I have a concrete windowsill at home, but I want to change that without spending too much money. I also dont want to break any of the concrete, but I want to cover it. I have found this windowsill cover: https://buitengevel.nl/categorie/vensterbanken/lignodur-overzetvensterbanken/?_gl=1*z413p2*_up*MQ..*_ga*ODUzNDE4MjQ3LjE3MTc1MDI4MTU.*_ga_GT0J1CMM7W*MTcxNzUwMjgxNS4xLjEuMTcxNzUwNDA1MS4wLjAuMA..
Is it possible to just glue over the concrete? I’m afraid that the concrete will suck too much of the glue for it to do it’s job properly…
Or is there something like a primer I need to use, so that the glue will be as strong as possible?
