Aquabord overview

Aquabord is an acid-free, textured coated hardboard panel that gives watercolorists unprecedented freedom and control. The surface absorbs watercolors like a fine cold press paper, allowing you to create washes and stack glazes. Painting on Aquabord is a joy since the surface is responsive and cooperative, allowing the paint to move freely and blend beautifully. It is perfect for watercolors and gouache but is also ideal for casein and acrylics.

This museum quality panel has a lovely eggshell color and a soft, absorbent, mineral coating with a unique granular texture. Although it uses kaolin clay as its base, its formulation makes it more absorbent than our Claybord surface. The Aquabord surface has a subtle tooth that is evident in the finished work. The texture, however, is finer than that of a rough or cold press paper, creating fewer shadows on the surface. The bright reflective quality of the white clay allows colors to remain pure and radiant. The surface allows color to be lifted back to white easily while also leaving the richest, most vibrant color possible.



Ampersand’s panels are truly archival. Every Aquabord panel receives our patented Archiva-Seal™ coating, the most advanced formula for sealing wood that prevents support induced discoloration. Because Aquabord’s Hardbord substrate has been properly sealed, your work will remain acid-free. Aquabord is available as a 1/8" flat panel or with 7/8", 1.5", and 2" cradle profiles. It has a wide range of standard sizes from 4x4 up to 24x36. Ampersand 1/8" flat panels and cradled 7/8" and 1.5" fit in our Floaterframes. Only Ampersand builds their cradles by hand with premium-grade 13-ply birch plywood for maximum stability and a clean, finished look from edge to edge. Cradles can be painted or stained to complement the artwork or sealed and then primed with gesso to wrap your image around the edges. For ideas on how to treat the edges of the cradle, consult this article. Aquabord panels are eco-friendly, and proudly handcrafted in the USA, just south of Austin in Buda, Texas.


  • Watercolors and gouache are noticeably richer on Aquabord. Colors retain their purity and vibrancy in a way that even the finest of watercolor papers can never match. Previously, the watercolorist accepted a loss of brilliance in some colors as the pigment was absorbed into the depths of the paper.
  • The Aquabord surface simulates the absorbency and texture of standard cold pressed watercolor paper, without its limitations.
    • Will not tear, shrink, or buckle even under heavy water application.
    • The surface is very forgiving and durable and will hold up to repeated wetting and lifting.
    • The flawless pebbly surface of Aquabord takes layers and layers of pigment without wearing down.
    • You can paint as heavily as desired because Aquabord won’t warp, crack, or bend like paper when using heavy paint applications.
    • There is no need to worry about lint residue, torn paper, or using masking fluid.
  • On the Aquabord surface, you can easily accomplish many of the more difficult watercolor effects created on paper.
    • The sponge-like granules absorb the water and pigment allowing incredible control over color, washes, and glazes.
    • The surface’s clay-base holds colors in suspension, allowing them to flow into each other to create seamless washes when the board is wet or dry.
    • The surface allows the painter to create the softest washes, typical of those possible on cold press papers, as well as vibrant colors and textured patterns that are possible on hot press paper or bristol board.
  • The surface of the Aquabord permits the careful lifting of layers of pigment value and hues to those colors below, bringing out sparkling underpainting for emphasis and contrast.
    • Aquabord is very forgiving.
    • Color can be lifted back to the white of the surface.
  • Aquabord is eco-friendly and made in Buda, Texas (just outside of Austin) from US-grown renewable wood sources. The wood used to manufacture Aquabord, like all of Ampersand’s Museum Series panels, is FSC-certified.
  • Aquabord is archival, pH neutral, and acid-free.
  • When you are finished, you can present the painting without glass.


