- Mapei UK's Shower Waterproofing Kit www.mapei.com/G....
Easy to use kit containing everything required to waterproof a shower in one tub. Contains: Mapegum WPS, Shower Waterproofing Kit Primer and Waterproofing tape.
Just used it and it worked great, easy. Thanks for the tutorial.
If you have thin latex gloves, recommend using them unless you want a free wax/exfoliation. Took hours to get it off my hands! =P
Left the protective cover down like the video said. Ended up pealing back the mapei tape when removing it after a few days.. should have removed the masking tape before the mapei had dried and retaped to protect tray while tiling
I applied the primer to the tile Backerboard a few months ago but got sidetracked with other projects. Will I have to prime walls again?
If so. Is the Mapei primer G the same as the primer included in the kit? Or can Sbr mixed with water be used? Thanks
In my jobs i waterproof hole bathroom floor and shower horizontal corner. In this case i would just tape use wps and silikone between wall and battom together then efter tile silikone again
I have used Mapei AquaDefence on walls on my bathroom where tiles are to be used as the walls of finished in dot and dab as an additional precaution including the wooden shower tray plinth I have built. Can I take it that the Shower Waterproofing Kit will be compatible with these?
Hi MaipeiUk. May I ask whether it is possible to paint (oil-base) over Mapeigum WPS? Thank you
So you return any water behind the tiles into the shower tray, but then in front of the tiles you have a silicone bead. Won’t this stop the water from returning to the tray.. it will just build up behind the tiles, no?
I was wondering this too. Wouldn't that first lowest level of tiles hold back a certain amount of water behind it.
If you're worrying about the silicone bead preventing water that has already leaked through the tiling/grouting flowing back to the tray, that's some serious leak you're talking about which would have caused serious damage to your house had the water proof barrier not been behind the tiles. The whole point of this system is to reduce liklihood of water damaging the rest of your house. Too many showers rely on the silicone only as a barrier, which isn't sufficient unless you resilicone every 5 years or so, and that absolutely requires the shower enclosure frame removing to do so properly. Most shower leaks occur under the enclosure frame where it sits against the tiled wall and tray, then people stupidly start siliconing the inside of the frame, which doesn't fix the issue and sets it up for a larger failure.
Is it ok to put this onto dry plasterboard (no skim) and then tile straight on?
Yes, tub says plaster or plasterboard
Thanks for the tutorial, I feel confident with handling this on my own
Lol I’m glad to see I did it the same way. I found this tutorial after the first coat😂
Is product suitable for microcement in shower?
thank u mapei for easy intructions
About to start a 1200 by 800 shower thanks for the tips and video
Hi. Can it be applied on a lime plaster wall instead of fixing backer boards to help with waterproofing?
A) once tanking has been applied and dried, do you need to apply tile primer on top of the tanking before tiling?
2) when tanking on top of plaster that is very porous, could you apply tile primer first, let the plaster suck all that in, then apply the tanking primer and membrane?
Hello, You do not need to prime the tanking system before tiling.
Had it applied last week in ensuite shower area. The smell is horrendous. Really toxic but it's meant be non toxic. We have tried having the fan on 24 hour in ensuite. Keep bedroom window open all the time to try to get the smell out (no window in ensuite). Extractor fan on. Burnt lovely candles, burnt incense.....
It's such a nasty smell. It's been put over WEDI boards.
I have tested it on an offcut of wedi board and the same pungent smell appears.
Having smelled the actual container it smells like amonia which apparently isn't normal.
Is this smell going to go away or do we need to remove our new panels, remove our new wedi boards and get a tradesman to come start all over?
Same here, I used the product to waterproof bath/shower enclosure and the smell is still extremely strong days afterwards despite room being aired 24/7 since being applied. Smells like burnt plastic. I really hope the smell is going to go away, starting to regret having used this product.
@@julielecomte1911 after a couple of months of trying to let the smell settle and the company taking away the product and testing for abnormalites (obvs found nothing so they didn't have to compensate).. .I had to rip the entire shower down dig up the wall etc to get rid of the smell and start the job completely from scratch. Worth it to have got rid of that product in my house 'never again'.
