What Happens if You Varnish an Oil Painting Too Early – The Quick Answer:
Varnishing is a crucial step in preserving an oil painting’s longevity and bringing out its colors. The best time to apply varnish is after the painting has fully dried, which usually takes around six months. Choosing the right type of varnish depends on factors like the type of paint used and intended display environment. Natural resin varnishes may yellow over time, while synthetic ones remain crystal clear.
Understanding Varnishing in Oil Painting
What is Varnish?
Varnish is a clear, protective coating applied to a completed painting. The purpose of varnish is to protect the paint surface from dirt, dust, and other environmental factors that can damage it over time.
Why Do Paintings Need Varnishing?
Oil paintings are prone to collecting dirt and dust, which can stick to the surface and cause discoloration or even damage over time. Varnishing helps prevent this by creating a barrier between the paint surface and the elements. Additionally, varnishing brings out the colors in an oil painting and gives it a uniform finish.
The Different Types of Varnish
There are two main types of varnish used for oil paintings: natural resin and synthetic. Natural resin varnishes are made from plant-based resins like damar or mastic, while synthetic varnishes are made from acrylic resins. Natural resin varnishes tend to be more traditional and have been used for centuries, while synthetic varnishes offer greater flexibility and durability.
The Importance of Choosing the Right Type of Varnish
Choosing the right type of varnish depends on several factors including the type of paint used in the artwork and its intended display environment. For example, natural resin varnishes may yellow over time due to their organic nature, while synthetic ones remain crystal clear.
The Best Time to Varnish an Oil Painting
How Long Should You Wait Before Varnishing?
The best time to apply varnish is after the painting has fully dried – this usually takes around six months for an average-sized artwork. However, some artists prefer to wait longer before applying a coat of varnish.
Why Wait So Long?
Allowing the paint to dry fully before varnishing is essential to ensure the painting’s longevity. If varnish is applied too early, it can slow down the drying process and prevent the oil from hardening completely. This can lead to cracking, yellowing, and other issues.
How Can You Tell When a Painting is Ready for Varnishing?
To determine if a painting is ready for varnishing, gently touch the surface of the painting with your fingertips. If there is no tackiness or stickiness, it’s safe to proceed with varnishing. Additionally, you can use a magnifying glass to inspect the surface for any signs of cracking or discoloration that may occur if you apply varnish too soon.
Risks of Varnishing an Oil Painting Too Early
What Happens When You Varnish Too Early?
Varnishing too early can have detrimental effects on an oil painting’s longevity. The main concern is that it can cause cracking and discoloration in the paint surface due to incomplete drying of the underlying paint layers.
The Risks of Cracking
When varnish is applied before the paint has fully dried, it traps moisture underneath, which causes expansion and contraction in the paint layers. This leads to cracking over time, which can ruin the artwork’s overall appearance.
The Risks of Discoloration
Another risk associated with applying varnish too early is that it may cause discoloration in certain types of pigments used in oil paints. For example, ultramarine blue pigment tends to fade when exposed to sunlight over time. Applying a layer of varnish too soon can accelerate this process and cause irreversible damage.
The Impact of Varnishing on the Drying Process of Oil Paint
How Does Varnishing Affect the Drying Process of Oil Paint?
When varnish is applied to a painting, it creates a barrier between the paint surface and the environment. This can slow down the drying process by trapping moisture underneath and preventing air from reaching the paint surface.
The Importance of Allowing Paint to Dry Completely
Allowing oil paint to dry completely is essential for ensuring its longevity. When oil paint dries, it hardens and becomes more stable, which prevents issues like cracking and discoloration over time. Varnishing too early can interfere with this process and lead to irreversible damage.
The Importance of Proper Ventilation
To ensure that oil paintings dry properly, it’s important to provide proper ventilation in the studio or workspace. This means allowing fresh air to circulate around the artwork and keeping humidity levels at an optimal level. Additionally, using fans or dehumidifiers can help speed up the drying process without compromising quality.
