Good Afternoon, I dropped a log on the corner of my sandstone veranda and cracked the corner of a large tile/slab. I have repaired/glued it back together using Selleys Liquid Nails Landscape construction adhesive. Now that it is dry I am keen to fill in the cracks as this part of the veranda is exposed to rain. What would be the best product to use as the sandstone is aged and no longer a sandstone colour, so I think using Selleys No More Gaps Bricks & Mortar Sandstone colour would be the wrong choice. Not sure is a mortar tint would work either? Any suggestions on what I should use or would I be better off doing nothing? I’m looking for a solution that does not draw attention to the crack. Many thanks in advance for any advice you can provide. Regards Sally
Hi @Sally8,
I apologise for the delay in my reply.
It can be challenging to match the exact colour of aged sandstone, so the crack might still be visible even after repair. However, over time, the repaired area may blend better with the surrounding stone.
Before attempting any further repairs, it might help to clean the sandstone with a high-pressure washer to remove the dark mildew build-up and reveal the original colour of the stone. This might make it easier to match the repair with the existing surface.
For now, I would recommend starting with a standard grey cement mix for filling the crack. The grey might be a decent match for the current colour of your sandstone. You could also try using an oxide to slightly tint the cement and get closer to the shade of the sandstone. Keep in mind that a perfect match might not be achievable, but with careful application, it should help minimise the attention the crack draws.
Please let me know if you have any questions.
Mitchell
