Product Information
Data Sheet

Earthborn Wall Glaze is a water based, clear glaze for interior use. Being virtully VOC and acrylic free, it is specially formulated for its environmental benefits. This resourceful product can be used for a whole host of projects. Use before painting to stabilise sandy, powdery interior surface.

Apply on top of Earthborn Claypaint to produce a washable, protective glaze*. Or combine it with Earthborn Pigment to create special paint effects such as sponging and colour washes, as well as an interior wood stain. You decide.


Top tip:

When using as a glaze, it is best applied with a spray bottle, working from the bottom upwards. This will help prevent drips.

For decorative effects, use a sponge.


Approx coverage 50 square metres per litre.
Approximate coverage when diluted and used as a glaze.


*If used over a painted finish as a glaze, the low sheen level of Wall Glaze may change the appearance of the paint. We recommend testing first to ensure that you are happy overall look.

Colours on screen may vary from actual paint. Slight variations in colour can occur between batches and finishes; the substrate and texture of the surface can also change the appearance of the final colour, as can lighting.

Advice is given in good faith but without warranty as methods of application and site conditions are outside of our control.

  • What is Earthborn Wall Glaze used for?

    Earthborn Wall Glaze is a highly versatile, water-based medium with a range of uses:

    1. When diluted with water it will bind powdery or dusty surfaces prior to painting. Because it’s highly breathable, it’s especially suited to stabilising old or powdery lime plasters. We’d always recommend removing as much loose and flaky material as possible before applying, but using a diluted coat of Wall Glaze will help to prepare the surface ready for painting.
    2. Applied on top of Claypaint, Wall Glaze provides a hardwearing, durable finish whilst remaining breathable. So if you have used Claypaint on lime plaster, you can be assured that Wall Glaze will remain breathable (when diluted in the correct ratio) and give the painted surface some extra protection!
    3. Wall Glaze is ideal for protecting bear interior brick or stone walls.
    4. Wall Glaze is the perfect medium for mixing with our range of powder Pigments. If you’re feeling creative, you can create a myriad of effects including broken colour work, colour washes and marbling. Simply mix your chosen Pigment shade into a little water to create a paste, then mix into the Wall Glaze until you achieve the desired depth of colour. It can be applied with a brush, sponge, rag or other technique.
  • I have prepared the wall to be painted but the surface is powdery. Should I treat it with PVA?

    No. PVA will partially seal the surface, which can be detrimental to the building structure and result in a less comfortable living environment. Therefore, other than in special cases, PVA should be avoided. First try brushing the surface thoroughly with a stiff brush. If the surface remains powdery, stabilise it with a solution of Earthborn Wall Glaze and water.

  • Which Earthborn paint is most suitable for kitchens, bathrooms and high traffic areas?

    For high traffic areas like family kitchens, bathrooms or hallways, Earthborn Lifestyle emulsion offers a durable, washable surface with a classic low-sheen finish.

    For high traffic areas with lime plaster, a breathable paint finish should be used. We’d recommend using Earthborn Claypaint, which can be finished with a diluted coat of Wall Glaze to protect the surface and maintain its breathability. Please note that Wall Glaze can slightly alter the appearance of Claypaint so we would recommend testing an area first – sample pots are available to buy here in both Claypaint and Wall Glaze.
