Shower grouting?

[vifferman]

Selleys No More gaps is not suitable for use around a shower or bath.
You could use a silicone sealant, but if you do, ensure you get a reputable brand with a mould inhibitor. I would use a Sika branded product as their mould inhibitors perform well.
There are a couple of Expandite products which we have found to perform well in the bathroom also Silaflex MS and Uraflex. Silaflex is a modified silicone and is paintable, very durable, sticks to a wide range of materials and doesn't grow mould as quickly as normal silicones. Uraflex is a polyurethane sealant and performs similarly.

Eggs Zachary what I would've said, if I wasn't too pharkin' tired to type it out.

I've spent all day fixing a leaky pipe in the house. Er.... actually the pipe was relatively easy to fix; the fact fixing it made the pipe shorter, and then I cracked the inlet on the toilet cistern took hours...
And it'll take weeks for the carpet and inside of the walls to dry. On all three storeys. Pharkin' stupid house. Should never have bought it...

for bathrooms but not for showers

So water proof, mold resistant SHOWER sealant putty?

get "mapai" brand silicone from a tile shop its a top line itallian silicone made by the biggest itallian tile adhesive, grout, silicone maker. i have used literally hundreds of tubes and never had a problem with mold but aside from that replacing the silicone wont stop a shower leaking if the waterproofing is shot

I thought the whole point of the sealant is that it kept water out from getting in and through the cracks? The floor itself is stainless metal, theres just some tiles in the lower half foot around the walls, and I was wanting to re-seal the seams.

thats a different kettle of fish but you still need silicone basically the tiles are a decoration in the shower they are there to look at and tiles, grout ,silicone wont keep water out by themselves

Hmm, I really don't know then.

In the building inspection when I bought this place it was commented that there could be possible water leakage to the floor or something, from the shower. However there was nothing to say why he had thought that. The only thing under the shower is concrete and dirt. I suppose some water could seep into the walls though. But there's only two walls it can seep into.. and one I think is a brick concrete wall with the garage on the other side. And I think the 2nd wall goes connects to the neighbors garage on the other side.

Mate, listen to what has been said. You start with a substrate this is either impervious to water or is waterproofed with membrane to make it impervious to water.
You then put a protectived screed or layer of grout over the membrane, you then lay the tiles and either grout or silicon the joints, using an approved sealant - the Mapai stuff mentioned is perfect. Selleys No More Gaps will NOT work.
The whole idea is that the water IS going to get under the tiles, hence the water proof membrane stopping it getting any further. Thus it depends on how old the shower is as to its method of construction. I would certainly never ever rely on the tiles to keep the water out. Same story as with some of this leaky building crap...people thinking that the cladding alone will keep the water out...bullshit, one crack and the water floods in. Hence I hate plaster houses with a passion. In the case of cladding, a cavity is needed to convey the water out and not into the house. Your tiles are like brick cladding - designed to get soaked through and make it no further.

If you hear anything said...PLEASE DONT USE NO MORE GAPS.

And- Good luck with your project.

go to your local tile shop and get some "Mapai" brand silicone its itallian and good and relativly cheap

Mapai cheap?!?! man you've been given the line!!! lol. It is good stuff though because you can match the silicon with there grout color too. RLA Polymers have this type of system also.

I sell silicone "Tilesil" which is RLA Polymers brand. $15 isn't too bad. Tilesil retails for around the $10-$12 mark. There isn't any distribution down in Dunedin though so there goes that :-).
