From a 1/4 x 4 board, cut pieces 3-1/2 inches long for each coaster you plan to make. Smooth each coaster base with 120-grit sandpaper.
Apply at least one coat of paint (Lincoln Cottage Black shown) to each coaster base and let dry overnight.
From the sheet of mosaic tile, remove the individual tiles from the mesh backing. Then use a putty knife or utility knife to remove any loose adhesive, mesh strands, or flaking stone from the back.
Select four tiles of equal thickness and the smoothest available surface for each coaster. Group them on a flat surface to check that they’ll provide even support for a cup or glass when assembled.
Place a dab of general-purpose construction adhesive on the center bottom of a tile and press it against the coaster base at one corner. Repeat for the remaining three tiles to cover the base. Flip the coaster upside down and check that the base is centered over the four tiles. Allow to dry overnight before using.
