It is possible to repair cracks in countertops made of composite materials such as Corian, and it's possible to fill a chip in a sink or a countertop with a two-part epoxy or an acrylic-based patch material.
Reglazing—also called refinishing or resurfacing—means that the existing high-gloss coating on your sink is stripped away, the surface prepared, and a new coating—also high-gloss—applied to the surface of the sink. The new coating is shiny, clean, and free of drips or brush marks, giving you a sink that looks like new.
If you have a small sink made from porcelain or stainless steel, you can expect to pay between $100 and $200 for refinishing services. However, if you have a larger sink made from marble or granite, refinishing costs can increase to $500 or more.
Sink Reglazing – Old Becomes New!
Vanity and sink reglazing, also called refinishing, resurfacing, or re-enameling is the process of giving a sink an immediate and dramatic transformation, restoring old and damaged surfaces in little time.
If the boards are cracked on the top and not at the bottom, you can simply turn it over. You should unscrew the board from the joists and turn the top to the bottom. After, you should screw the plastic composite board back to its place.
Knowing that cracks in your bathroom basin can lead to more serious problems, you should repair them as soon as you can. Many homeowners repair their sinks using DIY solutions like epoxy and DIY enamel kits, but there are more dangers involved.
Extremely hot water in a cold sink
In the case of less durable materials such as porcelain, fiberglass, wood and glass, these materials will eventually break down and erode if exposed to drastic temperature shifts over long periods of time. These usually will manifest as cracks, material stripping or warping.
Ceramic sink repair: Chips and cracks
Fear not: if the chip has only just occurred and you still have the broken piece at hand, you can a ceramic sink is quickly repaired with an epoxy adhesive. But even if you don't, or that piece is broken beyond repair, using an epoxy putty to fill the gap is just as simple.
A plumber should be able to repair this issue quickly. Cracked basin: A surface crack is something that can usually be repaired with some resurfacing. Larger cracks are a major problem, and simply taking some epoxy to prevent leaking is not a good idea.
Follow the manufacturer's instructions in mixing the porcelain filler for the repair work then using a matchstick or toothpick, to apply the filler to the cracked area. For a large crack, it is recommended that you apply the filler in layers. Allow the filler to dry, then sand it before applying the next layer.

Your sink's lifespan will depend a lot on its material. Stainless steel sinks last 15 to 30 years. Porcelain sinks last 25 to 30 years before they'll need to be refinished, after which they can last longer. Enamel steel sinks only last about 5 to 10 years if used frequently.
Composite repairs are needed due to either manufacturing defects or in-service defects. Once the defect is identified depending on the nature of the defect fill, bonded, bolted or injection repairs can be carried out.
Bonded composite repairs are most suited to repair of cracks in relatively thin-skin components, < 4 mm, with sufficient unobstructed surface area to obtain effective load transfer from the parent structure into the patch.
As with any filling material composites have a finite life‐span. Traditionally, replacement was the ideal approach to treat defective composite restorations, however, repairing composites offers an alternative more conservative approach to the tooth structure where restorations are partly still serviceable.
Refinishing a granite composite sink can be a bit of a labor-intensive process, but it is definitely possible to do it yourself if you have the right tools and materials.
