Bestone Solid Surface Crack Repair Techniques

Look into the reason of why the solid surface has cracked to begin with, before trying to fix it. It would most likely that cracks again because the original stress or origin reasons for the crack still exist. As an example, the lack of proper support on the cabinetry, or an uneven plain between supports.

Cracks on solid surface can't just be filled, it will only crack again. A good start is drilling a very small hole at each end of the crack; this will stop the crack from spreading. About a ¼” drill must works well. After to make the crack stopper drills, use a router and a straight cutter to trimming out all the thickness through the whole trajectory from the starting to the end crack stopper drills.

Professionals use a custom made template for using in an advanced technique which is called “pie-slice” patch, when crack is spread in a wide area or goes through in an irregular trajectory. This technique needs a portion of solid surface material which is usually got from the sinks and stove cut-outs, in order to avoid color matching issues. The template is used to perform a cut-out surrounding the cracked area to taking it out and an identical piece is obtained with the same shape template from scrap material. This results in a “jigsaw” piece which fits perfectly on the performed cut-out.
This technique works well for countertops, wall panels and must of the solid surface jobs installed in a plain application. However, sinks, bowls or shower pans with cracks are quite different case to be repaired.
Anyhow, the goal is to recover the material strength on the piece and the crack must be removed. If the job is a challenge because the surface to be repaired is not easy to access, it is always a good option to use a high speed hand tool such as a Dremel® rotary tool. Always go through the thickness to achieve a good seaming.

Clean perfectly the repair area with denaturalized alcohol or acetone. The seaming area must be free of dust and grease.
Use the seaming compound following the manufacturer directions and allows curing enough time until the seaming is hard at touch and does not feel sticky.

When the seam is hard enough, grinding off the excess using sand paper and an orbital sander machine.
Begin by lightly buffing down the scratches with fine grit sandpaper. Increase grit as needed.
