Browse Forums Bathrooms and Laundry 1 Oct 06, 2014 9:44 am Finally moving forward with my owner build, but before I get right up to this point I wanted to find out some more about waterproofing the wet areas, like bathroom and laundry (do you also do the kitchen ?). My questions... I would like to save some money and do it myself, but not sure if councils will accept that due any certification requirements ? Do you get a 'water proofing company' to do it ? Do all tilers have certification by 'default' ? In the bathroom, the waterproofing is done before the screed goes down or does the waterproofing go over the screed ? I'm in Logan City in the SE of Queensland if you have any recommendations. Owner Building at Jimboomba Woods in Logan City Qld.

Re: Waterproofing requirements 2Oct 06, 2014 12:08 pm I can't answer your first question (I suggest you talk to your Council building inspector), however if you decide to do the waterproofing yourself, then I suggest that you have it inspected before commencing the tiling. Water proofing materials are available at Bunnings. I put the screed down first before the water proof membrane. This way I had a smooth surface to apply the membrane to. I read up on the wall sheeting manufacturers instructions (I used Villaboard). These require a pvc angle to be installed behind the villaboard in the corners of the shower and the villaboard must not be fixed through this angle (the nails would put holes in it). A second stud is required to fix the villaboard to. I missed this requirement when I made my wall frames so I had to retrofit these studs. If you plan to do the waterproofing yourself, you need to familiarise yourself with the extent of waterproofing required. I varies depending of the type of shower that will be installed. Also there is an important difference between the requirements for "water resistant" and "water proof". Waterproofing is not required in domestic kitchens, only a "water resistant" installation is required there. Re: Waterproofing requirements 3Oct 06, 2014 4:30 pm Tilers are not automatically approved to Waterproof they need to do a course for this, just as waterproofers are not always tilers 2 different trades. I would go with a professional as waterproofing is not that expensive to get done but if you mess it up its a very costly mistake. Some tilers prefer you to waterproof prior to the screed going down as it is less likely to get damage while tiling. If it is a new build than you have a smooth easy to work with surface. If you are having a semi frameless or full frameless which are classed as un-enclosed showers than all the floor area needs to be waterproofed including an angle at the doorway entrance to prevent any water from spilling out. The money you save by doing it yourself will probably only be a few hundred, its really not worth the risk. Re: Waterproofing requirements 4Oct 07, 2014 8:34 am After seeing some of the shocking waterproofing jobs done recently on this forum by so called professionals I'd say do it yourself. That's what we worked out years ago when doing some bathroom renos and getting cowboys in. Some of them were hopeless. It's not hard if you are methodical and take your time. We also used to waterproof before the screed went down as a lot of the tilers lay the tiles the same day they do the screed. Stewie Re: Waterproofing requirements 5Oct 07, 2014 9:06 am Thanks for the tips guys. I'll chase up the waterproofing requirements for Logan City, and see where I stand. I'm pretty confident I can do it properly myself, and knowing it should be done before the screed, makes it more convenient to me . I can simply follow the directions to the materials 100% and give more than the recommended minimum times between coats.... do it once, do it properly !

Re: Waterproofing requirements 6Oct 07, 2014 11:47 am There are any number of guides out there. One of the better ones I've referenced for a few people is one by Hardies - James Hardie Wet Area Construction Application Guide November 2012.pdf http://www.google.com.au/url?q=http://w ... LYt5a4jTHg Stewie Re: Waterproofing requirements 7Oct 21, 2014 7:31 pm Its regulated in Qld, The certifier will require a wet seal certificate. So you cant do it yourself. Look in Yellow Pages under Waterproofing. Some tilers do have a wet seal licence. A bathroom will cost $500+ (<$100 for the compund) This the the floor sealing to prevent ingress if the bath overlflows.....other waterproofing say on the walls you can paint on yourself.

I'm in Logan City in the SE of Queensland if you have any recommendations. You will need to have it done by someone qualified who can issue a certificate in QLD. There's lots of companies to choose from, shop around and get some prices. Essentially they all have to certify there work so don't be scared off by horror stories. No not all tilers do waterproofing. There seems to be a different school of thought down south but the general practice in SEQ is waterproof before the bedding goes down.

Re: Waterproofing requirements 10Oct 22, 2014 1:02 pm As an OB though in Qld, can't you do the waterproofing yourself ? I can understand if he was going to sell the place within the statutory guarantee time he'd need someone else to certify it.
