Tile water absorbtion experiment

[Canyondust]

That surprises me. Would that not be based on the grout performance?
One assumes not all grouts are equal ?

I could tile some plaster board with 4 squares of wall tile, grout and then leave a wet sponge on top (all horizontal). Each day top the sponge up and take moisture measurements from the rear.

I edited the previous post to say the tray tiles are marble 50 x 50 (I think)

Ahhh so your an engineer, right. ?

I wonder what Billy Connelly would say

Engineer / scientist

I recall looking at BAL and Mapei the datasheets had very little info. I did speak to a 'technical' guy at Mapei as I was interested in grout permeability but as I can't remember any data I am guessing I got know where. I did set some Mapei ultracolour (what I put on the floor) in a plastic jam jar sized pot. Then removing the thick disc and seeing how long it would take water to pass through. I can't really remember but I think the whole disc darkened quickly.

Were you sat in your kitchen wearing pants and listening to Radio1 by any chance?

Sorry couldn't resist

 

[Canyondust]

Totally over my head I am afraid.

Radio 1??? Is it new ?

thanks.

Was merely enquiring if your 'grout test' was carried out under lab conditions or under the same circumstances to Geoff

 

[Canyondust]

Ah. I'm not sure quite as advanced as Geoff's mine didn't make it out of the bathroom.

I did try to get the data from a manufacturer I will try again.

To do it in the lab a defined test would need to be written. So does soap for instance affect this ? (I know it makes it happen faster).
I will have a think. I have someone who needs a project and to learn some measurement techniques.

There was a time .......
But now I will just say goodnight!

I think I can actually hear the tap-tapping of tile manufacturers adding your email address to their spam/ blocked contacts

Without sounding too disrespectful (which this will sound), I don't think anybody here is particularly interested in developing this further. A photo of me in my pants in the kitchen boiling tiles yes, but not a hypothesis on if soap affects water absorption.

You've been a good sport James, and I value your contribution to the forum.

 

[Canyondust]

No worries

I'm interested to see how a water laiden system absorbs water along the lines of tiles adhered to plasterboard and grouted. I stand on this type of system everyday so be nice to know what's really happening.

I will look forward to many more interesting posts.

Sorry I couldn’t find the pic of you boiling tiles in your pants Geoff, but I did locate this one from our trip to Andalusia last year.

Happy happy memories John. Looking forward to our special time together real soon!
