Designed for mixed media, it supports a wide range of techniques including etching and reworking, while being eco-friendly and handcrafted in the USA for lasting durability and professional presentation. ## Description Ampersand’s Museum Series Claybord is the only professional painting panel made with a true kaolin clay ground—a smooth, absorbent, clay-coated painting surface inspired by the clay-gesso panels used by Renaissance artists. This ultra-refined ground offers crisp detail, clean color, and exceptional control for fine artwork on panel, mixed media, and experimental techniques. Unlike other art surfaces, Claybord supports both additive and subtractive approaches—its kaolin clay coating absorbs color beautifully while allowing artists to use scratchboard tools to etch and scratch in fine detail, or to lighten, refine, or even erase areas using oil-free steel wool or fine sandpaper.This flexibility gives artists a unique level of control across a wide range of media, including acrylics, inks, alcohol inks, gouache, egg tempera, casein, watercolor, graphite, airbrush, collage, image transfers, printmaking, and mixed media. The smooth, archival surface also supports mounting photographs, art prints, and other paper artwork, making it an exceptionally versatile rigid painting surface. Every Claybord panel is built on Ampersand’s premium, warp-resistant Hardbord™ core, the most stable wood substrate on the market, and sealed with Archiva-Seal™ to protect against Support-Induced Discoloration (SID). The result is an archival, durable surface suitable for professional work, detailed illustration, painting on panel, and complex mixed media techniques. Claybord is available in a 1/8"" flat profile and in 13-ply birch plywood cradled profiles at 7/8"", 1½"", and 2"" depths. For elegant display options, Ampersand’s 7/8"" Floaterframe is designed to accommodate both the 1/8"" flat and 7/8"" cradled Claybord panels, while the 1½"" Floaterframe is a perfect fit for the 1½"" cradle. The 2"" cradle features an elegant, substantial profile that stands on its own as a statement piece without a frame. Handcrafted in the USA using FSC-certified materials. Review: desertcart NOT delivered at front door - These three clayboards are wonderful to paint on. I even did some scratching on one of them. Review: Absolutely Nice and Different - The ultra-smooth surface produces some interesting results. I've tried oil pastels, watercolor, acrylic and water-based paint on them. Pastels and water-based seem to work the best for me. Unlike, say a glazed tile (also smooth), this board is extra-absorbent so the media immediately finds purchase and won't run (as in a glazed tile). Also, unlike canvas the surface will not deteriorate with steel wool, painting knife and the like. Only the paint is affected. Water-based can be manipulated after-the-fact by applying water. Kinda like oils that remain unset for a while. However, oil will dry much sooner on this board than in canvas. It is very similar to Formica (I haven't tried in Formica yet). However, due to its reasonable price and the frame's fit and finish this is worth it, in my opinion. Finally, the variety of sizes and widths makes it easier for the artist. ## Features - Unique Kaolin Clay Surface: The only professional painting panel with a true kaolin clay ground. Claybord’s ultra-smooth, absorbent surface delivers crisp detail, clean color, and a painting experience unmatched by canvas, paper, or traditional gessoed panels. - Etch, Erase & Refine: The clay coating allows artists to etch into the surface using scratchboard tools, knives, or craft blades to create sharp contrast, texture, and fine detail. You can also lighten, refine, or erase areas with oil-free steel wool or fine sandpaper for a level of control not possible on other painting surfaces. - Versatile Surface: Ideal for acrylics, inks, alcohol inks, gouache, egg tempera, casein, graphite, airbrush, collage, image transfers, and printmaking. The smooth, acid-free, archival clay surface also works beautifully for mounting photographs, art prints, and other paper artwork. - Go Beyond Canvas or Paper: Claybord supports creative possibilities other surfaces can’t, bringing mixed media, layering, etching, erasing, and subtractive techniques together on a single panel. A smooth, responsive surface for artists who want greater control and sharper detail. - Made in the USA: Constructed on Ampersand’s premium Hardbord and sealed with Archiva-Seal to protect against Support-Induced Discoloration (SID). The panel is archival, warp-resistant, and engineered to provide a stable, long-lasting painting surface. Proudly handcrafted in the USA using FSC-Certified materials. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005JJV9ZC | | Best Sellers Rank | #16,594 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #1 in Clayboard | | Brand | Ampersand Art Supply | | Brand Name | Ampersand Art Supply | | Color | 1/8" Flat Profile | | Customer Reviews | 4.5 out of 5 stars 625 Reviews | | Item Dimensions L x W | 36"L x 18"W | | Item Highlight | Kaolin Clay Painting Panel for Acrylic, Ink, Watercolor & Mixed Media | Ultra-Smooth, Reworkable Surface | | Item Type Name | Museum Series Claybord | | Item Weight | 2.2 pounds | | Manufacturer | Ampersand Art Supply | | Manufacturer Part Number | CBS18L | | Material | Wood, Kaolin Clay | | Material Type | Wood, Kaolin Clay | | Model Number | CBS18L | | Number of Items | 1 | | Paint Type | Watercolor | | Product Dimensions | 36"L x 18"W | | Size | 18" x 36" | | UPC | 707310011831 | | Unit Count | 1 Count | | Warranty Description | No Warranty | ## Product Details - **Brand:** Ampersand Art Supply - **Color:** 1/8" Flat Profile - **Material:** Wood, Kaolin Clay - **Item Weight:** 2.2 Pounds - **Product Dimensions:** 36"L x 18"W ## Images ![Ampersand Claybord | 18x36 | 1/8" Flat | Ink & Acrylic Painting Panel - Image 1](https://m.media-amazon.com/images/I/61WGEg6p2gL.jpg) ![Ampersand Claybord | 18x36 | 1/8" Flat | Ink & Acrylic Painting Panel - Image 2](https://m.media-amazon.com/images/I/81o035mpB8L.jpg) ![Ampersand Claybord | 18x36 | 1/8" Flat | Ink & Acrylic Painting Panel - Image 3](https://m.media-amazon.com/images/I/71YCQVZGeUL.jpg) ![Ampersand Claybord | 18x36 | 1/8" Flat | Ink & Acrylic Painting Panel - Image 4](https://m.media-amazon.com/images/I/81ksHUxo9yL.jpg) ![Ampersand Claybord | 18x36 | 1/8" Flat | Ink & Acrylic Painting Panel - Image 5](https://m.media-amazon.com/images/I/71gq0S6bx4L.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazon NOT delivered at front door *by S***N on October 5, 2026* These three clayboards are wonderful to paint on.

I use watercolors, and I love the smooth texture (makes smooth colors, too). They’re a good thickness for the size, but I did receive mine with a couple slightly dented corners. That wasn’t a big deal for me as I’m just experimenting. I will order them again, probably in a bigger pack which will be cheaper and (hopefully) less likely to arrive without damage. I appreciate the price point, too. —One note, I’ve heard in a few places that you can wash these off and paint on them more than once. This is definitely not true of watercolor paints. The clay is porous and will stain. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/42320585-ampersand-claybord-18x36-1-8-flat-ink-and-acrylic-painting](https://www.desertcart.us/products/42320585-ampersand-claybord-18x36-1-8-flat-ink-and-acrylic-painting) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-10-26*
