Hi, Im starting an 80 M2 floor in the next week or two, which is to be layed on top of ditra matting, now ive done a few ditra matt jobs in the past n ive always had problems trying to mark lines on the ditra matt when im setting out! has anyone got any tips to get me round this please?????

A china graph pencil works.. or chalk lines and hair spray over them to prevent rubbing off.. but i use a china graph pencil

you can flat out some rapid adhesiv and let it go off to give you a surface to chalk lines down on ,i have heard of ink filled chalk lines manufactured to mark out on ditra but have never actually seen one with my own eyes

now that aint a bad idea, putting rapid down flat to markout!! why didnt i think of that?? ive used ink in chalk lines in the past the only problem was its splatters everywhere and is very messy, but i was using a powered dye that is normally used for clothes and just add a little water and the only china pencil ive got a the min is the same colour as the ditra matt ha ha so that wouldnt work unless i get a black/blue one, but thanks alot for your answers it'll take me a day to lay the ditra matting on its own so whatever adhesive ive got left at the end of the day i'll throw down wherever im roughly starting from the next day

We use Sharpie markers, and the hair spray trick is great as well.

Gary, the Japanese chalk boxes are the ones that a lot of guys get here. I think the brand name is Tajima.

Pity we hadn't a laser to line and slightly burn into it,lol.
patent quick

I use my laser and a sharpy to mark it out.......

Quick drying matt white primer in an aerosol.

Sharpies are the way forward, loard of different colours too

a few of you are saying use Sharpies! what are they?

It's a permanent marker pen. It will come up if you google it.

Vern the good thing about Sharpies (besides the color selection as noted by Scott) is they are available in different widths for the tip-super fine all the way up to a super-chubby marker.

What if you need to do a chalk line over a long distance though.

Use pesalisic beam and blue chalk it's a lot easy lol

Doug he has a lot left from his younger days

you could try using pecilastic. it does same job as ditra acting as separating membrane but is only imm thick and you can flick chalk lines on top.
quicker to lay as well.

Karl Dahm do the ink lines, ask Dave at trade tiler.

Put dashes every so often along your laser line with Beckhams weapon of choice then join them with your bead
