coop floor: is this safe?

[crsandlin]

Hello all. just getting down with our first coop. Wanted to know if this product would be safe on the floor. Its black jack roof and foundation coating liquid asphalt coating. Had some laying around in garage. Noticed a couple people posted about black jack 57 they don't have that here. Any thoughts or opinions would be great. Was thinking of linoleum but over time thought it might deteriorate. Or should I just use some kilz sealer. thoughts and opinions thanks
