Finishing Design-Cast 62

You can patch the surface of hardened DC-62 with some freshly mixed material. First roughen the area to be patched by coarse sanding or grinding, and then thoroughly saturate the area with water. For best results, patch the piece as soon as possible after it has hardened. After patching, you must keep the piece wet for 24 hours to allow the patch to harden fully.

You can grind or polish hardened DESIGN-CAST surfaces using abrasive tools or papers. Note: do not metal tools, since metals are not as hard as DESIGN-CAST.

You can apply different kinds of coatings to DESIGN-CAST surfaces with excellent adhesion. Water, oil- and solvent-based materials all work well. If you use anything other than a water-based coating, you must let the piece dry thoroughly first. In general, breathable type coatings are recommended such as water-base acrylics.

DESIGN-CAST sealers AA-6 (matte) or AA-7 (gloss) are recommended when you want a clear and colorless protective coating. Either of these sealers also makes an excellent patina base for the addition of tinting colors, such as the ‘Universal’ pigments used for paints.

A variety of patina coatings can be obtained from the suppliers listed on our Sources page.
