A rapid 30 minute set time plaster compound used to patch and repair large or small holes in interior plaster when a fast setting product is desired. An excellent base coat for large holes. The ultra smooth, hard, white finish makes the product ideal for casting or modeling by hobbyists, artists, and pattern makers.
- Size: 4.4 Lbs.
- Great for casting molds.
- Can be used for patching applications.
- Ideal for mold making, casting sculptured figures and hobby and craft items.
Surface Preparation & Application:
- 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.
- Add DAP Plaster of Paris for Hobby and Craft to clear cold water in a clean container mixing 2 parts powder to one part water. Stir to a smooth consistency. Do not mix more material than can be used in 15-20 minutes. Discard any material that has begun to harden.
- Pour the mold in 4 or more parts. Fill ¼ of the mold up at a time and tap the mold on a tabletop to release air. Continue to fill mold ¼ at a time tapping as you go.
- After 1 hour remove the dried Plaster of Paris from the mold. Allow the cast to dry 1-3 hours depending on size.
- When dry, apply shellac to piece. Allow shellac to dry 2 hours before painting.
- Surface must be clean and free of wallpaper, loose paint, loose plaster, wax, dust, and dirt.
- Undercut edges of existing plaster so patch anchors around opening.
- Lightly dampen with water the area to be patched.
- Add Plaster or Paris to clean water in a clean container mixing 2 parts powder to 1 part cold water. Stir to a smooth consistency. Do not mix more material than can be used in 30-35 minutes.
- Apply the Plaster of Paris with a clean putty knife or trowel filling around edges. Remove excess materials so that plaster is level and flush with the surface being patched.
- 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.
For Best Results:
- Use cold water when mixing.
- Sand as needed before decorating. Wet sanding is recommended to avoid creating dust.
- Always use a good quality oil or latex-base paint for a professional finish.
- For repairs requiring a longer work time (over 30 minutes), use DAP Plaster Wall Patch.
