DAP® 33® glazing is a ready-to-use glazing compound that may be used for face glazing wood or metal sash. Its knife-grade quality allows for smooth, easy application. DAP® 33® glazing sticks tight to glass and sash for an air-tight, water-tight seal that resists sagging, shrinking, chalking and cracking. It stays flexible throughout minor expansion and contraction and outlasts ordinary putty.
