layering S.L.C

[andy allen]

could some one please tell me if its o.k to layer S.L.C,[in other words put a layer down wait for it to dry;put another layer on top] only i rang bal tech depo about this a couple of years ago and they said it was not recommended with there products,just wandering if anythink has changed since then, or if this is not a problem with mapei S.L.C.

[Alan.P]

As far as I know it is always best to lay in one hit, what depth are looking to go to ?

[garythetiler]

how deep a bed do you need to achieve ?

[Ajax123]

It is always best to do in one hit if you can. If you need it to be deeer than the leveller you normally use can go - choose a different leveller. There are dozens and dozens available. However in terms of layering I hope its ok cos I done three layers on my floor. It hasn't moved in several years so think it is ok. I did prime between layers with epoxy and laid thenext layer whilst still tacky.

[merlecollins]

Always wait until completely dry between coats and prime with something like Primer G if using cement based leveller.
I was alwasy told by the Mapei rep that you could use Fiberplan up to 30mm in one single pour and have done so without problem, yet when you read the Data sheet it says no more than 10mm per layer.....

[TF Ed]

as the boys said the depth you need is going to be the key to what product to go for..slc ontop of slc is not a good idea in my opinion..the bonding issue needs to be bang on and an epoxy primer would defo be the way id go to cover yourself

[Dave]

A slury coat will help in the bonding but some SLC's state that if applying another coat then do so before the first is dry...and slightly still wet'ish... just stiff enough to walk on..but as always read the spec..

[kaharrison9]

If it's the Bal multibase you can add a specific aggregate which allows you to increase the depth of the slc.

Has enyone used Level Flex? its a fiber slc. I supposedly goes from 0 to 50mm. Used it a couple of times, seemed OK. Time will tell.

I use the Palace fibre slc ,that does the same 0-50mm one coat

Never used that one Phil, but one I have used a lot over the years is Wickes Master High Performance Leveller If anyone can tell me that it's not Fiberplan re-bagged I'll be amazed A few years ago I mentioned it to the Mapei rep, who was curious as he said that his MD had been in talks with Wickes........

[doug boardley]

Ultra say it's ok to layer SLC as long as you prime it after it has been down for 24 hours

[merlecollins]

I've always waited till dry and re-prime before layering SLC, bt like Dave says some manufacturers stipulate you doing it whilst the previous layer is slightly wet, Ardex spring to mind

[penkhull]

I've spoken to an application manager about this, you can more or less always go layer on layer but if you let the first layer dry you must prime between the layers or you can go straight on top if the first layer is still slightly wet (so you could just about still put finger marks in it). My advice would be to let the first layer dry and then prime before you put the second layer on.

Althoug I'm pretty sure all the following companies do a leveller that will go to at least 50mm

Norcros
Tilemaster
Weber
Maxit
Ultra
Mapei

[Dave]

PCI HSP34 will level from 3mm to 60mm even on timber floors.

I have used this a few times as it is what my stone supplier has.

Nice to use and feels just like fibre plan but goes deeper in depth.

What does the wickes one smell like if that isn't a weird question Mapei grouts and ultraplan have an almost fruity smell about them

I thought wickes gear was Weber

[penkhull]

Not sure about that because aren't they the same group as tile giant?

Sort of, both are owned by Travis Perkins

Who are owned by Saint Gobain.

[Colour Republic]

Who are owned by Saint Gobain.

You sure? I thought that was Jewsons

[Dave]

Who are owned by Saint Gobain.

They don't own travis perkins john...

[penkhull]

Travis Perkins are not owned by Saint Gobain. Saint Gobain own CTD, Weber, British Gypsum, Isover, Jewson but not Travis Perkins, unless you know something we don't and if so I'm off to buy some shares!

[Colour Republic]

Just had to go a check and found out something I didn't know. Travis Perkins own or own at least some of mybuilder.com the lead generator site

[Rob Z]

The ones I use (by Laticrete) are OK to go over again as long as primer is properly applied.

[merlecollins]

Mapei grouts and ultraplan have an almost fruity smell about them

You've got to get out more CR mate

Travis Perkins are part of the same group that owns Tile Giant, Wickes and Toolstation
