With the new grill at the ready, Doug measures before he cuts a rough opening (figure E) in the island from the top and front cement boards (tip: a wet saw keeps dust down when cutting cement board). He reinforces the cut edges with 2 x 4s so the island will be able to support the weight of the grill (figure F).The gas line will drop into the empty space below the new opening and will connect to the propane tank, allowing access to the connection from the back side of the grill.
Tiling and grouting
The tiling and grouting may be the most time-consuming part of the project, but they can also be the most rewarding. You can select the color and tile that will look best in your yard. The choices are endless, from tumbled marble to flashy granite. Using the same color and material as the countertops in the kitchen makes for a nice transition. Larger tile means less time tiling and grouting; smaller tile adds more interest.
Doug mixes a fast-drying thin-set powder with water until he achieves a peanut-butter-like consistency (figure G). If it's too thick, it's hard too spread; too thin and it forms bubbles.
Again, keeping things level is key. As Doug lays the tile, he pushes and pulls as required to keep the top even.
Once the tile is laid, grout is a great cover-up for mistakes or blemishes in the tile. Grout is basically a mixture of sand, some sort of hardener such as cement, and a colorant. Doug mixes the grout in a bucket and he applies it to crevices to fill pits and blend the colors. After your complete grouting, and before it gets too hard (and too difficult to work with), it's important to take a bucket of clean water and a sponge to gently pick up stray grout (figure H).
Finishing touch: Two to three days after the tile work is finished, Doug applies a sealant to the stone.
