Hi , I have a question on addy coverage. Im laying 15m2 of 600x600 large format tiles and am wondering if anyone knows the rough coverage id get from a 20kg bag of addy ? I plan on using a 15mm U notch trowel for the bed.

I was thinking maybe 3m2 per bag but not 100% sure.
Any ideas??

Thanks

with a 15mm trowel I'm assuming it's a floor, off top of my head you'll probably need 3 if substrate is flat

I would say 3 mtrs a bag as well with a solid bed 15mm trowel..

yep, sorry phone bing bonged as i was typing, as Dave, meant 3 sq m a bag

Cheers guys thats great, Thanks for your replys.

Have been looking at other posts there and its made me think about something else

On a 12mm screwed to death plyed floor is a 15mm bed over kill should a go with a 10mm round noth trowel?

As long as you are getting a solid fix 100% coverage then it is upto you really.....bed your tile and re-lift and see what covergae you are getting,,if not enough then up the notch size..PTB flexi is good for 600x600

I get 2 mts per bag of PTB on a good floor solid bed you would get a little more from SPF :Pete

Thanks for all your replys
