    You say that, but seen other posts saying the Sigma is just as inconsistent.

    Dry cutting porcelain tiles

    I'm fixing about 90 metres of 10mm 800x800 porcelain tiles at the moment, using a Rubi Tx 1200 cutter. As per usual with large format porcelain, getting clean consistent cuts is very hit and miss. Decided to change my normal 22mm wheel for a bearinged version to see if that made any difference...

    Limestone Discolouration

    Hello Pete, just replying to your post after long telephone conversation, obviously cant say too much but staining resolved by customer with Wexa after Instarmac site inspection. As explained on phone, customers own results from tests resulted in a satisfactory fix. Although contradictory to...

    Limestone Discolouration

    have got Ultra coming to site this week, and am meeting the builder again to run through the floor construction for possible faults there, but testing the tile on a dry screed with same adhesive will be a good indication. There were some boxes and general building items left on the screed...

    Limestone Discolouration

    hard to nail this down to one problem, think its a combination of two or three of the above, the screed seemed absolutely dry when i first looked at the job, and the builder that Ive done lots of work for before was happy that the screed was dry enough to tile, I didnt, and have never used a...

    Limestone Discolouration

    dont know, it hasn't been mentioned, the grout and sealant were supplied by the tile suppliers, and there were two bags of extended set adhesive put with the supplied materials. I thought the adhesive was sent by the tile suppliers, as the recommended adhesive, and i bought more of the same to...

    perhaps not every day, but yeah this game keeps you on your toes and bites you when you become complacent. Just cant take anything for granted.

    Limestone Discolouration

    agreed, often builders offer the customer the option, and depending on budget the customers have the final say. Unsure of the details on this particular job, but you're right, ultimately it has fallen on my shoulders when shortcuts are taken.

    Limestone Discolouration

    Thanks Chalker, that makes alot of sense, will check with the builder that the UFH was tested before hand, I must admit I cant remember whether I asked, to be fair with their experience they should know. Do you think there would be any staining if the screed is the issue?

    Limestone Discolouration

    no, I didnt skim the back of the tile, used a 12mm notched trowel on a shallow bed, some of the tiles were back buttered to adjust heights, hence in places you can see trowel marks coming through, once again although not text book, have been laying stone for twenty years and never seen anything...

    Limestone Discolouration

    agreed, wont be using extended set adhesive again with stone, although states on the bag its suitable for natural stone, manufacturers claim it will dry eventually but im concerned it may stain or discolour the tiles

    Limestone Discolouration

    Hello guys, just fixed 20 metres of 15mm 900x600 tumbled limestone to a screeded floor with underfloor heating using Ultra extended set white flexible adhesive. When I returned to seal the tiles there was a noticible discolouring to the tiles which I put down to the moisture still coming through...
