Thanks for your help 🙂
The smooth PEI sheet.
I take it you have received the textured sheet (Which personally I would only use for PETG and TPU).
PRUSA do a smooth spring steel PEI sheet or look on Amazon and type Prusa Mk3 then search for a spring steel sheet with PEI adhesive sheet
But I cannot comment on the quality of these, sometimes you may get a good one sometimes not.
thanks for your feedback.
i have the prusa PEI sheet witch is really good but produce a mat finishing, but i prefer a glossy finishing like with a glass. because my first layers are put on front of walls 🙂
i am selling 3D printed art that are hanged on walls 🙂
i really love my prusa printer. thanks to the prusa tea for their work !
Would it not be just as easy to spray the finished face with gloss lacquer as not all filament is capable of a glossy finish especially PLA.
For glossy finishes you really want to be using PETG and at the higher end of it's temperature, which can cause stringing, also with no cooling.

I have seen some very nice prints (on other printers) with mirror-smooth first layers printed on glass. The surface is almost mirror like. They are absolutely beautiful, but that result is not easy:
- You need a perfect flat piece of glass. This is not as easy as it sounds and you won't know the glass is smooth enough until you try it.
- No prep can be used on the glass. The finest coating will distort the finish.
- Your first layer calibration has to be perfect. Too high and there will be small gaps between extrusions. Too low and they'll be squished and distorted.
- You have to get it off the glass without damaging the finish.
So while I won't say what you're trying to do is impossible, I can say it's not easy. You can get close on a Prusa with the smooth PEI surface, but it will work best with a new PEI sheet (no sanding, very little prep) and it won't be as shiny. As @chocki suggests, some post-processing is probably much easier and less error-prone. Alternately, check out what people have done with textured print surfaces.
