Structural Drying >> Mold Mitigation

These Mold Mitigation tracks are traits of Douglas-fir, pines, spruces and larches and are readily visible to your naked eyes, or under a low power magnifier on the end grains of planks and logs. In ponderosas, white and sugar pines, resin tracks are obviously visible as thin, brown stripes on the surfaces of lumber. Sometimes, other species might create localized bands of vertical resin tracks in response to pain to the cambium, i.e. western hemlocks and redwoods.

  1. Kiln Mold Mitigation lumber from this species would tend to set resin and reduce later exudation if lumber is subjected to heat in the modern house. The woody part of a living tree constantly is fluxed with water which is present in different forms, 'free' water as confined to the cell chasms and 'bound' water which may saturates the cell walls. The humidity substance of wood is expressed as a per cent, i.e. 50%, which is a ratio value of the mass of water to the oven-dried mass of wooden substance, represented by the Mold Mitigation formula: Per cent H.S. = Mass of water x 100 Oven-dried mass of woods.
  2. Many species usually have more wood substance per unit volume (density), i.e. comparing hickories with western red cedars. Consequently, at any given Mold Mitigation humidity substance per cent figure wood from different species actually would contain a variable quantity of water per unit volume (plank foot or cubic foot). For archetype, at 50 per cent humidity substance a plank foot of hickory might contain about two pounds of water whilst a plank foot of western red cedars might contain about one pound of waters. Of particular importance in Mold Mitigation wood is the presence of bound waters confined to the cell walls (wood substances).
  3. When any parts of the cell edifices of a piece of wood has dried to the point that any free water is extracted and only bound water endures, that wood cells involved have reached their 'fibrous saturation points' (a figure of about 45 per cent humidity substance for most practical purposes). Further Mold Mitigation extracts bound water from its close contact with the chemical cell-wall features (principally cellulose) to cause the walls of these cells impacted to shrink (or desire to shrink). The chemical features comprising the largesse of wooden substances often are pointed more or less parallel to the vertical axis of wooden cells.
  4. With water lost from between these features, it is obvious that most shrinkage happened perpendicular to the axis of all wooden cells. It isn’t that 93 per cent of the cell edifices in conifers are comprised of long, slender cells paralleling the length of logs and/or lumber. Therefore, almost 100 per cent of the shrinkage often developed in a plank is in its girth and thickness. Usually, the quantity of shrinkages in a plank might be correlated to the character and quantity of summerwood present since this substance very much controls density. Vertical shrinkage usually is very low, less than one-half of one per cent in wood of normal Mold Mitigationprogress.
