Abstract

A stair protection device includes a protection sheet having a first riser protection portion, a tread protection portion, and a second riser protection portion. The protection sheet also has at least one slit in the tread protection portion, a first score in the protection sheet between the first riser protection portion and the tread protection portion, and a second score in the protection sheet between the second riser protection portion and the tread protection portion. The protection sheet can be secured to a stair by adhering tape on a top of the tread protection portion over the at least one slit such that at least a portion of the tape passes through the at least one slit and adheres to a tread of the stair.

Claims (30)

1. A stair protection device comprising:

a protection sheet having a first riser protection portion, a tread protection portion, and a second riser protection portion;

at least one slit in the tread protection portion;

a first score in the protection sheet between the first riser protection portion and the tread protection portion; and

a second score in the protection sheet between the second riser protection portion and the tread protection portion;

wherein the protection sheet is configured to be secured on a stair with the tread protection portion on a tread of the stair, the first riser protection portion on a riser of the stair, and the second riser protection portion on a riser of a subsequent stair, by adhering tape on a top of the tread protection portion over the at least one slit such that at least a portion of the tape passes through the at least one slit and adheres to the tread of the stair.

2. The stair protection device of claim 1 , wherein the first riser section comprises a plurality of scores.

3. The stair protection device of claim 2 , wherein the plurality of scores are configured to be bent around a nosing of the stair such that a portion of the first riser protection portion reaches the riser of the stair.

4. The stair protection device of claim 1 , wherein the at least one slit comprises two slits, and wherein a first dimension of each of the two slits is greater than a second dimension of each of the two slits.

5. The stair protection device of claim 1 , wherein the at least one slit comprises one slit, and wherein a first dimension of the one slit is greater than a second dimension of the one slit.

6. A method of protecting a stair, the method comprising:

bending a protection sheet from an unfolded state to a folded state, wherein bending the protection sheet comprises bending the protection sheet at a first score of the protection sheet between a first riser protection portion of the protection sheet and a tread protection portion of the protection sheet, and bending the protection sheet at a second score between a second riser protection portion of the protection sheet and the tread protection portion of the protection sheet;

placing the protection sheet on a stair with the tread protection portion on a tread of the stair, the first riser protection portion on a riser of the stair, and the second riser protection portion on a riser of a subsequent stair; and

securing the protection sheet to the stair by adhering tape on a top of the tread protection portion over at least one slit in the tread protection portion such that at least a portion of the tape passes through the at least one slit and adheres to the tread of the stair.

7. The method of claim 6 , further comprising:

taping sides of the tread protection portion to the tread of the stair.

8. The method of claim 6 , further comprising:

taping the first riser protection portion to one or more of the riser of the stair or a second riser protection portion of a second protection sheet.

9. The method of claim 6 , further comprising:

taping the second riser protection portion to one or more of the riser of the subsequent stair or a first riser protection portion of a second protection sheet.

10. The method of claim 6 , further comprising:

bending a plurality of scores in the first riser section; and

placing a portion of the first riser section that includes at least some of the plurality of scores around a nosing of the stair.

11. A method of protecting a surface having multiple corners, the method comprising:

bending a protection sheet from an unfolded state to a folded state, wherein bending the protection sheet comprises bending the protection sheet at a first score of the protection sheet between a first portion of the protection sheet and a second portion of the protection sheet, and bending the protection sheet at a second score between the second portion of the protection sheet and a third portion of the protection sheet;

placing the protection sheet on a first surface with the first portion on the first surface and the third portion over a portion of a second surface; and

securing the protection sheet to the surface by adhering tape on a top of the first portion over at least one slit in the first portion such that at least a portion of the tape passes through the at least one slit and adheres to the first surface.

12. The method of claim 11 , wherein the first surface comprises a countertop, wherein the second surface comprises at least one cabinet.

13. The method of claim 11 , further comprising:

securing the protection sheet to another protection sheet that has been secured to the first surface.
