Application of a flame retardant and mold inhibitor penetrant composition to porous interior building material surfaces

Claim Score by NHIP

Read claim 5, the broadest

Abstract

A process for the single application of one (1) to ten (10) treatments of a penetrating aqueous chemical composition to impart the combined properties to retard fire and inhibit mold growth on Gypsum Wall Board, Ceiling Tiles, Joint Compounds, Concrete, Wood or Manufactured Wood products and other porous interior building material surfaces. The primary embodiment consists of a composition containing Potassium based salts, a Boron containing compound, a registered commercial mold inhibitor and a surfactant, all of which are compounded as an aqueous solution of the chemicals. Other embodiments in addition to the above can include, but are not limited too, inorganic and organic salts of Alkali Metals, such as, but not limited to, Potassium, Sodium, Lithium, Magnesium, Carbonates, Acetates, Phosphates, Citrates, Lactates or Urea, Halogens, Ammonia or any combination of these materials.

  1. 1
    A process for applying one (1) to ten (10) treatments at the rate of one gallon per 300 to 600 square feet, of an aqueous combined property, flame retardant and mold inhibiting penetrating composition, with a single application per treatment to new construction production run Gypsum Wall Board.
  2. 2
    A process for applying two (2 ) treatments, at the rate of one (1) gallon per 500 square feet of an aqueous combined property, flame retardant penetrating composition, with a single application per treatment to new construction production run Gypsum Wall Board, as a preferred mode.
  3. 3
    A process for applying one (1) to ten (10) treatments, at the rate of one (1) gallon per 300 to 600 square feet, of an aqueous combined property, flame retardant and mold inhibiting penetrating composition, with a single application per treatment to previously painted Gypsum Wall Board, for refinishing or rehabilitating by repainting.
  4. 4
    A process for applying two (2) treatments, at the rate of one (1) gallon per 500 square feet, of an aqueous combined property, flame retardant and mold inhibiting penetrating composition, with a single application per treatment to previously painted Gypsum Wall Board, for refinishing or rehabilitating by repainting, as a preferred mode.
  5. 5
    Broadest claimClaim Score 94, very broad(NHIP)The addition of a Cationic, Anionic or Nonionic surfactants to flame retardant and mold inhibiting penetrating aqueous compositions.
  6. 6
    An aqueous, combined property, fire retardant and mold inhibiting penetrating composition applied with a single application by brushing, spraying, wiping or immersing to Gypsum Wall Board, Ceilings, Joint Compounds and Tape, Concrete, Wood or Manufactured Wood products and other porous interior building material surfaces.
  7. 7
    An aqueous, combined property, fire retardant and mold inhibiting penetrating composition applied with a single application to Gypsum Wall Board, Ceilings, Joint Compounds and Tape, Concrete, Wood or Manufactured Wood products and other porous interior building material surfaces composed of Inorganic and Organic salts of Alkali metals, such as, but not limited, to Potassium, Sodium, Magnesium and Lithium Carbonates, Acetates, Phosphates, Citrates, Lactates, or Urea, Halogens and Ammonia or any combination of these materials plus a boron containing compound such as, but not limited to, boric acid.
  8. 8
    An aqueous fire retardant penetrating composition, applied to Gypsum Wall Board, Ceiling Tile, Joint Compounds, Joint Tape, Concrete, Wood or Manufactured Wood products and other porous interior building material surfaces, containing Potassium Carbonate in the amount of twenty percent (20%) to forty-five percent (45%) by weight, a Potassium salt of an organic acid in the amount of five percent (5%) to twenty-five percent (25%) by weight, and Boric acid or Boron containing compounds in the amount of two percent (2%) to six percent (6%) by weight with the remaining weight being water, as a preferred mode.
  9. 9
    An aqueous fire retardant penetrating composition, applied to Gypsum Wall Board. Ceiling Tile, Joint Compounds, Joint Tape, Concrete, Wood or Manufactured Wood products and other porous interior building material surfaces, containing Potassium Carbonate in the amount of thirty five percent (35%) by weight, Potassium Acetate in the amount of thirteen percent (13%) by weight and Boric Acid in the amount of two percent (2%) by weight with the remaining weight being water, as a most preferred mode.
  10. 14
    An aqueous, combined property, fire retardant and mold inhibiting penetrating composition that can be applied with one (1) to ten (10) treatments at the rate of one (1) gallon per 300 to 600 square feet per gallon, with a single application to both sides of the paper binding gypsum wallboard.
