Levelling concrete sub floor for laminate

Postby SWally » Sat Oct 03, 2009 5:47 pm

I'm going to fit B&Q tile-loc laminate in my kitchen. House built 1989, existing flooring is original thermoplastic tiles stuck onto concrete sub floor, still well stuck down so no probs there. Planning to use combi foam/dpc underlay, and sealant in board joints.
But I've measured uneveness of 3mm per 1m length. Is it OK to use self-levelling compound over textured thermoplastic tiles? I've never used this before, so which type is best for DIYer: some have latex, some don't. Also, any tips would be greatly appreciated. Thanks

If the tiles are the cushion floor type you will have to lift them, if they are the hard type the use SLFC with latex.

Thanks stoneyboy.

The tiles are the hard type, so I've bought the high performance latex SLC from Wickes as it has good user reviews. I'll prime the old tiles with diluted PVA first.
