  • 【Double-Layer Structure】- The mold is made of plastic(outer shell), silicone (inner tank). The outer hard plastic shell has good texture and is not easy to be broken. You don't need to worry about the mold being unable to withstand the weight of the concrete dumping or the uneven force, thus getting an irregular flower pot.
  • 【How Can We Better Demould ?】- We strongly recommend that before filling cement or gypsum, please apply a layer of mineral oil or any vegetable type of oil or fine powder will work between the silica gel and the plastic holder, which can help us more easily demold after the cement is solidified.
  • 【How to Make The Pot Stronger ?】- We'd better add some coarse sand and crushed stone into the cement to make it a solid whole, just like the concrete used for building houses. In this way, place the flower tray in a cool and ventilated place and wait for natural drying. During drying, pay attention to the curing condition. If the temperature is too high, sprinkle water properly to avoid weakening the curing effect caused by too fast drying.
  • 【DIY Octagonal Shape Flowerpot】- Finished product size: 6.38 x 6.38 x 3.07 inches/ 16.2 x 16.2 x 7.8 cm, you could prepare some concrete or gypsum materials, and make flowerpots according to the proportion, add any mix various colors according to your preferences, just enjoy the DIY process.
  • 【Flowerpot & Candle Jar Making】 - Planter silicone mold can be applied to make flower pots with concrete, clay, and plaster, and allow you to grow your small plants, succulents, cactus, flowers and some small vegetables. It can also be used to make candle holders.
