There are times, especially on large LifeCasting projects where you just run out of time and the alginate begins to set before you're done.
Algi-Bond is our solution to this dilemma.
Add 2 teaspoons to a quart of warm water and stir until the powder dissolves. Spray the Algi-Bond solution onto the leading edge of your alginate. Wait 2 minutes and a new batch of alginate will stick to the old one. Special solution softens the alginate on a molecular level so the new alginate can grab hold of the old alginate.
This small 50 gram bag of powder makes up to 2 gallons of solution.
