I have seen you use the Classi seal system in another video of yours, which one of the two systems do you prefer? Thanks.

Great but what if it’s already built !

Can this be attached to a recently skimmed wall

If it's a bath that I'm fitting, the rim is supported on a batten screwed & glued to the wall so vertical movement of the rim against the wall is virtually impossible. Then overfill the gap between the tray/bath & the wall with silicon (having first made sure the edge of the tray/bath is really clean & grease free) then run a plastic scraper or rubber grout float along the joint flat to the bath & angled against the wall such that the slight excess of silicon is smeared up the wall by 30-50mm to create a waterproof upstand. Then I fit a simple L profile bath seal trim, sadly the only decent ish on I can find these days is from Wickes (genesis used to do a really good one for under or over tiles) that is meant to go on after tiling but I put it on before to create a 2nd upstand & seal it to the tray/bath with silicon & clean any excess away with wonderwipes. Then tile with 3mm gap between the tile & the trim which I fill with GROUT. This gives a very effective seal with no silicon visible within the shower or bath area that can go mouldy. If the water gets past the flexible edge of the trim strip, it then has to get past the silicon that bonds the strip to the bath/tray AND then has to get past the silicon that seals the tray to the wall. So far, in about 20 years of fitting baths & showers, I've never heard of one of mine leaking, or going mouldy.

Bought this and hope it will provide an extra line of defence on top of cladseal and silicone. Be aware it’s really fiddly and takes patience to fit as it’s so tacky. The backing tape doesn’t want to come off cleanly and the blu-tac like material sticks to it and stretches, making it harder to fit.

UK need to catch up and use American and Canadian baths

How many packs did he go through to get the perfect video, it never goes on like that

what if you already build the bathroom , then you can not keep it

Used this tonight. From a usability point of view, it is terrible. What a pain in the arse getting the backing off! The EverBuild stuff is soooo much easier to use. You don't get the preformed corners with EverBuild though. Can't comment on performance though.

This is great, I'm doing a shower tray exactly the same way (abacus boards etc) however this tape doesn't go on anywhere near as easy as Roger makes it look. First off the adhesive itself sticks the the backing paper that well, you can't actually get the thing off, then when you do (I had to use a stanly knife to get it going) the paper keeps ripping and your left with small sections of paper that you have to then pick at (again with a stanly knife) to get going again, this happened at least 10 times. Then trying to get it to stay 10mm on the shower tray is another very, very difficult task. All in all, I felt sick doing this supposedly simple task. I might have received a faulty one, who knows, but I do know it didn't go anywhere near as easy as this vid makes it look.

Now worried about this. I wanted to get this stuff and trust Roger but so many people on this Abacus video are saying the backing doesn't come off as easy as shown. So how many times was this edited to make it look easy? We need transparency which I thought Roger was.

Which is best in your opinion, ‘Classi Seal’ or ‘No More Leaks’ 🤔

Thanks for the great video. Does the manufacturer still exist? I bought this kit, but think it's defective (the adhesive doesn't go right across the tape), but the manufacturer is not responding to emails.

Small chunks works better, very sticky stuff, hope it works.

The tape is certainly not as easy to apply as shown in this video and it is difficult to ensure you get the correct amount on the shower tray. I also found that some of the backing paper did not come of easy. For this I followed the advice of another poster and put the tape in the fridge for 10 mins and this solved the problem. I also had to take a Stanley blade and trim parts of the tape where it was slightly further out on the shower tray than it should have been. Once stuck the tape does feel very secure. I too wonder what will happen to the tape if the silicone sealant needs changing in a time to come. I suppose using a waterproof non mould sealant will hopefully mean this is a long way off. I know firms want to sell their products , hence the really easy to apply video. It would be a different story if we got 20 people with different DIY skills levels to apply it.

There is a simpler solution called common sense.Subfloor covered with proper ready to tile tileboard,tiled all over and sealed around,then shower tray installed,sealed and wall tiled around and finally seal between tiles and tray.20 years never been called back.One thing - best done by a single highly competent person

I have now requested a third pack from the supplier. The first two, the paper backing is stuck on solid and unable to remove. I'll return them to the supplier(who has offered me a refund) but will give the third pack a go and if faulty then request a refund. It looks great in principle but am yet to use it!

i fitted a similar tape around 15 yrs ago, it was blue, rubber and had a 2 inch portion of the tape as a black tacky adhesive. it went on the side of the bath and up behind the tiles. seen it at an ideal home exhibition and the chap who made it done adverts for it. i will be looking for it this time now i have a new house to bath seal shortly, just prefer the , not sitting on top of the bath method, rubber seems more appealing. cant recall the name, think it was a Ireland product. my bath never leaked and i could produce tidal waves.....

If you have ever tried to platt chewing gum you’ll have an idea what it’s like trying to put this on! Use the thicker fleece backed butyl tape.

Used classi seals as well as no more leaks, both give confidence however the problem still seems to be the ends. The silicon gives way eventually, water doesn’t seem to get down the back as these up stands do their job but water travels off the ends eventually. Wondered what you would recommend and what silicon. Thanks

Great video and looks good. How do you remove the silicone when it starts to go black in time without damaging the tape please?

