Both Wedi (pronounced “weedy”) and Feathercore are lightweight and customizable backer boards that are made as tile underlayments but have many uses in mosaics. Wedi is from Germany and Feathercore is from Asia. Both have a styrofoam center that is reinforced with fiberglass mesh and a polymer mortar coating making them very lightweight and weatherproof. They are sold in both 1/2" and 1/4" thickness. Suitable for indoor and outdoor projects, they can also easily be cut to any shape or size that is desired. To cut Wedi or Feathercore, you simply need a box cutter or saw. Straight cutting only requires the box cutter while more intricate shapes and designs can be done with a saw.

These backer boards provide a great, lightweight base for your outdoor projects. Other surfaces are either unsuitable for outdoors or are quite heavy to begin with before adding tiles and grout to them. Wedi and FeatherCore solve both these problems.
