Cheers for the upload

[@lythsian]

I wish I hadn't even started this renovation. What a pain.

[@suraphelbogale6563]

Thank you. Very Helpful.

[@sleimansamrani3773]

I would have started with a horizontal application on first coat allowing the vertical 2nd coat help any water that hits the wall travel down the wall effortlessly and not allow any water to sit inbetween the ripples

[@TheBoczk26]

What was the type of primer that was used?

[@RaidenXXII]

Hi, DId you put silicone around the puddle flange? Would the waterproof membrane stick on the silicone? I'm using RLA Commercial WPM Class 3 with fibre reinforce in the membrane. If I have 14mm silicone bond breaker in all the wall/wall and wall/floor junction including shower hob, would I need to use the polyester fibre reinforcement roll in those corners? What about around the mixer, spout and puddle flange when waterproofing down into the drain? I noticed the waterproof membrane becomes really thin on the silicone bondbreaker and some area I can see the silicone underneath. Would it be a problem if I apply the first layer too thick? The recommendation is 1mm after 2 coats but I"m thinking off doing 3 coats since it's the upstairs en-suite bathroom.

[@PlayGame-vz1pt]

Hi. If you apply more than 3 coats, is that make it more stronger or leads to peel off easily? I am currently doing my bathroom, as it's previous waterproofing failed and caused huge task and headache, I would appreciate from you tips if you offer, thanks

[@khuadinh78]

very good. thanks

[@antofa11]

with the angle around shower base...the tiler would kick it out of place as it could be too high or too low to be flash with the tile. use poly and even bandage on joints/corners.

[@jimmysotack2523]

Love waterproofing showers,wish I could do it everyday

[@francescaprizzon9773]

Hello, fantastic tutorial! I am about to redo from scratch a bathroom on a houseboat and am wondering if this process of waterproofing would be suited for wooden walls. I did not build the inside of the boat and haven't scraped off the current wallpaper from the walls, so I wouldn't be able to guarantee which type of wood it is, or if it's marine grade. What would be your opinion regarding general wooden walls? Thanks!! Francesca

[@julesbaumann6560]

Phone Ardex technical hotline ... I've used their products n the tech staff are friendly n helpful

[@7.62fullmetal9]

I just buy 50 tubes of no more gaps and brush that on, that should work right ? For a bond breaker I wipe on some stale Hungry Jacks thick shake at the join and I use their straws as a bond breaker coz we can get all them straws at Hungries for free just take them. So far my showrer has been in use for 2 days and no signs of any leaks, awesome !

[@jsaltirov]

🤔🙄🤔

[@PlayGame-vz1pt]

Hey, nice demonstration, may I ask what if you use more than 2 coats, I intend to apply 4-5 coats, is that would be Ok. Or the standard is two coats and I like to do waterproofing the entire bathroom wall and floor, as waterproofing failure caused a huge damage to my property. Thanks in advance for ur response.

[@ParallelEnterprises]

Manufacturers recommended two coats to achieve film thickness

[@blacksole161]

good video thanks for sharing.

[@scieadvance]

after first coat ,how much time to take second coat .

[@alfitty]

Hi Guys judt wondering if you can help me out. I recently started my bathroom rennovation the house is about 30 yrs old double brick construction and they used concrete to hold the tiles up on the wall. I chipped them all off with a rotary hammer drill but now the surface is uneven as some areas of the walls have bricks exposed due to the concrete bonding so hard to the cement it all came off. My question is can i waterproof directly over brick and the concrete patches even though the surface is uneven on the walls? And what are your thoughts on conflex tile adhesive. ? Any help would be great thanks in advance PS excellent video demonstration

[@leontorywalker8374]

Yeah SheSquats You can smooth it out with cement-based render before waterproofing

[@deano7375]

What type of tape is used? For a shower niche, is only the 12mm silicone required for the niche internal corners? Or should the tape be used as well?

[@MrHuddo]

+Dean O Black cloth tape sold in Bunnings... Really good adhesion and very versatile product. About $8

[@BeaglyO]

G'day Dah Dah What Black cloth tape at Bunnings is suitable? (Please provide a link if at all possible) www.bunnings.com.au/norton-bear-50mm-x-25m-black-cloth-tape_p1661568 Really need to get the correct tape! I don't need problems in the future. Thanks

[@timscott3921]

So are you screeding over the membrane? I get mixed info as to whether weatherproofing should be under or over screed

[@ParallelEnterprises]

In Australia the standard is below screed, however there is methods to be applied over screed

[@nisha145ns]

can I use this anywhere

[@Raymar651]

Hello what type of tape did you use gaffe tape , bond breaker branded, generic tape ??????

