Now Follow How to install undermount sink with a laminate countertop


Step I: Cut the opening

Turn the countertop upside down on the area you work on. Use the tape measure to delineate or mark out the exact area of the countertop you want to install your new sink.

Draw on the countertop the exact shape or boundary against which you will subsequently install the sink. Use a pencil to do so. Check a second time to be sure that the dimensions and the shapes are both fine.

PS: Some sinks will often come along with their own templates against which you can mark out these shapes and dimensions. In case that exists, utilize it rather than drawing your own unique shapes. It will make your work easier.

Step II: Cut the hole

Using your drill and the 3/8-inch bit, drill a hole at the corner of the countertop. Cut another hole around the opening using the saber saw as closely as you possibly can. In case you lack a saber saw, a hand saw may do for the straight lines whereas the keyhole saw may do for the corners. Once you are through with this, proceed to mark out and drill the holes to be used for the mounting screws.

Step III: Mount the sink

Start out by cleaning the area around the opening where you will subsequently install the sink. Use the denatured alcohol and the clean piece of cloth. Be sure to impact the cut itself, the area around the bottom of the hole, as well as the top of the sink itself.

Cover the area around the hole you have drilled using a bead of caulking material. Be certain to cover the hole entirely well. Turn the sink upside down and place it on the caulking. In case any water oozes or drizzles, wipe it away using a clean piece of cloth. Finish off by tightening the mounting screws.

Step IV: Assemble the components of the sink together

Proceed now drill yet another batch of holes on the sink for the sake of fixing the faucets. Mount the faucets on the sink thereafter. Now flip the countertop the right side up and attach it according to the rules laid down by the manufacturer. Fix the sink in place. Follow this by applying the plumber’s putty around the openings of the drain and down to the hoe snugly.

Leave the putty to sit upright overnight. The next morning, reconnect all of your water supply lines back to the sink and t the various other connections. Attach your drain trap to your drain pipe and join the two of them to the drainage.

Step V: Test the installation

Conclude the process by testing whether the connections and installations are foolproof. Do this by turning on the water and noting the manner in which the water responds. Check for any leakages and clogs. In case you note any, deal with them appropriately. Unclog the obstacles and seal the leakages.
