    PAINTING WITH EGG OIL TEMPERA


    Many choose egg oil tempera for environmental and health reasons, thanks to its pure and natural content - free from additives and solvents. Others choose egg oil tempera simply because it produces an incomparably beautiful result. Do you also want to paint walls or furniture with egg oil tempera? We offer a variety of shades of egg oil tempera here. In our stores, you can also get assistance with ordering tempera paint and purchase a sample jar to take home with you.

    Sub-labour

    Because the egg oil tempera colour is so thin and fine in its structure, it is worth taking extra care with the undercoating to get a really good end result.

    A fine-grained filler should be used for levelling. Filled surfaces require a first coat on top of the filled surfaces as there is a risk of "suction" on these surfaces. Then 2-3 more coats on the entire surface.

    New wood

    Priming is not necessary. If the surface is very absorbent, the colour can be diluted with water or emulsion during the first coat. Knots should be shellaced before painting to avoid penetration.

    Previously painted surfaces

    Loose paint is scraped off, filled and sanded if necessary. Shiny surfaces are matted with a fine sandpaper, then the surface is washed clean.

    Plastered surfaces

    Loose plaster is brushed off and the surface repaired. The surface is then best saturated with water and then painted with egg oil tempera on a wet surface.
    Note! Freshly plastered walls must be fully 'burnt' before they can be painted.

    Colour consistency

    It is important that the colour has the right consistency when painting. Thinning can be done with water or emulsion. The colour should always be easy to brush or roll. Paint that is too thick "sets" quickly and is difficult to paint with unsatisfactory results, and the paint also becomes very unattractive. The different pigments in the paint behave very differently in the paint mixture. Some pigments fill well and give a thicker colour, others give a thin colour regardless of how much you mix in. In general, you can say that light-coloured pigments give a thicker consistency and coloured pigments a thinner consistency.

    Painting with a brush or roller

    Brush

    The colour type is not very picky about the choice of brush, but a semi-soft/soft paint or ceiling brush made of hog bristle or mixed bristle is perfect. Stir the colour well so that the pigments are properly distributed. Normally, 2-3 coats are required to achieve an opaque painting. Subsequent coats can be done after about 12 hours.

    The brush should move easily in the paint. If the resistance increases, it is because the water in the paint has been absorbed into the surface. The colour "sets" quickly (1-2 minutes). As long as the surface is shiny, you can continue to work with it, but when it has become matt, so much water has evaporated that there is a risk of removing previously applied paint instead. When painting larger areas, it is important to work quickly to get as even a surface as possible.

    Roller

    If you want to paint with a roller, pour the paint onto a disc and fill the roller from the disc. It is easy to get too much paint in the roller if you use a roller trough or a can. Roll as usual but apply the colour thinly. Normally, 2-3 coats are required to achieve an opaque painting. Subsequent coats can be done after about 12 hours.

    Drying time

    The egg oil tempera requires light and oxygen to become dry and cured. It is an advantage if the place is well ventilated. The tempera dries in two stages, first the water evaporates, then the linseed oil oxidises. The paint is dust-dry after about 1 hour, paintable (with tempera paint) after about 12 hours, surface-dry after 2-7 days, i.e. it does not stain when touched.
    Note! Surface dryness is very different for different colours. The colour is fully cured after 3-4 weeks. When the paint is fully cured, it is very durable.


    Finishing of painted surfaces

    Egg oil tempera provides a beautiful matt and diffused surface that can be treated in different ways to increase the gloss and make the surface more durable.

    Shine brushing

    If an "eggshell gloss" is desired, e.g. on furniture, the surface can be brushed with a panel brush, bath brush or magic wool. Brushing can be done after about 2-3 weeks of drying time. Try first on an inconspicuous surface, so that the colour is sufficiently hardened.

    Waxing

    Waxing the surface can be done with e.g. beeswax or linseed oil wax. The wax increases the gloss and to some extent "closes" the colour, which becomes more resistant to soiling.


    Cleaning of painted surfaces

    Thoroughly hardened surfaces are cleaned with a mild, neutral detergent such as dishwashing liquid, soap or olive soap available in all Norrgavel stores. Soak the stain and the surrounding area with a sponge. Try bathing the stain. If this is not enough, let the cleaner work for a while. Then take a soft or medium-hard brush and brush the stain with short strokes. Also brush the area outside the stain so that any change in lustre is less obvious.

    Consumption and storage of colour

    One litre of paint is enough for about 10 square metres per coat - depending on the surface and the consistency of the paint. Unopened paint can be stored at room temperature for about two months. Store the paint in a cool but frost-free place to extend its shelf life.
