Need to cut costs on your masking products?

While you can order masking supplies in any quantity with no minimum order requirement, we also offer bulk prices, helping you save even more.

In addition, if you are currently masking with caps and plugs, we offer a budget conscious alternative to silicone. EPDM is a more economical material that withstands temperatures up to 425F / 218C, holds up to multiple uses and has a superior chemical resistance.

We also offer low cost, single use soft vinyl or paper masking caps, as well as a large selection of paint masking tapes and discs. You may also be interested in our masking plugs for protecting female threads or prevent paint from entering an opening.
