Abstract

A drywall tape including a fiber matrix having a first side and an opposing second side; a sandable coating on at least a portion of the first side of the fiber matrix, wherein the sandable coating is a first color; and, an adhesive element on at least a portion of the second side of the fiber matrix. Additionally, a system for preventing oversanding of surfaces including a matrix having a first side and an opposing second side; and, at least one sandable coating on at least a portion of the first side of the flexible matrix, wherein the sandable coating is a different color than the color of joint compound when dried.

Claims

1. A fiber matrix comprising:

the fiber matrix having a first side and an opposing second side;

a sandable coating on only and configured to remain above the fiber matrix wherein the sandable coating comprises a first dye;

wherein the sandable coating provides an indicator above the matrix for preventing sanding of the fibers; and

,

an adhesive element on at least a portion of the second side of the fiber matrix.

2. The fiber matrix of claim 1, wherein the fiber matrix comprises a second dye different than the first dye of the sandable coating.

3. The fiber matrix of claim 1, wherein the fiber matrix is arranged in a biaxial orientation, a triaxial orientation, a quadriaxial orientation or any combination thereof.

4. The fiber matrix of claim 1;

wherein the fiber matrix comprises flexible properties.

5. The fiber matrix of claim 1, wherein the fiber matrix includes a glass fiber, a carbon fiber, a basalt fiber, an aramid fiber, a polyolefin fiber, a synthetic polymer fiber, a plant-product-based fiber, an animal-product-based fiber, or any combinations thereof.

6. The fiber matrix of claim 1;

wherein the tape further includes a removable backing for covering the adhesive layer.

7. The fiber matrix of claim 1, wherein the adhesive element is a pressure sensitive adhesive.

8. The fiber matrix of claim 1, wherein the sandable coating comprises properties such that it may be removed using sandpaper.

9. A drywall repair patch for providing a smooth surface for painting, the repair patch comprising:

the fiber matrix having a first side and an opposing second side;

a sandable coating on only and configured to remain above the fiber matrix, wherein the sandable coating comprises a first layer having a first dye and a second layer having a second dye;

wherein the sandable coating provides an indicator above the matrix when interacting with joint compound for preventing sanding of the fibers; and

,

an adhesive element on at least a portion of the second side of the fiber matrix.

10. The drywall repair patch of claim 9, wherein at least a substantial portion of the second layer is outwardly situated relative to the first layer.

11. The drywall repair patch of claim 9, wherein the fiber matrix is arranged in a biaxial orientation, a triaxial orientation, a quadriaxial orientation or any combination thereof.

12. The drywall repair patch of claim 9, wherein the fiber matrix comprises flexible properties.

13. The drywall repair patch of claim 9, wherein the fiber matrix includes a glass fiber, a carbon fiber, a basalt fiber, an aramid fiber, a polyolefin fiber, a synthetic polymer fiber, a plant-product-based fiber, an animal-product-based fiber, or any combinations thereof.

14. The drywall repair patch of claim 9, wherein the tape further includes a removable backing for covering the adhesive layer.

15. The drywall repair patch of claim 9, wherein the adhesive element is a pressure sensitive adhesive.

16. The drywall repair patch of claim 9, wherein the sandable coating comprises properties such that the first and second layers may be removed using sandpaper.
