This invention relates to paper products and/or substrates suitable for being made into wallboard tape (also may be known as joint tape and/or drywall tape) and having improved reduction or inhibition in the growth of microbes, mold and/or fungus. The paper substrate is characterized by its excellent physical properties including cross direction (CD) tensile, machine (MD) tensile, internal bond, wet tensile, hygroexpansivity, curl, bonding properties, bonding of joint tape to joint compound, etc. The paper product of the invention contains a sizing agent and an antimicrobial compound as well as other optional components including without limitation a binder. The paper product of the invention may be produced by contacting the plurality of cellulose fibers with each of the sizing agent, antimicrobial compound, and optional components at any point in the papermaking process, converting process, and/or post-converting process. Finally, the invention relates to methods of using the paper substrate.

1. A wallboard joint tape, comprising a web of cellulosic fibers;at least one antimicrobial compound;at least one acid-based sizing agent; andoptionally starch; whereinpolyvinyl alcohol is not present;the antimicrobial compound is present at an amount ranging from about 10 ppm to about 5,000 ppm;the sizing agent comprises a combination of alum and rosin-based sizing agent and is present at an amount ranging from about 0.5 to about 1.5 wt %; andthe starch is present at an amount ranging from 0.0% to not more than about 5%. 2. The tape according to claim 1, further comprising at least one surface that is abraded. 3. The tape according to claim 1, said tape having: a basis weight ranging from 50 to 120 lb per 3,000 sq. ft.;a cross-direction Tensile ranging from 5 to 50 lbf/inch width as measured by Tappi Test Method T 494 om-06; anda thickness ranging from 0.006 to 0.012 inch thickness as measured by Tappi Test Method T 411 om-05. 4. The tape according to claim 1, wherein said sizing agent is present within the web and the antimicrobial compound is present at the surface of the web. 5. The tape according to claim 4, wherein said surface of the web has a nap thereon. 6. The tape according to claim 1, which has a pH of 1.0 to 6.9. 7. A method, comprising contacting a paper substrate comprising a web of cellulosic fibers with an acid-based sizing agent and an antimicrobial compound, and optionally starch, to produce a wallboard joint tape, comprising a web of cellulosic fibers;at least one antimicrobial compound;at least one acid-based sizing agent; andoptionally starch; whereinpolyvinyl alcohol is not present;the antimicrobial compound is present at an amount ranging from about 10 ppm to about 5,000 ppm;the sizing agent comprises a combination of alum and rosin-based sizing agent and is present at an amount ranging from about 0.5 to about 1.5 wt %; andthe starch is present at an amount ranging from 0.0% to not more than about 5%. 8. The method according to claim 7, further comprising abrading or sanding a surface of said web. 9. The method according to claim 7, further comprising abrading or sanding a surface of said web prior to said contacting. 10. The method according to claim 9, wherein said contacting comprises contacting said antimicrobial compound with said surface of said web. 11. The method according to claim 10, wherein said contacting said web with said antimicrobial compound is performed using a size press, a coater, or a sprayer. 12. The method according to claim 7, wherein said contacting said web with said antimicrobial compound is performed using a size press, a coater, or a sprayer. 13. The method according to claim 7, wherein the tape has a pH of 1.0 to 6.9. 14. A method of reducing, inhibiting, preventing, stalling, and/or retarding the growth of mold or fungus on a wallboard, comprising bonding the tape according to claim 1 to said wallboard. 15. The method according to claim 14, further comprising abrading or sanding a surface of said tape. 16. The method according to claim 14, further comprising abrading or sanding a surface of said tape prior to said bonding. 17. The method according to claim 14, wherein the tape has a pH of 1.0 to 6.9. 18. A composition comprising, wallboard or gypsum board;joint compound; andwallboard joint tape comprising a web of cellulosic fibers;at least one antimicrobial compound;at least one acid-based sizing agent; andoptionally starch; whereinpolyvinyl alcohol is not present;the antimicrobial compound is present at an amount ranging from about 10 ppm to about 5,000 ppm;the sizing agent comprises a combination of alum and rosin-based sizing agent and is present at an amount ranging from about 0.5 to about 1.5 wt %; andthe starch is present at an amount ranging from 0.0% to not more than about 5%. 19. The method according to claim 7, further comprising bonding the tape to a wallboard with joint compound, and finishing. 20. The method according to claim 19, wherein said wallboard tape reduces, inhibits, prevents, stalls, and/or retards the growth of mold or fungus on said wallboard. 21. The method according to claim 7, wherein said contacting occurs by spraying the said starch, sizing agent, and/or antimicrobial compound directly onto at least one surface of the web. 22. The composition according to claim 18, wherein the tape has a pH of 1.0 to 6.9.
