Step 2: Remove the old foam
This is the second step in re-covering a car headlining with suede, and it is the one that matters most. Get the foam removal right and everything after it goes smoothly. Skip it and the new fabric will not last.
Why this step is so important
Under the old fabric you will find a thin layer of foam stuck to the board. Even if your roof lining was not peeling or sagging, that foam still has to come off.
New spray adhesive will not bond properly to old, crumbling foam. If you leave it on, the new suede can lift or bubble later, however careful you are with the rest of the job.
The rule is simple. The cleaner you get the board, the better the new fabric sticks.
How to remove the foam
Start with a stiff hand brush and work the foam loose across the whole surface. This is slow going on its own, so for the larger flat areas a drill with a brush attachment speeds things up a lot.
For the corners and edges, switch to a smaller metal-bristled brush, or a screwdriver fitted with a brush head. These let you get into the tight spots a larger brush cannot reach.
Keep going until the board feels clean and smooth with no soft foam left behind. It is the most tedious part of the project and can take a few hours, but it sets up everything that follows.
Common mistakes to avoid
- Stopping too soon and leaving patches of foam on the board.
- Pressing too hard with a drill brush and gouging the board surface.
- Skipping the corners, which are the easiest spots to miss.
FAQ
Do I really need to remove all the old foam?
Yes. Any foam left behind gives the new adhesive a poor surface to grip, which is the main reason re-covered headlinings fail.
What is the quickest way to remove headliner foam?
A drill with a brush attachment is the fastest method for the large flat areas. Use a smaller hand brush for the corners and edges.
Once the foam is off and the board feels clean, the next job is a final check of the surface before any adhesive goes near it.
