Welcome to the Bunnings Workshop community @Gordon937. It's sensational to have you join us, and many thanks for your question about repairing cracks in concrete.

You could either use Dunlop 5kg Floor Repairer Rapid Patch Mortar or Gripset Betta 1L Concrete Crack Filler. Both will provide a great result, though they will be concrete grey coloured. Are you planning on repainting the porch? If the paint is in good condition and not overly deteriorated, you can use our range of concrete paints.

Apply the repair products to the cracks and smooth over the surface with a trowel, pushing the mixture into the crack and providing an even finish. Once the repair product is dry, you can sand the surfaces to blend in the repairs. Remember your PPE, including safety glasses and a dust mask.

Please let me know if you have any questions.
