3mm tub adhesive versus cement ad

[Dumbo]

Am I the only person that has read the instructions on these tub adhesives?.....they state a 3mm bed with a square notched trowel or use the spreader supplied. Also says open time of 20-30mins...although I know someone who used it for hours...will the whole tub really be un-useable in 20 mins?

So do you use 3mm trowel

A 3 mm bed doesn't mean you have to use a 3mm notch trowel.....it's what the finished thickness needs to be....so you can use a 6mm trowel and once the tile is fitted and the adhesive ribs squished then the final bed would be 3mm.
The 20min open time refers to the time you have to fit the tile once you have spread the wall to prevent the adhesive skinning over......it doesn't refer to the time the lids off the bucket.....although I wouldn't leave the lid off all night .

And I thought you read threads properly Andy 🙁
Haha

Open time is different to pot life!
Open time is the amount of time when it has been spread on a substrate, not in an open tub.
So, no, you're not the only person that reads instructions, its just that some understand it better than others.
