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 airtight, watertight seal that resists sagging, shrinking, chalking and cracking. It stays flexible throughout minor expansion and contraction and outlasts ordinary putty.