[@rldays9179]

That looks like just gaffa tape lol

[@nickalika]

Nice tutorial, I just wish you specified some stuff, like, what primer why use a primer, what will happen if you dont... same for the membrane, what is a good one to use, are there differences n product etc.

[@ParallelEnterprises]

Well all manufacturers have there own specifications and when abided to work well. As for this demonstration we used Parex Davco product which is what we suggests to our trades people. Thanks for feed back.

[@hsvxu6suzukihatch959]

Walt Heisenberg to

[@julesbaumann6560]

Use Ardex system ... Aust made, or use Davco but stick to 1 system

[@SVETOGOR1]

Please tell me the best mold proof compound to cover the gaps between wall's tiles and finishing? thanks!

[@chillnoobgamer007]

How many hours will it take before applying the 2nd coat?

[@misunyi2329]

24hrs. I watched another KZbin.

[@ParallelEnterprises]

Different products have different second coat apply time, it’s always best to read the instructions on the label.. with the k10 in this video it has a fast second application cure time of 3 hours, however this is dependent on the temperature and humidity at the time of application e.g. cooler winter days would extend this time.. a simple rule is a touch dry rule that means the product has filmed dry. Hope this helps

[@laccanvas]

what is that green stuff ....membrane...does it peel. Can tile adhere to it?

[@janeshi9425]

[@leontorywalker8374]

laccanvas yep, but usually bedding is required in the shower space, before tiling, and fully immersible glue is what you use (eg. Powder Mastic). The green stuff is Davco K10 Polyurethane membrane.

[@laccanvas]

cool. sweet.

[@dbassociates9744]

Davco k10

[@atjnr2852]

Good to dust walls first. If u dust the floor and clean it then the walls all the dust from the walls falls back on the floor.

[@ParallelEnterprises]

Good point 👍

[@leontorywalker8374]

I hope that wasn't silicone in the corners, because the membrane was K10 polyurethane. You have to use a polyurethane sealant like Sikaflex, under a polyurethane membrane. Also, bond breaker tape is required in the corners.

[@MrHuddo]

+Leon Tory Walker A neutral cure silicone is fine

[@lukeparker3561]

+Leon Tory Walker a 12mm radius of neutral cure silicone is the bond breaker. If you use sikaflex in the corners the membrane cannot realise as in bonds to it therefore you don't have a bond breaker and movement may result in membrane failure

[@waterproofawareness7794]

Technically neutral cure is the only sealant that is a bond-breaker, polyurethane is paintable and technically a fillet joint.

[@leontorywalker8374]

Ok, we'll this is from the Davco K10 Plus data sheet: "All cracks/joints, irrespective of their width, must be filled firstly with Davco Davsil (Silicone Sealant) or Sodaflex 603 (Polyurethane Sealant). Then 50mm wide polyethylene/polypropylene tape should be placed over the crack, ensuring it adheres to the surface." Incidentally, Davsil is not a neutral cure silicone filler, it's an acetoxy cure silicone (commonly acid cure). Personally, we always use polyurethane. By the way, I've never considered polyurethane paintable, I think what you might be thinking of is what's known as "gap filler", that's latex acrylic, and yes, don't use it for this purpose

[@waterproofawareness7794]

Polyurethane is paint able, just as acetic cure is, they must be left to cure before painting over them. We have painted over it without it being cured properly and it actually attacks the membrane through vapor release. AS3740-2010 states a bond breaker must be used so to be technical, as polyurethane is paintable, it is not a true bondbreaker, due to the membrane sticking to the sealant. Neutral cure is not a filler it is a waterproof sealant just as polyurethane is. Its clear by your response, as with most in the industry of these small gaps in the knowledge, which can lead to failures and technically if you had to go to court for a dispute, you would come unstuck. Its good that you are trying to do the right thing, but be careful as some reps do not even understand this also.

[@ramsh6800]

Amazing. Ramyash pd.

[@alfredoGarcia-lq3qq]

problem is with that water proofing membrane coating is the grout in tiles will not totally stick on that compound, and you are going to have a big problem in the future every day used.and the tiles will going to puff up or removed because that membrane have a mixture of silecone rubber.

[@hardcandy7112]

I did my shower in 2005 ,ahead of time ..

[@waterproofawareness7794]

Terrible silicone work, but at least you used the right product for a bondbreaker

[@ucdailoi]

I see that you did not use any sort of bedding tape to help protect against slight movement of the floor/walls.....

