The difference between closed paint and open paint

Nowadays, every house needs to be renovated. During the renovation, it is inevitable to encounter the problem of painting. Whether the selected paint is healthy or not, the key still depends on personal experience in paint. This includes furniture and walls. If the selected paint is not good, it will also cause some health risks to the human body. Let us take a look at the difference between closed paint and open paint.

Sealing paint

Sealed paint is generally used to spray the surface of the product. The natural texture of the wood is covered and sealed by the paint, so the surface is smooth and has a mirror effect.

Closed paint and open paint are two painting processes for wooden doors or furniture when processing the veneer surface.

Open paint structure Open paint (mainly nitrocellulose lacquer) is a coating process that completely reveals the pores on the wood surface. Its main component is polyurethane (PU) with a low concentration. It features obvious wood pores, clear texture, small amount of paint applied, matte finish, strong natural texture, and can be repaired twice. However, it is expensive and requires high spraying technology, requiring six, seven or even more than ten passes.

These two painting techniques are suitable for furniture made of different woods. If the wood's ducts are thin and dense, such as birch or maple, it is recommended to apply sealing paint. Open paint can only be used if the ducts are deep and obvious, such as high-grade woods such as oak and ash.

Wood wax oil is a natural wood coating that is similar to paint but different from paint. It is completely different from the current paint produced based on petrochemical synthetic resins. The raw materials are mainly refined linseed oil, palm wax and other natural plant oils and plant waxes combined with some other natural ingredients. Even the pigments used for coloring are food grade. Therefore, wood wax oil does not contain toxic ingredients such as triphenyl, formaldehyde and heavy metals, and has no pungent smell.

The working principle of wood wax oil: the oil in wood wax oil can penetrate into the interior of the wood, giving the wood deep moisturizing and maintenance; the wax can combine closely with the wood fibers, enhance the surface hardness, and make it waterproof and stain-proof, wear-resistant and rub-resistant. This golden combination provides the most outstanding maintenance and decorative effects for the wood.

The effect of using wood wax oil: Wood wax oil can completely penetrate into the wood, so it is completely different in appearance from traditional paint with paint film. The surface has an open texture effect. Different woods can bring different real touches, and it can be partially repaired and renovated without leaving any traces. The construction is also very simple. Only one or two coats are required. It is very suitable for DIY and will not cause harm to the health of construction workers.
