Metal Reverse Concrete Casting Letters

Basic instructions for using metal Reverse Lettering

Temporarily fasten reverse lettering and numbers so that they can be removed and reused to cast different information; use caulking material.
General Purpose 100% Silicone CLEAR (use with a caulking gun).
You may use other clear caulking silicone products which are sold in small tubes.

After you fasten the letters and numbers in the mold, let the caulk set up for an hour or as recommended. After it sets up, trim the excess material from around lettering.

Then apply a release agent very carefully so you don't move the letters.
You're now ready to pour the concrete.

Be sure to clean the mold and lettering thoroughly with soap and water after each use. Mild dish washing liquid works well.
