Exterior leveling compounds, what is available?

[Old Mod]

Spoke with Mark@Tilemaster about exterior leveller back around January I think. Under certain conditions they will/can advise Levelflex. Namely small areas or areas that aren't too open to the elements. Something to do with SLC being shrinkage compensated and having the potential to swell in wet environments. Bostik used to do a version of their Cempolaytex called Ultra which was guaranteed externally and over drives. Not seen a bag for years tho so maybe there was problems.

Well they still advertise it on their web site Rich, thank you!

Aaaarrgh Pro 50! For a little while I have to admit I thought this was the dogs proverbials. Flows lovely and drys almost course so the addy really grips, we even used it outdoors under an Original Style geometric now I think about it. However, it was also one the reasons the main contractor I was working for gave up Norcros for Tilesmaster. 3 Fails on 3 big floors. Twice it failed to set and the other just lifted in big sheets off the floor.

It was floorflex mate and no its only suitable for indoor use, found that out when I was doing that patio so ended up going with the Ardex 301 on that job..
