No matter if you are starting from scratch or refurbishing an older kitchen with laminate or wooden worktops, if your goal is a secure connection, then there are a few steps you must follow to join them in a way that ensures they remain strong and stable. Prepare worktops for installation. This step ensures a sleek finish to your worktops!

Cutting away excess material around each edge and using a router with an appropriate worktop jig to create an even and neat joining edge are two critical steps in installing new worktops. Care should be taken not to damage them with excessive force when using this jig; please follow all manufacturer’s instructions when using it.

When installing a new kitchen sink or hob, cutting holes is also part of the installation process. Be sure to take accurate measurements so as to save both time and money by not having to recut your worktop later on.

Joining two pieces together involves various methods, but one effective option involves cutting a Mason mitre with a router and worktop jig, creating an aesthetically pleasing corner joint while remaining durable over time.

Route a dogbone-shaped groove into both worktops’ undersides, then insert special worktop bolts. This method provides a straightforward and cost-effective solution that works equally well for laminate and wooden materials.

If you need to join worktops along straight or corner edges, specially profiled aluminium joining strips are available that can be screwed in place and covered with silicone sealant for an attractive solution. Although this method doesn’t provide as much strength as full mitre joints, it does make assembly much simpler and look nicer.


Instructions for joining worktops vary based on the material being used, but certain principles always hold. Laminate and wooden worktops are commonly seen in UK kitchens and while their specific instructions may differ slightly, several principles remain the same for both. First of all, when cutting the two worktops, it is essential that they are securely supported on planks or trestles to prevent movement and cracking while making cuts; similarly, it is crucial that once joined, they be held steady when being glued together so as to prevent glue seeping into cracks in surfaces to achieve more even joins between surfaces, creating more even joins between surfaces as glue is forced between surfaces, creating more even joins than ever before!

If the worktop will fit at a right angle, male and female Mason mitre joints must be cut using a Trend jig and router fitted with an appropriate collet. However, this is an inherently tricky job and most homeowners opt to hire professional services when having worktops cut, as this involves needing to sand and smooth the edges afterwards.

Worktops must also be joined together evenly, particularly around any cutouts for sinks and hobs. Achieve this with worktop-coloured filler that creates an invisible joint by simply rubbing it into place. There are numerous colours to choose from and this filler just needs to be quickly rubbed in for maximum effect!

Most worktop lengths are designed to overhang cabinet doors by some distance, so to prevent loose and unsightly worktops, it is crucial that they are attached securely with joining bolts purchased at any DIY or builders merchant and screwed and fastened into place. Joining bolts are widely available from DIY and builders merchants and can easily be installed using drilling.

Finally, applying waterproof sealant along the joining edges of both worktops is highly recommended to protect them from water damage and bacteria while making their surface more visually appealing.


Sealing joins to prevent moisture from entering gaps and leading to water damage is paramount, but sealing around sink cut-outs and tap holes is also essential in order to avoid mould and mildew growth. Sealing these areas will stop mould from growing within moisture trapped between gaps, helping keep worktops hygienic while also avoiding discoloration due to mould.

Most manufacturers suggest the use of sanitary silicone sealant to plug any holes, providing an effective barrier against water penetration. Available at DIY and home improvement stores in various sizes, it is crucial that you read instructions thoroughly to select the product best suited to your worktops.

When fitting a new kitchen worktop to an existing cabinet, it is crucial that all joints are sealed correctly. This step plays an essential part in the finished product, as worktops will likely come under heavy use from cabinets or appliances such as cookers.

Wood sealant of sufficient quality should be suitable for sealing joints in worktops and appliances, although this must be left to dry before installing any appliances and using worktops. Incorporating some methylated spirit may help clear away dirt or grit that might have become trapped within the sealant.

Sometimes it may be necessary to cut worktops to create a joining strip, which must then be sealed over. This step becomes especially essential when butting two worktops together into corner spaces where tight joining strips are essential in creating an attractive yet sturdy finish.

Routing a dog-bone-shaped groove into the underside of worktops to secure them together can be done using a special routing jig, while worktop bolts may also be used to pull the joint tighter. After sealing this joint tight and sealing up its joining edges, this area may then be sanded to achieve an attractive and sleek finish.


Maintenance of worktops can be an ongoing endeavor. Regularly applying DIY cleaners and an effective disinfection regimen are necessary to keep surfaces looking their best, but care must be taken not to harm materials in any way.

Sanding worktops requires both expert knowledge and professional-grade tools for success. A mason’s mitre joint requires precise angles that may be hard to reach without appropriate equipment and knowledge.

When cutting a worktop, its surface must be properly supported in order to avoid warping and damage, either using clamps or having someone hold it while cutting. After cutting has taken place, all edges of the worktop must be sanded to smooth any rough patches and ensure an even, seamless finish. This step is especially important with natural stone or more expensive worktops.

Before embarking on any permanent joining, a dry fit should always be conducted as a first step. It will reveal any last-minute adjustments that need to be made and will ensure a seamless join. Professionals typically perform multiple dry fits as quality control checks.

Once worktops have been cut and sanded, it is imperative that they be thoroughly cleaned and disinfected in order to reduce bacteria buildup and ensure a strong bond with their final seal coat.

Worktops can be sealed using various sealants, depending on their material composition. Water-based sealants should suffice in most instances, though it would be wise to consult a specialist regarding which one would best fit your worktops.

Wood, quartz, and solid surface worktop materials are some of the most durable options, offering natural stain resistance and a variety of colours that complement any kitchen. While these may be pricey options to install yourself, professional installation services should usually be enlisted as needed for the best results.

If you’re searching for more cost-effective flooring options, engineered quartz or a solid surface might be your ideal choice. Both surfaces are easier to maintain while still looking authentic with realistic textures and hues. They’re also nonporous surfaces, which resist bacteria growth as well as dirt buildup more effectively than more porous options like carpet.
