Ideal for use with all acrylics, oils and other painting mediaThickerstronger canvas:We use 13 oz Triple Primed canvas-  thicker, stronger and more durable than most of our competitors.Triple Primed:All canvas is coated with 3 layers of gesso, making it ready to paint on and smoothing the surface for medium-smooth texture.Rust Free:Every staple we use is galvanized, eliminating staple corrosion. Perfect Angles:We use machinist accuracy in creating perfect 90 degree angles while assembling all our stretcher bars frames.No Rubber or Vinyl Splines:Our canvases DO NOT use splines thus eliminating the risk of the spline popping out–which produces a loose canvas which will ultimately need re-stretching.Kiln Dried Stretcher Bars + Braces:Make the frame extra strong and stable- guaranteed not to warp.Any canvas over 30″ is braced to add extra strength.Sizes 36 X 48 and up Also includes corner braces.FREE SHIPPING ONLY AVAILABLE TO THE 48 CONTIGUOUS STATES!
