Artist Jill Gatwood uses the following method to make water-resistant foam-core mosaic backers for exterior mosaics, such as the Pet Memorial Name Plaques she does for clients who need something that is lighter weight and easier to ship than stone or solid concrete. The method wraps the foam in three or four successive layers of […]
Outdoor mosaics must be made on concrete or stone or masonry, but that doesn’t mean you have to pour a concrete slab or do some other form of heavy construction. Flagstones (flat paving stones) and concrete stepping stones are readily available at building material stores and lawn and garden centers. The flagstones are great if […]
Artist Risa Puno recently completed her interactive mosaic sculpture Common Ground for Rufus King Park in Jamaica Queens, NYC, and the project is a great example for discussing materials and methods for mosaic table tops. No Plywood Backers Outdoors Plywood is never an acceptable backer for outdoor mosaic table tops. Humidity in outdoor air can […]
Recently I received an email from an art teacher whose school mosaic project was an outdoor mosaic where each child would create a mosaic on an 8 inch x 8 inch brick paver (paving stone), and then the mosaic pavers would be arranged together in a crazy quilt design similar to what artist Victor Kobayashi […]
In the last section of one of my previous posts, Custom Shapes For Mosaic Backers, I showed some pictures and instructions for how I used 3/4-inch expanded steel to make a backer for an outdoor mosaic. The expanded metal was welded together in 3 plies, some mounting bolts were welded to this, and then the […]
Thinset Mortar The first thing you need to know about outdoor and wet mosaic (pool, fountain, shower) is that thinset mortar is used instead of glue. Thinset mortar is a type of concrete with polymers added for tensile strength and enhanced adhesive properties. It contains sand and portland cement just like standard concrete and comes […]
The Four Seasons mosaic by Marc Chagall in Chicago was originally installed outdoors in the 1970s but has since had a glass canopy installed over the top to protect it from the elements. Part of the reason for the canopy is Chicago’s harsh freezing weather, which is hard on all mosaics, but another reason for […]
I recommend that schools wanting to make a mosaic mural for their school consider “crazy quilt” displays that are assembled from individual mosaic projects all on the same size backer, say anywhere from 6×6 inches or 12×12 inches. This allows each student a real art experience (making their own design) instead of just being a […]
At the end of 2019 Mosaic Art Supply was e-mailed by a local homeowner about repairing a stone mosaic that was being displayed outdoors. The design of the mosaic is a smaller-scale interpretation of the “Tree of Life” mosaic found in the bath of Hisham’s Palace in eastern Palestine. The palace dates to the 700s […]
Marine plywood cannot be used as a mosaic backer for outdoor and wet mosaic. Yes, marine plywood can withstand the outdoors and wet days for many years, but it is completely unacceptable as a mosaic backer because it swells and contracts with changes in humidity in the outside air. That amount of swelling and contracting […]
