« Part 23: Wiping on My Dye Mix Part 24 of Roll Around Tool Cabinet series Part 25: Sprayed on First Finish Coat »

I sprayed two coats of Zinsser’s clear shellac today in order to seal the dye I wiped on all surfaces of this cabinet last night.

Now I need to make a choice for the top coat finish. I have several cans of lacquer and polyurethane in my shop. Which should I use. This cabinet is a shop tool cabinet so durability is probably my biggest concern. I will study a couple of my finish books tonight.

QUESTION
What finish coat should I spray tomorrow? Lacquer? Or Polyurethane?

I also stacked the drawers that I also glued and clamped yesterday. I stacked them on top of each other in the cabinet bay where they will be mounted on metal slides. I measured the gap from the top drawer to the bottom of the face frame rail that crosses overtop of them. That gap is 3 1/2 inches. There are seven drawers and seven gaps to equally position. That calculates to 1/2 inch gap between each drawer. So I believe 1/2 inches will give me enough space to pass my fingers through in order to pull on the finger latch I routed into the top back of each drawer front. I did not want to cut semi-circle holes in this beautiful wood. I am trying to show off all of the sapele hardwood that I can in this project. I resaw cut 1/4 inch thick drawer fronts; actually they were probably 5/16” before hand planing the surfaces smooth.

The resawing was done on my bandsaw from the 8/4 sapele plank I found at MacBeaths Hardwood. It was like the perfect match for my cabinet. It was fate. I could not pass on its purchase. And, this plank ran like butter through my 1/2 inch bandsaw blade. I have temporarily forgotten the brand name of the blade but I bought it from Highland Woodworking. Someone on this site will know its brand name. Its now my favorite bandsaw blade.

Is your Zinsser’s clear shellac wax free? To my knowledge, the one in spray can has no wax, the one in a quart can contains wax.

^ the cans come in both waxed and wax-free varieties.

You can use most any finish over shellac. My favorite finish is just lacquer.
Lacquer is okay over shellac, just keep it out of direct sunlight until it cures.

I don’t care for poly or WB finishes, but some folks like them.

I used the Zinsser clear Shellac aerosol spray can. I know they have a dewaxed Shellac in a can that they call a seal coat. I believed their clear and amber canned Shellac both have wax.

On a website that I have linked here it says that the aerosol does not have wax. This product page says that this clear shellac can be used with lacquer and most other top coat finishes. However, I cannot find a Zinsser product sheet to detail exactly if the canned spray has wax or not.Thus, I am not certain. Even saying this I have heard others on the Internet claim that they have found no clear evidence that waxed Shellac has damaged their top coat finishes. However, I take that will a grain of salt. How much time did they let pass to test that theory?

Any suggestions?

It is sounding like lacquer maybe my best option.

Since I used a water based dye but sealed that with Shellac, would you consider this cabinet having a water base? And, would that be a reason for you not use polyurethane as its topcoat finish?

I am going to be using cans to spray either the lacquer or the polyurethane. I won’t be touching this cabinet with a brush or a cloth so I do not believe I have to worry about smearing the dye, or thinning the dye by pulling it around its surface.

My line up of finish…

If I use the MinWax polyurethane, I intend to spray first the clear gloss and afterwards the semi-gloss. Somewhere I read where that is the preferred order, if semi-gloss or satin is used. Does that sound right?

So much to learn… So much to remember…

No complaints from me. This is all good fun…

Pinto Deluxe… Gee, as a former Washingtonian I knew Camas sounded familiar but I did not realize it was along the Columbia River east of Vancouver and Portland. Why does it sound so familiar to me? Did DB Cooper jump out over this town? Or, was some of the money in his bag found along its riverbed? Or, was the skull of the earliest Indian or whatever he was found there? Something famous or noteworthy had to happen there. Lewis and Clark I am sure passed through there. Maybe those beautiful waterfalls are nearby. Or, is there a county in Washington that goes by Camas? No, that is in Idaho.

I bet the wind is always blowing along the Columbia River.. Does it even out in directions? Morning is one way and the evenings the winds blow in the opposite direction? Isn’t the Columbia used by those sail surfers?

At my age it becomes difficult to remember things.

I know. I am confusing Camas Washington with Kamas Utah. Probably both great places to live and do fun things in and roundabout.

Thank you for your comment. Would you stay away from using polyurethane finish after you have used water based dyes like TransTint on your project? Just trying to learn from guys with broader shoulders and more experience than I in woodworking. I make enough mistakes on my own which is one way to learn a lesson,..

I went looking for a reference on the Internet where someone questioned using polyurethane over waxed Shellac. I found it. I remember seeing this before. However, I try not to believe everything I read on the Internet. I can be suckered in on some things, but I tell you what: I am not falling for that Dell Support telephone call any longer. Fool me once. You won’t fool me twice. Support does not originate calls that way. I just wish that Dell would have told me directly that their database was hacked or stolen by an insider.

Are theses things called scuff pads? I am using the white pad to scuff the dye surface before spraying my finish coats. I will also use a scuff pad between coats, except for the last one.

I am probably doing this wrong. I don’t know. The little fibers are wedging into the grain fibers. It will take some work to rid them before spraying. Maybe a fine grit sandpaper would have been a better choice. I suspect the water based dye raised the grain to cause this situation.
