Caravan floor delam spongy and springy

Springy floor? feels like your going to fall through the floor! maybe the floor feels like a trampoline.

The adhesive breaks down or the polystyrene breaks up and comes unstuck from the plywood floor material.

With a little time you can easily drill a series of carefully measured holes and inject adhesive and plug with 8mm x 30mm wooden dowels.

The advantage of using the one shot floor adhesive is that you can use what you need and then put the cap back on and save the rest. Less waste and less messy.

*Important to note when using one shot polyurethane always wear gloves and a mask.

*If the floor is made up of polystyrene balls that has all broken up you can use slightly more adhesive than if it's made from a dense styrofoam material. If dense styrofoam use sparingly as too much adhesive can cause the floor to bulge up as the adhesive expands slightly.
