Summarize the following:
Hold a measuring tape up along the wall to determine how much space you have available. If your old worktop is still in place, it can serve as a useful estimate. When building around a corner, plan on connecting 2 slabs or dividing a slab into 2 pieces with a diagonal cut.  For non-square worktops, measure out the space you have available, then carefully measure out how you’ll make your cuts. Wood worktops expand and contract a lot. When using them, leave 5 mm (0.20 in) between the wood and the wall. Leave 30 mm (1.2 in) between the wood and a freestanding oven. Trace the dimensions you measured directly onto the worktop slabs. No matter what material you choose for your worktops, you can order them pre-cut. If you got pre-cut material, you will only need to do this if the worktops are too big or need to be divided. Worktop material can be wood, laminate, granite, or another material. Place some masking tape over each cutting line. Dark lines don’t show up well on dark worktops, and you’ll also be wearing safety goggles while the saw kicks up sawdust, so the yellow helps you stay on track. The masking tape can be removed when you finish the cuts. Before sawing worktop pieces, take safety precautions. Put on goggles to shield your eyes from chipped material. Face masks offer extra protection, so they may be worth the cost. The type of saw you need depends on the material you’re cutting. A jigsaw can give you precise cuts on a variety of material. If you’re cutting stone, such as marble, use a diamond-tipped circular saw. Carefully cut off the excess material until you’ve formed the worktops you need. The cuts you make will be rougher than any factory-made cuts. Plan to hide your cuts against the wall or under a joining strip, if possible. Both of these features need plenty of space. To get the most accurate estimate possible, move the worktop to the location where you’ll install it. Locate your water line for the sink and your gas or electrical lines for the cooktop or hob, as that’s where you’ll need to cut the holes. Never place these features on the joints between 2 worktop pieces. An easy way to do this is to flip them over and lay them on the worktop’s surface. Masking tape and a marker pen are perfect for creating the guiding lines. Before cutting, move all the lines inward by 5 to 10 mm (0.20 to 0.39 in). This is because the edges of these features hang over the worktop so they don’t fall through. Some sinks and cooktops come with templates you can trace on the worktop. Put on your safety gear again and fire up the same saw you used before. Carefully cut out both holes. Remember that a cut that’s too small can always be fixed, but one that’s too big can’t. Pick up a fine file or sandpaper at the home improvement store. Smooth over both the utility holes and the outer edges of the worktop. When they feel level instead of sharp, the worktops are ready to be installed.
Measure the size the worktop will be. Draw the measurements on the worktops. Tape over the measurements for visibility while cutting. Put on goggles and a face mask. Cut the worktop to shape. Find the spots where you’ll put the sink and cooktop. Trace the sink and cooktop on the worktop’s surface. Cut out the traced areas with a jigsaw. File down the rough edges of the worktop.
