I have levelled my bathroom floor with 6mm layer of Level Pro. I didn't quite get it level in all places. I have got a bag of Level 15 so I can put a 0.5-1mm coat on top to get it nice and level. Do I need to prime the existing SLC with Sika 11W+ or will I get a good bond straight on top of the existing SLC?
Hi there Allan, you need to prime all substrates prior to installing levelling compounds (ie. the installed Sikafloor Level PRO). Alternatively, you can install Sikafloor Level Pro Finish 0-4mm skim coat which is self-priming. Hope this helps!
@@SikaNewZealand Thanks, I just saw the Level Pro Finish product after I bought the bag of Level 15. Is the Pro Finish pourable. The data sheet says apply with a trowel with pressure. I assume thats just for a skim coat? Re the 11W+ primer I have, would I dilute that 3 parts water to 1 part primer for the existing SLC? Thanks
@@allanpennington, yes you are correct on both points - Sikafloor Level PRO Finish is not flowable, it needs to be trowelled. And yes, the Sika Primer-11 W+ ratio is spot on. Good luck!
