Mastering Mud with Kelley Knickerbocker

Curious about or frustrated with mortar* as a mosaic adhesive? Then you’re in the right place. Mosaic Arts Online presents Kelley Knickerbocker and her latest course "Mastering Mud." Kelley has been setting every imaginable type of tessera directly into mortar to create mosaic for nearly two decades, and in this online course she walks you through her favorite mortar-wrangling techniques for super strong bonding, clean working (yes, it can be done!), and a great finished look. In addition, you’ll discover that setting into mortar eliminates the need for grout in most instances and makes working with wildly varied heights of materials a breeze.

Step by step, from scratch coat to finishing coat, Kelley guides you through the correct consistency for different applications of mortar, mixing with water vs a polymer admix, tinting with dry or wet tints, maneuvering the stuff around on the substrate, and three different methods of setting tesserae into place (mortar bed, backbuttering, and the baggie method). Along the way, of course, she demystifies all kinds of terms like slaking, pot life, load rate, and read-through.

Along with all the technical and structural information about mortar, Kelley hopes to plant the notion in your creative psyche that mortar can be as vital a visual design element as your tesserae and your substrate (what?!). By showing a wealth of images, and building a mostly-mortar mosaic from start to finish, you’ll come away with a new appreciation – and new inspiration - of how mortar can be a gorgeous, strong addition to your mosaic designs.

*The terms thinset, cement mortar, mortar, and tile adhesive will be defined and then used interchangeably in this course
