Eco friendly interior paint

Part 3

The following list looks at natural and eco friendly interior paint ideas for your walls and ceilings

Eco friendly interior paint - First choice
Linseed oil based paint
Linseed comes from the flax plant is an ideal resource that is renewable, sustainable and readily available. Some sources are found in by-products from the food industry. The content of linseed oil in paints can vary with some types that are made with 100%.

Eco friendly interior paint - Second choice
Wood and vegetable oil based paint
Made from natural elements such as soya bean oils, oak bark and madder root – readily available and renewable materials. Vegetable based pigments fade over time. Natural VOCs are released from natural resins like turpentine and citrus oils – these VOCs are not as toxic as traditional synthetic paint. Low levels of embodied energy.

Casein, protein, distemper, milk based paint
An old fashioned interior paint mix made from milk protein and lime. Materials are non chemical, renewable and readily available. The product comes in powder form, to be mixed when needed. The casein/milk acts as the binder. Raw materials are a non renewable resource extracted through quarrying, which destroys the surrounding natural environment. Application may cause skin and eyes sensitivity as lime is a known irritant. Some sources are found in by-products from the food industry. Suitable for interior and exterior applications. A breathable, water based and non toxic paint. Multiple coats are needed for an opaque finish. Milk paint is not appropriate for damp environments as this causes the paint to flake. The finish is washable, matt, soft and chalk like.

Clay based paint
Natural clay is a readily available and non toxic resource. Available in a small variety of colours. Finish is entirely breathable and has very good natural anti fungal and anti static properties. Entirely breathable finish which helps humidity and trapped moisture levels. Available in flat matt or textured wall effects. Good anti-static properties. A naturally non drip paint without polyurethane. Low levels of embodied energy.

Stone and mineral paint
A water based paint made from crushed stones and minerals such as limestone, soap stone, quartz sand and dolomite without the use of solvents. Materials are readily available. Mineral pigments are available in bold colours and do not fade as easily as vegetable based paints. Durability on porous surfaces is very high. Good light reflectivity. Interior paint finish is entirely breathable and has very good natural anti-fungal properties. These finishes create the same surface properties found in natural stone. Non combustible. Medium levels of embodied energy.

Lime, lime wash, whitewash, distemper paint
An alkaline powdered chalk or lime based paint which is suited to painting on top of a clay or lime plaster base. Raw materials are a non renewable resource extracted through quarrying, which destroys the surrounding natural environment. Quite a soft finish which can flake. Good anti-fungal properties. A breathable, water based and non toxic paint. Contains very low level of VOCs. Multiple coats are needed for an opaque finish. Application may cause skin and eyes sensitivity as materials are known irritants. Some paints contain acrylic polymers. Cannot be painted on gypsum plaster walls.

Eco friendly interior paint - Third choice
Low-odour, low VOCs or zero VOCs paints
There is some conflicting information surrounding these paints as low odour paints ‘seem’ to be safe as they do not give off the typical paint smell – leading you into a false sense of security. This does not mean that they are safe, only that a different chemical process has been used.

Eco friendly interior paint which state zero VOCs may well be made with alternative chemical and toxic substances which are not classed as VOCs. Paint which states low VOCs offgas lower levels of chemical vapours than synthetic paints. Both zero and low VOCs paints could have as a negative effect on your health, wellbeing and to the natural environment as traditional synthetic paints do, even though the level of exposure might be reduced. It is important to note that low VOCs still offgas, however the level is lower than with traditional paint types. There are currently no legislations as to what a low or zero VOC paint can contain to be put into this class.
