laid approx 90m2 of 600 x 400 natural slate on middle floor of a victorian house in edinburgh about a year or so ago. they a massive pain in the neck!
i don't know what tools you have but i used a ts60 to score the tiles as a guide to cut when i used a radial arm wet cutter(rexon i think) to cut straight cuts. makes it easier to see what lines to cut. i also used a plasplugs contractor pro to cut the more intricate cuts round door checks, kitchen units, fireplaces etc. the orange all surface marker from tradetiler came in very handy as everything else i used either didnt show up or stained the
tile. as said in previous post i opened up a fair few boxes and arranged them in bundles of thickness, keeping the thinner tiles for the edges or in cupboards. with the slate i worked with, there was patches of thinner areas on the back of some of the tiles which i flushed over with adhesive before laying.
you have to be sure that the full
tile is in contact with the adhesive on the floor, if there is any air trapped underneath the
tile will be subject to cracking if any considerable or frequent weight is exerted on it. this is why you should never "dot" floor tiles.
i used my 8mm rubi trowel for laying and the job came up very nice. i explained to the customer that because of the nature of the natural
tile they come in all different lengths, widths and thicknesses and that i would try my best to make sure the tiling work was flush as possible. the evidence was there for her to see.
as for your tiles you will need to clean any dust off them before fixing or they will likely "pop" as they won't properly adhere. the dust will stick but not the
tile. once laid clean over the slate, remove any pencil marks, then seal, then grout, then pick up some well earned dough. hope this helps. jus new to thisforum thing not sure how to upload pics yet.
