We have a floor on our caravan which has become spongy in the kitchen area.Is there a way that it can be repaired by myself to reinforce the floor without changing the floor.
What has happened is called delamination. Areas with heavy use are most prone ie. kitchen areas. To cure this you need to re-bond the area affected. You can obtain bonding kits from a company called Apollo Adhesives (www.apolloadhesives.com).
