FREE SHIPPING Exotherm 4.25 x 25 x 3 Coaster No Seal HDPE Epoxy Reusable Form

  • Sale
  • Regular price $90.00


No Seal Coaster Form, inside measurements are 4 1/2” x 25” to allow for trimming and finishes

These forms are designed with 5-degree sides to allow cured pours to be tapped out once completed.
Fabricated using 3/8” HDPE (High Density Poly Ethylene), the sides are bent up and corners welded to make a right seal.
There is a small bead of welded plastic around the inside perimeter of the form. Simply tap the sides inside of the form and turn over and tap the bottom to release the cured project, start new project right away.


These forms have welded sides that don’t require any sealant or tuck tape.
Your project is easily removed by tapping the sides and back with a mallet. Once removed, you can start another immediately

Please use rubber mallet to tap your cured project out of the form by gently hitting the inside of the sides and flipping over and hitting the bottom. Using excessive force inside on the sides and using a metal hammer will void any warranty.


Please read carefully instructions on how to mix and pour your Epoxy.


Epoxy that does not cure properly will make it impossible to remove your project.


Epoxy that over heats during the curing process will twist and crack the Form, sometimes adhering to the form. Again making it very difficult to remove your project for the form.

Mold release is not needed but will not hurt if used 

Wood not included
