In order to get the masking to stick properly you need a clean surface to apply it to. Blow off the material with an air compressor and to take it a step further, you could even use a tack cloth to ensure there are no dust specks left on the material.

ORAMASK 810, 811, and 813 are all 3 mil calendered films with low tack removable adhesives. 811 and 813 are for smooth, flat surfaces. Oracal designed 810 for flexible or uneven surfaces. You can buy it with a solvent based adhesive in the 810S version.

Developed for use in paint and stain stencil applications, especially for paint and spray techniques on smooth, flat, rigid substrates and surfaces. Applications requiring transparency of the paint mask for substrate visibility.
