Gobi Rammed Earth Board Installation Process: Step-by-Step Real Photos

1. Planning & Material Prep: Setting the Stage for Success

Before you even touch a trowel or saw, take time to plan. Rammed earth panels, especially the Gobi variant, have subtle color variations—think soft terracottas, warm beiges, and hints of desert gold—that make each piece unique. Lay out all your panels on a flat surface first (a clean garage floor or large tarp works) to arrange them like a puzzle. This way, you can balance light and dark tones, ensuring no single area feels too uniform. It's like curating a gallery wall, but with stone.

Materials You'll Need (Checklist)

Pro tip: If your wall adjoins fair-faced concrete or wood grain board , bring a sample of those materials to the supplier. They can help you pick Gobi panels that complement—not clash with—existing textures. For example, pairing Gobi's warmth with the cool gray of fair-faced concrete creates a striking, balanced contrast.

2. Surface Preparation: The Foundation Matters

Rammed earth panels are heavy—each 2x4ft Gobi board can weigh 25-30 lbs—so the surface they're attached to needs to be rock-solid. Start by inspecting your wall: is it drywall, concrete, or wood studs? Each requires slightly different prep.

For Drywall or Plaster Walls

If you're working with drywall, first check for loose seams or cracks. Fill any gaps with spackle, let it dry, then sand smooth. Next, apply a coat of primer-sealer designed for masonry. This helps the adhesive bond better and prevents moisture from seeping into the drywall. Think of it as a "primer hug" for your wall—it needs to hold tight.

For Concrete or Block Walls

Concrete is sturdy, but it can be dusty. Use a stiff brush or shop vac to remove debris, then wipe with a damp cloth. If the surface is uneven (common with older concrete), use a leveling compound to fill low spots. Let it cure fully—at least 24 hours—before moving on. You want the wall as flat as a tabletop; even a 1/8" dip can make panels sit crooked.

3. Cutting & Fitting: Precision = Beauty

No wall is perfectly square, and doors, windows, or outlets will mean cutting panels to size. The Gobi Rammed Earth Board is dense, so a standard wood saw won't cut it (pun intended). Use a circular saw with a diamond-tipped masonry blade—this will slice through the panel cleanly without chipping the edges.

Step-by-Step Cutting

1. Measure twice, cut once: Mark the panel with a pencil and straightedge. Add 1/16" to your measurement to leave room for grout later.
2. Clamp it down: Secure the panel to a workbench with C-clamps to prevent slipping. Cover the cut line with painter's tape to reduce chipping—this trick works wonders for keeping edges sharp.
3. Saw slowly: Let the blade do the work. Pushing too hard can cause the panel to crack. Aim for a steady, 2-3 inch per second pace.
4. Smooth the edges: Use 80-grit sandpaper to gently round sharp corners. The goal isn't to polish—just to remove any rough spots that might catch on adjacent panels.

Pro tip: Save your cutoffs! Small scraps can be perfect for filling gaps around outlets or tight corners. It's like using leftover dough to patch a pie crust—resourceful and zero waste.

4. Adhesive Application: Sticking It Right

The adhesive is the glue (literally) that holds your wall together. For Gobi Rammed Earth Boards, we recommend a polymer-modified mortar adhesive—think of it as supercharged glue for stone. It's stronger than regular construction adhesive and flexible enough to handle tiny shifts in the wall (like seasonal expansion) without cracking.

How to Apply Adhesive Like a Pro

Load your notched trowel with adhesive and spread it evenly over the back of the panel. Hold the trowel at a 45-degree angle to create ridges—these ridges collapse when you press the panel against the wall, ensuring full contact. Cover the entire back, but leave a 1/4" border around the edges to prevent adhesive from oozing out during installation (no one wants "adhesive acne" on their new wall).

5. Panel Installation: Bringing the Gobi to Life

Now comes the satisfying part: placing the first panel. Start at the bottom left corner (or bottom right, if you're left-handed—whatever feels natural). Press the panel firmly against the wall, wiggling it slightly side-to-side to ensure the adhesive makes good contact. Use a level to check for plumb (vertical straightness) and adjust as needed—even a tiny tilt will throw off the entire row above.

Spacing & Alignment

Leave a 1/8" gap between panels for grout. Use plastic spacers (available at hardware stores) to keep this consistent—they're cheap insurance against wonky lines. For the next panel, repeat the process: apply adhesive, press, level, spacer. Stagger the seams like brickwork (offsetting each row by half a panel) to add strength and visual interest. It's the difference between a wall that looks "put together" and one that looks "crafted."

As you work your way up, periodically step back and check the big picture. Does the color flow? Are the gaps even? This is where that earlier layout photo comes in handy—compare the wall to the photo to stay on track.

6. Grouting & Finishing: The Final Touch

Once all panels are installed and the adhesive has cured (follow the manufacturer's instructions—usually 24-48 hours), it's time to grout. Choose a grout color that complements the Gobi panels: sanded beige or light gray works well to keep the focus on the stone, while a darker gray can add contrast. Mix the grout to a "peanut butter" consistency—thick enough to hold a shape, but not so thick it clumps.

Grouting Steps

1. Apply with a float: Scoop grout onto a rubber float and press it into the gaps at a 45-degree angle. Work in small sections (3x3ft) to prevent the grout from drying out.
2. Clean excess: After 10-15 minutes, use a damp (not soaking) sponge to wipe away excess grout. Rinse the sponge frequently to avoid smearing. The goal is a smooth, even joint—not a perfect one; slight imperfections add character.
3. Buff the surface: Once the grout is fully dry (24 hours), use a dry microfiber cloth to buff away any haze. This reveals the panel's natural sheen—suddenly, the texture pops, and the wall feels alive.

7. Sealing: Protecting Your Investment

Rammed earth is porous, so sealing is non-negotiable—especially in high-traffic areas or rooms with moisture (like kitchens or bathrooms). Choose a water-based stone sealer designed for porous materials. Apply it with a foam brush in thin, even coats, letting each coat dry completely (about 2 hours) before adding another. Two coats should be enough for most indoor walls; for outdoor use (yes, Gobi panels work outside!), add a third.

8. Final Inspection: Admire, Adjust, Enjoy

Step back, turn on the lights, and take it all in. Run your hand over the surface—the texture should feel smooth but substantial, like running your palm over sun-warmed sand. Check for any loose panels (gently tug—they shouldn't move), uneven grout lines, or missed spots in the sealer. Fix small issues now, and you'll avoid bigger headaches later.

And then? Enjoy it. The Gobi Rammed Earth Board isn't just a wall covering—it's a piece of the outdoors, brought inside. Whether you've used it in a living room, bedroom, or commercial space, it will age beautifully, developing a patina that tells the story of the life lived around it. That's the magic of natural materials: they don't just decorate a space—they become part of it.
