Spray Finish

I started finishing the other day. Out in the driveway. I used the spray can of shellac on the edges and irregular spots. Chewed through the whole can in nothing flat. The slab seemed to almost soak it up. I will use a brush to add some layers to it now that the little cracks and crevices are somewhat covered up.

The edges darkened up nicely; however, when I do the flats, they will darken too. So I am not sure of the final look.

Glass

My neighbor suggested that I put a glass top on the slab and make it a table. I hadn't thought of glass before. If I were to put it on standoffs (maybe marbles or rubber feet) it would both protect the slab and provide a nice level surface. I called a couple places for glass prices. For a 1/4-inch piece, 42-inch-diameter round, the price varied from $160 to $350, and that's more than I want to spend. Perhaps I should hit 2nd hand stores. I bet I could get a whole table with glass cheaper than that.. and just repurpose the glass.

Ready to Shellac

I finished sanding today. 220 grit. Then I borrowed my son's electric air compressor and blew off all of the dust. As it turns out, I also blew off a bunch of loose stuff from the sides that I didn't get picked off earlier. Next step is to shellac the sides and irregular areas using the spray. I am nervous about overspray and will try to protect the flatter surfaces that I will do with a brush. I used some mineral spirits on it the other day to wipe off dust. Someone told me that the mineral spirits give a preview of the finished look before they evaporate. It was quite dark. I guess I will find out soon. I decided not to use the blow torch on the edges. I think they will be fine as they are.

As for uses... I am leaning toward hanging it over my fireplace.

Which Finish?



I talked to Jeff Watson at Woodcraft about finishes. He had some great information. We decided that shellace would be the best option. It doesn't yellow, is easy to repair, and is attractive to boot. I bought a can of spray for the edges--they are so rough that I could never brush them. But the spray isn't very good for the finish on the flat areas. It could end up with an orange peel unless you spray with a sprayer. Two options are available for hand-applying the finish to the flats: (1) brush, and (2) I think he called it patting. The patting option sounded a bit complicated, so I am going to brush it. Shellac is a natural resin mixed with alcohol.. and dries very fast. I may practice on something else first. He also sold me some synthetic steel wool to rough it up a bit after the first coat and to knock the gloss down on the final coat if I choose to do that. Jeff thought that the plant idea was great (I am not convinced). He also said that if I go with a table, black wrought iron legs would be his choice. See my earlier post with options. All in all, a good visit... Thanks for the help, Jeff.