Hi great video do you take the plasterboard off the wall and fit the waterproof board direct to the joists / beams. I have t come across this board yet so I don’t no how strong it is can I get a tiler to tile direct onto it

This stuff will not stick if there is any old silicone sealant in the area , the film on the back is hard to get off and too wide on the 10mm side so is hard to get right in the corner.

Really enjoy your vids , is there a seal i can put over the tiles as it meets the trays, as I've tried resiliconing twice but I've still got problems, many thanks for any advice.

Not for amateurs with shakey hands 😆. "Used" this product earlier today... not pretty but sealed well... hopefully.

All being well sealling before tiling. But lets see what you can do to stop an eventual leak when your bathroom is already tiled and you are fitted a shower tray into the corner.... Take our bathroom its tiled floor to ceiling so how do i seal the shower tray from leaking....

why don't they include a flange on the shower tray to prevent water leaking out, the tile can simply go over the flange it wont leak?

Do I need to tank waterproof plasterboard if I use no more leaks round the tray and then mount shower board over the plasterboard?

Has anyone ever tried the emergency roof repair thick grey liquid that contains fibres in the cracks? I have a whole tin of it. Bit messy but making tape it off first.

Do a proper job: three lines of defence. First the seal between the tray and the tiles - use a good sealant, the hack-out & replaced it when gaps appear or it ages. Second (if the first fails) a tape system like the one in the vid. Third (if the tape fails or a crack emerges somewhere) a complete waterproof sub-tray e.g. fiberglass/resin with a drain that will drip in a visible place if water ever reaches it. That’s a proper job.

Put a bead of silicone behind it. Put the tape over the top once it’s cured then lay the tile and place another bead of silicone. It’s triple

What product would you use when you have shower panels already installed with a gap at the bottom which is filled with silicon....which is failing.

Better still why not get a shower tray with an upstand???

Why not just silicon the to sides of the tray to the backer board and sink the first tile on silicon too and then give it a finish line of silicon? I've always done showers and baths like that. Never a leak.

So would you recommend tiling behind the shower screen rather that up to it?

If the shower tray moves downwards can’t the tape come off the shower tray Isn’t the classi seal type better

Good stuff, where can you buy it?.

Affiliate opportunity if there has ever been one for this guy, the wall should come onto the base with an upstand tray and checked into the wall. The tape is a butyl tape used in everyday waterproofing. Use a professional if you want a warranty.

What is the name of the blue coloured paint?

Silicon is holding water in

Silicone sealant on butyl adhesive (0:55) ?!!

Problem with the paper sticking = but the tape in a fridge or freezer for a few hours and then use

Silicon only suitable for stable gaps but bath tub or shower tray even if secured properly to the floor and the walls will move when loaded with weight of a person plus water, not forgetting hot water and high pressure shower heads will find the smallest of gaps for water to leak through. Silicon is overrated material used from sealing double glazing to wet areas but rarely lasts long.

I have to agree with luvit 756. Followed instructions nowhere near as easy to put on as video will show or what the instructions say so sticky did not wanna come off of paper very hard to get into position I finally have but not so sure it’s going to work. Very disappointed in the product at present I have the Tiler coming tomorrow he told me not to use it but said if I give you peace of mind. Just hope I’ve done the right thing otherwise you can be sure I’ll be slamming it on social media

I’ve bought this but have noticed my tiles are much thinner than the ones shown in this video. I’m worried either there won’t be enough of a lip to seal properly, or it will be visible when the tile is fitted, making caulking difficult. Any tips from those who have used this before? (I got the 4m kit for a bath, with x2 corner pieces. Tiles are only 5mm thick).

Cheaper ones on the market which do the same job for half the price

If you really need to use waterproof tile backing board, you need to improve your tiling & grouting skills first, waterproof backing is a good belt & braces approach but grout is the most important and first line of defence, if water gets past the grout, the job has technically failed.

Never had a callback on bathroom installs in 40yrs: Some tips below for the correct silicone sealant method. 1. Fix all items firmly and correctly. 2. Most Important! Use a recommended solvent cleaner on all areas to be sealed. 3. Always use the correct sealant for conditions, sanitary for sanitary... 4. Never apply sealant to/over dry/drying sealant, apply in one. 5. Allow 24hrs before use.

You said this was difficult to work with. You are not joking. It is almost impossible to make a good job of fitting

I'm not tempted by this product, it looks very fiddly, I wouldn't trust the self adhesive bond to the tray and it still means silicon on show in the shower area to go mouldy

I am super saver I use under 20 litre I don't gruise disgusting sewer connected water flash toilet 16 high. I use squat compost toilet no liquid icdod

Filling a bath with water before you tile 🤣🤣🤣🤣🤣 just finish the tiling then screw the feet down one or two more turns to push the bath up tight against the tiles.

Good old Gordon Ramsey

yes, BUT the adhesive tanking tape is EXTREMELY difficult to apply without making a pig's ear of the job. Looks so easy but it's not.!!

Why have you changed the product Abacus?? I swore by this product on my bathrooms but you've now made it less tacky so doesn't adhere to the shower tray as good. Won't be buying again!
