Remove the sink and any other fixtures. Clean and dry the existing laminate. Sand it with your power sander and 100-grit sandpaper, just enough to take the shine off the surface. Thoroughly clean the dust off.
Measure each span of the countertop (top, front edges, backsplash). Use your jigsaw to cut a piece of laminate for each span, making the laminate overhang any open edges of the span by an inch. Spread contact cement with brush throughout the back of each piece, and on the whole surface of the countertop. Let the contact cement set according to the instructions. The cement on either surface should be dry to the touch.
Carefully set the main front edge piece of laminate in place. Don't allow the contact cement on the back of the laminate to touch the cement on the countertop until you're sure it's positioned correctly, because they will bond instantly. Use the rolling pin to roll the piece on as you secure it to prevent air bubbles. Run your router along the top and bottom edges to trim off the excess of the laminate and even it with the countertop.
Lay dowel rods on the top of the countertop front to back, about a foot apart, across the whole surface. Lay the top laminate piece on the dowel rods, cement-side down (it won't stick to the rods). Position the piece correctly. Pull out a rod from the middle and press the laminate down to the surface so it makes contact with cement-covered countertop and sticks. Use your rolling pin to flatten and press the laminate in either direction toward the edges, putting out the dowel rods as you go. When it's all down, run your router around the edges to trim off the overhand. Trim out the sink hole in the same manner.
Laminate the top edge of the backsplash in the same manner as you did the front edge. Laminate the forward-facing vertical span of the backsplash last. When all the laminate is down, re-install the sink.
