Wood & Stone Akabond 621 KG Part A — Clear Knife-Grade Epoxy Resin for Stone (1/2 Gallon)
Akabond 621 KG Part A is the resin half of Wood & Stone's two-component, clear knife-grade epoxy adhesive for natural stone. Formulated for light-colored marble, quartzite, and granite, its translucent, color-stable gel body resists sagging on vertical joints and leaves nearly invisible seams. Combine with Akabond 621 KG Part B hardener (F015531) at a 2:1 ratio by volume to bond, laminate, fill, and consolidate stone on both interior and exterior projects.
