I have a wetroom and floor mosaic coming up that will be epoxy.
Last weekend on the recommedations of Spanish i bought the epoxy N C are now selling called Starlike. £33-2.5kg trade to give it a trial
As Gary mentioned earlier N C Have now bought the old Litokol epoxy starlike brand.
I fixed 2m2 of old mosaics up and applied to an area,washed off left for half an hour then reapplied,left for half an hour again and continued.
I could still apply the epoxy 1 1/2 hours later and still sponge over the first areas of epoxy without it getting bitty and pulling out.
As for washing off best to use an emusifying pad but i did try areas with just a sponge and it did easily come off.
I beleive there is also a product they sell in conjuction that takes any epoxy resin off as well.
Also there is a glitter that can be mixed with the epoxy as well.
An amazing product,very smooth finish and no sweat at all.
Interesting to see if they have a good colour for stone.
