Plastering & Rendering

Gloopy plaster sealant and brush marks on new plaster wall. Should I sand down?

I recently had my hallway and living room replastered. I bought a special dulux paint sealant- similar to the pva glue mix but extreme,y expensive. We began to roll on to the wall but the plaster was absorbing it so quickly we opted to use brushes. ( I think we were going over are to much as the coverage was difficult) However I now have gloopy brush marks on the wall and also lumps of gloop from where we rollered it. We decided to use the traditional 50/50water and paint mix for living room luckily. But what should I do for the hallway? Should I sand down? Then seal with 75% paint and 25% water? The sealant says do not sand down afterwards but I presume that's because I might then expose bare plaster so may need to lightly reseal. But not sure how a watery mix will be over the pva type sealant. I contacted dulux and they told me to use special polycele plaster paint for a smooth surface but I think is excessive as we've just had it replastered. Any advice?
