I just wanted to know if tradetilers price of £35 for the 250mm is the going rate. ?

Does anyone use anything other than a spiked roller?

Correct me if im wrong, the spiked rollers purpose is to eradicate the air bubbles after each pour of slc? What problems could the bubbles pose to the slc or tiling?

Thats presuming the air bubbles appear after each pour? Is it the substrate that makes the air bubbles appear?

Thanks for any tech help with the above

hi gold,i have a spiked roller but i dont actually use it if im levelling for tiling

i think it would be more handy for levelling for vinyl installtions

More so for soft floor coverings but do help spread the leveller around having said that new levellers such as Mapei Renovation Screed is brilliant for finding its own level without even trowelling over..

As kilty has said, I think it's more for vinyls as bubbles can show through after fixing....

More for getting the air bubbles out floor resin paints..

I meant to put up a post about this a while ago but I totally forgot.

I spent the day with a weber rep a few months ago and we got talking about SLCs and methods for mixing and applying. Weber are now recommending a toothed trowel on a long handle, rather than a spiked roller. The problem with just smoothing it around with the flat of your trowel is that the water sits on top and it can trap the air under the SLC. the spiked roller is meant to release the air from underneath but apparently this new notched spreader is better and quicker at doing this.

I gave it ago (I just used one of my wall trowels) and have to say made a really good job of it. I have done this a few times now, I pick which trowel to use depending on how out the floor is and spread the SLC as if it was adhesive and the SLC finds a nice level as well a leaving a smooth finish.

Not sure if that is of any use but it puts a different angle on it

Worth a try next time..

Give a go, I was impressed with it.


P.S Please nobody try this over under floor heating

I use a spiked roller on all slc's. I was told that not only does it help to draw any air out, it effective at moving the slc around without leaving trowel marks and it increases the bond to the subfloor.
I like the idea of trowelling with a notched trowel though, especially on the smaller floors.

As for the price, that seems about right to me
