Installing a new Formica Life seal worktop around your kitchen sink

The countertop around your kitchen sink can be prone to water damage and may need to be replaced from time to time. Formica LifeSeal Worktops are a popular choice in the kitchen – they are affordable and durable, they come in a range of different colours and patterns, and are easy to install.

Step 1: To replace a worktop around a kitchen sink, start by removing any appliances or fixtures in contact with the worktop, such as sinks, taps, preparation bowls or ovens.

Step 2: Remove the fixing screws from underneath and use a craft knife to cut through any areas where the tops are sealed with silicone.

Step 3: Get the new top cut to fit exactly where the old one used to be. You can do this yourself or you can get the tops cut at a specialist board cutting shop.


Step 4: Make sure you measure for the cut in the worktop precisely. Do this by placing the sink upside down and in place on the new worktop. Then draw a pencil line carefully around the edge.

Step 5: Remove the sink and draw a second, more prominent line inside the first line. This is to accommodate the lip of the sink. In most cases, the lip is 19mm.

Step 6: Drill an access point for the jigsaw blade with a 12mm drill bit just inside the lip line. Then cut carefully all along the line using your jigsaw.

Step 7: With the cut complete, you are ready to fit the sink. Start by sealing the cut edge with PVA; this will not be visible, and will give the naked edge some resistance against moisture.

Step 8: If the sink came with a rubber seal, attach it to the lip, alternatively use a silicone specifically formulated for use in the kitchen to seal between the sink and worktop.

Step 9: Put the sink in place and tighten the securing clips from under the sink. To ensure a watertight seal, put more silicone around the edge and clean any excess with a clean cloth dipped in spirits.
