Mapei fast setting tile adhesive

[fido69r]

Right....Don't want upset any tilers,but...is there any way of slowing down how fast this stuff sets? Yes, I know they do normal stuff, but found a 20kg bag of it in the shed, and I'm not the fastest in the world. I was buying ready mixed, but it was costing me a fortune, and there's enough of it to finish this job. The mix ratio is about 2-1, but what would happen if you added more water? would that slow it down or alter the adhesion, or worse....thanks.

if you found it the she it maybe out if date

Worse - but you already knew that!
Altering the ratio guides will invalidate any guarantee, it's fast set for a reason.

If you were to mix it with ice cold water it may slow it down but as @JulianSidney I suspect it has gone by it sell by date and that is why it is going off so fast .

 

[fido69r]

It's dtill in date...but to me 20-30 mins is fast...I meaan, it gets harder to work with after that..

Mix up smaller batches!

 

[Andy Allen]

And get all your cuts done and tiles ready to lay before you mix....

Would Isomat AK Rapid Flex C2 FT S1 be any good?
It has got pot life of min 90min
And open time 20min, you can grout floors and walls
after 1-3hours.
Acorn Tiles in Hemmel Hempstead stocks it.

If it's quite an old bag it will be slower anyway. Age does affect it.

You don't agree Julian?

I mixed a bit up today and layed 3 tiles to test it. mixed 1kg to around 300ml of water. time will tell...but once the tile hits the wall, it seems to dry quite rapidly. Need to get the tile right first time.

Ceramic tiles?

Have you primed your background with an acrylic or sbr primer . If not that can slow down the drying .

You don't agree Julian?
