Stacked stones being placed in layers against a blue board wall

Overview

Improve your barbecue area with a stylish stacked stone feature wall. It's definitely a job that you can do yourself and we'll show you how. You'll learn how to prepare the wall, measure and cut the stacked stone pieces, and attach them to the wall, using adhesive.

Steps

1Clean and seal the area

First, clean the area you're planning to turn into the feature wall.  Then, use an outdoor silicon product around the edges. Scrape off any excess silicon with an icy pole stick.

2Mix the primer

Now mix primer and water in a bucket. Make sure you read the instructions on the pack to get the correct water to primer ratio.

3Prime the surface

Now apply the primer the area, using a brush or roller. Make sure you cover the whole substrate and leave it to dry for 15 minutes.

4Dry lay the first row of stacked stone

Stacked stone is made from natural stone and has variations in colour, texture and thickness. So before you apply any adhesive, dry lay out your first row against the wall to help you work out the look you want.

5Measure and cut the stacked stone ends

Once you've dry laid your first row of stacked stone, you're most likely to have a gap at the end. Measure the space and transfer those measurements to a piece of stacked stone, using your measuring equipment. Now cut stone to size. Then place it in the gap to make sure it fits.

6Mix the adhesive

Mix the adhesive powder and liquid in a bucket until it's a toothpaste consistency. Again, make sure you follow the instructions to get the correct ratios.

7Apply silicon to the back of the benchtop

Remove the dry laid row of stacked stone. Then apply a bead of silicon at the very back of the benchtop. This will help seal the first row of stacked stone to the benchtop.

8Apply the adhesive

Take your trowel and spread the first course of adhesive at the bottom of the wall. Apply enough for the first couple of rows of stacked stone.

9Attach the stacked stone to the adhesive

Now lay the first row of stacked stone onto the adhesive. Lay from the bottom and work your way up, applying more adhesive to the wall as you go. When making overlaps, don't worry about lining the joins up perfectly because it generally looks better off-centred. Just lay the stone to look as natural as possible.

10Cut the top row to size

When you reach the top, you're more than likely to have an uneven space left for the final row.  Measure the remaining space height and use an angle grinder to cut the stack stone pieces to size.

11Lay the top row of stacked stone

Then lay the final course of stacked stone along the top row. It's best to apply the adhesive to the back of the stone, rather than to try and trowel it over a small section of wall. Clean up any mess with a sponge and water, and leave the wall to dry.

Health & Safety

Please make sure you use all equipment appropriately and safely when following the advice in these D.I.Y. videos. You need to be familiar with how to use equipment safely and follow the instructions that came with the equipment. If you are unsure, you may feel it is safest to consult an expert, such as the manufacturer or an expert Bunnings Team Member.

Grave health hazards are linked to asbestos, which may be in homes built up to 1990. Health hazards may result from exposure to lead-based paints in older materials and copper chromium arsenic (CCA) treated timber. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer. You can also use a simple test kit from Bunnings to indicate the presence of lead-based paint.
