What You'll Learn
Keeping a wet edge prevents awkward lines
When painting, it is generally recommended to keep a "wet edge" between the cut-in and the rolled paint to prevent visible lines and achieve a smooth, professional finish.
The "cut-in" refers to the paint along the edges of the surface applied with a brush, while "rolling" involves applying paint to the main area of the surface with a roller. Keeping a wet edge means ensuring that the cut-in paint is still wet when you start rolling, allowing for a seamless blend between the two.
If the cut-in paint dries before rolling, it can result in picture framing, where visible lines or frames appear between the cut-in and rolled areas. This occurs because the dried cut-in paint creates a distinct edge that the roller cannot fully blend with, resulting in an uneven finish. Additionally, texture differences between the smoother brush finish and the slightly bumpy roller finish become more noticeable when the cut-in paint dries, leading to a wall with visible variations in texture.
The shine level of the paint also affects the final result. Satin, semi-gloss, or glossy finishes tend to reflect more light, accentuating inconsistencies in texture or application. Therefore, it is crucial to work in smaller sections and maintain a wet edge when using these higher-sheen paints. On the other hand, flat and eggshell finishes are more forgiving, and visible lines may not be as prominent if the cut-in dries before rolling.
However, there are exceptions to the rule. Some fast-drying paints, such as Benjamin Moore Aura, are designed to be used with the cut-in allowed to dry first. Additionally, the method of cutting in and rolling can vary depending on personal preference and the specific project. Some painters prefer to cut in first, while others roll first and then cut. Ultimately, the key to achieving a professional finish lies in maintaining a wet edge, working efficiently, and using quality tools and paints.

Flat and eggshell finishes are more forgiving
Eggshell paint, on the other hand, has a slight gloss and is easier to maintain than flat paint. It reflects some light and may highlight imperfections on a wall. However, it is more washable than flat paint and resists stains and scuffs. It is also more durable and can withstand frequent washing and minor stains.
Flat paint is often used to hide imperfections in drywall. It is also a good option for textured walls and ceilings. If you are a novice painter, flat paint will not show your inexperience as much.
Eggshell paint is more commonly used in high-traffic areas that are prone to moisture, grease, and dirt, such as kitchens and bathrooms. It is also a popular choice for painting trim and crown molding. If you are hiring professional painters, they will have the skill to apply eggshell paint without showing roller or brush marks.
Ultimately, the choice between flat and eggshell paint depends on the specific needs and requirements of the project. Both options offer exceptional coverage and durability.

Satin, semi-gloss and gloss finishes require more care
While it is generally recommended that you let paint dry before cutting in, this is not always necessary, especially if you are using a paint that can be applied in thick coats. However, if you are using a paint with a satin, semi-gloss, or gloss finish, you need to be extra cautious. These finishes require more care because they are more likely to show imperfections and brush strokes, which can be accentuated if the paint is still wet when you cut in.
When working with satin, semi-gloss, or gloss finishes, it is crucial to ensure that the paint is completely dry before cutting in. This is because these finishes tend to form a harder surface as they dry, which can make it difficult to blend the edges smoothly if the paint is still wet. Cutting in too early can result in visible brush marks and an uneven finish, detracting from the desired smooth and uniform appearance.
To achieve the best results with these finishes, it is advisable to allow ample drying time between coats. Follow the manufacturer's recommendations for drying times to ensure optimal results. By giving the paint sufficient time to dry, you can create a smooth and seamless finish that showcases the beauty of satin, semi-gloss, or gloss sheens.
Additionally, proper preparation is key when working with these finishes. Before applying the paint, ensure that the surface is clean, dry, and free of any debris or imperfections that may impact the final result. A well-prepared surface will enhance the overall finish and ensure a more professional appearance. Taking the time to prepare and allow for proper drying will result in a high-quality and durable finish that accentuates the beauty of your chosen paint colour and sheen.
When applying the paint, use a high-quality brush or roller that is suitable for the specific finish. Follow the manufacturer's instructions for the recommended application techniques and tools. With the right preparation, tools, and drying time, you can achieve a flawless and elegant finish that highlights the unique characteristics of satin, semi-gloss, or gloss sheens. Remember, while it may require more patience and attention to detail, the extra care taken will be rewarded with a stunning and long-lasting finish.

