Can Original Black Wax Undercoating In A Can be applied to the wood floor of a trailer?
Original Black Wax can be applied to wood, but it should be the underside of the wood. It is not suitable for wood that will receive any pedestrian traffic.
Can this undercoating be applied to plywood underneath a camper?
The Original Black Wax and Clear Wax are excellent sealers for wood. The largest shipping company in the US specifies the wax to protect the steel undercarriage and wood floors of their over the road trailers. Trailer manufacturers apply the wax undercoating to the entire steel and wood undercarriage for the over the road trailers because it seals the wood and repels moisture. It is abrasion resistant too so it protects the wood from road debris that may be propelled into the wood.
