Addy going off too fast

[WetSaw]

Certainly can't do it here in the summer!!

 

[Stef]

If the adhesive is still "live" i.e hasn't gone off, I don't think there's a time limit.

Correct. Adhesive cures under chemical reaction & until it goes off then that chemical reaction isn't happening.

Top left tiles, 5/6 tiles are fixed with said addy, can come & dig out grout & try & lift them.
If you can I will pay you all your time, effort & travelling time etc.
That's how confident I am that they tiles won't budge.

So this thread started off
With a bad batch of gran fix
Then the tile guy got ripped a new a!.-hole for suggesting to use a mixing stick
Now we are mixing adhesive one day then using it the next
In cold and frosty conditions
Wow

 

[Stef]

Who said it was frosty?

 

[Swin]

What does it say on the spec?

Spec says use piece of 3"x2" wood ,I just checked the bag

Mix up a little bit of slow set addy & leave it outside & see how long that it takes to go off. You will be surprised.
Try it with rapid set also.
All drying times for addy are set at 20 degrees. What happens in the summer? Your rapid set will go off a lot quicker than it states on the bag so the exact opposite will happen in cold weather.

Wasn't warm here, if it was then I wouldn't have been able to use the addy as it would have gone off, set as it would have been warm enough to start curing.

 

[Dash J]

So unless you slept in your van last night you wouldn't know if it was frosty or not?

why take the chance with stuff that's been lying all night

 

[WetSaw]

Just stick your finger in it, if ii sticks to that it'll stick a tile!!

It was 2 degrees here last night.
Your not taking a chance, if it spins up with a stick or scraper or paddle without adding any more water then it's still good to go.
It cures under chemical reaction & that reaction hasn't happened because the cold is delaying that process.
The exact opposite as in the summer as the heat speeds up that process.

Old school, like it. [emoji1][emoji1]

 

[Dash J]

Yip I get the reaction jargon

It all sounds great coming from the tiling dictionary

I'm no having it tho,no for me I will leave it at that

I will stick to the way I do it and that's to stick tiles with adhesive that hasn't been left in the elements

 

[Stef]

I'm not saying you can do this with all adhesives but I've done it before with SetaFlex as it's got a long open time in cold weather.



This is what it states on the bag, if I mix this up & haven't used it in 3hrs then i should bin it?
I should give up tiling as I'm too slow. [emoji1]

So true stef,chemical reaction says it all,that's why don't use ready mix

 

[Dash J]

Unaffected by frost after setting!

 

[Stef]

Unaffected by frost after setting!

It needs to be zero or below to be affected by frost not 2 degrees.

 

[Dash J]

Is that you toeing the party line!why don't you use ready mix?
ready mix has its uses

 

[Dash J]

It needs to be zero or below to be affected by frost not 2 degrees.

2,3,4 degrees I still don't think its good practice,horses for courses mate,you think it's ok to leave addy in van and re use next day,that's your call I'm no having it tho regardless of chemical reactions
cheers
