Great question @mrjarrodGill - There is no alternative method to the ARDEX STA/STB system. ARDEX Deckweb would not be a suitable substitute sorry!

@@ardexaustralia thanks for the answer , what happens if a small section of screed has broken off near the strip drain, what would be the best way to repair? or can the Sta bond breaker cover over that section before waterproofing?

Do you have a question @kiranvenky - happy to help

It is disappointing to hear you are dissatisfied with the performance of the grout @marvinmartin4692 . Could you offer suggestions as to how you believe it could be improved?

Good question @podden3863 - The minimum thickness of a bonded screed is 15mm. This means the height of the screed at 1.2m will be 30mm to achieve the 1/80 falls for shower areas. ARDEX do not sell the stop angles.

OK @marvinmartin4692 - ARDEX WA and ARDEX WA100 epoxy tile adhesives are more difficult to apply and are ‘stickier’ than cement-based tile adhesives. Your comments will be passed on to our Marketing Department.

Good question @digita1hero - We believe you are referencing the waterstop angle that is protruding up around the sides of the demonstration unit being waterproofed. This is intended to prevent passage of water from within the shower enclosure to the surrounding areas (including potential water travelling through the tile adhesive /screed). We have a number of visual resources that may assist in understanding the waterproofing detailing processes, including the link below showing how to incorporate a shower screen installation: www.ardexaustralia.com/pdf/cad/D23%20-%20SHOWER%20WATER%20STOP%20AND%20COVER%20ANGLE.pdf?_gl=1*bsh86z*_ga*MjAwMjc3MDM0NS4xNTkyMzQ4NDQ4*_ga_5BRGGQSHFH*MTcxNTIyNjQwMC4xMjgxLjEuMTcxNTIyNjQwMC42MC4wLjA.

Glad you asked @SLim-nw9wc ! kzbin.info/www/bejne/oqnSqYufmd11rpI

If the polyurethane is a paintable one then the STB would stick to it. The concern here is whether or not the polyurethane exhibits plasticiser migration. This is the act of plasticisers within the polyurethane slowly drifting out of the polyurethane throughout the life of the sealant. This can lead to softening of membrane coatings applied on top of the sealant. STB tape will help protect the membrane from directly touching the polyurethane. You're welcome re: the technical datasheets!!

Good question @geoffstein3896 - The main thing here is ensuring you are keeping the notches unidirectional. If you fan the adhesive or alter directions there is a greater chance you cannot collapse the notch voids properly and end up with voids. No specific requirement for this one but it is preferable to choose the best direction which will allow proper Tarver method notch collapsing.

Good question @ravinvijayakumare - Bonded screeds are generally applied with a bonding slurry coat consisting of a liquid polymer additive (e.g. acrylic or SBR - rubber latex such as ARDEX Abalastic or WPM405) mixed with cement. The bonding slurry is broomed thoroughly over the dry membrane and the mixed wet screed mortar applied over the still wet bonding slurry. The liquid polymer additive is also diluted with water and mixed into the screed mortar.

Good question @user-fh7ne1ls2u - I’m sorry but I’m not sure which part of the waterstop requirements you are enquiring about. Perhaps the link below will visually demonstrate the use of a waterstop in a shower recess: www.ardexaustralia.com/pdf/cad/D23%20-%20SHOWER%20WATER%20STOP%20AND%20COVER%20ANGLE.pdf?_gl=1*bsh86z*_ga*MjAwMjc3MDM0NS4xNTkyMzQ4NDQ4*_ga_5BRGGQSHFH*MTcxNTIyNjQwMC4xMjgxLjEuMTcxNTIyNjQwMC42MC4wLjA

Good question @brendonglennie6843 - ARDEX EG-15 epoxy grout is more flexible than the ARDEX cement-based grouts even if ARDEXZ Grout Booster is incorporated.

Good question @donnastein4946 - No this is not a requirement. Just for demonstration purposes. To be compliant with the Australian Standards, the active membrane must be applied to a substrate with falls to wastes.

