drywall over lip of shower surround

Hi All

Have installed a Sterling bath/shower with surrounds. Next step is to drywall, which will partially extend over the lip, leaving quarter inch gap to be caulked. Question - How do I/Do I need to 'seal' the edge that extends over the lip (potential wet area if caulk fails/shrinks)- or should I buy about twice what I need so I can use the side edges all the way around?

TIA

I don't understand buy twice as much of what?

You would caulk the whole perimeter where the surround meets the drywall.

I meant that if I should only use the 'bull nose' edges, then I will have to buy twice as much. Whereas if there is a good sealing method for the cut edge of greenboard then I can do that and save a sheet. I will caulk where the board meets the surround regardless.

It seems to me that sooner or later caulk will shrink/fail, so if that's all I do with a cut edge, moisture will get to the interior of the greenboard, then I have a mess.

Greenboard, blueboard, regular sheetrock...really doesn't matter. Now if this is the newer water/mold resistant that has no paper..thats a bit different...but they will all wick water from either a cut or uncut edge. The new stuff just has no paper for the mold to feed on.

Caulk it well, paint it well. Shouldn't be much real water splashing on it. Just a little mist that will evaporate if you keep the fan running as recommended.

.... and if the gap is too big or ragged, you can flat tape the edge. Caulk when you'e done with the j/c.
