Technology Comparison

Both are formulated for crystal clarity on white marble, but the underlying chemistry differs — epoxy typically offers a stronger, more colour-stable long-term bond, while Tenax's solid mastic format is documented for controlled, vertical-friendly application with UV stability for outdoor use.
