Making Claypaint, Home-made Ecological Paint for Interior Walls Part 2

When the wheat paste was cool we were ready to go ahead with the next part of the process. We decided to add a little of our earth pigments, a red and yellow ochre, to avoid the grey tone that you can get with clay and flour paints. We intended testing the paint out on the window recess to give us a good idea of the resultant finish and hue when dry. We argued that even if the colours were slightly different in tone to the rest, the effect could be quite pleasing. For example, in the sitting room we purposely covered the window recesses in a sand and lime mixture to create a contrast to the linen and lime. In the event the paint went on so well and tiny patches of it dried within the first few minutes, giving us such a good idea of the finish, so we pressed on and completed the whole wall.

A Foreword on the Clay Paint Ingredients


Kaolin


Kaolin was named after the high hill or 'Kao-ling' in Jiangxi Province from which the first major deposits of fine white clay were mined. Porcelain had become an important commodity in the T'ang Dynasty, (618-907) with the popularity of tea drinking but it was under the Song dynasty in the early 11th century that the town of Jingdezhen with its invaluable high hill became the centre of the Imperial porcelain manufacture. Thus Kaolin, also known as China clay, was the foundation of the fabulous Chinese porcelain industry, which for so many centuries held sway over the World's passion for fine tableware and objets d'art. These were not only made of the finest white clay but also cobalt, the latter allowing artists to experiment with a new colour. A later addition of manganese in the Ming dynasty would lead to the apogee of China's famous 'blue and white'.  Jingdezhen was ideally situated near to the Poyang Lake whereby tons of dinner services could travel by lake and river to Nanking and then onwards via the Grand Canal to Peking and from there out to the Courts and stately homes of the West. Below is an example of 19th Century Staffordshire 'Willow Pattern', a ubiquitous English transfer design which was heavily influenced by the earlier century's Chinese imports.

Kaolin is also used as a beauty product being a component of many cosmetics particularly nowadays for organic make-up and toothpastes and on its own as a beauty mask.

The fine white clay has therapeutic qualities as do many of those coming under the banner of healing clays, such as Montmorillonite aka French Green Clay. It can be used externally to draw impurities from the skin and toxins from the body. The best quality sun-dried therapeutic clays are also used internally, as clay water drinks to remove, poisons, including heavy metals and radiation. Kaolin is often viewed as a more gentle detoxing clay than the bentonite clays for example. We have used therapeutic clay many times on our poultry and ourselves! See related articles below.

Ingredients 

The basic measurements for the paint are as follows:

4 parts water to
3 parts Kaolin to
1 part wheat paste
Pigment as required

For the kitchen's North wall which is approximately 7m² or just over 75 square feet we made up the paint in the following proportions:

1 litre or 4 cups of water
400g or 3 cups of white clay powder aka kaolin
225 ml or 1 cup of wheat paste

This was a guesstimate as our wall has a textured surface so would take more paint than a smooth surface, in actual fact I was able to easily cover the wall and go over it again in the parts I'd missed or where the texture was more pronounced. Judging by the coverage, a smooth wall would have only needed one coat and thus used less paint. 

Method


How to make claypaint
Add the water to the clay and mix thoroughly, I used a wooden spoon to start the process as I thought it would be less messy. Also this is very fine clay so I didn't want to make 'dust'. Otherwise you may want to wear a mask at this stage if you have one that is suitable.

Add the wheat paste and mix again. We did try to use a drill attachment whisk at this point but the one we have is really for very large volumes, so it was rather messy!



using earth pigments for  making claypaint



Add the pigment to a little water and mix the whole lot together again. This time we used a normal electric hand whisk, which worked really well.




If you don't use the paint for a few days it starts to smell 'funny' aka old-style metal polish mixed with stagnant water! However, that doesn't prevent you from using it, as it looks fine, dries well and with no odour. It's just better to use it as you make it!

As the paint was meant to leave just a fine layer over the original surface and so that it would retain its 'crunchy' aspect we made our paint quite thin. If you want a thicker paint then add less water and if you want texture then add fine sand. (We will be sharing the making of claypaint made with sand in a future article.)

Preparation & Application


Cleaning hemp and lime covered walls



We started by brushing and then washing down the walls to remove any grime which might impede the application and adhesion of the paint. Most of the discolouration is from cooking and soot from numerous chimney sweepings. As it has been over 15 years since we applied this layer of hemp and lime,  I think it has been a great success as an easy-care wall-covering! This apart, of course from being excellent insulation for a stone wall.

