The resining plant, which is from Breton S.p.A., was purchased by Cometti in August of 2002. The epoxy resin fills in the pores of the slab and results in a vitreous material wherein the granite is completely smooth. All of the steps in the resining process are automated, from the loading of the slabs through the final delivery to the processing line.
First the slabs are dried in an oven, and then machinery automatically applies the resin along with a catalyst. For materials that need special attention, the resin can be applied by hand. A vacuum chamber drives the resin deeper into the stone, and better reinforces the material, and the slabs go into a second oven for quick hardening. These ovens can dry/harden up to 40 slabs at one time.
