If you are re-treating waxed canvas or applying wax to cotton canvas for the first time, the Otter Wax Smoothing Tool is a high-quality tool to have on hand. Made of premium birch wood, this tool fits snugly in your hand for ease of use. Once your wax has been applied to the canvas, you can use the flat side of this tool to help penetrate the wax deeper into the fabric, creating a better seal. The pointed edges of this tool aid in removing excess wax should it accumulate in the seams of your canvas.
