He did Dave the technical support boy and i even questioned him when he said it thinking how or why would you prime a rubber membrane mat!! needless to say i wasnt convinced so continued buttering. Take it youve used Mapei Ultraplan renovation fibre enhanced screed, easy to use, solid...

Really i do ilke my job when things are flat!!!!!!:lol:

Apologies Dave, I should know better:oops: 700 kg is a good effort though infact thats shocking but think your all as usual right should have done that first. Boy at mapei said to lay slc on top of dural base after priming it but was in the middle of it by then, maybe the next floor which is...

Just home after one of those days. Pitched up to tile floor and lay Durabase and guess what no one in so hang about for an hour and finally get in! noticed while i was checking my levels that the floor was off it bits about 13 mm and had a hump in the floor. Figure id lay durabase as normal...

Thanks I Will do, ply down at mo so imagine slc will go down over ply where needed then once dry ill lay the dural and tile as normal from that? In general What thickness is possible?

Point taken.:oops: Just I've never used slc before and don't want to balls it up! Anyone any tips if I need to go down that route?

Yeah Merelecollins I have saw the floor in question al be it it was a few weeks ago. The building is an oldie too being renovated but I remember the floor as a whole was quite flat altho I think it may be running off toward the back corner and was just wondering if I could build up with keraflex...

Quality thanks Dave. Havnt saw many 30mm trowels though?:smilewinkgrin:

Have a corner of a room that slopes off and Im aware mapei quote that keraflex maxi will bed to 15mm, now what Im wondering is that a finished bed thickness ie once tile has been layed or bed as in trowel notch size ie 10mm round notch trowel?:mad2:

Have just layed porcelain floor and have been told by supplier that the black polished porcelain floor tiles have transport wax on them to provent scratching etc. Ive used a topps product to try and remove transport wax about a year ago and it wasnt good so am thinking about one of these 3...

Yeah like you say you cant turn down hundreds of houses as thats a good job lot and if everyones aware of any issues that could occur but still want to go down that road then what can you do? Nothing really. Although not ideal if floors are not solid , kind of the golden rule, could now with...

Hi Alan, glad to hear what I was hearing from topps is true. Don't understand why it should fail though, If floors solid ie no bounce and addy is suitable for use on chipboard such as keraflex then the Matt will bond well to the chipboard floor and with the Matt once layed waterproofs the sub so...

thanks all for the advice, I realise matting is to reduce the risk of lateral movement and because of that im going to use it on every single floor i will be tiling from now on no matter of tile type or sub. The only thing that will chage will be wheither or not ply is also required and that...

Hi Captain Slow, I realise its an expense i just want it to be right but suppose if your 100% sure of no vertical movement the matting could simply be layed on chipboard cutting cost. Dont see any need for backerboards in any floor application as they dont add strength to a floor and matting can...

What are you starting Doug,LOL My ideal is going to be, 1. Ply floor no matter if there floor boards, chipboard etc everything but screed 2. Lay mat on all floors no matter of tile type using flexi addy 3. Lay tile onto Dural using flexi addy 4. Grout and done...

ok , 4mm for bedding down mat and an 8mm/10mm depending on tile thickness? Dave do you use a squared or round notched trowel?

For anyones thats used this stuff any thoughts on best trowel bed thickness when using any membrane?

Yeah I totally agree with you Dave. I usually have my joiners ply the floor before I arrive and then tile onto that but think maybe a better idea is to continue to have them ply the floor to ensure its deflection fre then use Dural on all floor jobs ceramic ,porcelain and stone then once again...

Yeah Stewart it seems that this could be the future from what i was hearing, I mean if the floor is bounce free and your flex addy can stick o chipboard why shouldnt it work?? Dangerous place my mind.....

Thats what the manager said, even went to 2 stores because i didnt beleive it either but both said as long as no vertical movement its what there doing down south.