Possible Effects of Varnishing on Cracking and Yellowing in an Oil Painting
Can Varnishing Cause Cracking in an Oil Painting?
Yes, applying varnish too early or using an unsuitable type of varnish can cause cracking in an oil painting. When varnish is applied before the paint has fully dried, it traps moisture underneath, causing expansion and contraction within the layers of paint. Over time, this leads to cracking.
Can Varnishing Cause Yellowing in an Oil Painting?
Yes, certain types of natural resin varnishes may yellow over time due to their organic nature. This is especially true if they are exposed to sunlight or high levels of heat or humidity. Synthetic varnishes generally do not yellow over time and tend to be more durable.
The Importance of Choosing the Right Varnish
Choosing the right type of varnish is crucial to ensure that it does not cause cracking or yellowing over time. Synthetic varnishes tend to be more durable and do not yellow, making them a popular choice for many artists. However, natural resin varnishes can provide a traditional look and feel that some artists prefer.

Signs That Indicate an Oil Painting is Ready for Varnishing
Why is Varnishing Important?
Varnishing is an essential part of oil painting. It not only protects the painting from dust, dirt, and other environmental factors but also enhances its colors and gives it a glossy finish. However, varnishing should be done at the right time; otherwise, it can lead to problems like yellowing or cracking.
How Long Should You Wait Before Varnishing?
The general rule of thumb is to wait for six months before varnishing an oil painting. This time allows the painting to dry completely and settle down. However, some painters prefer to wait longer than six months to ensure that the paint has fully cured.
Signs That Indicate Your Painting is Ready for Varnishing
Here are some signs that indicate your oil painting is ready for varnishing:
The Painting Has Dried Completely
The first sign that your painting is ready for varnishing is when it has dried completely. To check this, touch the surface of the painting lightly with your finger. If it feels dry and hard, without any tackiness or stickiness, then it’s ready for varnishing.
The Colors Have Settled Down
Another sign that indicates that your painting is ready for varnishing is when the colors have settled down. When oil paints dry, they tend to darken and lose their sheen. However, after a few weeks or months, they regain their original brightness and luster. Once you notice that the colors have settled down and look stable, you can proceed with varnishing.
The Surface Is Even
The third sign that indicates that your painting is ready for varnishing is when the surface is even. Sometimes, oil paints can dry unevenly, leaving lumps or bumps on the surface. However, after a few weeks or months, they tend to smooth out and become even. Once you notice that the surface of your painting is smooth and even, you can proceed with varnishing.

Frequently Asked Questions about What Happens if You Varnish an Oil Painting Too Early
How soon can you varnish an oil painting?
To properly varnish an oil painting, wait at least six weeks for a thinly painted piece or one year for a heavily layered piece. However, if you are unable to wait that long, you can apply the varnish within a few weeks of completing the painting, as long as it has dried completely.
How long should you wait to varnish a painting?
Before applying varnish, make sure that the painted surface is completely dry, which can take anywhere from 72 hours to two weeks based on its thickness. Additionally, make sure that your workspace is well ventilated and free of dust.
What happens if you varnish an acrylic painting too early?
To avoid a cloudy finish caused by trapped moisture, it is important to wait until the acrylic paint has fully dried before applying varnish to your painting. I recommend waiting at least a week, but some artists wait up to six weeks to ensure complete drying.
Can I finish an oil painting the next day?
The duration for oil paint to dry is not fixed. It can take from one day to a few weeks, months, or even years to fully dry.
What happens when you varnish too early?
Oil paint dries through an oxidation process, which means that if varnish is applied too soon, the paint will not have access to the oxygen that is necessary for it to dry properly.
Do you have to wait 6 months to varnish an oil painting?
Varnishes have permeable properties, meaning that oxygen can pass through them, allowing oil paint underneath to cure. However, the application of varnish also slows down the drying process by limiting the amount of oxygen that enters the paint film. Many painters prefer to wait for a minimum of six months before applying varnish to ensure proper curing.
