Hardbord is the perfect substrate for those who prefer to create their own grounds and unique textures. Hardbord is a 1/8" thick tempered wood panel that is prepared without the traditional oil tempering process. This provides more strength and permanence than when using untempered or conventional hardboard. Hardbord accepts grounds for oils, acrylics, egg tempera, encaustic and gold leaf, with no preparation required and it will not warp, crack or bend. The cradled version of Hardbord features 3/4" and 2" supports that are glued flush with the back edge of the panel. The cradle provides extra support while giving the panel depth and dimension, making it ready to hang on the wall. The birch plywood cradles can be left unfinished or treated easily with wood stain, gesso or paint.
