Can only recommend that you think about getting a professional in. They are cheap compared to the cost of water damage repairs and cheap compared to the overall cost of the reno too.
Cheers

A lot of the cost is in the actual product. I just finished my upstairs bathroom reno and we used a blue coloured product. I would have to speak with my mate to find out the name. I did nearly all of the work myself which included glueing and screwing asbestos cement fibre sheeting back down as we replaced all the plumbing. I thought I had done a good prep as I was once a tiler however my mate spent 5 hours touching it all up before installing a bond breaker and priming the surfaces, then we rolled/painted on the blue stuff bieng absolutely anal in the corners to avoid pin holes. If it fails he will look after me.
If I wasn't confident with him I would have payed a waterproofer who is insured if it fails. It's not cheap to totaly redo a bathroom reno especially if you use particle board as the wet area one will still swell.

I was hoping I could do it myself. I only have a small area in the shower which needs to be done.
A friend mentioned that Sika have a suitable waterproofing agent?
What is the bondbreaker and primer for?

Andy,
You don't say what substrate the tile will be laid upon. Concrete slab? Wood?
Uncoupling describes a way of compensating for the natural movment of the substrate versus the tile. A suitable uncoupler will have enough flex so that expansion and contraction of, for example, a wood substrate would not correspondingly move the tiles above it, causing cracks. Take a look at this website for more details:

In addition, absolute waterproofing is a necessity. Good luck.Cheers,
Bob

The walls are wet plasterboard and the floors are particleboard over timber joists.
I have attached a picture of the bathroom.

Never, under any circumstances, take a sleeping pill and a laxative on the same night.

Yeah- you can go for the professionals if you want, but waterproofing is not difficult and can be done properly as long as you are thorough and follow all instructions.
I just finished my first bathroom reno and did all work myself (excl water and elect) without any problem. For the waterproofing I used Dribond Liquid Flash- a light grey 'paste' that is painted onto the walls/ floor in two coats. It dries to a rubbery membrane that should be up to 2.5-3mm thick when dry. You can also use a (I think) 25mm wide fibreglass strip that comes in a roll of several metres to use with the membrane for flashing. It is laid into a coat of liquid flash and then another layer painted over the surface.
Liquid flash is made by Construction Chemicals- check the net for website and info brochures that provide info on how to use it. IMPORTANT- follow all instructions to every detail.
Hope this helps

Thanks Danger. I'll check it out.
I was wondering if water does get behind the tiles and it is waterproofed, where should the water drain? Is there a need for a drain hole in the floor??

The waterproofing goes into your floor wastes.

Hello All,
I have just done my bathrooms with "the blue stuff" called Gripset. I have brick and render / plaster so not toomuch trouble. The surface was a bit rough with concrete, so brush was nost effective. Gave mine 2 coats and also used the same branded binding tape to go into the susceptible corners.
You can buy it from Bunnings in a 10lt for $150. Don't be cheap, slap on liberally and do a couple of coats. It can also be rollered, but is very thick.
Cheers.....D

Michael, I have used waterproof plasterboard in the bathroom, and intend to waterproof in the bath/shower zone all the way to the ceiling.
