Henry in MI

Tammy, hate to tell you this but there is nothing that will work other than taking out the panelling and putting up drywall. This is an easy job but very messy. Start by watching some of the home shows on TV and you will eventually catch one on how to do it. Drywall will probably end up being cheaper than trying to fill the grooves in your panelling, will not crack if you do it right and is the right product for what you want. Don’t forget to prime before you paint or paper your new walls.
