A little tip, if you spread your adhesive with a 4mm trowel and then roll the matting into this it will hold the mat down and helps stop the floating of the heating mats when you do your SLC pour.

Oh and make sure its flexi adhesive suitable for UFH and when using this method, fast set flexi adhesive is best unless you can leave it overnight before the SLC

yes allow a bit more than you need, its better to have to much id say 7 bags!!

It's loose wire rather than mats and I'm planning on using a hot melt glue gun to stop the cable floating in the slc. I'm planning on using Keraquick to fix the insulation boards to the timber floor, and keraquick to fix the tiles to the slc. I'm not used to Mapei so still learning which products to use. The Fibreplan is a bit dear isnt it, about twice the price of what I would normally use.

It is slightly more because it isn't made in the uk yet.. you can use any suitable SLC... The latex plan trade is ok..

Would be better to use Latex Plus additive as well if it's on a timber floor.
