How a slab is glazed
For glazing, the panel should be lightly sanded with a 120 grit so that the glaze can penetrate well. For wood that has already been treated, start with coarser grains. The glaze should be applied quickly with a brush in the direction of the grain of the wood. After the glaze has hardened after the manufacturer's specified drying time, it usually feels very rough. In any case, the surface should be reground with a 180 or 240 grit. If several layers of color are desired, the process can be repeated accordingly. It is possible to oil or wax the glazed surface again as a finish.
