Wash off NMP residue with denatured alcohol

Wash off NMP Residue

Here’s a caution when stripping paint or finish from furniture or woodwork. Most of the newer “safer” strippers are sold in plastic containers and contain the solvent n-methyl pyrrolidone (NMP) as the active ingredient. This solvent is relatively expensive, so manufacturers often mix in other solvents to reduce the cost. But it’s the NMP...

Finish Choices for a Wood Deck

It’s that time of year and you may be thinking about how to take care of your wood deck. Here’s the easy way to approach it, at least for decks made of rot-resistant woods such as redwood, cedar, pressure-treated, or one of several jungle woods including ipe. If you’re OK with the wood turning...

Here's the black scrape early in the process of removing it.

Removing a Black Scrape on a Car

While visiting my son and daughter-in-law, I noticed that she had a pretty ugly black scrape on the side of her car. She had gotten it when she backed out of a tight parking space and rubbed up against the plastic back bumper on a truck. I decided to win points by removing it....

Finish for Wooden Pens

I got a question about finishes for turned wooden pens. Full disclosure: I’ve never turned a pen. Nor have I turned a bowl. My experience with the lathe has been turning parts for furniture I’m restoring. But I know a bit about finishes, so I think I can answer the question. The pen turner...

Deck Coatings that Fail

More on Smart Coatings

Smart coatings fascinate me. In an earlier post I told you about a paint that uses nanotechnology to cause pee to bounce off walls back onto the shoes of the perp. In another post I told you about a coating that self-heals when exposed to heat or UV light. Here are a few more smart coatings...

Crackle Lacquer

Crackle Lacquer

A friend called me the other day with a question. He was matching a crackle-lacquer finish from the 1980s and wanted to know how this finish is made and how to apply it. Crackle lacquer is lacquer with so much solid material, usually silica, added that there isn’t enough binder (lacquer) remaining to glue...

Here's what a professional spray booth looks like

Spray Booth for a Small Shop

In the December, 2001 issue of Popular Woodworking (issue # 125) I wrote about how to construct a simple but safe home spray booth. This article was reproduced in my book, “Flexner on Finishing.” But what if you have more space, do a lot of finishing and would like to have something more like...

Update on Sherwin-Williams buying Valspar

In my March 22 posting I passed on the report that Sherwin-Williams is buying Valspar for $11 billion creating one huge supplier of many brands of finishing products we use. But not so fast. Now the Federal Trade Commission is beginning to investigate on antitrust grounds. Unfortunately, at least in my opinion, this administration...
