Wood & PolyAll 2000
PolyAll 2000 readily absorbs into wood. This means that it can be used to seal wood against water including salt water, contamination, insects, mold, and fungal damage. It can also be used to reinforce and repair wood rotten wood which has rotted (dry rot), split, or has become structurally unsound through shrinkage or aging.
PolyAll 2000 infiltrates the wood and then turns to a hard and strong urethane plastic inside the wood. The more porous and cracked the wood, the deeper the penetration. Wood which would crumble in your fingers will, with the proper application of PolyAll 2000, accept a nail or a screw and regain much or all of its original structural integrity.
The application of PolyAll 2000 for the restoration of antiques, decorative or structural woodwork in historical and century homes rotten wood repairor even fence posts rotten wood repair and garden gates rotten wood repair is unlimited.
Two Things Will Affect Your Repair
1The wood that you are repairing must be dry. PolyAll 2000 will not work on water soaked wood so make sure that you dry it properly. Woods that contain a lot of natural oils such as Mahogany or Teak will have to be wiped well with wood alcohol to eliminate surface oils and make room for penetration. In areas that are rotted, natural oils have been eliminated and this step should not be required. The denser the wood the less penetration that you will get.
2The age and type of wood. A brand new piece of Ash will not absorb much PolyAll 2000 while a new piece of Pine will absorb quite a large amount. Both woods will however benefit from the proper application by becoming sealed to the elements, airborne pollution and most things that will adversely effect wood. Old wood will always absorb quite a lot of PolyAll 2000 as it infiltrates the open pores and cracks that are a result of wood losing its moisture over the years.
PolyAll 2000 Has Many Different Uses
From casting to sealing to use as a replacement for fiberglass resins, but nowhere is its use as extraordinary as it is with wood. To use it on wood, apply it following the mixing instructions provided with each kit initially using no fillers. PolyAll 2000 comes to you in a very watery fluid and will achieve its greatest penetration by simply brushing or pouring it onto the wood. You should continue brushing it on for as long as it continues to be absorbed and disappear. Depending on the wood deterioration and softness, you should continue to apply PolyAll 2000 for several minutes until it starts to run or puddle on the surface. At this point the wood will have absorbed the PolyAll 2000 as deeply as possible. By dropping the temperature of PolyAll 2000 or by cooling the two components below room temperature you can slow the hardening and this under some circumstances may allow deeper penetration should you require it. This will usually not be required under most applications. At room temperature the PolyAll 2000 should set up inside the wood in 8 to 10 minutes. You may notice an oily feel to the surface which will disappear as complete set up occurs.
After set up, the wood can be nailed, sawed, drilled, sanded, painted, etc. If the piece of wood that you are working on has holes and irregularities that you want to fill you can do so now by adding sawdust or any other dry filler to PolyAll 2000 and spreading it into the holes that you want filled. If the hole is from one side to the other you can dam it with tape or putty to trap it and keep it in place. Although PolyAll 2000 will not shrink, it can leak out of the holes unless you keep the subject piece level, so make sure you don't tip it. PolyAll 2000 has a very low viscosity so it can be channeled into hard to get to areas by drilling small feed holes or by injecting it with hoses, funnels or blaster.
An important item to remember is that the wood must first be stabilized and rebuilt by saturating with PolyAll 2000, then do any filling of missing wood, holes, etc. on the second application. When filling on vertical or uneven surfaces is required follow the mixing instructions for using fillers in which the PolyAll 2000 can be mixed to a thickened consistency which can be spread onto the work.
