What is a Sealer for Stained Glass Projects?
A sealer for stained glass projects is a protective coating applied to stained glass pieces to enhance their longevity and appearance. Stained glass is often exposed to various environmental elements, making it essential to protect it from damage, dirt, and moisture.
Key functions of sealers for stained glass include:
