Heat shock pre tiling

Recommended Posts

Evening all,

 

Our slab was poured about 2 years ago now & with tiling down stairs now looking imminent I have been advised to heat shock the slab pre tiling (UFH).  Starting off by increasing the temp by 1 - 2 degrees a day up to a max and then hold that temp for a week and then drop in back down by 1 - 2 degrees a day.  The only snag is that no one seems to be able to tell me what the max temp should be, today I put it up to 23degrees - I can't see us every running it warmer than that.  Does anyone know how high we need to take it to?

 

Thanks

Just to the most you'll ever see, so if 23 was producing the desired output then you're done. TBH after 2 years I doubt if it'll make a blind bit of difference as that's pretty much 'cured' now for sure.

Tbh I'd leave it a bit longer before tiling...

Definitely. 

Can’t be too sure eh ? 🤔😆

15-20 years and @Onoff may be free to tile it for you.........

I'm pretty sure its as dry as it can be - the tiler is just worried about expansion ....

 

I will take them all up to a room temp of ~ 23/24 - hopefully that will be enough.

 

The drive from Kent to the Midlands will reduce his productiveness a bit I suspect.....