[@ParallelEnterprises]

We used bond breakers in the vertical and horizontal joints

[@alexcamarena7140]

No netting for the drywall or floor

[@newroom123]

Hi, what is the type of black tape used? Thanks

[@MrHuddo]

+newroom123 It's black cloth tape sold in Bunnings... Really handy stuff, I use it for so many things around the house and adhesion lasts for ages

[@mijit.859]

OK ! When your applying the water 💦 proof membrane, how 'thickly' should you spread it on the surface(s) ?? 😨

[@LukeChapmangoogleplussucks]

BubS7*7*7 T. At least 1mm thick

[@mijit.859]

Luke Chapman ohh 😲 ok fine! I thought 💭 it was much thicker 👉🏻Like 4mm 😨 Anyways Thx !

[@keithowens9242]

Why didnt you apply a primer or bonding agent to the shower floor??

[@ParallelEnterprises]

Primer must be applied on any substrate prior to application of waterproof

[@joanpetervincent6175]

is it necessary to paint it on so thick?

[@ParallelEnterprises]

You must achieve the minimum cost thickness to be effective

[@husdb1143]

Thanks I’ve made 37.000 dollars so far

[@theglennsnyder]

Please explain "This is an educational video and should not be used for instructional purposes."

[@FixitAll]

O my god how many extra work! Use simple and regular shower pan liner and it will stay with no problem for 30 years.

[@nickdryad]

What’s the difference between an instructional video and an educational video? Nothing! I suggest you guys watch a video on how to make video with good sound. But make sure it’s an educational one or more f you can’t find one, find an instructional one.

[@windygorge1]

duct tape on the seams? ummmmm

[@lukeparker3561]

+Dewayne M (Windygorge) There are specific tapes which can be used as bond breakers, duct tape is not ideal as it stretches and then wants to shrink back. Gaffa tape is ideal if you want to use tape for bond breakers.

[@karenbouncer6194]

+Dewayne M (Windygorge) why are you using duck tape????????????????/

[@lukeparker3561]

+Karen Bouncer please read previous comment. It is not duct tape it is gaffa tape. needs to be a reinforced polypropylene so the tape wont stretch and will allow the mebrane to release hence the name bond breaker. this allows the membrane to have a lot more flex in critical movement joint.

[@jasonsykes5558]

Gaffa Tape? Serious? Go buy the correct bond breaker tape.

[@SomeDumUsrName]

Duct taped joints. omG I've seen it all now. lol

[@kwtilestyle3563]

Lol

[@sprindustrieztz1015]

You sir cannot waterproof! Gaffa tape? Do yourself a favour and tape the mixer, also thats not a puddle flange, way too thin, too much bond breaker, and just 2nd coat the whole lot, should get it good in the first coat if you know what your doin

[@ParallelEnterprises]

Check out this video on KZbin:

[@keeran450]

Hey mate I've seen you commenting regularly and was hoping you can give me some advice? I've applied Waterproofing membrane onto my marine ply shower walls but wasn't aware I needed to prime first... I'm planning on using a polyurethane glue to fix acrylic sheeting to my walls. Do you think everything will be ok? To replace everything or remove the current membrane will be a nightmare...

[@rldays9179]

Hahahahahahahaha

[@dfs-ms9ij]

Some countries are so stone age in Tile.... It's no wonder they still pay with mud.

[@lukeparker3561]

One critical error. You need to vacum or wipe down with a damp cloth, ideally both. Brooms are a big no in waterproofing they just push fine dust around.

[@muzguz7276]

+Luke Parker I'm no expert but i couldn't understand why a vacuum cleaner wasn't used here as well. I thought maybe contaminants but that's not really a factor i think. I'll be using a vac and a wipe down with a damp cloth. Cheers.

[@antonshkabara3090]

This time I will do it manually with the help of Woodglut designs.

[@johnswann6826]

This is not how you waterproof. Duct tape is not bondbreaker dudes.

[@tclark108]

I wanted to watch, but the audio is unbearable.

[@1FishinAddict]

thats a lot of different layers... how about just use backer boards and 1 layer of waterproofing.

[@TOMVUTHEPIMP]

Because 2 layers is what you do.

[@leontorywalker8374]

***** No, two layers are required at least (refer to the instructions on your particular product). I'm not sure what backer boards are.

[@PowermanGustav]

Not really like LIP This is like what we had in 1990 sweden

[@TOMVUTHEPIMP]

Would be a lot less work if you put the roller on a stick and rolled up and down instead of side/side. Work smarter, not harder.

[@lukeparker3561]

the second coat is supposed to be perpendicular to the first coat as specified by most manufacturers. So yes work smarter... do it the right way the first time.

[@leontorywalker8374]

John Rambo Yes, the second coat is always rolled on 90 degrees to the first coat

[@robbiejensen3641]

As a qualified tiler, I can insure you that this is all wrong. You never use sticky tape when waterproofing. You shouldn’t use silicone ethier. I think you should brush up on your skills before posting videos on how to do something you don’t know how to do.
