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...

Step on can to close it

Step on a Can to Close It

Here’s a tip that you will thank me for if you aren’t already doing it. When you want to secure the lid on a paint, stain or finish can, step on it rather than hammer it closed. Using your body weight to close the can has two advantages. First, you don’t have to have...

These are the three Zinsser Bulls Eye shellacs that no longer provide a date of packaging or a stated shelf life

And now the company has stopped telling users even...

Boiled linseed oil and tung oil

Comparing Linseed Oil & Tung Oil

The two commonly available pure oil finishes that can be used on furniture and woodwork with decent results because they cure – that is, turn from a liquid to a soft solid – are linseed oil and tung oil. There are important differences between these two oils. Raw linseed oil cures much too slowly...

Using Solvents to Date Furniture

Editors note: Bob Flexner’s blog will move to the Flexner on Finishing Blog at the end of April. You can find it here. A few years ago I was called to a long-time client’s house to look at a problem on their newly purchased eighteenth-century Chippendale dining set. I was excited. How often do I...

Try cleaning first, with water, soap and water or mineral spirits.

Rejuvenating Old Finishes

Editors note: Bob Flexner’s blog will move to the Flexner on Finishing Blog at the end of April. You can find it here. Just because a finish is old and deteriorated, you don’t necessarily have to strip it and apply a new finish. You may be able to rejuvenate the finish so it looks...

Smart Coatings

It seems like everything is becoming smart these days: smart phones, smart watches, smart cars, smart drugs. There are even smart coatings (paints and finishes). I’ve blogged about one already, a coating that uses nanotechnology to create an air barrier that causes liquids such as pee to bounce off walls and cover the perpetrator’s...
