In the case with Abatron products, the consolidant (LiquidWood) is a two part viscous material that when mixed in equal parts and applied to rotted and decaying wood, reinforces, rebuilds, and waterproofs the offending material. It is the first step in the restoration process and is applied before the wood filler. Once the consolidant becomes tacky, the wood filler can be applied.
The filler (WoodEpox) is also a two part system but comes in a two color dough form. The dough is a high-strength, no-shrink structural adhesive putty. Once again, equal parts are mixed to form a uniform substance that can be used to fill even large holes, cracks, and rotted areas. To smooth the dough, one only need dip the putty knife in some isopropyl alcohol and carefully work the material. Once the dough has set, it can be sanded, shaped, and routed. It can also be tinted with dry pigments when combining the two parts, and stained, or primed and painted afterward.
It is important to remember two things; the consolidant goes a long way, so only mix a small amount at a time. In addition, the working time for the wood dough is only about twenty minutes, so only mix up an amount that can be worked in that timeframe to avoid waste. It is also important to remember that since the WoodEpox generates heat as it cures, the larger the mass, the quicker it cures due to the amount of heat generated and trapped within the mass. Thus, thin applications will take longer to cure.
When used correctly, wood consolidants and filler can produce a very professional end result. In addition, these products allow the homeowner greater autonomy in the hands-on restoration process. It is true that certain situations will require wood replacement, but the Abatron process allows for many jobs that might otherwise be sent out to be completed on site and at a greatly reduced cost.
