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.
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.
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.
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.
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.
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.
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.
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.
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.
Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. 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 or visit our Health & Safety page.
