Self leveling cement contacting wood sole plates

I am going to be using Floor Self-leveling cement on a small 10x10ft section of our concrete basement floor (never used the stuff before). One corner of the floor is slightly off level with much of the rest of the floor (a little less than half an inch perhaps), I expect the self-leveler to flow towards this section to level off with the surrounding area. Two of the rooms sides have wood 2x4s laid flat that are the sole plates for existing partition walls, one of them runs into the corner with the low section that then meets with the concrete foundation wall which makes up the other two sides of the room.
My question is, what should I do, if anything, in regards to the self-leveler coming in contact with the wood sole plate of the partition walls? The low section is less than half an inch low, so there is potential for the cement to come in contact with the wood sole plate for an equal depth in the very corner. The rest of the sole plates may have minor contact with the cement along there full lengths as I spread a very thin coat across the entire floor to give it a smooth surface. Should I be concerned about the self-leveling cement making contact with the wood sole plates? Is there anything I should do first to minimize this? Thanks in advance.

I'm not the final answer on this but here are a few thoughts. First I have seen many garage floors poured after the framing and the cement butts the sole plate. If it is a concern then you could staple a plastic sheet against the plate.
I used SLC and found self leveling meant that after you pushed it around with a squeege, used a float and finished with a hand trowel it was level. I had expected it to flow as the name says and it doesn't happen. I spent some time on the phone with the tech department of the manufacturer who forwarned that it was more considered self leveling after being squeegeed to very small depths. Jump to the tile forum and find a post by John Bridges and click the link to his board where you'll find many experienced proffesionals for this topic. Pick up a heavy duty drill, a mud mixer and 5 gallon buckets for mixing.
