JUMBO Letter Molds for resin and concrete // Shiny molds for resin casting // High quality molds
Listing is for a single letter mold. Please choose your desired letter(s) from the dropdown box!
Each finished letter is 6 in tall and 1.4 in deep. The width varies for each letter.
All molds are made with high quality platinum cure silicone that is suitable for casting resin or concrete. Molds with this material are made to last. However, molds will degrade over time/uses. There are many factors that determine how fast a mold degrades. Several things to take into consideration:
- Heat wears molds out. Using a torch on molds will damage them. Please stay away from using heat on molds!
- Slow curing resins have greater effects on molds.
- Mold releases extend molds’ life.
- Pouring thicker than the resin’s recommended depth may damage molds due to heat from the exothermic reaction.
- Bubbles formed on the surface of a mold (especially 3D molds) can scrape the molds during the demolding process. Please make sure that there are no bubbles on mold’s surface.
- Overstretching molds might cause permanent damage to them.
...and many more. Even though these are high quality molds, misusage can damage them or degrade them faster. While we can help troubleshoot and provide advice, we do not offer returns/exchanges on used items. Please refer to our Policy (located at the bottom of our website) for more information! If you see anything out of the norm with your molds upon receiving them, please reach out to us immediately to resolve any issues!
