Just had our bathroom refurbished, and going to decorate ourselves the problem is the tiler has got smears of sealant on the bare plastered adjoining wall in the corners where the walls meet. I have read these corners should have just been grouted but there you go. What i would like to know is how should i tackle these corners as i know emulsion will not take to sealant. I do have a tin of Zinzzer B.I.N would a coat of this do the job before painting with the emulsion. ??
