🧪 Application / Usage

This stone repair filler is excellent for crack repair and creating near-invisible joints of filling.

2–3% hardener mix (approx. a pea-size amount of hardener to a golf-ball size of resin).
Apply with a spreader; remove excess before curing.
Once cured, the material can be sanded, ground, or polished to match the stone’s original luster.
