...What to do with my SLC?
I have some Davco Dampfast waterproofer. Now, I've been reading the instructions about application and have a couple of questions about SLC.
I have used Lanko 133 Pro Level on the floor (only about 4mm deep) over my concrete slab, and it was poured a couple of days ago, so it is dry, with no signs of surface moisture. However, what is it considered to be? The Dampfast instructions detail what to do with new concrete slab, new render etc, but what about SLC? Is it considered to have a "wood float finish"? Or maybe a "steel trowel or power float finish"? Do I need to mechanically abrade it before applying the Dampfast, or not? The Lanko 133 data sheet doesn't seem to mention how it should be treated in this case.
Thanks in advance for any advice (except "get a pro in", don't have the money, but do have free waterproofing membrane!)
But seriously, any help would be appreciated.
