Do You Mitre Square Edge Worktops

When it comes to cutting and joining square edge worktops, these are somewhat different to bullnose worktops as you don’t need to mitre a square edge worktop this is due to them being square, and you can just butt them together

When it comes to wooden worktops tops, you can just butt them together, seal the end with silicone or join mitre sealer and join them with worktop bolts

When it comes to square edged laminate worktops, this can be different.

If you have a fully laminate front edge to the worktop, then you will need to measure the depth of the worktop and then to use a chisel remove the laminate from edge

If you don’t remove the laminate front edge, you will most likely have a poor and untight join

Once you have removed the front laminate, then you can just butt them together sealing them with silicon or mitre seal and tighten with worktop bolts

The worktops are now ready to be installed onto your kitchen cabinets

Once you have cut both worktops place the worktop with the female cut in place and lay the male worktop on the top.

Firstly dry-fit the worktops to make sure they are both going to fit, and the join looks good.

If the worktop join is right, then lay the bolts into the female worktop cut-outs and then using silicone, run and small bead on the front edge and across the top of the male joint

Slowly line up both worktops and push them together now you can start to tighten the bolts

Start with tightening the front bolt so that it starts to pull both the worktops together but don’t overtighten.

Repeat the process until all the bolts are tight, then clean of the silicone seal

How Far From A Sink Should A Worktop Joint Be

When planning for the fitting of kitchen worktops and locations of your sink and hob you need to think about the way the worktops are being joined to allow for the installations of the bolts

It is the best practice that you make sure when joining worktops together you allow 100mm space away from any appliance cut out so that the worktop bolts do not interfere with the installations of a sink, hob or any other appliance that is cut into a worktop.
