how to install a timber benchtop

Before you begin, make sure you’ve read through this guide before giving it a go. If you're using bamboo or solid timber, keep in mind that colour variations and natural patterns are part of what makes each benchtop unique.

step 1: check your benchtop

• Before any cutting or installation, inspect your benchtop for ‘Side A’ which should be used faced up on your bench.

• Timber benchtops may bow slightly if stored for long periods. It is recommended to lay it flat if not installing immediately. If your benchtop has bowed, flip over with the face down for a few days to correct it.

step 2: cutting the benchtop

1. Mark and scribe your cut lines using a sharp knife to reduce splintering.
2. Turn the benchtop upside down and re-scribe the cut line.
3. Use clamps to secure a straight edge as a guide for your circular saw.
Tip: Measure the distance between your saw blade and base edge to position the guide accurately.
4. Set your circular saw blade depth to about 10mm deeper than the benchtop thickness and make your cut slowly and steadily.
5. For cutouts (e.g. sinks or cooktops), use a jigsaw, and mask the area with low-adhesion tape to help avoid splintering.
6. Reseal all cut surfaces before proceeding.

step 3: joining benchtops

drill holes

• On the underside, mark a line 20mm from the edge to position your holes.

• Drill three holes spaced:

  • 100mm in from each edge

  • One hole spaced evenly between the two outer holes

  • Use a 35mm wide drill bit, drilling 25mm deep

add biscuits (optional but recommended)

• Mark evenly spaced biscuit locations between drill holes.

• Cut biscuit slots with a biscuit joiner and test the fit before applying glue.

• Add glue to both joining surfaces and biscuit slots.

connect the join

• Insert benchtop joiners and tighten with a 10mm spanner, starting from the front and working back. *Important: Don’t overtighten, as this may crack the timber.

• Use a rubber mallet to tap the benchtops flush if needed.

• Wipe away any glue with a damp cloth.

step 4: fixing to cabinets

1. Use the supplied 90° angle brackets and 14mm screws to fix the benchtop to the cabinet backs.

2. For support rails, use 28mm screws, but first drill an elongated hole (5mm x 2) to allow for natural timber movement.

3. If needed, drill 50mm holes in top rails to access joiners or pull the benchtop slightly forward while working.

step 5: sanding and sealing

1. Once glue is dry, sand the entire surface with 120 grit sandpaper, then finish with 240 grit for a smooth feel.

2. Apply at least two top coats of your timber sealant, ensuring even coverage on all surfaces and cutouts.

3. Once dry, seal between the wall/splashback and benchtop with a bead of silicone.

caring for your benchtop

• Wipe regularly with a damp cloth and mild soap.

• Avoid placing hot pots or using sharp objects directly on the surface.

• Clean up spills quickly to prevent staining.

• Re-sand and re-coat if the surface becomes worn or damaged over time.

With the right prep and care, your new timber benchtop will look great and perform beautifully for years to come. Whether it’s for cooking, entertaining, or just daily life, there’s nothing quite like the warmth and character of real timber in the kitchen.
