Floor finish application pad and method
View Patent ↗A floor finish application apparatus and method for applying floor finishes to a floor. The floor finish application apparatus can include an applicator pad, which in some embodiments comprises filter material. In some embodiments, the filter material is air filter material, and has certain wet and/or dry friction characteristics, density, thickness, compressive resistance, liquid absorptive capacity, porosity, spreading capability, and/or leveling capability. In some embodiments, the pad has a stepped or otherwise uneven height.
1. A floor finish applicator pad, comprising:
a leading edge;
a trailing edge; and
a sheet having
a first side;
a second side opposite the first side and more fluid absorbent than the first side; and
a fold at least partially defining one of the leading and trailing edges of the applicator pad and having at least a double layer of the sheet, the fold further defining a first portion of the applicator pad in which the second side of the sheet is oriented to engage a floor surface;
wherein a second portion of the applicator pad is at least partially defined by the sheet, the first side of the sheet at the second portion oriented to engage the floor surface.
2. The floor finish applicator pad of claim 1 , wherein the second side of the sheet is more fluid permeable than the first side.
3. The floor finish applicator pad of claim 1 , wherein the first side of the sheet is smoother than the second side.
4. The floor finish applicator pad of claim 1 , wherein the sheet is folded upon itself at the leading edge of the applicator pad to define a thickness of the leading edge that is greater than that of the trailing edge.
5. The floor finish applicator pad of claim 1 , wherein:
the first side of the sheet is oriented to engage the floor surface is proximate the trailing edge of the applicator pad; and
the second side of the sheet is oriented to engage the floor surface is proximate the leading edge of the applicator pad.
6. The floor finish applicator pad of claim 1 , wherein the sheet is a first sheet, the applicator pad further comprising a second sheet partially enclosed by the first sheet, wherein the second sheet has a first side and a second side, and wherein the first side of the second sheet is opposite to and less fluid absorbent than the second side of sheet.
7. The floor finish applicator pad of claim 1 , wherein:
the applicator pad has opposite top and bottom surfaces; and
at least one of the top and bottom surfaces is stepped.
8. The floor finish applicator pad of claim 1 , wherein the static coefficient of friction of the sheet according to ASTM D-2047 using a 3×3 inch sample of the sheet applied against a 12×12 inch black vinyl composite tile is less than about 0.32.
9. The floor finish applicator pad of claim 1 , wherein the density of the sheet is greater than about 0.01 g/cm 3 and is less than about 0.08 g/cm 3 .
10. The floor finish applicator pad of claim 1 , wherein the sheet has a thickness greater than about 0.3 cm and less than about 2.5 cm.
11. The floor finish applicator pad of claim 1 , wherein the sheet has a liquid absorptive capacity according to INDA and EDANA WSP10.1(05) of at least about 500%.
12. The floor finish applicator pad of claim 1 , wherein the sheet comprises air filter material.
13. A floor finish applicator pad, comprising:
a body comprised of a sheet with a first side and a second side opposite the first side, the body having:
leading and trailing edges joined by lateral sides;
a ground-engaging surface; and
a fold at least partially defining one of the leading and trailing edges and having at least a double layer of the sheet such that at least a portion of each of the first side and the second side is oriented to engage a floor surface,
wherein the body comprises material having a density greater than about 0.01 g/cm 3 and less than about 0.08 g/cm 3 .
14. The floor finish applicator pad of claim 13 , wherein the fold defines a first portion of the body in which the second side is oriented to engage a floor surface, and wherein the body has a second portion at least partially defined by the first side oriented to engage the floor surface.
15. The floor finish applicator pad of claim 13 , wherein the body further comprises a thickness greater than about 0.3 cm and less than about 2.5 cm.
