Abstract

A masking strip for masking the interior surfaces of a gap (8) between two substrates (2,3) to be painted is disclosed. The masking strip comprises a backing (10) having a first surface and a second surface. A gap filler (13) is also provided, extending from the backing (10) and adapted to prevent the flow of paint into the gap (8). The backing (10) is formed from, or attached to, a fibre—containing material that acts to wick paint away from the interior surface of the gap (8) to which the masking strip is fixed. Preferably the fibre—containing material is one of paper, tissue, a non-woven or a woven material.

Claims

1. Masking strip for masking the interior surfaces of a gap between a first substrate and a second substrate to be painted, comprising:

a backing having a first surface and a second surface, and

a gap filler extending from the backing and adapted to prevent the flow of paint into the gap;

wherein the backing is formed from, or attached to, a fibre-containing material that acts to wick paint away from the interior surface of the gap to which the masking strip is fixed.

2. Masking strip as claimed in claim 1, wherein the gap filler extends from the first surface or the second surface of the backing

3. Masking strip as claimed in claim 1, wherein the second surface of the backing carries an adhesive to fix the masking strip to an interior surface of the gap.

4. Masking strip as claimed in claim 1, wherein the strip further comprises a spacer attached to the second surface of the backing

5. Masking strip as claimed in claim 4, wherein the spacer is formed from the fibre-containing material

6. Masking strip as claimed in claim 4, wherein the spacer is a composite spacer comprising a base layer and a cover layer.

7. Masking strip as claimed in claim 6, wherein the cover layer is a fibre-containing material.

8. Masking strip as claimed in claim 1, wherein the fibre-containing material contains at least one of natural, cellulose or synthetic fibres.

9. Masking strip as claimed in claim 1, wherein the fibre-containing material comprises one of:

paper, tissue, woven material or non-woven material.

10. Masking strip as claimed in claim 9, wherein the paper material has a weight in the range 35 to 100 gsm.

11. Masking strip as claimed in claim 9, wherein the paper material is textured.

12. Masking strip as claimed in claim 9, wherein the tissue material has a weight in the range 10 to 35 gsm.

13. Masking strip as claimed in claim 1, wherein the fibre-containing material is perforated.

14. Masking strip as claimed in claim 1, wherein the gap filler comprises a foam material.