Tips and Techniques:


You can paint on the Aquabord surface when it is either wet or dry. To get rich, vibrant color and to make it easier to lift colors off, use watercolors in a heavier consistency more like skim milk, for example. For crisp edges and sharp details, mix less water with your paint and apply it onto a dry Aquabord surface. It is not necessary to wash the entire surface of the board with water, but rather you can choose to work in smaller areas. When wet, the natural surface darkens to a light taupe. This value change easily allows the painter to know which areas are wet and which are dry as the work progresses. The bright white color of the clay returns when the board dries completely.


You may notice small "pin-like" protrusions once you lay down your washes and you may also see tiny bubbles forming on the surface. This is normal. For smooth, even washes, it’s a good idea to first "flush out" the surface of the Aquabord panel before beginning by simply applying an even wash of water with a large brush over the area in which you are working to release trapped air. By allowing the air to escape first, you are opening up your surface to accept the pigment. Then, while the board is still damp, apply color in washes with a soft natural bristle brush. Be sure to "float" the color over the surface instead of dragging the bristles across it – also a great technique for making transitional blends. Re-wetting may be needed as you work. Note that heavy water applications may release more air. Use a blow dryer to dry and to dissipate air if needed. Beginning with this method will result in a more even wash.

Glazing and Layering

Build layers of color by allowing each wash to dry thoroughly before applying the next layer. We call this hard drying. You may use a blow dryer or let the painting sit overnight. The base color will lift if it is still wet or damp when the second color is washed over it. By allowing paint layers to dry in between, you can apply an unlimited number of transparent glazes and achieve the most stunning reflective qualities impossible on any other surface. You may notice colors, especially darks, drying dull on the clay. However, they bounce back with super radiance when sealed and varnished.


Lifting and removing color is easy on Aquabord. You can create natural looking highlights and bring light back into your painting by using a damp nylon brush or a scrubber brush. You simply need a brush that doesn’t bend but pushes against the surface. Gently lift paint, rinse, and then blot the brush. You can do partial lifts or full lifts depending on the result you are seeking. Repeat these steps until you have reached a complete lift back to white or color you desire. Several tools can be used on Aquabord for lifting. A traditional round or flat nylon watercolor brush can be used. The nylon brush offers more resistance against the surface than a mixed bristle brush or a natural bristle brush. When more lift is required, a hog bristle acrylic brush may be used. To partially lift a glaze, gently lift paint once or twice until you reach the layer you wish to bring out. Using cotton swabs, a soft white eraser or sponges for lifting can also be very effective. As colors stack and the painting develops, return to areas and lift pigment. This allows altering of glazes, changing of values, and the creation of the desired textures and patterns. Allowing the board to dry between each removal of color will offer a clear, more controlled lifting. You can even add fine lines and details with a Scratch Knife or other Scratchbord Tools which will bring back the white of the board. You can also use tools such as sgraffito knives to cut into the surface and create sharp highlights.

Sealing and Framing

When the painting is complete and totally dry, seal Aquabord with a finishing spray and free your painting from the additional weight and glare caused when framing behind glass. Seal watercolors or gouache with several light coats of spray varnish. This is your "stop" varnish. Be careful to spray outdoors during warmer months or in a well ventilated and heated area during colder times of the year. Even though the pigments used may carry the highest permanency ratings, all artwork should be protected against the damaging effect of light and the pollutants in the atmosphere. We recommend the Krylon UV Archival varnishes. These spray varnishes offer advanced non-yellowing protection against fading, dirt, moisture, and discoloration. The Krylon UV Archival varnishes contain superior levels of UV light absorbers and are removable for conservation purposes. These varnishes are reversible with ammonia. For additional protection against scratches during transport and damage from ultraviolet light, follow the application of Krylon® spray varnish with Golden® Polymer Varnish with UVLS. Make sure that you use the polymer varnish, and not the one labeled, "MSA" in a metal can. This varnish comes in a matte, satin, or gloss finish and can be used according to individual preference. Always follow the manufacturer’s instructions for use, with any varnish and fixative. About four coats brushed-on, provides a very durable archival finish and is also removable. The complete artwork is framed much like a canvas might be without glass.
