• Sets hard in 20 to 30 minutes for quick repairs
• Professional quality, for repairs in plaster walls and ceilings
• Easy to sand and paint
• Non-shrinking
• Smooth, bubble-free formula


• Use cold water (40°F to 50°F) when mixing.
• Sand as needed before decorating. Wet sanding is recommended to avoid creating dust.
• Always use a good quality oil or latex-based paint for a professional finish.
• For repairs requiring a longer work time (over 6-10 minutes), use DAP Plaster Wall Patch.
DO NOT attempt to make a cast enclosing any part of the body using this material. Failure to follow these
instructions may cause severe burns that may require surgical removal of affected tissues


1. Surface must be clean and free of wallpaper, loose paint, loose plaster and all foreign material.
2. Undercut edges of existing plaster so patch anchors around opening.
3. Lightly dampen with water the area to be patched.
4. Add DAP Plaster of Paris to clean water in a clean container mixing (by volume) 2 parts powder to 1-part cold
water (40°F to 50°F). Stir to a smooth consistency. Do not mix more material than can be used in 6-
10 minutes. Discard any material that has begun to harden.
5. Apply the DAP Plaster of Paris with a clean putty knife or trowel filling around edges. Remove excess
material so that plaster is level and flush with the surface being patched.
6. For large, deep openings apply a base layer and allow it to dry. When the base layer is dry, wet the
surface and apply the finish layer to patch. When thoroughly dry, sand smooth. Make sure the plaster
is completely dry and hard before painting.

1. The mold should be clean and free of loose material. For most uses, wetting the inside of the mold
prior to pouring is sufficient. However, when a super-smooth surface is desired on your finished
piece, a coat of mold release is recommended instead of water. A suggested mold release is a
mixture of mineral spirits and petroleum jelly mixed to a watery consistency and applied with a brush
to the inside of the mold.
2. Wet inside of mold for easy removal after drying.
3. Fill mold one quarter at a time, tapping on tabletop to release air after each fill.
4. After 1 hour remove the dried Plaster of Paris from the mold. Allow the cast to dry 1 to 3 hours
depending on size.
5. Allow 24 hours to dry.
