How to join timber panels to form L-benchtop on pantry cabinets?

[barydos]

Hi there!

I'm going to be installing some kitchen cabinets in our small pantry and need some advice about benchtops as it will need to fit an L-shape over the cabinets.

I'm thinking of a long bench top spanning across the wider pantry over the gap and onto the corner cabinet top. Then I'd complete the L-shape with a smaller panel over the remaining space over the cabinets (which will join to the high cabinet). The cabinets have a depth of 37mm. What's a recommended overhang for benchtops?

I was thinking of something like this panel (https://www.bunnings.com.au/specrite-1800-x-405mm-18mm-timber-panel-beech-fj-laminated_p8330198) with a couple coats of polyurethane. 

What's the best approach to making the L look nice? I think I'll leave a 5mm (or less) gap to the walls and high cabinet and caulk those gaps, but what's the approach to join the two bench tops together. They will all be secured to the cabinets from the underside, but not sure how to deal with the butt joint part.

Thanks!

Hi @crisis,

I'd suggest using a silicone sealant like this Selleys Wet Area Waterproof Silicone Sealant.

You might also need to add some 6mm Gap Filler Rod in the wider spots to stop the silicone from falling through the gap before it can set.

Let me know if you have any further questions.
