Pinholes in Jarrah Top
I am new to the forum (and a lot of woodworking things as well) so I apologise in advance if this querry has been raised before.
I have recently had the jarrah benchtop of a long (6m) cabinet refurbished by an "expert". The top was finished with nine sprayed coats of a two pack polyurethane (supposedly the best imported stuff). My problem is that the surface has the typical 'orange peel' finish which I am unhappy with. I have experimented on a small section by sanding back with 1200 grit paper and completing with EEE-Ultra Shine. This has resulted in a beautifully smooth surface (whereas it felt rough to the touch before) but the surface now has lots of what I can only describe as pinholes. I'm guessing that this is because my sanding hasn't gone deep enough but I'm worried about going any further lest I completely stuff it up. Any suggestions gratefully received.

Firstly you cant stuff it up the looser who finished it did that for you.
Before I give you any ideas what is the benchtop used for ? Is it in a "wet" area?

It is the top of a cabinet in the lounge room (no wetness).

it is possable that the "pin holes" are actually tiny air pockets created as the polyurethane dried. sanding it back may not do you any good.
you could also be able to sand back and then apply a light coat of 2 pack again and hope that you get a better finish.
as a last desparate measure you could be faced with stripping the whole lot back and starting again. sorry to be the bearer of bad news.I try and do new things twice.. the first time to see if I can do it.. the second time to see if I like it

Take it back to who did it and get them to sand and refinish. :eek:
From a proffessional POV if what your describing is accurate it ain't good enough. At the very least you should get them to look at it and get there opinion. If they say its good enough get a second opinion from another pro if they say its good enough, it probably is. But if not you have avenues you can follow.
Orange peel really is a result of really poor product & application knowledge.
DON'T play with it too much before getting it looked at!
Oh & 9 coats ???? :confused:

I would do as Shane suggests and ask the finisher for my money back if still not happy. Then sand and do an Oil finish yourself.
