Myths and Misunderstandings: Testing the water resistance of grout - TilersForums.com

[Rizzle from the Portizzle]

box is tiled and grouted corners are siliconed and it’s all ready to go i will fill it with water next saturday and the fun can begin


can we have a pole set up so people can say how long they think it will take starting at 30 minutes then within 24 hours then maybe two days then over a week

hi dean how big is the box L X D X H each litre of water weighs 1kg what size are the tiles used grout joints .what grout have you used .looking forward to your finding the best tilers will all ways question and look for there own answers .well done for showing others how to back up what they are told and say

Omgood god the guys just tiled a card board box Ray...real tilers can tile a box but are intrigued by the results, get a grip mate this is just a grout and sealing experiment..

Must be honest, I was expecting more grout. Just one grout line? Sure the water that will get through is going to dissipate and probably never even get chance to touch the cardboard?

I was hoping 6x6 or mosaics or something?

the water will not have a chance to dissipate there is only one way for the water to go and that will be the path of least resistance the rest of the box is impervious.

What grout?

Absolutely no idea but I'd bet my left testicle that it was either some he ( my landlord) had laying around or the cheapest he could find.
I've made an album which also shows underneath but I'm too thick to be able to link to it..

A big vote of personal thanks from me to Dean for this thread.

I am a die hard tanker! But with a mere 8 years in the trade my thinking has been formed by an awful lot of "industry" instruction. I like to see conventional thinking challenged and real time testing is the best way of doing this.

Remember reading tests done by someone on here to challenge the convention of always using insulation board with underfloor heating. That was an excellent thread too - first time I could fully se the practice supporting the theory.

Dean is also right to keep this discussion in the Arms. I don't mind how the test pans out, I welcome seeing the evidence of how water "proof" grout really is. There are an awful lot of unwaterproof walls supporting tiles in showers, and repairing rotten walls in untanked showers has made me a lot of money in the last few years.

I think posts like this make it worth being a member of this Forum.

Yeah I just can see how one grout line is going to allow enough water through to penetrate the cardboard.

It'll end up evaporating out before its managed to soak through the grout. And what does soak through the grout will disperse amongst the adhesive and not really effect the cardboard.

I've been diddled.

Do one with mosaics.

Can you find me that thread by any chance? We have a new tests forum category I'd like to move it to.
