Repair rotten wood
When old timber becomes worn or rots away, reach for Alcolin QuikWood. This epoxy is made up of two components that harden when mixed together. With a consistency like dough, it can be moulded by hand but will hold its shape as it hardens. It bonds well to timber and holds up against weather. When dry, the filler can be sanded, primed and painted. And it also takes stain in a similar way to softwoods such as pine. Before staining, create fake grain lines by cutting into it with a utility knife. The timber-like illusion helps to disguise the patched-up work.
1. Remove the rot
Probe with a narrow chisel or screwdriver to find damaged areas (rotten spots are noticeably softer). Rot often occurs under paint, so don't assume it is sound because the surface looks good. Gouge or scrape away large chunks with a chisel.
2. Soak the timber
Apply Woodoc Wood Reviver. Woodoc Wood Reviver cleans and rejuvenates wood that was damaged by exposure to weather and the elements. It can be used on all types of wood and kills mould.
3. Apply the epoxy filler
Rebuild missing areas with Alcolin QuikWood. For deep holes, drive screws partly into the timber to anchor the epoxy. Smooth filler with a putty knife before it hardens, dipping the knife in lacquer thinner first to stop the filler sticking.
Protect timber from rain for a week or so before applying epoxy and paint or seal exterior repairs within three days as UV rays degrade the epoxy.