Very strange. Ours didn't smell while I was putting it on, I'll have to check in the morning again if something developed. We did it on to cement board. Wonder if yours was a bad batch 🤷♂️
@@redfox05nl The company claimed it was perfect!! Sent it to a lab 'apparently' they never proved that. Sent a Rep over who actually said to my face 'I can't smell it'...talk about gaslighting!
i have just had the bathroom replastered and it,s going to be covered with water down emulsion can this kit be used on the coated wall or is it better to use the primer on the clean plaster with out any emulsion
Hi Wayne, thanks for getting in touch. We would recommend that the walls are not painted before applying the tanking membrane and primed if required. Hope that helps you out.
where can I buy this in Portugal?
can it be used to water proof over existing tiles
Hi David, thanks for getting in touch. Yes it can be used over existing tiles but you must just clean the tiles and not use the primer. Then paint the Mapei Mapegum WPS directly on the tiles.
Are you saying you then tile over the tiles again? Surely the wps over the tiles won't waterproof the existing tiles and make them look nice, out would just be a wall of grey wps?
I have aqua panel boards instead of plywood or plasterboard, so should i apply the waterproofing all over?
Will it react or damage the aqua panel?
hi Myles, AquaPanel are only water resistant and it would be recommend to tank the entire surface before tiling.
I used hardiebacker board and that's similar to aqua panels. And applied the waterproofing kit all over that
Please could you explain the difference between Aquadefense and Mapegum products?
Further to your request please find a brief comparison below:
Mapegum WPS:
• Domestic use
• 24 hours drying time before tiling
• 0.5mm dry film thickness
• Internal only
AquaDefense:
• Domestic and commercial use
• 4 hours drying time before tiling.
• 0.8mm dry film thickness
• Internal & external (secondary layer of protection)
We hope that helps, should you require anything further please do not hesitate to contact us.
Can i put scimcoat over this?
Unfortunately no , the Mapei Shower Waterproofing Kit is to be installed directly below the tiles .
Is this suitable to use with microcement?
Unfortunately we would not recommend a microcement topping onto our Mapei Shower Waterproofing it. The system is flexible which can cause the microcement system to crack and fail.
can these rollers/brushes be cleaned with water and re-used again? .... for primer maybe yes, but for the Mapegum WPS too ?
or even just keep the roller / brush in a plastic bag until the next coat and then discard them ?
also I think it can be watered down for concrete and plaster ? otherwise only get about 3m2 coverage as it soaks up too quick in the plaster, and that's with one coat

You don’t get enough tape in the kit
Thanks for getting in touch. There is enough products in this kit to do 2 walls of a standard 900 x 900mm corner shower unit. Therefore 5m of tape will cover the two lengths of 900mm to the tray and 3m up the wall in the corner. We hope this helps.
@@MapeiUK For a shower enclosed on 3 sides (2 corners) I would say that is nowhere near enough tape so.
@@peterconnell2451 The Mapei Shower Waterproofing Kit is designed to tank a corner shower cubicle around 800x800mm. If you need further advice please call our technical department on 0121 508 6970 - Option 2. Thanks
@@MapeiUK As some have pointed out, there doesn’t seem to be enough product to cover larger showers. but I guess the product could be applied ground up, so in the event that the product isnt enough for larger showers, at least the bottom area of the shower would be tanked 😂🤦🏾♂️
Can apply in damp condition?
I'm not an expert by any means, but I wouldn't want to trap the moisture behind? It could cause lots of damage to your walls
Good Morning, when applying the Shower Waterproofing Kit the substrate must be solid, contamination free and dry.
I kind of had a similar problem, the window frame I was applying it around had condensation on it, do that mixed with the wps. Fingers crossed it turns out ok

Can i use this on a plywod shell? It's for use in a campervan. Thanks
Hi Alex, Our technical team have responded with the following "We wouldn’t recommend it directly to plywood for this type of application, however if the plywood was over boarded with a suitable tile backer board this could then be tanked using the shower waterproofing kit before tiles are applied." I hope this helps.
Using it on my campervan. I used a waterproof PVA on the wood, then the primer, then the WPS Magnum, covered it all with PVC sanitary sheeting. Did you end up using it on your camper Alex?
@@hennnnerz and how did it last?
@@tomkilmore7254 No problems, all seems to be perfect so far 1 year later
