Re: Z poxy as a gap filler

Post by Zen »

I have put on 4 coats of Zpoxy as a Pore filler on the back of my indian rosewood parlor so that should be ok ? I still see streaks when it dries out and they are caused by the old credit card I used as a spreader. Is that normal to have lines and streaks . I know I can sand them out and level everything with a fine paper but will sanding take off the most of what I have just put in ? Or is that the general idea .Any tips on how to proceed from here ?

thanks

Zpoxy should handle the pores fine. Sand with 180 and see what you have . When I use Zpoxy I wear vinyl gloves and rub it into the pores. One issue I have seen with Zpozy is that if you don't clear it from the surface you may have a signature of it under the finish. This is a filler not a sealer .Sand to level and don't go finer than 220 grit..
Wipe down with naphtha after sanding , you should be able to see what you missed.

With epoxy in general and Z-poxy in particular you either need to leave a thin coat of it on the entire surface after it is level sanded or sand back to expose most of the wood and only leave the epoxy inside of the pores. John's advice on sanding is spot on, make it too slick and the finish wont stick. If the sanding is spotty and there are patches of bare wood and epoxy your finish will look blotchy because of it. Some woods are very sensitive to this and others a little more forgiving.

looks pretty good. A few coats of sealer will now tell the story. Look close to the wood and you will see if this came out right. It is not uncommon to see a little orange peel effect on the surface , but you will still have to level sand after the build coat. Then do some finish coats for the final sand and buff out.

Thanks John, I had half a bottle of sanding sealer left over from last time and decided to use that. Unfortunately its been so long since I did any finishing that I have forgotten the process and will need to read up on it again . But, in the meantime I spread on some of the aforementioned sanding sealer I had found, and immediately it started to drag and appeared to be curing as i spread it on so i ended up with a mess. Its Rustins sanding sealer but its about 6 -8 months old so just wondering if that could be the problem. Is it supposed to be brushed on or spread with a squeegee? Should i have diluted it perhaps ? Sorry for the silly questions as i should know better by now but the memory is not what it usta be .
Thanks John

some sealers will start drying very fast.

As a general rule, sealers should be applied by spray or brush.....maybe a roller in a pinch.
