Spiked roller or not ?

[2020Tiling]

Hi , I seem to be doing something wrong when I self level floors, they never are flat after I have used self leveller ? I recently self levelled over a chip board floor that had old adhesive stuck too it then over boarded with cement board and still had too build the tiles up with adhesive to make the floor flat? I used the correct slc and mixed it to the manufacturers instructions. Would a spiked roller help with the slc process? :smilewinkgrin:

Spiked rollers are for removing air bubbles... what you could do is make up a pin rake with screws and 2x1...

Generally slc's aren't really self LEVELLING but rather self smoothing, there's is a little more to it than pour and walk away.
Phil Hobson has recently posted a great thread on this subject you will find it very helpful.

And spiked rollers are more suitable for thin screeds.

self leveling is really self smoothing IMO.......two hits or use the batten method......like Phil.......In my time I have also fixed Drywall screws into a floor..........find your high point and work away from that with a straight edge.....screwing drywalls as you go....500mm apart.....when you are finished you will have the tops of the screws as level across the floor.....latex to them and bobs your uncle!........

that is my helpful post for the month sorted!!!.......hehehehehheheehhehe

what the hell is that contraption?........some sort of squegee.....with carbide tips?.......like the old fashioned tipped trowels?

That is a skid rake Lee ..

They are used like these ones lee ... good for bigger floors and pulling SLC to a said depth..

No, ur pant have skid MARKS
The skid RAKE gets them out

:lol:.......

nice vid Dave....but I guess I was right that they are like the old carbide trowels.....they have a fixed depth......and therefore will screed the humps and bumps of the floor less the "leveling" ability of the SLC......

its not for me......

 

[2020Tiling]

Has it got wheels on either site to adjust the depth?

I have the Regina pin rake but almost went for the skid rake, I wonder if you could use the skid rake on UHF?

That is my use for it as well .. as the 2 feet are round feet then it will not snag like a pin rake..

if you are "skimming" a flat floor it will do the job quicker than any other method...I am sure.........

here is a carbide tipped trowel....old school full bed trowel for those that have never heard of it.......almost the same principal IMO:

Try one mate, they are great for levelling/smoothing/sorting out duff floors!
Different to the carbide trowel as the adhesive didn't move, the smoothing compound moves about and slumps/levels into the dips if mixed nice and smoothly

I could never see how these trowels worked as they put no key onto the floor, yes you got the floors flat, but there are no teeth to bite the adhesive into the floor, quality leveling compounds seem to key themselves in.

Lee. the 2 feet are adjustable up to 20mm deep, so not fixed in-situ..

what I ment Bugs was.........if you used SLC and spread it about with a carbide tipped trowel.....the effect would be the same....IMO.......you are "pushing/ pulling" the slc to a fixed depth....and therefore by proxy you are following the floor.......but the slc will "smooth" a bit..............I am better off with my method........of trowel, roller, screws, datums etc............what with these new 50mm latexes and all!"!!!!

all the best lads...and TBH if its sorts you out then great.....we are all looking for a solid bed EH!

Okay Dave......it is interesting........but, I still think it is fixed at the height you set the "FEET"......the natural verlocity of water/latex is key......its great if the screed/boards are not that rough.......IMO....

Oh and I have been wrong before....and I will be again........ask my wife.........but please dont do it while she is raking the skid marks from my skid pants.....

all the best
