Matte Green Iron Oxide Powder Concrete Pigment - 2.5 Lbs

In this review the Matte Green Iron Oxide Powder stands out as a versatile, affordable colorant for DIYers and small studios who need a consistent, earthy green for cement and related materials. The powder's biggest strength is its intended flexibility: it is formulated to dye cement, concrete, grout, mortar, stucco and similar mixes while also working in epoxy, resin and clay, making it practical for craft projects, mosaics and small-scale concrete work. For those seeking a matte, opaque finish and easy dispersion, this pigment delivers reliable results.

Key Features

• Multi-material use: The pigment is formulated to color cement, concrete, grout, render, mortar, stucco, plaster, putty and clay for a wide range of construction and craft applications.
• Craft and industrial friendly: It is suitable for ceramics, terrazzo, mosaics and planters and also for tinting epoxy, resin, varnish and wood fillers, giving makers flexibility across media.
• Intermixable colors: Sold in a matte, opaque finish and designed to be mixed with other shades to achieve a broader palette and warmer earthy tones.
• Durable formula: High-purity iron oxide provides consistent color and long-lasting performance in both interior and exterior applications.
• Easy dispersion: Fine particle size (500 mesh) and water-soluble properties help the powder blend into dry mixes and wet media with minimal clumping.
• Practical quantity and dosing: The 2.5 lb bag covers small to medium projects and a typical dosing guideline is 1 part colorant to 20 parts concrete by weight.

Who It's For

The pigment is best for hobbyists, small workshop makers and tradespeople who need a reliable green tint for concrete, grout, stucco or plaster projects and who appreciate a matte, earthy finish. It is also well suited to ceramic artists and anyone tinting epoxy, resin or wood fillers for decorative pieces or repairs.

It is less suitable for large commercial pours where bulk pigment procurement and batch control at industrial scale would be preferable, and those seeking glossy or translucent dyes should look to other colorant types rather than an opaque iron oxide powder.

Pros & Cons
