A smudge of camouflage earth coat on a plain light gray background.

Earth Coat is a natural slurry that softens its surroundings with the time-worn finish of stone plaster. Imbued with a fine, tactile grain, Earth Coat imparts depth and character to walls made of concrete, brick, stucco, or fencing. May be used for both indoor and outdoor applications.

Earth Coat is offered in three distinctive colors that draw from the landscape itself. Canvas is a warm neutral that frames greenery with softened contrast, while Camouflage, an earthy green, acts as an extension, blurring the lines of the garden's expanse. Dusk’s soft black hue underscores the forms and color palette of the surrounding foliage.

The sample pot contains a 1 oz. dry mineral mix for testing on your desired surface.

FAQ

What is Earth Coat?

Earth Coat is a mineral-based slurry that creates a durable, breathable finish for interior and exterior surfaces. Made from natural mineral ingredients, it develops a rich, matte texture that allows substrates to breathe while aging beautifully over time.

What surfaces can Earth Coat be applied to?

Earth Coat can be applied directly to untreated, unsealed mineral substrates including: brick, CMU (concrete masonry units), concrete, cement plaster, stucco, natural stone, and other absorbent masonry surfaces. For previously painted, sealed, or treated surfaces, a compatible bonding primer is recommended before application.

Can Earth Coat be used indoors and outdoors?

Yes. Earth Coat is designed for both interior and exterior applications, making it suitable for garden walls, fireplaces, feature walls, facades, retaining walls, and other masonry surfaces.

Does Earth Coat work in humid or freezing climates?

Yes. Once fully cured, Earth Coat performs well across a range of climates, including humid and freeze-thaw environments. Because it is vapor permeable, it allows moisture to escape rather than becoming trapped behind the coating, helping support the long-term performance of mineral masonry substrates.For best results, apply only when air and surface temperatures are between 41°F and 93°F (5°C–34°C), and avoid application during rain or freezing conditions while the coating is curing.

Is a primer required?

No primer is needed for most unpainted, absorbent masonry surfaces such as brick, stone, concrete, or stucco. If the surface has previously been painted, sealed, or treated, we recommend applying a mineral-compatible bonding primer before Earth Coat.

How should I apply Earth Coat?

We recommend using a limestone brush for a textured and earthen finish. You may also use a roller or trowel. For more information around application, view our guide here.

How do I mix the Earth Coat powder?

Slowly add water to the dry mix, making sure to not add too much water. The consistency of the finished Earth Coat should be slightly thicker than the consistency of a paint.

What kind of finish does Earth Coat create?

Earth Coat creates a soft, mineral-rich matte finish with natural variation. It can be applied smoothly for a refined appearance or more heavily for a textured, timeworn character.

How much Earth Coat do I need?

5 Gallon | 32 lbs. will cover approximately 150 to 200 sq ft in 1 coat, depending on the desired thickness, application method, and the type of substrate.

Can Earth Coat be applied to pathways?

We do not recommend using Earth Coat on pathways or any places with high foot traffic.
