Chalk Wash
Chalk wash is a permeable matt decorative paint based on natural, sustainable ingredients including animal size and fine chalk. It is slightly transparent and intended to replicate the look of limewash on substrates limewash might not be suitable for. It is a semi transparent paint and ideal for use to create layered decorative effects such as ragging, French wash and dry brushing. Artist quality earth and natural powder pigments provide matchless purity and quality of colour. Much of the charm of chalk wash is the lack of uniformity with subtle variations of colour and tone.
Chalk wash is available in all of our standard colours but, due to its semi-transparent nature, colours in chalk wash may appear lighter.

Preparation
Ensure Chalk Wash is within shelf-life period. All surfaces should be sound, dry, and free from dirt, oil, grease or other contamination. New lime plaster should be allowed to carbonate and dry for at least four weeks prior to application. Any fungus or mould must be treated with a fungicide and making good and filling should be carried out with a material appropriate to the substrate. It is recommended that trials be carried out to ensure that the surface is suitable for application.
Application
As this paint is used for colour/ tonal effects the number of coats will depend on the effect you are trying to achieve. Apply by brush and then use various tools/brushes/muslin cloth/crumpled paper etc to achieve the desired effect. Dampening a porous surface with clean water and a sprayer may be beneficial as this will extend the drying time allowing the desired effect to be created. Chalk Wash can be applied directly to the wall surface or can be applied over a solid colour background as a starting point, Rose of Jericho distemper can be used as a ground on most surfaces that need to be permeable. On gypsum plaster or previous emulsion painted surfaces Rose of Jericho Permeable Matt Emulsion or casein distemper can be used if a base coat is required. Chalk Wash is a thick gel that brushes out readily, and thinning should not be necessary. Chalk Wash is temperature sensitive and will thicken in cold conditions. It can be returned to the correct consistency by placing in a warm room or standing the can in a bucket of hot water. Stirring with a mechanical whisk can be advantageous for application to certain surfaces. Only if necessary dilute by no more than 10% water and whisk thoroughly. Brushes and equipment should be cleaned with warm, soapy water immediately after use.
