Paint With Sludge Paint | Tips And Advice

Sludge paint has been used in Sweden since ancient times. It is a natural and well-proven color that is best suited to facades with unplaned timber as timber. Sludge paint is inexpensive, environmentally friendly and relatively durable; You can expect that a newly painted fa├žade lasts for at least eight to ten years, longer if the house is in favorable conditions where it is not exposed to too much wind and rain.

Sludge paint is ideal for outdoor painting. The best time to paint is in the spring and early summer, when the temperature is comfortable and favorable to the color. Painting in direct sunlight on a hot summer day is not recommended because the paint then dries too quickly. If you are going to paint a sunny day, make sure that you start with the shadow side of the house and “follow the shadow” during the day.

What does slurry paint contain?

Sludge paint is nowadays usually made of pigments, rye flour or wheat flour and water. The pigment is, for example, the classic Falu Red color iron oxide, but sludge paint is also available in other colors of black, gray, green, yellow and brown. Boiled linseed oil is also an ingredient that often occurs, as it helps the color penetrate into the wood and also provides extra protection. You should always choose slurry paint that contains linseed oil when choosing color for the facade.

New paint with sludge paint

New paint with sludge paint should preferably take place after the facade has been left unpainted for one year, in order for the resin to dry out and the twigs to stop bleeding. Sludge paint is a relatively easy-to-use paint that does not require so much preparation, so be sure to do it with care! You should brush the facade with a brush or piassavast, so that all dust and dirt disappears. Also rinse the facade with cold water and allow to dry.

The first layer of paint should be mixed with about 15-20% water, in order for the paint to become slightly more smooth. It is important that the first layer of paint becomes really thin. If the color layers become too thick, the color will begin to flake. The second layer need not be diluted and should be painted when the old layer has dried for at least one day. For painting, it is best to use a brush with rough brush, such as a ceiling brush, horn suction or rough facade brush.

Paint a facade with mud paint

If you have a facade painted with sludge paint, it is the sludge paint you should paint with and nothing else. If, however, the facade is painted with, for example, an alkyd paint, you should not use sludge paint. Otherwise, about the same applies as for new painting; be sure to brush away flakes and excess color, then you can paint directly on the old color. Usually only one layer is required for repainting.

Replace shade when repainting with slurry paint

If you want to change the hue of the house a little more preliminary work is required, otherwise it will be easy for the old shade to light up after a few years. You should clean the facade thoroughly and then wash with a paint cleaner and then scrub loose loose paint with a rough brush. Then clean the facade thoroughly with lukewarm water and allow to dry.

Then you, as we do new paint, first make a layer of diluted paint, dry one day, then undiluted paint in a thin layer.
