Carol Lombardo asked 9 years ago

We have oil based painted kitchen area and want to put new drywall skip onto it. Some say sand off until shinny is gone, some say tsp only – it etches enough, and some say sand lightly and prime then texture and prime again.

Please help me. I need it.

I am unfamiliar with the term "drywall skip." Based on the remainder of your question I will surmise your are asking about using sheetrock mud as a texture. if this is the case, I would recommend you take all possible precautions. Reasoning is due to the difficulties of repairing any texture which does not adhere.

With that thought, I would suggest washing with a strong solution of TSP, or sanding enough to remove the shine. Follow this with a "barrier" type primer. The primer must perform all the adhesion for the texture as the mud will not adhere to a slick and finished surface.

Again, I will always recommend a primer over sheetrock mud. With out the primer, you will have noticeable differences in sheen levels for the finish job.
