Headliner Material Falling Down, Roof Sagging

SPONSORED LINKS

How to fix the headliner material that is falling down, sagging? This weekend we spent some time fixing  the ceiling material which started to sag down on a C Class. This is a common problem on the older Mercedes Benz and not just on the C class, but the E Class, S Class, ML all models for that matter. We wanted to show you what we did.  The cloth material separates from the sliding sunroof as well. This is our roof of the Mercedes Benz C Class.

There are three options to fixing the headliner.

Option 1 – Best results

  • Using a spray adhesive. This is what we used. See the pictures below on how we did it. You can do this with the headliner in the car, which is what we did below. Ideally you can remove the headliner foam material, clean out the surface and glue the headliner, for longer lasting results.

Option 2 – Quick and easy

  • The other option to fix the headliner is to use the Sequin Pins. You can use the little pins to hold up your headliner. You will may want to use a few of them arranged in a pattern. For example you can set them up in a diamond pattern or square pattern. You will be able to see the small pins, but if you are creative with your pattern you may be able to make it look like your Benz was made that way at the factory. April, a creative wife +moom + crafter used this method, you can read her post here and check out the pictures of how it looks in her car.
  • Or you can use the Twisty Pins for Upholstery. You choose.

Option 3

  • You can replace the whole headliner. You can get a new headliner from the dealer or online. This is the most expensive option but has the factory results.

  4. Wait about 5 minutes for the adhesive to become sticky. Read the directions on the can for the exact time you need to wait.
  5. If you can’t get to a specific spot then separate a small area of the headliner which will give you room to spray the rest of the material in the inside.

  7. Go over the headliner and press it against the roof every few minutes. It may want to sag again, but if you press it up a few times in the next 20 minutes than it shouldn’t fall down anyone.
