I used bleach to clean my whiteboard, and it took the finish off. Now the dry erase markers don’t wipe off, i have to scrub them. What could I use to resurface it?
Clear Coat would be a good option.
Start by sanding the board to get a rough surface, then paint it with the clear coating. Gelgloss works well. Rustoleom also makes white board paint.
You could also use a self-adhesive board skins to place over it. It’s extremely sticky on the back, so make sure to get it placed before you stick it on.
