Blue Grit on kitchen walls under wall units

No you shouldn't see no blue grit

No, it shouldn't. The Blue Grit is there to provide a key for the skim coat, so the wall(s) should have been skimmed and (potentially) painted prior to the cabinets being fitted. If the Blue Grit (pva) and the plastering has been applied after the units had been fitted, then you should have no visible signs of it. If it is on the edges (i.e. by the worktop or under the wall cabinets) then a light sand should do the trick along with a bit of sealant/filler/etc. If however, you are having tiles on that wall, then the Blue Grit will be covered by them. I hope I have covered some scenarios here, but if it doesn't look right to you, then it would be best to ask the plasterer or the one that applied the Blue Grit and explain the matter to them. All the best Romeo

I have to agree, blue grit should have no reason to be visible, and doing things in the right order would dictate putting units on wall after preparing, skimming and painting them.

Blur gritt should not be visible at all as a Finnish. It is used as a key coat for back grounds with less suction and then skimmed
