    • Smith's Original and Genuine Fill-It is a non-sag epoxy filler for restoration of wood that is easily sanded and cures overnight
    • This epoxy filler represents a breakthrough in the technology of filling compounds
      • Through the use of advanced hydrogen bonding technology, Smith has produced a high strength, light weight, non-sagging, easily sanded epoxy filler
    • It consists of an epoxy resin and a curing agent which is derived from natural wood resins, and so is very compatible with wood
    • The two components are designed to mix one to one by volume
    • When mixed they become a gel which may be faired and worked to a feather edge
    • After one to two hours in moderate weather it begins to harden, and cures overnight
    • As soon as it does not gum up the paper it may be sanded, and primers or paints applied
    • It is easily carved or drilled, and screws may be driven into pilot holes without cracking
    • It has sufficient compressive strength that it maybe used to fill defects in Ferro cement boat hulls, and sufficient flexibility that it is suitable for wooden beams, windows and sills, doors or other parts of wood buildings as well as wood or fiberglass boat hull repair
    • This product was invented by a physicist and aerospace engineer with thirty years experience in the aerospace industry
    • It was designed to meet the same formulation standards as aerospace materials
    • It contains an aerospace adhesion-enhancing additive to give it aggressive and tenacious adhesion to wood, cement and a wide variety of materials
    • It is reinforced with glass fibers for extra tensile strength. In fact, all of the solid fillers or reinforcing additives are chemically engineered glass of one form or another
    • This gives the best long-term stability and moisture resistance
    • In order to ensure good adhesion of Smith's Fill-It epoxy filler to a surface, the first application should be a thin film smeared forcefully against the surface
      • An additional quantity may then be applied to build up to the required thickness
      • The uncured material may be tooled smooth and level by placing a clean new piece of clear 4-mil or 6-mil polyethylene sheet over the uncured material and using a squeegee or other tool to smooth the filler through the plastic
      • Leave the plastic film in place until the filler has cured, when the plastic film may easily be peeled off
      • In order to ensure adhesion of whatever primer or paint is to be applied next, it is recommended that Smith's Fill-It epoxy filler be sanded before painting
