Decay on oak trailer floor under steel plate

Thus, to increase the service life of a laminated hardwood floor,
the moisture protection of the hardwood floor needs to be improved:
In the last 4 years, Prolam has done a lot of research and development to come up with a simple and affordable solution to improve the moisture protection of the hardwood trailer floor.
For the bottom of the hardwood floor, PROLAM proposes to use a polyurethane hot melt type undercoat which is a lot more durable than the standard water based undercoat generally used by the trailer manufacturers.
For the top of the hardwood floor, Prolam proposes to use WAXIN protection, an innovative protective solution. WAXIN is a process forcing paraffin into the surface of the hardwood making it more resistant to moisture. WAXIN reduces the deterioration of the floor over time. In combination with Borate, WAXIN is the best solution available to protect your hardwood trailer floor against decay. See the annexes for more details of WAXIN and borate preservative.
