What is claimed is: 1. A reinforcing tape, comprising: reinforcing yarns joined together to form an open fabric or scrim to define openings for passage of a joint compound, wherein the openings are bounded by the yarns; a first coating penetrating the yarns and adding tensile strength to the yarns
What is claimed is: 1. A reinforcing tape, comprising: reinforcing yarns joined together to form an open fabric or scrim to define openings for passage of a joint compound, wherein the openings are bounded by the yarns; a first coating penetrating the yarns and adding tensile strength to the yarns wherein, said first coating comprises a styrene-butadiene polymer or copolymer with a styrene concentration adjusted to about 60% or less to adjust suppleness of the tape; and a second coating on said first coating, the second coating adding resistance to pull out of the yarns from the joint compound. 2. The reinforcing tape of claim 1 wherein, the yarns include zero twist yarns. 3. A reinforcing tape, comprising: reinforcing yarns joined together to form an open fabric or scrim to define openings for passage of a joint compound, wherein the openings are bounded by the yarns; a first coating penetrating the yarns and adding tensile strength to the yarns; and a second coating on said first coating, the second coating adding resistance to pull out of the yarns from the joint compound wherein, the second coating comprises a functional coating of a solvent activated, phase changing adhesive; the phase changing adhesive changing to a liquid phase while in contact with solvent in a solidifiable joint compound; and the phase changing adhesive changing to a solid phase by solidifying together with the joint compound, thereby adhering the yarns to the solidified joint compound and resisting pull out of the yarns therefrom. 4. The reinforcing tape claim 1 wherein; the yarns are arranged in a plain weave of, twisted warp yarns and twisted weft yarns; the yarns have yarn counts of, not greater than 33 tex for one, and not greater than 66 tex for the other; the warp yarns and the weft yarns are interchangeable, one to the other; and the weave has a thickness of not greater than 0.18 mm. 5. The reinforcing tape of claim 1, further comprising: a pressure sensitive adhesive on at least a back side of the tape. 6. The reinforcing tape of claim 5, further comprising: a blocking agent at an outer surface of the tape. 7. A joint, comprising: a joint compound filling a wallboard seam; a reinforcing tape imbedded in the joint compound, the tape having reinforcing yarns that are interlaced to define openings for passage of the joint compound, wherein the openings are bounded by the yarns; a coating penetrating the yarns and adding tensile strength to the yarns; and another coating on said coating penetrating the yarns, said another coating being activated to an adhesive state by solvent in the joint compound, said another coating adding resistance to pull out of the yarns from the joint compound. 8. The joint of claim 7 wherein, the coating adding tensile strength comprises a styrene-butadiene polymer or copolymer with a styrene concentration adjusted to about 60% or less to adjust suppleness of the tape. 9. The joint of claim 7 wherein, the yarns include zero twist yarns. 10. The joint of claim 7 wherein; said another coating comprises a functional coating of a solvent activated, phase changing adhesive, the phase changing adhesive changing to a liquid phase while in contact with solvent in a solidifiable joint compound, and the phase changing adhesive changing to a solid phase by solidifying together with the joint compound, thereby adhering the yarns to the solidified joint compound and resisting pull out of the yarns therefrom. 11. The joint of claim 7 wherein; the yarns are arranged in a plain weave of, twisted warp yarns and twisted weft yarns, the yarns having yarn counts of, not greater than 33 tex for one, and not greater than 66 tex for the other, the warp yarns and the weft yarns being interchangeable, one to the other, the weave having a thickness of not greater than 0.18 mm. 12. The joint of claim 7, further comprising: a pressure sensitive adhesive on at least a back side of the tape. 13. The joint of claim 7, further comprising: a blocking agent at an outer surface of the tape. 14. The reinforcing tape of claim 3 wherein, the yarns include zero twist yarns. 15. The reinforcing tape of claim 3 wherein; the yarns are arranged in a plain weave of, twisted warp yarns and twisted weft yarns; the yarns have yarn counts of, not greater than 33 tex for one, and not greater than 66 tex for the other; the warp yarns and the weft yarns are interchangeable, one to the other; and the weave has a thickness of not greater than 0.18 mm. 16. The reinforcing tape of claim 3, further comprising: a pressure sensitive adhesive on at least a back side of the tape. 17. The reinforcing tape of claim 16, further comprising: a blocking agent at an outer surface of the tape.
