Simple instructions for making a piece of mosaic art are to pick the desired material, select the foundation to apply them to, sketch a pattern on the foundation and apply the mosaic pieces to the foundation with mortar. The next step is to apply grout to the mosaic pattern and let it set and wipe it away from the surface.
Material pieces that are suitable for mosaics include glass, stones and seashells. When choosing a foundation, be sure that the base is strong enough to hold the mortar and grout. Beginners at mosaic art should choose a simple pattern to start out with. Sketch the pattern on the chosen foundation and use a hammer or glass cutting tool to break the mosaic material into pieces. Clean the pieces before using them.
Apply mixed mortar to the pattern on the foundation surface with a trowel or spatula. Press the material pieces into the mortar while it is still wet, or apply the mortar directly to the pieces before fixing them to the foundation. Let the mortar set for at least 24 hours and then clean any mortar that rose to the top.
Prepare a grout mixture and apply it to the mosaic with a spatula, filling the spaces between the pieces. Let the grout sit for about 20 minutes and then use a wet sponge to wipe it off the surface of the mosaic. The last step is to seal the piece with a varnish spray.
