Surface Preparation:
• When re-glazing, remove from sash (i) all old glazing compound, (ii) any glazier points and/or spring clips,
(iii) glass, and (iv) any back bedding. Glass should be free from any residual glazing compound and back
bedding prior to reinstallation.
• All surfaces must be clean, dry, and free of frost or any substance that would compromise adhesion of the
glazing material (e.g., wax, oil, grease, rust inhibitors, silicone residue, etc.).
• For metal windows, sash corners must be sealed. All sashes must be safely installed and adjusted prior to
glazing and sufficiently rigid to permit normal operation without excessive bending or flexing. Adjustment of
freshly glazed sash will disrupt the adhesive bond of the glazing material to the glass and sash.
• For wood sash applications, prime sash with an oil-based primer only and allow primer to dry.
Product Application:
NOTE: Do not apply DAP® ‘33’® Glazing when air or sash temperatures are below -4°C or above 32°C. Do not
apply during damp or rainy weather or if rain is forecasted within 24 hours of application.
1. Mix entire contents of container by hand (by kneading or rolling glazing in gloved hands) until
uniform. Do not add any type of oil, pigment, thinners, solvents or additives to the glazing compound.
2. Bring compound to room temperature (20-22°C) prior to use. If necessary, place glazing in a gloved hand to
warm and soften.
3. DAP ‘33’ Glazing must be applied to backstop of wood or metal sash to provide back bedding where glass is
to be set. Minimum thickness of back bedding is 1/8” throughout. Only DAP ‘33’ Glazing may be used for back
bedding. There should be no metal frame-to-glass or wood frame-to-glass contact.
4. For back bedding of metal sash, use spacer shims at quarter points to maintain 1/8″ minimum bedding
thickness throughout.
5. Press glass firmly into place. If glass size is over 609 mm (24″) in horizontal dimension, use setting blocks at
quarter points on bottom rail. For clear glass, maintain 6 mm (1/4″) minimum contact area between glass and
compound throughout. For heat absorbing glass, 9.5 mm (3/8″) minimum contact area is required throughout.
6. Install glazier’s points (wood window frames) or spring clips (metal window frames) at quarter points of
windowpane to hold glass. Space the points/clips no more than 457 mm (18″) apart for exterior glazed sash. For
interior glazed sash, space them no more than 12″ apart. Points/clips are necessary to hold the glass in place.
The glazing compound should not be expected to perform this function.
7. Press only DAP ‘33’ Glazing onto sash and against glass, being careful to fill height and width of L-shaped
recess completely.
8. Smooth glazing to an angle that sheds water. There should be no gaps, spaces or indentations. Then shape
corners to a rounded finish only.
9. Remove excess glazing with mineral spirits before it sets.
10. If excess glazing needs to be removed after setting, such material must be cut, scraped away or otherwise
mechanically removed.
NOTE: Do not use DAP ‘33’ Glazing on plastic windowpanes, porcelainized steel insulating panels, insulated
glass units with an organic seal, stained or leaded glass, any windowpane over 48 inches in any run direction,
any metal sash with rabbets over 31.75 mm (1¼”) wide, composite or composition panels, channel glazing or
on any surfaces not prepared as set forth below.