We worked the paint into the surface of the hemp and lime using a circular motion in the more textured parts of the wall.






Home-made claypaint drying times







After two hours and on a rather dull and cool day for July, the paint looked like this.







Making clay paint for interior walls
We're very pleased with the result! The North wall of the Kitchen, which was the first wall covering we applied back in 2002 was beginning to look its age. The clay paint has freshened it up but without giving it too much contrast to the rest of the Kitchen. It is the darkest side of the room and can stand the extra luminosity the clay provides. I was also pleased how bright this paint was as we had expected the kaolin to dry with a greyish tone but of course we had added a little pigment. However, this may also be due to the fact that the only kaolin which was readily available here was cosmetic grade! This paint was easy to make and apply and for me has none of the stark, rather clinical look of lime paint. We also love the fact that it is in keeping with the ethos and aesthetic of our organic hemp and lime wall covering.

Here's the film:



Now we've just got to make another batch up to finish off the wall between the sink and the chimney! Next up will be the sand and clay paint to cover the window recess in the bedrooms and then we'll be starting with an organic linseed-oil-based paint for the exterior woodwork. So there's plenty to come and I hope you'll join us. In the meantime all the best from a rather stormy Normandie and please feel free to share, comment or ask for further information on this topic,

Home-made Ecological Paint for Interior Walls Part 1 Making Wheat Paste

We want to freshen up our existing wall covering in the Kitchen, just in the areas behind the stove. We originally covered the wall in 2002, fifteen years ago and we cook every day on a wood cooker, so the wall areas around the stove have taken a bit of a beating! We did some research as to what we could cover it with and came up with a few alternatives.



Our options were to:

  • add another layer of hemp and lime over the top of the original using a finer 'finishing' grade of hemp.
  • find a suitable eco-paint that would cover the wall and yet still have the same finished aspect as the existing surface.
  • make our own eco-paint and therefore by experimentation, be sure the surfaces were as similar as possible. 



We considered the first option from both an economic and aesthetic point and found two problems. On the cost front, we had originally used a horticultural grade organic hemp, normally used as mulch and which we had bought in bulk from an agricultural/market-gardening suppliers at a very competitive price. The finishing organic hemp, however came under the auspices of interior decoration/design and was thus both pricey and more importantly very difficult to source! From an aesthetic point we had levelled off the hemp and lime to the surface of all the electrical installations and woodwork, so adding another layer would be troublesome and end up looking like an afterthought. It was also more likely too that we would end up having to redecorate the whole Kitchen if we chose this option.

The second option was conversely a very easy one, as we have an alternative builders merchant just a couple of minutes away from where we live. On the economic front, the paint is quite expensive and after all we are quite capable of making our own! Therefore we chose the third option.

Ecological paint, like a good organic food recipe is made up of just the basic necessary ingredients, it is simple and seemingly, very easy to make. It has substance aka filler, the ability to stick on the wall, i.e. glue, coverage aka water and a colour, natural pigment. As an option you can also add a texture, such as hemp, straw, sand, linen etc.,.

Wall Paint Recipe Step One - Making the Wheat Paste or Glue Element





This is something we have made before when we were creating papier mâché puppets and it is known as wheat or flour paste. It makes terrific glue by the way. It's only drawback being that it is tasty. Our friend's Golden Retriever (here left looking extremely guilty) chewed the ear off one of our puppets at an exhibition!




INGREDIENTS


1 litre or 1 US Quart of boiling water
225 ml or 1 cup of cold water
225 ml or 1 cup of sieved organic flour*
This will make approximately 1¼ litres or 5 cups of paste

*we are using spelt because we were given a whole sack full from our local organic shop as it had weevil activity! However, most people advocate plain white flour.



METHOD


Mix the cold water and flour together to form a smooth paste.

Slowly add the boiling water to the mix, stirring continuously until the liquids are well incorporated and without lumps. You can always sieve again at this point if you have a problem.

Return pan to heat and bring to boil, stirring continuously.

Keep stirring and count ten seconds after the boil and then remove from heat.

Cover and leave to cool.


Storing wheat paste


In hot weather the paste will keep for a couple of days before going off. It should be covered and kept in a cool place such as a pantry or refrigerator. A skin will form on the top of the paste and this should be removed and discarded (it can be composted) before use.

Next stage and film coming very soon, as we will be painting the walls tomorrow!


All the best and thanks for dropping by. Please feel free to share this article, comment and/or ask for further information.

Until next time!
