Would anyone know if mixing 'Unibond Super-PVA Adhesive & Sealer' with
Emulsion paint is any better at covering wall & ceiling cracks, than
just using the 'Unibond Super-PVA Adhesive & Sealer' on its own?

Someone told me they heard something about it on the radio, but they
didn't catch the full thing.

Would anyone know anything about this? Thank you!
