A boomerang counter is made from laminate, so this is your core material. If you are planning on keeping the boomerang pattern in your kitchen but need a fresh surface, laminate is the only option for your new counters. Because laminates are plastic shells, they can be manufactured in nearly any color combination, which can make it easier to match the pattern with other surfaces.
If you have an old boomerang countertop and are wondering what to cover it with to renew the surface while still keeping the original countertop material, there are coatings and paints available for laminate materials. Choose a paint designed for laminate surfaces and made with additives that protect the surface from molds. This can help cover up the boomerang pattern, or potentially customize the pattern with a unique layered design.
Laminate is only a plastic coating, so it is easy to remove. If you want to cover your boomerang counter with a different material, such as ceramic tiles or wood block, you need to remove the old layer of laminate first. Carefully pry the sheets off the counters and chip away any remaining adhesive. For tile counters, a new layer of backerboard can help prepare the surface and avoid any leveling problems.
If you have a boomerang counter in place and are wondering how to finish it, consider covering the edges with metal. Stainless steel or chrome borders along a boomerang pattern can work well, and give the counter a retro appearance which may fit in very well with your style choices.