Quick-drying paints may need a different approach
When using quick-drying paints, it is essential to work swiftly and efficiently to avoid the paint drying before you are finished. Quick-drying paints can be advantageous when pressed for time or needing to use the area shortly after painting. However, they require a different approach to avoid issues.
Firstly, it is crucial to prepare the room properly. Ensure good ventilation by opening windows or using fans to create consistent airflow. Airflow is essential in regulating temperature and humidity, which significantly impact drying time. Choose a warm, dry day for your project, as dry heat helps paint dry faster. If the humidity is high, consider using a dehumidifier or air conditioning to reduce moisture and speed up the drying process.
Additionally, the paint application technique matters. Apply thin, even layers of paint, as thicker coats take longer to dry and can result in an uneven or tacky finish. Use a paint roller for large, flat surfaces, as it distributes paint more evenly than a brush, reducing the risk of drips and overload. Work on one wall at a time, cutting in and rolling before the paint dries. If you are using a darker colour or working in an area with critical lighting, maintaining a wet edge may be crucial to achieving a seamless finish.
Quick-drying paints can be challenging to work with, but with proper preparation and technique, you can achieve successful results. Remember to follow the manufacturer's directions for specific drying and recoating times, as these vary among paint types.

Using a roller to blend edges
When it comes to painting, achieving a smooth and seamless finish is essential, and this is where the technique of "cutting in" comes into play. Cutting in involves painting along the edges and corners of a surface with a brush before rolling on the main coat of paint. This process helps to create a crisp and precise border, ensuring that the paint job looks professional and well-executed.
Now, let's delve into the question of whether it matters if the paint dries after cutting in. The consensus among painters is that it is generally best to avoid letting the cut-in paint dry completely before rolling. The primary reason for this is to maintain a "wet edge" between the cut-in and the rolled paint. By keeping the cut-in paint wet, you can create a seamless transition between the two areas, avoiding any noticeable lines or edges. This technique is especially crucial when working with glossy or satin finishes, as the higher sheen can accentuate any inconsistencies in texture or application.
However, there may be times when you intentionally let the cut-in paint dry before rolling. This approach can be beneficial with certain types of fast-drying paints, such as Benjamin Moore Aura, which are designed to be used in this manner. Additionally, if you are working with a partner, you may be able to maintain a wet edge by working quickly and completing one wall at a time before the paint dries.
Using a roller to blend the edges after cutting in is a crucial step in achieving a uniform finish. Here are some tips for using a roller to blend edges effectively:
- Choose the Right Roller: Select a roller that is suitable for the paint you are using and the surface you are painting. A smaller roller, such as a 4-inch mini roller, can be helpful for cutting in and reaching tight corners.
- Cut in First: Before rolling, use a small angled brush to cut in along the edges and corners, creating a crisp line. Leave the edges loosely brushed to facilitate blending.
- Roll While the Paint is Still Wet: As soon as you finish cutting in, start rolling the main area of the surface. This allows the two types of paint application to blend together more seamlessly. Work in smaller sections to ensure that the paint remains wet as you go.
- Blend Gently: With the roller, gently blend the cut-in paint and the rolled paint together, being careful not to overwork the paint. This technique will help create a smooth and consistent finish.
- Address Texture Differences: Brushes tend to leave a smoother finish, while rollers create a slightly bumpy or stippled texture. To minimize the appearance of texture differences, use a mini roller to knock down brush marks and create a more uniform texture.
- Thin Coats: Apply thin coats of paint rather than a thick coat to promote faster drying and a smoother finish.
By following these steps and techniques, you can effectively use a roller to blend the edges after cutting in, resulting in a professional-looking paint job with seamless edges.
