Taping & masking materials

Masking Tapes

Masking tapes are produced in various grades. Review tape manufacturers’ recommendations and then make your selection based on your working conditions and technique. A minimum requirement is tape designed for use with urethane and epoxy coatings.

Common problems with tapes not designed for use with these types of coatings are poor solvent resistance, creeping, adhesive residue remaining on the surface and poor moisture resistance.

For striping, a thin plastic tape such as 3M Fine Line® #218 is recommended. Pushing the edge of the tape to be painted down with fine sandpaper, a green Scotch-Brite® pad and/or a plastic spreader will help ensure a sealed edge and a fine, even, no creep line.

Masking Paper

Masking papers are manufactured in various grades. The solvents in urethane and epoxy coatings require a paper with excellent resistance to solvent penetration. 3M’s Scotchblok® Masking Paper is highly recommended.

Warning

  1. Do not use lightweight plastic masking materials that ‘cling’ to the surface. This can leave tracks or marks on the paint film which cannot be removed.
  2. Do not use plastic sheeting on a surface longer than two days. Condensation can form under the plastic causing blistering, bubbling or loss of gloss in the paint finish.
  3. Do not use newsprint or newspapers; these can stain the paint finish.
