I purchased two Swanstone solid surface vanity tops for my double-bowl sink. I trimmed them to site side-by-side and planned to use white silicone caulk between them to fill any very small gaps. They looked fine going in but the caulk sunk some after it dried and so I am thinking I need to take one out and fill the gap with something else that will have the following properties:
- Easy to clean
- Same or similar color as my tops
- Will bond to solid surface
I have considered epoxy of some sort, but I'd like to know if there is anything that is commonly used to this effect. I have seen granite tops lined up with little noticeable seam so I think it should be possible. Of course, I should have picked a darker color to hide the seam better but... live and learn I guess.
UPDATE: I received a response from Swanstone:
Hi, Corian can be chemically bonded but Swanstone cannot. We do a mechanical bond and then fill seams with an acrylic glue. These products are only available to certified swanstone fabricators. If you would like information on that, give me your location and I can tell you who to get in touch with.
I already have a mechanical fastening system in place, not pictured are three 1/4"x20 bolts in the front, back, and middle of the sink spanning the vertical supports of the two halves, which happen to butt against each other.
Addendum: Good info in general re: swanstone fabrication: http://www.jlconline.com/countertops/working-with-thin-solid-surfacing_1.aspx
Update: I followed Jack's advice and used glacier white SeamIt brand solid surface adhesive (2 part epoxy). The results are not bad, the only downside is that the adhesive itself has a different sheen than the swanstone so I think I'll try to rough it up later to cut down on reflections off of the adhesive line. The finished product is pictured below.
