I tried it twice one being thicker, it did not matter, they both crumbled ..... What did I do.... What so I need to do.... frustrated

@Aedan727, are you using Jennifer’s Mosaics Indoor Cement? Outdoor Cement or Plaster of Paris won't work for these indoor projects.

@Aedan727 It could be a water issue. To determine best ratio of cement to water, pour water into the mold until 7/8th full. Then measure the water poured into the mold, this is the amount of cement you should use. Divide the cement amount by 3 to determine the amount of water to use. So if a square mold take ¼ cup of water (3 tblspoons) use one tablespoon of water to the mix. If the mix appears dry, add one teaspoon water at a time until the mix resembles a pourable pancake batter.

@lldrummerboy1, This is a very unusual result, we would like to speak with you personally to diagnose the problem. Ask for Diana in Tech Support at 1-800-937-9593 x4.

Can not find mosaic coaster mold in craft stores by my house (michaels or JoAnns). Online w/ shipping is about $8.59 per mold. Do you know any other places that would sell this product? Shipping prices seem kind of unreasonable online.

Thanks

I've tried this twice and it has ended up crumbling. The first time I let it cool for approx. 5hrs and the second time 10hrs. Not sure what I am doing wrong, anyone else had this problem?
