We recently acquired a children's castle that was custom made originally. It seems to be completely made of MDF. The stairs are only held together by nails and they are coming apart in certain sections (top left & bottom right).
I tried pushing it back together and driving the nails back in, but it slides back out on its own over time.
What options do I have to repair this?
Here are some of my initial approaches I was thinking about:
- Wood glue and #8 deck screws but I'm not sure how well that will hold on painted MDF
- Create "bridge" underneath the top and bottom with 2x4's. Then screw from the outside into the frame with some large washers to ensure the screw doesn't pass right through
- Use metal "L" brackets underneath each problem step
