Can not delete material

I have a stairway attached to a house and when I joined the two objects ( or when I removed doubles?) the stairway took on the material of the house. I have separated the two objects but when I delete the material the stairway retains the same colour even though it shows up as not having a material assigned. Any ideas please.

Hmmm I think this problem has something to do with the material index. Go to the EditButtons and go to the “Link and Materials” panel. Try playing around with the “New” “Delete” “Assign” buttons under the “Material” text and the “1 Material 1” field.

I don’t know if this will help you any…I could fix it if I had your blend file. I am a very visual worker…sorry for not being of help :frowning:

Thanks for your input and sorry for wasting your time, I’m an idiot there was a duplicate of the stairway on top of the original. Don’t know where it came from, maybe I’ve been spending too much time looking at screens?
