How to Glue Corian
It is not always easy to find the right product to glue Corian. Corian is basically made of acrylic with polymer. This material is used a lot for counter tops and vanities for its beauty and durability. Epoxy glue should be used to make it stick together. Then it is advised to use a color matching silicone to bound the counter tops with the cabinets and the back wall.
Preparing the Corian
Professionals use denatured alcohol to clean the mating edges before applying the glue. This is to make sure the edges will get a good grip together. Then, the epoxy glue should be applied on both surfaces with a caulking gun. It is important not to wipe off the excess epoxy glue. Instead, let it dry for the right period of time and sand it off once it's done.
Hiding the Seams
Once the epoxy glue has cured, the excess should be sanded with a power sander using very fine sandpaper. The best way to hide the seams is to find a waterproof silicone that matches the main color of the counter top and to apply it right on the seam. The excess should be wiped off with a sponge to make the seam almost invisible.
The same silicone can be used to bound the counter top to the cabinets under it and the back wall, once the back splash is installed.
