Welcome to the Bunnings Workshop community. Thank you for joining us and sharing your interest in the kitchen benchtop.
I have exactly the same benchtop at home and my children use it as their homework and projects table. In the time that they have used it, there have been spills and glue stains that are not too noticeable. I should have put a clear finish on it before I let my kids use it. Hot items have been placed on it with no serious damage.
My only recommendation is to use a clear sealer on it. This should provide you with an adequate line of defense against possible stains.
If you need any information regarding your kitchen renovation, please let us know.
