Once you have installed new laminate countertops, it is time to caulk them. Wilsonart has 100% siliconized acrylic caulk that is color matched to any of their laminates. No mixing, no color charts, just purchase the caulk that is the same name or number as the laminate you picked.
Wilsonart Color Matched Caulk is stain, mold, and mildew resistant, stays flexible and is water resistant.
Use painters tape, masking tape or any type of tape that doesn’t leave a residue to mask off an area to keep caulk over seam. Allow for approximately ¼” or less of caulking area on each side of the seam.
Caulks, especially silicone, work better at room temperature, so bring it inside the night before and let it warm up. It will bond better and smooth more easily.
Cut the tip off of the caulking tube at an angle, close to the tip. A smaller opening helps avoid overfilling the joint. Pierce the seal of the tube and slowly squeeze the tube while watching for the caulk to become visible at the end of the tube.
Apply caulk. Run a bead of caulk directly over the seam. By providing steady pressure to the caulk tube, move along the seam at a steady speed. Work on an area no more than 2 to 3 feet at a time. Smooth over the entire length of the applied bead of caulk in order to straighten it out and further force the caulk into enough surface contact to establish good adhesion. This is called “Tooling”. You can use your dampened finger or various tools like a spoon, a shaped piece of wood, or a foam paint brush. Tool the caulk until you are satisfied with the appearance. Keep rags or damp paper towels handy to clean up any problem areas right away. It is much more difficult to clean up dried caulk or caulk that starts to skin over. Repeat this process until entire countertop edge is sealed.
Tip: Caulk is made not to flow, so tooling is critical to force it into good contact with the substrate.
