Our Epoxy Wood Hardener is called Epoxy Primer Consolidator. This is a thin liquid two pack designed to flow easily into decayed wood, after the rotted fibres have been dug or machined out. Acts as a both a penetrating hardener and a wood primer. Non shrink, provides a strong bond for Epoxy Putty and Timbabuild Filler.
Wood decay needs to be cut out before our ultra effective wood hardener, Epoxy Primer Consolidating liquid is applied, in order to avoid sealing in pockets of rot that might continue to decay in the long term. Once the wood Primer Consolidator has soaked in our surface fine filler, Timbabuild can be applied, for holes less than 20mm deep, or our Moldable Epoxy Putty can be used instead in deeper holes, to reduce costs. After the Wood Hardener and Timbabuild, or Moldable Epoxy Putty, have dried hard the wood can be drilled for the insertion of Boron Paste and Boron Rods, to prevent future decay in the remaining timber. These 10mm holes should be plugged using our plastic DPC Plugs, or wooden dowel, or wood filler. Cutting out of rotted timber can easily be achieved using our 3D Cutters, available in diameters from 6mm to 32mm.
Our wood hardener Primer Consolidator is non-flammable, does not contain any solvents and does not shrink or separate over time.

Hardening Decayed Wood
Unlike Retail wood hardeners we do not use acrylic, polyester or solvent based resin hardeners because they are not epoxy-based, and although they may make the wood hard they do not restore substantial strength. They can also be chemically unstable due to long-term exposure to moisture in the wood, the cause of decay and every present in external joinery. Epoxies are not affected by this dampness, do not shrink and will not deteriorate inside the wood with age.
