Self Leveling against framing - how to handle edge?

I will be pouring self-leveling concrete into a 13' x 16' room that has framing installed over the original concrete floor. The instructions say "Create a minimum of 1/8" to 1/4" wide gap where Level Set 200 self leveling underlayment abuts walls, columns, and fixtures by installing a self-sticking foam weather stripping tape or damp sand".

Do I need to install the weather stripping where the SLU will abut the bottom of the framing?

Just cut and staple strips of cardboard against the framing. It will collapse if expansion is needed. Cheap and easy.

BTW, pretty big area to self level, what depth are you looking at and what eventual flooring are you going to install. If tile, tile needs a flat surface, not necessarily a level surface. SLC is not cheap and doesn't go near as far as you would like it to go.
