sealant

Hi guys , I'm roughcasting an external wall but I need to apply some kind of waterproofer/Sealant before I roughcast the external wall. Any tips on the best product to use would be greatly appreciated. Cheers, Robbie.

Hi I'm not a plasterer. I've had my flat replastered and I really like the pink mottled plaster look, reminds me of holidays in Italy, and I want to leave it as it is. But I'm aware that it marks and any grease, even from hands, will blemish it. So it needs sealing, ideally so it can be washed...
