Wet Rot
Wet rot
occurs only where wood is damp. Normally, the attack does not spread across or
through brickwork. The signs of wet rot are a darkening and softening of the
timber, with cracks, usually running along the grain. There might also be narrow,
dark brown fungus strands on the surface of the wood. Wet rot can occur
anywhere but is a particular problem in roof timbers, underfloor joists,
windows and external doors. To treat wet rot, all infected timber should be cut
away with a saw and/or a chisel until you get back to sound wood. Check the
surface of the timber by using a sharp-pointed tool, such as a bradawl. With
floor joists and rafters, check by drilling into the middle of a joist or
rafter that they are sound in the middle. Small amounts of wood removed (as in
window and door frames) can be treated with Cuprinol Ultimate Repair Wood
Hardener and filled with Ultimate Repair Wood Filler.
