Can I make a mold with plaster and pour melted lead into the mold?

Can this be used in making plaster castings

This product doesn't say Plaster of Paris. I use plaster of paris in my mold making for plaster crafts. Can this be used in place of regular plaster of paris?

Can it be put in refrigerator

Asked by: ZIGGY
Best to wrap in plastic to keep the unused POP dry. Mixed and hardened POP would be fine in the refrig.

This plaster of paris product sets up too fast to be a useful product for repairing plaster surfaces larger than 6" by 6". I found that you have less than 4 minutes before this stuff goes from soup to rock. If you mix up more than about a half cup, you will throw most of it away. I am still looking for a product that can be used to repair plaster over wood lath walls in a 100+ year old house. This isn't it.

Rated 5 out of 5 by from Works great on interior walls for repairing cracks and holes. Soak plaster in water according to ... Works great on interior walls for repairing cracks and holes. Soak plaster in water according to directions, then mix with joint compound (1:1); result is hybrid plaster that sticks to pretty much anything, very smooth and doesn't get raggedy when troweled thin, dries very fast (and hard), and best of all, will not shrink or crack when fully dry. Working time is about 10-12 minutes; USG Plaster of Paris does not set as fast, 15-20m, on average, I've experimented with both.

Rated 5 out of 5 by from Excellent for use in Mold Making for Lost Wax Casting I always use DAP Plaster of Paris for my molds since it seems to mix very well with sand in both 1:1 ratio for higher detail AND 1:2 ratio for a stronger hold. I love that it sets quickly and dries white. USG dries off-white/ cream eggshell and that's extremely annoying after using DAP. DAP also seems to be a better quality plaster than USG. USG crumbles even well beyond it's complete curing time. DAP does not. I've never used USG for molds as it is weak and I never plan on using anything other than DAP Plaster of Paris for my casting and mold making needs. It's an absolutely perfect fit for Aluminum and Bronze casting.

Rated 1 out of 5 by from Beware: wrong product shown!! The product shown in the photo (DAP Plaster Wall Patch) is a completely different animal from the one listed in the title (White Plaster of Paris Dry Mix) and actually stocked on my Home Depot's shelves. The former is DAP product # 10304; the latter is DAP 10312. I just spent 2 hrs on a wild goose chase trying to buy the wall patch & finding only the pure plaster of Paris. The wall patch has a higher lime content; it has a longer working time and a thicker consistency. The straight plaster of Paris only has a working time of 6-10 min. It is fine for cracks or small holes but not for larger areas.

Rated 3 out of 5 by from Not for plaster wall repairs Do not try to use this product to patch holes in plaster walls, or to add a smooth top coat to plaster walls. This product sets up too quickly - at best 20 - 30 minutes, and if it's old can set up much quicker. DAP makes a product called "Plaster Wall Patch" that sets up in 2 hours, and according to the manufacturer can have a working time of up to 90 minutes. You need that extra working time to be able to smooth out the patch or top skim coat. This product is best for craft projects or plaster molds. Since I can not seem to find Plaster Wall Patch at Home Depot I went to DAP's web site and got a list of stores I can get it from.

Rated 5 out of 5 by from vinegar A little vinegar added will delay the drying time. Giving you more time to work it. -Old School

Rated 5 out of 5 by from Excellent for making molds and detailed casts I use Plaster of Paris to make molds and small casts of detailed objects. It sets up quickly and is very strong. Larger molds can be reinforced with cut-up fiberglass cloth. Antique ceiling details and old plaster lamps can also be repaired (when clean and dry) with new Plaster of Paris, but working time is very short. Very large plaster pieces should be reinforced with something stronger, like metal rods. When set-up and completely dry, Plaster of Paris accepts all paint, varnish, and other surface treatments I have used. Note: Even in a desert climate, it can take up to a week for larger plaster pieces to dry. It also does not sand as easily as drywall mud. Plaster of Paris sands better with a rasp. Not recommended to texture overall wall surfaces. Drywall mud is better for that purpose.
