Baumit top coat over PRB base

[SJ2022]

Hello,

I've got a few bags of PRB basecoat left but no PRB crepisix top coat. I do however have some Baumit top coat and was wondering if there was any potential issues with mixing brands on basecoat/ top coat. I know there will be no warranty etc but it's a tiny gable less that 2x2m and doesn't seem worth buying a full tub of PRB top coat.

Thanks
James
