CRL DAP 33 White Glazing Compound Quart - Window Glazing Putty

• Ready-to-use glazing compound for wood and metal sash
• Smooth, creamy consistency that resists sagging, shrinking, chalking, and cracking
• Must be painted after curing for a durable finish

CRL DAP® '33'® Glazing Compound (SKU: 33QTW) is a smooth, flexible glazing putty formulated for face-glazing wood and metal window frames. It bonds well to both glass and sash to form a dependable air- and watertight seal, providing long-lasting performance on interior and exterior sash applications.

SURFACE PREPARATION & APPLICATION

• Mix entire contents until completely uniform; separation can occur—rolling into coils warms and softens the compound for easier handling.
• Surfaces must be clean, dry, and frost-free. When re-glazing, remove all old putty and bedding.
• Unprimed or bare wood sash must be primed with an oil-based primer and allowed to dry before glazing.
• Apply a thin back-bedding layer (about 1/8" thick) of DAP® ‘33’® Glazing to the sash backstop before setting the glass.
• For metal sash, use spacer shims at quarter points to maintain a minimum 1/8" bedding thickness—ensure no direct metal or wood-to-glass contact.
• Smooth putty with a putty knife to a water-shedding angle.
• Allow putty to skin over and attain a firm set before painting—typical dry time is one to two weeks depending on temperature and humidity.
• For best results, finish with a high-quality oil-based paint; if using latex, prime first with an oil-based primer.

Product Warning:

• Do not thin glazing compound.
• Do not apply when air or sash temperatures are below 40ºF (4ºC).
• Not for use on plastic window panes, insulating glass units with an organic seal, panes over 48" (1.22 m) in length, or metal sash with rabbets over 1-1/4" (32 mm) wide.
• Not recommended for stained or leaded glass projects.
• Clean tools immediately after use with mineral spirits.
