We have tiled stairs and applied the black strips of gripping material. Has worked great for us too. Link to product on Amazon Mexico

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.

It's rainy season and the world is often wet. We have several places that are almost like painted steps that we use to access other parts of our world. We learned early on to not step on the painted surfaces when they were wet. One dog did too, but the other, not. She often steps on them, falls, slides, no injuries yet, but we want to avoid that. These three spots are concrete.

Basic internet search, Bob Villa said, " 4 parts paint, one part sand," then went on to say, pour some paint into a container, add a handful of sand, and paint.

Did it this morning, used the paint that was supposed to match. It took only a few minutes to do the three areas. Tonight??? OMG It looks just like it did before, but if you step on it with bare feet (or dog feet) it is heavily textured.

SUCCESS!! And a very safe thing that most of us here can use!!
