Different types of paint require different waiting times before applying a second coat because their drying times vary based on their chemistry. We’ve prepared a detailed guide on how long to wait between paint coats for popular options like water-based, oil-based, and cellulose paints. Before applying the second coat, it’s also important to consider room temperature.
How Long to Wait Between Paint Coats
Room temperature is one of the most critical factors in determining when to apply the second coat of paint. For example, a second coat of water-based paint is typically applied after 3–4 hours. However, if the temperature drops below freezing, this waiting time will naturally increase.
Although the second coat is usually the final layer, a third coat may be needed to cover a very dark color, or a suitable primer may be applied beforehand.
Another important reason to extend the waiting time before applying the second coat is that it improves the paint’s coverage. The longer you wait before applying the second coat, the better the coverage will be. “Related article: Can you paint over dark colors without primer?”
Water-based wall paints can be latex, silicone-based, Teflon-infused, or acrylic. For all these types, the recommended waiting time between coats should be at least 5–6 hours, as advised by the paint manufacturers. However, these recommendations are based on average room temperature conditions.
If the room temperature is between 77–95°F (25–35°C), you can apply the next coat after 3–4 hours. The paint’s silicone content, quality level, or dilution with water does not affect the waiting time between coats.
During summer, we recommend waiting 3–4 hours between coats for water-based wall paint. In winter, the waiting time can extend up to a full day. “Related article: Painting in cold weather.”
When to Apply the Second Coat of Oil-Based Wall Paint?
Synthetic wall paints are among the slowest-drying types of paint. Applying the second coat too early can cause issues on the wall.
If the second coat is applied too soon, it may lead to drying problems or lingering odors. In fact, applying the second coat too early can significantly delay the drying process, and the paint’s smell may persist for weeks. “Related article: Oil vs. Water-Based Stain.”
Before applying the second coat of synthetic paint, you should wait at least 24 hours and ensure proper ventilation. Using heaters to speed up drying and applying the second coat sooner than recommended can cause bubbling and blistering in the paint.
In summary, for oil-based paint, wait at least 24 hours before applying the second coat in summer. In winter, it’s best to wait up to two days for optimal results.
How Long to Wait Between Ceiling Paint Coats?
In some areas, a separate type of paint is used for ceilings. Ceiling paints are similar to wall paints and are typically water-based. They are also among the fastest-drying paints.
Just like with wall paint, the waiting time between coats is important for ceiling paint. In summer, wait 3–4 hours between coats, while in winter, the waiting time can extend up to a full day.
When to Apply the Second Coat of Cellulosic Paint?
Cellulosic paint is one of the fastest-drying types of paint, but it is mainly used for painting metal and wood surfaces. It dries so quickly that when applied with a brush or roller, the brush may stick to the surface. For this reason, cellulosic paint is typically applied using a spray gun.
In general, 30 minutes is enough before applying the second coat of cellulosic paint. However, this time may vary. For the best results, always follow the application instructions on the paint’s packaging.
Frequently Asked Questions
The most frequently asked questions about paint drying time between coats are answered below. Feel free to ask any other questions in the comments section.
When to apply second coat of paint?
Water-based wall paint, latex wall paint, and acrylic paint require at least 3 hours before applying the second coat. However, if the room temperature is low, this waiting time can be significantly longer.
Does paint get darker or lighter when it dries?
High-quality paints usually darken after drying, while low-quality paints may lighten in color.
When painting how long between coats?
You should wait at least 3–4 hours between coats of wall paint. However, if the weather is cold or the paint is oil-based, this waiting time can extend up to 24 hours.
When can i paint after primer?
If your primer is water-based, you can start painting after 3–4 hours. However, if your primer is oil-based, you should wait at least 24 hours. “Related araticle: do i need to prime before painting.”
What happens if you apply second coat of paint too soon?
The paint will take longer to dry, it may smell for an extended period, and its coverage will be reduced.
What should you do before applying a second coat of paint?
Before applying the second coat of paint, make sure the first coat is fully dry. You can check this by touching the paint and looking for any color change. However, still wait at least 3–4 hours for the paint to dry, as the inner layers may not be fully dry yet.
How do you know if paint is dry enough for a second coat?
To know if the paint is dry enough for a second coat, you can perform a simple touch test. Gently touch an inconspicuous area of the painted surface. If it feels dry and does not leave a mark or smudge, it’s likely ready for the second coat. Additionally, the paint may change color slightly as it dries, indicating it’s no longer wet. However, even if the surface feels dry to the touch, it’s best to wait at least 3–4 hours (or longer, depending on the type of paint and room temperature) to ensure the paint has fully cured, especially underneath the surface.
Can you do two coats of paint same day?
Can you do two coats of paint the same day? If your paint is water-based, you can apply two or even three coats on the same day. However, if your paint is oil-based or synthetic, we recommend applying the second coat the next day.
