Ditra laying methods

[Peter]

Anybody ever worked out how much adhesive per metre the voids take up? A metre per bag?

If we are getting in to figures,I can say that if you use a 6mm notch under ditra mat and cover the ditra top you will need approx one bag average adhesive for 4sq
when using a vinyl roller no problem with 4.5 mm rubi notch underneath.
the vinyll roller really comes in to play with the psi pecilastic.
Only use 3mm notch for pecilastic and the the job is really easy.i can offer a good saving to client with this product

I did the schluter training course along with Whitebeam ,schluter gave us a 4mmx3mm mosaic trowel to fit the ditra and kerdi down with and said as long as you get full contact that is enough

I concur....

Would be interested to know the coverage difference. Not entirely convinced that Ditra rubbed down by hand gives as good coverage as it would do if it's rolled and the adhesive is squashed more, even when mixed a bit looser. Ever notice there are some patches lighter than others? One for the testing team perhaps?

I did check the shading/100% contact issues with Schluter tech dept earlier this year(Using their supplied free trowel).They said this was normal and that 100% contact is not required.

Best thing I ever bought, laying ditra far quicker with this.

Schluter recommend 2kg m2 to fix mat and 2kg m2 to fill voids, I still use a plasterers float to lay, can get good pressure with this. generally dont fill voids first as good to use up rapid set thats going off to fill voids as your tiling

Where did you hold of that.......

Thats what I use, got mine off eBay for about £20

Most vinyl flooring / carpet wholesalers will stock these it's a vinyl floor and wall roller cost around £20. A lot less tiring than troweling the ditra/dural.

Got all the bits ready to make the Karl Dahm style upright roller now, will see how it performs. Should give good coverage with the bag of adhesive weighing the shaft down.

 

[White Room]

Schluter do say that the max weight for rolling onto the ditra which has a cement based adhesive to fix it down is 40kg......

 

[Peter]

20kg bag and a few kilos of pressure should be perfect then. :hurray:

Yep
