About the Wallpaper

Clay Coated is a dimensionally stable non-woven wallcovering with a traditional clay coating engineered to enhance the surface and provide a dead-flat matte finish with a subtle vellum texture. Providing exceptional color and crisp, clean imaging on a soft white surface, resulting in a true matte aesthetic ideal for high-end interior applications.

Professional installation is recommended.

Confirm the Product

Verify pattern, texture, scale, color matching of panels, and the printed surface is free from defects before cutting. no returns on cut material. If you see any issues, please contact support@baxtermillarchive.com.

Allow the material to reach room temperature before handling and store in a clean, dry, temperature-controlled environment.

Other Instructions

Allow 24–48 hours for the primer to dry before continuing.

Walls must be completely free of mold, mildew, or residue prior to application. The building must be weather-tight, with HVAC systems operational before, during, and after installation. Acceptable environmental conditions: 65–85°F (18–29°C) and 40–60% relative humidity.

Do not crease the material before or during installation, as the creases may not disappear.

Surface Preparation

1. Smooth the Wall

• Measure and inspect walls to ensure they are smooth and that you have the correct amount of product.
• Correct any deficiencies before installing.
• Remove protruding nails and fill holes, cracks, or indentations with acrylic spackling paste, then sand smooth.

2. Wash the Wall

• Clean the surface to remove dust, dirt, mold, mildew, and stains.
• Use a mixture of warm water and vinegar with a damp microfiber cloth or sponge.
• Ensure the wall is completely dry before continuing.

3. Apply a Primer

• A fresh coat of primer ensures a strong bond between the wall and wallpaper.

Planning the Installation

• Measure walls a second time before starting.
• Plan pattern placement and drop match to ensure symmetry or alignment of graphics.
• Shut off power to wall switches/outlets and remove switch plates.
• Use a level or plumb bob to draw a straight line as a guide for the first panel.

Adhesive Application

• Use a high-quality adhesive suitable for your wall type and wallcovering (see recommendation above).

Pasting Process

1. Lay the panel on a clean table or pasting board.
2. Roll adhesive onto the upper half of the panel.
3. Gently fold pasted surface onto itself (avoid hard creases).
4. Rotate, paste the bottom half, and fold.
5. Once fully pasted, fold toward the center and allow to “book” for up to 10 minutes before hanging.

Installation

1. Open the top fold of the booked wallpaper and position the panel at the top of the wall, leaving approximately 2" of excess material at the ceiling for trimming. 
2. Working from top to bottom, apply the panel to the wall while aligning the edge with your plumb line. Gradually unfold the lower portion of the panel as needed during installation.
3. Using a wallpaper smoother, gently remove wrinkles and air bubbles, continuing to work from the top down.
4. Trim excess material at the ceiling and baseboard with a sharp utility knife, then smooth the cut edges firmly against the wall. Remove any excess adhesive immediately with a clean, damp sponge and fresh water. 
5. Measure and cut the next panel, allowing for proper pattern matching before installation.
6. Install the second panel using the same method, overlapping it onto the first panel while carefully matching the pattern from top to bottom. Reposition as needed for precise alignment. Continue installation in one consistent direction, either left to right or right to left, throughout the project.
7. Once the overlapping panel is aligned and in place, position a straightedge at the center of the overlap and use a sharp utility knife to cut through both layers from top to bottom. This double-cut method helps achieve accurate pattern alignment and a professional finish. 
8. Carefully remove the narrow-cut strips from both layers, then smooth the seam firmly against the wall to create a clean, seamless appearance. 
9. Repeat this process for each additional panel until installation is complete.