Good question @thomasmorris9318 - ARDEX WPM300 is a moisture barrier/primer and on its own cannot be relied upon to address leakage issues. The leaking area needs to be located and repaired with a repair mortar such as ARDEX A46.

Please visit the product page on our website for more information! ardexaustralia.com/product/ardex-stb-tape/

The sealant is fine to use in this situation and priming was not necessary. No harm in doing it, but this application doesn’t require it.

CA20P and CA20P are interchangeable in this scenario. Both the older CA20P and the newer CA20P Plus would both be suitable for this application.

Thank you very much!

Yes, where the bond breaker tape is applied, the need for a sealant is eliminated. This will be a substitution for the traditional sealant to act as the system’s bondbreaker. Thank you for the question and for watching.

AS 3740 allows for the use of proprietary transition tapes in place of a bond breaker. STB tape falls into this category.

Glad you like them! The waterstop will generally be covered with the installation of the shower screen or an alternate material. The video does not reach this step of the installation. As for the junction, the use of silicone will allow for a greater mount of movement but this is not necessary. Application of grout in this area is suitable, albeit, if the installation encounters high movement cracks could develop in the more rigid cementitious grout.

Thanks for your question! What additional info do you need other than the finish shown over the drain in the video? Happy to help!

@@ardexaustralia If you were to screed above the waterproofing and then waterproof again would you have to use another puddle flange? Trying to avoid creating a wet sandwich type situation if the 1st membrane fails

@conp I used a puddle flange from bunnings. Waterproof the tile underlay and the puddle flange. I then use a piddle flange adaptor (also sold by bunnings) and screed around it. This adaptor acts as a second puddle flange. I then incorporate the waterproofing into that adaptor.

What is the slurry made of? Just a very wet screed?

Yes the ARDEX STB and STA tape can be used onto a self levelling substrate as long as this is primed first using the ARDEX Multiprime. Like all recommendations before priming you must ensure the substate is clean of all contaminations, including dirts, dust, paint etc. Once cleaned, the ARDEX Multiprime is applied. This is allowed to cure for 30 mins to 1 hour then the ARDEX STB and STA tape can be installed.

We really appreciate your feedback! We're onto it! Thank you for watching

Thank you so much for the feedback! We really appreciate your viewing and commenting.

ARDEX WPM300 can be used in a concrete pond, yes. Thank you for watching!

looks about 75mm

We used a 40mm water stop angle. As this size suited the needs of our project. There are other sizes available so please assess the individual needs of your bathroom renovation. Thank you for your question!

There are many possible reasons, and all are related to the drying of the grout and the underlying tile adhesive. This can be affected by the porosity of the tiles, the temperature on the day and air flow. Please refer to the Technical Bulletin: ardexaustralia.com/pdf/tech%20bulletins/TB130.014_Sources_of_Grout_Discolouration.pdf

Our technical service department strives to offer best practice advice to the tiling community. Thanks for watching. We really appreciate your viewing!

Great to hear!

Hi George, We still do not recommend this nor will the board manufacturer. The problem is the strength of the board which is unfortunately the same both sides.

@@ardexaustralia So 12mm blue board is weaker than 4.5mm villaboard that can be tiled on and has been used for years as such?

Hi Stanislau, At ARDEX, we say the fall needs to be where the membrane is, so you can put the membrane on the screed but not underneath unless the falls are already in place. The best thing to do for the puddle flange is to extend it so that the waterproofing membrane, when placed on the screed, can be run into it neatly. If you can't do this, and you HAVE to bond the screed to the flange, give it a sand, then prime with ARDEX P 9, and then apply the screed with a slurry coat as per normal. Should you wish to discuss this in more detail, feel free to call us on 1300 788 780.

The brickwork should be rendered prior to tiling as variations in the mortar line depths could translate to high variances in the tile adhesive thickness (to the point where shrinkage in built-out areas may become a concern). If the old tiles are removed and the adhesive is brought back to the original lime render then there shouldn’t be an issue with going over the render base. Just check that the render is in a decent condition (not drummy or falling apart). If compromised then the render damaged render should be removed and re-rendered before tiling.
