Grout, grout and grout

[Simon Dale]

As a professional tiler you would think I know. I dont !! Is Epoxy grout more flexible than a cement grout ??? I assumed that grout gives under stress. My assumption of epoxy is it adheres to the tile more than cement grout. If there is movement the tiles would tent rather than the epoxy failing. Thats why I choose not to use it. I do expect some stick so fire away Your never to old to learn or Im an idiot

Oh hahaha I was under the impression its less flexible once set.. Just impermeable, would be interested to know differently. Just on with a water factory at the moment and have 60sqm of epoxy on 200x200 dorsets to grout up this week

Was on tilerstalk and some young whipper snapper said epoxy is more flexible lol. I didn't know how to respond so asked the professionals on here As you say once cured its very hard

No doubt the plumber will be along soon to school us all

Im bal told me if a floor was done in epoxy and it moved the tile would crack before the grout joint would break . So maybe it's not flexible just stronger.

I’ve always believed epoxy grout is more flexible in years past but now with these new polymer modified grouts improving all the time not so sure

Better asking Frosty or the mastic man

I'd assume epoxy is more flexible. Stand to be corrected though

Not used it for years then in at the deep end
I'm sure there was a thread on here about using epoxy on a timber based wet room floor and it was advised against using it because of flexibility issues...might have just been a dream though

 

[Blunt Tool]

I’d assume if you used the admix to flexible grout then that’s the most flexible

I translated this found on the internet

EPOXY STUCCO - If Kerakoll and Mapei could recommend the stucco, they would certainly push you. It is a new market that are trying to create the two companies. Until a few years ago this type of putty was used only for certain particular situations (for example grouting of tiles / mosaics in saunas or in pools), but marketing will bring this product more and more in the residential area. Because it is interesting to push it to the producers: not all competitors are equipped to produce this type of putty and the selling price is much higher than the classic cementitious fillers. Because it may interest you: it is a much more performance putty, as it is MORE ELASTIC (useful for structural movements) and more resistant to abrasion. It is almost water repellent and resists very well to the chemical agents used in everyday life.

Me to I hate grout been thinking of using the Mapei premix

 

[Wolfie9878]

Always believed epoxy to be a lot less flexible than cement based.
Would like a definitive answer though

Which epoxy mate?

Which epoxy mate?

Mapei kerapoxy CQ tried to push for fugi bio but it was nearly double the price.. So it'll just take me twice as long instead

Apparently Epoxy does set more solid if you use that hard on you have for me to clean the joints

I hope you're billing for consumables as well as time mate. Good luck
