I’m using Deft Clear Wood Finish for the first time. Am working with mesquite in which I’ve used the Inlace Inlay product to add a turquoise accent which has cured for a couple of days. After applying the third coat of Deft Lacquer (waiting at least 30 minutes between coats) I’m suddenly getting black areas developing over the piece, noticeable mainly on the inlay and don’t seem to see any on the mesquite. Has anyone had this experience with Deft Lacquer? Funny thing is it seems to only be in the final layer of lacquer. I first scraped an area off, resprayed again, only to have it reappear. Appreciate any tips/advice you might have.

Been using Deft lacquer for years … never had any issues with it, however I have never done anything in mesquite. Any chance of getting some pictures of the affected piece?

I have sprayed mesquite with Deft lacquer and no problems. Maybe the lacquer is dissolving/reacting with the epoxy in the inlay?

Originally my thinking was that there might be a reaction with the inlay epoxy, but upon further inspection I’m picking up some spotting over the wood as well. And it’s only as deep as the top coat. These are solid black freckle sized spots that don’t appear for about 20 minutes or so after application. Could it be that I’m applying the coats too heavily causing some kind of reaction with the underlying lacquer? Thanks for your input on this.

They could be bugs. For some reason they dive into lacquer. I have experienced lacquer darkening in areas where I used blue tape. Pulled out the instructions from the center and the first statement was, “do not use on lacquer”.

Maybe. When you apply second/third/etc. coats the solvent in lacquer softens the the surface causing it to ‘melt in’. The solvent evaporates, leaving a hard finish which can be re-coated to build a thicker film. If you are putting on super heavy coats I suppose it is possible that some sort of chemical reaction in the solvent could cause what you are seeing.

Are you spraying, brushing? Pictures of the problem would help. I’ve never had any problems with Deft.

Were you spraying with a gun or a rattle can?

Spray some on a sheet of white paper to see if it’s coming from the can. Go from there.

I’m using a rattle can and I’ve taken it back to bare wood. Having applied the coating in thin_layers I’m not seeing the problem again so that must be it. Previously I sprayed enough to give it a wet look, but not so much where I had runs or orange peel showing up. I guess the trick is to keep it thin and apply more than three layers for the final coat. That’s the only thing I can figure.
Thanks for all the responses!

I must say, it can’t be it as I have applied this heavily and it just takes longer to dry; no black spots.
