How to Make Clay Plaster

Clay plaster is a great option for straw bale walls because it allows moisture to escape while providing the wall with a strong, breathable surface. It is also easy to apply, requires minimal maintenance, and offers a plethora of colors and finishes.

To make clay plaster, you mix a variety of materials together including a base coat of plaster, pigments, and a binder. The amount of each component may vary depending on the look and texture desired for the plaster.

A basic mixture for earthen plaster consists of clay, sand and a fibrous additive such as chopped straw. You can also add other ingredients to create a custom finish.

You will need a bucket for mixing your materials, a spatula or other tool to help move the mixture around in the bucket, and some safety equipment such as a dust mask. It is essential to wear eye and mouth protection while mixing plasters as it can produce large amounts of dust.

Before mixing the plaster, it is important to dampen any wall substrates. This will help the plaster to stick to the wall.

When mixing, it is important to mix the plaster thoroughly and evenly so that it does not bubble and crack. The consistency should be something between soupy and creamy mousse. If the plaster is too thick, it will take more work to trowel it on and could be difficult to apply.

It is recommended that you use a cement mixer or a bucket if possible to ensure that you are able to mix your plaster thoroughly and evenly. It is also important to flip the plaster often and mix with your feet to ensure that you have a smooth and consistent consistency.

Once the mixture is mixed thoroughly, you can then apply it to the wall. You should allow the plaster to dry before applying a second coat. It can take between two and three hours for the plaster to reach a leather-hard consistency. You can burnish the wall as it dries to achieve a fine, smooth surface.

This recipe will give you about 1/16 of an inch of plaster, but it can be a little thicker or thinner depending on the type and amount of fiber that you add to the mixture. You can also tint the plaster with pigments for a plethora of color options.

You can add up to 10% of fresh horse manure to this mix if you are making a cob plaster. This will increase the adhesiveness of the plaster, giving it a smoother and more glutinous texture.

The final step is to pour the resulting plaster onto your wall and spread it out with a trowel. It is important to spread it out evenly so that it reaches the entire surface of your wall. You can also burnish it after it dries to achieve a fine, even surface.

If you’re looking for a breathable, sustainable wall surface in your home or commercial space, clay plasters and renders are the best option. They are environmentally friendly, odourless, and very healthy for the occupants of your property.
