No, you don't want to put Kilz down. The adhesive for the LaSalle Bristol RV Roof Replacement Kit w/ XTRM Membrane item # 344270KIT35 won't stick to the primer. It needs the bare wood. The item # 344270KIT35 install kit comes with everything you need to install the membrane.

If you need anything else don't hesitate to reach out in the comments below.

@Denise Yes, you can use LaSalle Bristol ABS Solvent Cement - Black - 1/2 Pint item # 3447530889 for that extra section of membrane.
