Will it be a one time use mold? As in, will the mold break apart after one pour of lead? The melting point of lead is 621 degrees Fahrenheit.

Answer: 
No, use construction adhesive, silicone and hot melt glue. I use a mix of all three. The hot melt holds while the adhesive sets up. Make sure the surfaces are super clean...

Answer: 
Plaster of Paris is not recommended for use in wet application areas, as it has low water resistance. The most commonly used product for your type of project would be a latex modified thinset mortar (as used for tile setting).

Answer: 
DAP® Plaster of Paris is primarily recommended for general wall and ceiling repair. It can also be used for mold making, casting sculpted figures, and hobby and craft applications. The more appropriate product for mold making and casting projects is DAP® Plaster of Paris Hobby & Craft, however, it is only available in a 4.4 lb. package.

25 lb. White Plaster of Paris Dry Mix is rated 4.3 out of 5 by 19.
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 5 out of 5 by from I have used your plaster of paris for years! I use your plaster in all my sculptures. My technique I learned from an art professor I had at Long Beach State University. I use a 2 to 3 times plaster to water without mixing. I then hand apply the plaster to a wire armater. It sets very hard yet it can easily be finished with files and sand paper. I then paint 6 coates of bronze tone paints and seal with varithane spray.

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.
