Description
Stone Seam 5020 hardener is the clear curing component supplied for compatible Chem-Set Stone Seam resin systems. This 16 oz bottle gives countertop and stone shops a larger refill format for regular seaming work, color matching, and repair preparation. It is a component rather than a stand-alone adhesive, so pair it only with the Stone Seam resin and process specified for the job.
Where Stone Seam 5020 Hardener Fits
Use this refill when a shop already works with the Chem-Set Stone Seam family and needs additional hardener on hand for clear, pigmented, flowing, or knife-grade seam formulations that call for the 5020 component. The bottle format supports controlled bench dispensing and keeps the curing component separate until the resin is prepared for application.
Application and Handling
- Confirm that the selected Stone Seam resin calls for 5020 hardener before mixing.
- Measure the resin and hardener according to the current Stone Seam instructions for that resin format.
- Use clean, dry tools to avoid transferring cured material or pigment into the bottle.
- Blend the batch thoroughly before adding color pigment or placing adhesive in the seam.
- Prepare only the amount that can be placed during the available working period.
- Close the bottle after dispensing and keep the cap and neck free of mixed material.
