  • Premium Safe Natural Materials: OSBANG casting plaster powder is made of premium natural materials. This Oorless plaster powder can give you a safe and worry-free handmade experience
  • Fast Curing Plaster Powder: The plaster powder curing time is about 2 hours, faster than many epoxy resin. 25-30 minutes demold time is recommended, for not break those tiny details of your art works. Please note that do not demold until fully cured
  • Beginners Friendly Casting Powder: The faster curing mixing ratio plaster powder : water = 10:3(By Weight). Mix well, pour into molds and wait 10min to 2h curing(determined by ratio, and the size and depth of the mold), very friendly for beginners
  • TIPS: Different plaster powder : water ratio curing time 10:3 > 3:1 > 2:1 ,you can freely adjust the ratio! The curing plaster artwork is porous and non-water-tight, sealed with sealers like wax sealer, acrylic sealer or varnish is recommended

Mixes well, no bubbles, good product
Size: 1KG / 35 OZ
Mixed well, no clumps, no hubbles. Easy to measure and pour. I can’t really comment on drying time because I leave mine overnight, but by the next day it’s solid and easy to demold. I’d recommend. Good value for the price.

checks all the boxes
Size: 3KG / 105 OZ
This works soooo much better than Plaster of Paris. There are NO bubbles, you can de-mold within 20 min and it is fully cured in a couple hours. It is definitely worth the price difference. Would 100 percent recommend for anyone doing plaster figures to paint.

Great!!
Size: 1KG / 35 OZ
I actually love this product! Once I learned the correct ratio it was very easy to use. Still some learning curves to go over -However, it was very easy to learn. I made this bowl/tray for my sister and it is so STURDY! My only complaint is the amount it takes to fill a large mold. Obviously will be getting this again and getting a larger container this time! ... show more

I’ve purchased this product several times already and it has worked great every time. The texture is smooth, easy to mix, and sets really nicely without too many bubbles. I use it for different craft projects and molds, and the results always look clean and professional. The quality has been consistent with every order, which is why I keep buying it. Definitely recommend if you want a reliable casting powder for detailed creations. ... show more
