Painting a wall can be a tedious task, especially when it comes to applying the second coat. The second coat is essential for a smooth and consistent finish, as it covers any spots missed during the first coat. To achieve the best results, it is recommended to use a roller tray instead of dipping the roller directly into the paint can. This ensures the roller is properly loaded with paint and avoids overloading, which can cause the roller to slide instead of roll. Before starting the second coat, it is crucial to clean the surface gently and use painter's tape to protect any areas that don't need to be painted. It is also important to keep track of the painted areas to ensure a consistent application. Starting at the top corner of the wall, cut in along the trim with an angled brush, then roll the paint on in small sections, forming a 3-foot-wide W and filling it in. Additionally, mixing the paint frequently is necessary to avoid streaks or variations in colour.
| Characteristics | Values |
|---|---|
| Number of coats | Two coats are recommended for optimal coverage and finish, with the first coat for colour/coverage and the second for finish. |
| Paint type | The number of coats depends on the type of paint. Flat paints may only require one coat, whereas sheen finishes may require more than one coat, depending on the condition of the wall. |
| Paint application technique | Roll the paint in small sections in the form of a 3-foot-wide "W" and then fill it in. Finish one wall before moving on to the next to avoid skipping sections. |
| Paint preparation | Mix the paint frequently to avoid streaks or variations in colour. |
| Paint storage | To prevent paint from drying out, cover paint brushes and rollers with plastic wrap, ensuring the plastic touches the bristles/roller, and store in the refrigerator. |
| Surface preparation | Before applying the second coat, use painter's tape and gently clean the surface of the wall with a clean cloth or sponge dampened with warm water and mild detergent. |
| Roller storage | To store a roller between coats, wrap it in cling wrap or a plastic bag and store it in the refrigerator to prevent the paint from drying. Do not let the roller sit in the paint to avoid overloading it. |
What You'll Learn
Ensure the first coat is dry before applying a second
It is important to ensure that the first coat of paint is completely dry before applying a second coat with a roller. This is because most coloured paints appear brighter when wet, so waiting until the paint is dry will make it easier to see where you have applied the second coat and where you have not. If you apply a second coat too soon, you may end up with darker spots where you have applied more paint than necessary.
The time it takes for the first coat to dry will depend on various factors, including the type of paint used, the thickness of the coat, and the humidity and temperature of the room. In general, it is recommended to wait at least several hours, if not overnight, before applying a second coat of paint. To speed up the drying process, you can use a fan or a dehumidifier in the room.
While waiting for the first coat to dry, it is important to properly store your paint roller to prevent the paint from drying on the roller. This can be done by wrapping the roller in cling wrap or foil and storing it in the refrigerator. Alternatively, you can place the roller in a tray and cover it with a plastic bag to keep the air out.
Once the first coat is dry, you can begin applying the second coat using a roller. Start by cutting in along the trim and edges with an angled brush, then use the roller to fill in the rest of the wall. It is important to work in small sections and to maintain a wet edge to avoid visible brush marks and uneven paint distribution.
By following these steps and allowing the first coat to dry completely before applying a second coat with a roller, you can achieve a high-quality and consistent paint finish.

Use a roller tray to avoid overloading the roller
Using a roller tray is an important step in ensuring that your roller is not overloaded with paint. Overloading your roller can cause paint drips and make it difficult to apply the paint evenly.
To use a roller tray effectively, start by filling the tray with about one inch of paint. Then, gently place the roller into the paint, using short strokes and slowly moving the roller around. Be sure to touch the paint's surface without fully submerging the roller. This will help distribute the paint evenly across the roller sleeve.
Once the roller is well-coated, use the ridges or ramp of the tray to remove any excess paint. Roll the roller up the tray, pressing out any extra paint. This step is crucial in avoiding overloading the roller and ensuring a smooth and even application.
By using a roller tray, you can control the amount of paint on the roller and achieve better results. It may seem like a small detail, but it makes a significant difference in the painting process and the final finish.

Wrap the roller in plastic wrap to prevent paint drying
If you need to take a break from painting and want to reuse your roller later, wrapping it in plastic wrap can prevent the paint from drying out. This method is best for breaks shorter than a day.
First, ensure that the roller is wet before wrapping it. Then, take the plastic wrap and cover the roller's entire nap, or spongy portion. You may need to wrap the plastic around the roller a couple of times to ensure that it is completely covered. This process is easier if you remove the roller from the handle.
Once the roller is wrapped, store it in a cool place. It is now ready to be reused within the next 24 hours.
If you need to store the roller for longer than a day, consider wrapping it in aluminium foil instead of plastic wrap. The foil retains a better seal, keeping the roller moist for a more extended period.

Start at the top corner of the wall and work in small sections
When applying the second coat of paint, it is important to start at the top corner of the wall and work in small sections to ensure a consistent finish. Using an angled brush, begin by cutting in along the trim and edges. This will help you achieve a clean and precise application.
Once you have cut in a small section, it's time to roll on the paint. Roll the paint on in a 3-foot-wide "W" pattern and then fill it in. This technique will help you achieve even coverage and avoid any streaks or uneven textures. It is important to work in small, manageable sections to ensure that the paint is applied consistently and that you don't miss any spots.
As you work, be mindful of your surroundings and use painter's tape to protect any areas that you don't want to get paint on. It is also important to mix the paint frequently, especially if you are using rich colours like red or dark blue. Paint with a high pigment concentration can settle at the bottom of the can, resulting in a slightly different tone for your second coat.
By starting at the top corner and working in small sections, you can take your time and ensure that each section is properly coated before moving on. This methodical approach will help you achieve a high-quality and consistent finish for your painting project. Remember to finish one wall before moving on to the next to avoid any skipped sections.

Mix the paint frequently to avoid streaks or colour variations
When applying a second coat of paint with a roller, it is important to mix the paint frequently to avoid streaks or colour variations. This is because the paint may start to separate, with the pigment settling at the bottom of the can, resulting in a non-uniform colour. By mixing the paint regularly, you ensure that the colour remains consistent throughout the painting process. This is especially important if you are using rich colours like red or dark blue, as these colours are more likely to show any variations.
To avoid streaks and colour variations, it is recommended to pour the paint into a large container before beginning to paint. This allows you to mix the paint thoroughly and create a consistent colour. If you are using multiple cans of paint, it is also important to mix the contents of each can together to ensure that there are no slight differences in tone between them.
Additionally, it is essential to work efficiently and avoid letting the paint sit for too long. The longer the paint sits, the more likely it is for the pigment to settle, which can lead to colour variations. By mixing the paint frequently and working at a steady pace, you can help ensure that your second coat of paint is applied evenly and consistently.
It is also a good practice to start painting from the top corner of the wall and work your way down in small sections. This helps you keep track of the areas you have already painted and ensures that you do not skip any sections. By following these tips and mixing your paint frequently, you can achieve a smooth and uniform finish on your walls without any streaks or colour variations.
