I have seen various posts here concerning some waterproofing that should be done before installing tile in a tub/shower surround. I was under (obviously incorrect) the assumption that 1/2" Hardi did this. So to waterproof before tiling I need some waterproof membrane over the Hardi? Or a brush/roll-on material? What works best? I only want to do this once :^)
its a good product
Yup, the Kerdi is the best thing to use.
Now, if you don't want to spend the money and have more time than cash you can always remove the existing Hardi, put up a layer of 30# felt and reinstall the Hardibacker.
But you need to have some form of liner as neither tile, grout or backerboard is waterproof.
Thanks guys. Frodo...I nearly had a coronary...your link took me to the full shower base kit for $775. Found this instead:
Are there decent installation instructions that come with this product? How easy is it for a 1-person install or do I need a 2nd pair of hands? In the picture at that link it appears there has been some mudding performed after install. Wouldn't that br better suited to do beforehand?
Jaybee...Hardi isn't up yet. Better option here to put it up then apply Kerdi or something else? I have time as this is a guest bathroom with very low use.
Jabyee...did further research and found this on 30# felt:
This is very appealing since it doesn't involve nasty liquids and thinset and such. Does 30# felt provide similar protection that the more expensive alternatives provide? Any caveats to be aware of?
Since your backer is not even up yet, I'd go with the felt liner. As your other link says, it's been used for years and does the job. Even if you have to buy a full roll of 30# felt, it only costs about $18. Go with 30# over 15# as the 30# will seal around any nails or screws better plus will be less likely to tear during the install.
it's more expensive, but could he use the rubberized roofing material with the stick-um already on it? It's wide enough so as not to have seams and will last a loooong time
New product like Kurdi but less expensive Called Trugard check their website
