CRL DAP® '33'® Glazing Compound is smooth and flexible, and comes ready-to-use for face glazing wood and metal window frames. Its adhesion to both glass and sash is excellent, forming a dependable air and watertight seal that resists sagging, shrinking, chalking, and cracking. *Surfaces should be clean, dry, and free of frost. When re-glazing, remove all old putty and bedding.
SURFACE PREPARATION & APPLICATION
Separation occurs in glazing Putty; mix entire contents of container until completely uniformed before the application. If necessary, roll into coils to warm and soften.

* Apply a thin layer of DAP® ‘33'® Glazing (about 1/8" thick) to backstop of sash to provide back-bedding where glass is to be set.
* For metal sash, use spacer shims at quarter points to maintain 1/8" minimum bedding thickness. There should be no metal or wood to glass contact.
*Smooth glazing to an angle that sheets water with a putty knife.
*Typical dry time before painting is one to two weeks, depending on temperature and humidity.
*Putty must be painted after it has skinned over and attained a firm set. Typical dry time before painting is one to two weeks, depending on temperature and humidity.
