I am about to go and dig up my SLC - rebag it and return it to Weber!

I would be priming the first coat of slc before i laid a second at such a thin coat.

Yeah me too, there are some slc's that can't be done in 2 hits though that's what made me think. Each one seems to have it's own set of instructions!

hugo,it will be easier to lay a thinner coat 2nd attempt on a deep fill

so although it looks crap just now you may find its much easier next time,estimate your materials is my advice to your customers so you do not get caught out

I've just read your thread.

Reflecting on my last one, I will probably go for the thin 2nd coat. I had spent so much time getting those screws level as well. Obviously the 2nd coat will have to start again from the far end and work back. This means the job will take twice as long before I've even laid a tile.

It's my own house - not a customer, so it's not as if I've lost money on the materials so to speak.

My only concern about a thin 2nd coat all over is that the far end of the floor is pretty good on the whole, apart from that 3mm variation over 6 ft. I don't want to screw this up as well.

If I go for a 2nd application over this mess, how do I know I'm getting it level?

I have absolutely no confidence in my ability to do this now.

if its only 3mm just make it up with addy then hugo

Just worry about getting it flat.

How do I get it flat.

I was actually using a 6ft derby on it dragging it in all directions.

the Weber guy actually suggested I walked in it if necessary to access areas and flatten them out.

I use a 600mm hand held spreader just to move it about...

Some dodgy advise there.

600mm hand held spreader. Do you just agitate it or spead it in the same way you would tile adhesive?

You're not wrong about the quality of advice. So far it's been Tileforums 1, Weber 0.

I have very little faith in Weber now. Two of their employees I have spoken to have contradicted each other. Their coverage is obviously wrong. I worked it out to just over 6 bags so I got 7. The first mix was mixed exactly as stated and was too runny.

I'm going to be having words tomorrow.

Thanks for all your advice, and that's to everyone who's contributed.

It is really disheartening when I can't even get this right. I'm experiencing another major doubt about my abilities I'm afraid and it's not good.

 

[kilty55]

hugo how many times have you laid slc? its not something thats going to be spot on 1st or 2nd attempt like everything you need experience with it

dont batter yourself over it,its fixable have faith you can sort this out,fill the void tommorow and just use adhesive to overcome the 3mm deficit

With the spreader just pour the slc and run it over the top but not in a heavey motion, just to move about but I've never used weber slc.

...and I would not recommend it. Although I will probably have to use it again to sort this problem out. The product is probably OK, it's just Weber's misinformation.

I think from memory it calls for priming if a 2nd application is applied more than 24 hours after the first. I'm planning on doing it tomorrow, so that should be OK. Having said that some SBR on there wouldn't hurt I'm sure.

And Kilty, I think you're right. It's not the first time I've used SLC but I've not used it for a while. The last time I used it was in our kitchen for pretty much the same purpose. The reason I had limited success with that one was because although I wanted to spend more time levelling the floor out the wife just wanted me to get it done. So I didn't go back and do a 2nd application, which I regretted.

Using slc 20 years ago was a nightmare and rubbish, there is some good gear about now though.

 

[kilty55]

hugo the best one i have found that actually almost self levells itself is mapei fibreplan its expensive but better than any other ive used

 

[cornish_crofter]

This lot has cost me £xx.plus vat a bag. So for £xx odd I now have this mess. Not pleased at all. I've now got to chuck more money at it to sort it.

It's only a conservatory 2.6m by 3.5m. I'm guessing that Weber are a little optomistic on their coverage.

I get Ultra 2 for £xx, good as gold
