Topic tags/keywords: question finishing

I have built a humidor for my step-son and I wanted to put a high gloss finish on it. When I opened my can of gloss poly, I realized that I had put stain in it to tint it a while back….I did’t want any color on the humidor, just clear, so I opted for my satin poly. I am finishing up the 4th coat today and was wondering if there was anything I can do on top of this to get some more sheen? Will paste wax or any kind of wax help? I also remember reading in a FWW a guy used an automotive mirror glaze polish on a mahogany top to get a good sheen. Any thoughts on this Thanks in advance

Eric

The finer the grit of the sanding would also put a sheen on it. 2000, 3000 and 4,000 would bring out a gloss.

Like Karson said, wetsanding with really really fine sandpaper makes a finish shine or glow depending on where you stop.

if you are going to wetsand you need to have something to sand. you need at least 7 coats and you need to give it about 2 weeks after the last coat so it can cure before you sand it.

Why not put on one or two coats of high gloss over the satin? It should brighten it up.

John is correct. With poly the sheen of last application will determine the sheen of the finish. But if you are after a mirror finish then you will need to go with the higher grits and/or polishing compound.

Yeah, wet sanding is out due to time, but is a good idea. John, I was thinking of putting some gloss on top, but since it’s tinted, I wasn’t sure if it would add to much dark color, which is what I don’t want. I don’t even have enough time to try it on test pieces, so I’m not sure. I might just end up leaving it, or maybe just try the gloss on the bottom to see what it looks like. Thanks guys for all your feedback

The smother the finish surface the higher the reflective property it will have. So build your top coats to a thickness that allows you remove all the peaks and valleys by sanding and still have finish left to polish. Using paste wood filler to fill the pores of open grain woods dramatically speeds up the process of obtaining a smooth surface without 10 coats of finish. I have a video tutorial about it on my site.

View: Paste Wood Filling

Light sanding between coats with 320 free cut paper makes it faster to do the final sanding at the end. Just don’t cut through. Also let the finish fully cure before the final sanding and polishing. If you don’t you run the risk of the finish shrinking further after all your hard work and blemishes reappearing.

For a glass like finish, after fine sanding, you can polish out the scratches with compounds and/or use a buffer. Then apply a glaze to remove the swirl marks, then wax.

What prevents you from purchasing a new can of “gloss”?
