SLC Methods

[Peter]

What method do you all use for self levelling and how many hits do you do on a bad floor?

Wouldn't be my strongest suit so interested to hear. Usually just trowel out and pull a straight edge over and fill in the dips as I go along. Hard to get a good result in one hit though. Forming skids/runners seems like a good system but looks like it'd use 3 times the SLC.

Do you find that some compounds are better than others or is it all in the technique?

Usually 2 hits with pin rake and spiked roller, shutter off area, pour slc, work in to corners then pull back with pin rake. Webber is good, stop gap 700 is good, mapei is good,ardex is also good. Grangix is rubbish!

Tilemaster levelflex is great too

As Neale for me, levelflex is great with spiked roller

Used spiked roller for the first time on my last big floor job..Fantastic tools.

here you pete
a video says more than text...they are using a pin leveller to gauge the depth and a spatula to flatten off and take off the surface tension...

theres a few different methods i use depending on the area and obstructions....its very difficult to actually level with slc unless you use preset runners but this vid is a good example of how many of the lads i've worked with go about doing it.

:lol::lol::lol: God i had to go for a coffee break watching that ! what a spanner nice-one phil

 

[White Room]

I made a cuppa waiting for him to mix that lot:sleep:

Dave, Mark, this guy must have some big price in on this job.:lol::yikes:

This is one way I lay slc, I have put it on before, but it works for me. Just to make clear to any new guys, Screeding (sand & cement) is a totally different skill to laying slc. This is one of many ways to get slc down.

after speaking to yourself and ed , I'm aware the word screed can be loosely used. Its an art in itself!

 

[Aston]

hi mate
i dont think screeding is an art. theres a few techniques that require a bit of practice but any tiler worth their salt could pick up screeding with a bit of practice. i put a video up once from csc screeding that demonstates screeding really well. i'll see if i can find it.

here it is....just follow what this guy does and you wont go wrong.
you can even see the expansion foam strips around the perimeter. all as you need to do is exchange that tripod and pump for your wheel barrow ;0)

i like the things they had on there feet in ed's vid, good idea..

 

[The Legend; Phil Hobson RIP]

Cracking vid Ed I never knew I was a technician we used a pump in Texas, but mostly ready mix with 12 hour retarder. here is a vid of the old way hand mixed, only a small area but gives us the idea.How to Tile & Grout Part 2: Screeding a Floor, The Best Way to level a floor with sand and Cement - YouTube

 

[The Legend; Phil Hobson RIP]

Ignore the sand bit, we used zone two grit sand/Mersey grit. The vid is very unprofessional by todays standards, but I just wanted to show the old ways, before pumps and ready mix.

Interesting posts. Does the pin leveller smooth out flat or does it follow the floor?

Did wonder that?

 

[The Legend; Phil Hobson RIP]

Follows the floor guys ,that is all it can do, I tried the spiked roller, absolute waste of space imo, I could have got the floor flatter if I had subbed it out to Stevie Wonder just mho, there is only one way to slc a floor and get it flat, and I've already demonstrated it other than that you are chasing humps and bumps until the cows come home. A sand & cement screed or a pumped Anhydrite will give you a flat floor.

Sorry if I seem a bit grumpy, just been reading some dumb peeps posts.

Not seen you on here lately Phil but used your technique on a big floor and it worked a treat!
