Slippery steps and things

Here is another tip that I learned when I built a sailboat.

To texture a wooden surface, put down a layer of your chosen finishing product, like Varathane or varnish.

While it is wet, sprinkle coarsely ground walnut shells rather than sand onto the tacky finish as the textirizer. When it cures put on additional layers of finishing,product, alternating with ground shells if desired.

When it comes time to sand the surface for refinishing, the sandpaper will be able to sand off the walnut shells, whereas sand as the texturizer would chew up the sandpaper. The coarsely ground walnut shells are sold commercially for this purpose.
