About Paint and Protective Coatings

These thin primers penetrate deeply into concrete floors to create a hard surface that can then be coated with any urethane or epoxy coating. Primers resist abrasion and chemicals, such as mild acids, alkalies, salt, and fuel. Apply with a roller. The size listed is the combined total of the two parts.

Smoothing and Protective Coatings for 3D-Printed Plastics

Unlike other processes that remove surface ridges on 3D-printed parts, these coatings hide them for a smooth, glossy, heat- and impact-resistant finish. Mix this two-part coating and apply it to your parts—a small amount will cover a lot. The coating spreads uniformly without leaving stroke marks, making parts smooth enough to use as a mold, or they can be sanded, primed, or painted for further finishing work.

To add color to your parts without the extra step of painting, stir a few drops of UV-resistant pigments (sold separately) into your coating mixture. The pigments are UV-stable, which keeps the color from fading, warping, or cracking when exposed to sunlight.

Epoxy Grout

Mix this two-part epoxy—a resin-aggregate blend and a pigmented hardener—to create a grout that resists chemicals, such as acids, alkalies, salt water, and common solvents and cleaners. Its lightweight formula makes this grout easy to spread. Use in horizontal or vertical joints—grout won’t sag or shrink. Apply with a grout float. It can be cleaned up with water when wet; it doesn’t require a sealer once it cures. The size listed is the combined total of the two parts.

Drywall Crack Fillers

Fix cracks in drywall and stop them from spreading. Place the included fabric over wall cracks and cover with the acrylic paste. This results in a flexible, nonshrinking repair that prevents cracks from reappearing as the building continues to settle.
