Easy Ways To Fix Missed Spots When Painting With Semi-Gloss

Painting walls can be a tedious task, and it's easy to miss spots, especially when working with semi-gloss paint. This can result in an uneven finish with blotches, streaks, or patches of different sheen, commonly known as flashing. To fix missed spots, it is recommended to wait for the paint to dry completely before touching up the area with a brush. Using leftover paint ensures colour uniformity. However, it is essential to consider the lighting, as certain light conditions can accentuate imperfections, such as dark spots on wavy walls. Proper lighting during the painting process can help identify missed spots early on. Additionally, ensuring adequate primer coverage and using a well-loaded roller can prevent thin paint coverage and reduce the likelihood of missing spots.

How to fix missed spots when painting semi-gloss

Use leftover paint to touch up missed spots

When painting with semi-gloss, it is common to miss spots, especially in tight quarters. The best way to avoid this is to have a well-lit wall, but if you do miss a spot, you can use your leftover paint to touch it up.

Make sure to wait until the paint is completely dry, which usually takes about four hours. Then, use a small paintbrush to fill in the missed spots. Be careful not to go back over a line once you've painted it, as this can cause the paint to dry darker and create an uneven finish. If you're using a roller, try to use it for touch-ups as well, as this will help create a more uniform finish. However, this can be tricky with glossy paint, so you may need to apply a second coat of paint to the entire surface.

To avoid missing spots in the first place, make sure your roller is fully and evenly loaded with paint. Apply the paint in vertical lines that slightly overlap the wet edge, and refill your roller often. Using paint that is both paint and primer in one can also help to improve coverage and reduce the number of coats needed.

If you're touching up spots on a ceiling, use ceiling paint that matches the colour of your ceiling. If you're not sure of the exact shade, bring a sample to your local paint retailer to have it colour-matched.

Use a roller for touch-ups, especially with glossy paint

When it comes to fixing missed spots when painting with semi-gloss, one recommended approach is to use a roller for touch-ups. This is especially relevant if you used a roller for the initial coat, as using a paintbrush for touch-ups can leave visible brush marks on a rolled wall. Using a roller with the same nap size as the one used for the initial coat is crucial to achieving a consistent texture. However, touch-ups with a roller can be tricky, especially with glossy paint.

To ensure effective touch-up work, several conditions should be considered. Firstly, the existing coating should have a Gloss Level of either GL-1 (traditional flat finish) or GL-2 (traditional matte finish). Coatings with higher gloss levels are more challenging to touch up due to the increased visibility of variances in light reflectance. Secondly, the existing coating should be light in colour, as deeper or darker colours are generally harder to touch up successfully. Lastly, avoid critical lighting conditions, as touch-up work is more likely to be noticeable under intense lighting, even with a GL-1 coating.

It's worth noting that the best way to avoid missing spots when painting is to ensure your work area is well-lit. This will help you identify any missed spots before the paint dries. Additionally, applying a sufficient number of coats, typically two or more, can help create a uniform finish and reduce the appearance of missed spots.

While touch-ups with a roller can be challenging, it is possible to purchase rollers specifically designed for touch-ups. These rollers can help you achieve better results. However, it's important to remember that touch-up work may not always be possible, especially if the existing coating has a high gloss level or if the lighting conditions are unfavourable. In such cases, you may need to consider repainting the entire surface to achieve a consistent finish.

In conclusion, while using a roller for touch-ups on semi-gloss paint can be tricky, following the above recommendations can increase your chances of success. However, it's always a good idea to plan your painting project carefully and work in a well-lit area to minimise the occurrence of missed spots in the first place.

Avoid thin paint application, use a roller for a 2x2 section

When painting with semi-gloss, it is important to avoid thin paint application as it can result in an uneven finish with blotches and streaks. To achieve a smooth and uniform finish, it is recommended to apply multiple thin coats of paint instead of one thick coat. This allows for better adhesion and a true colour finish.

To avoid thin paint application, it is crucial to properly prepare the surface before painting. This includes cleaning the surface and sanding it if necessary to ensure smoothness and remove any imperfections. Filling in any gaps or holes with putty or spackle will create an even base for the paint to adhere to.

When using a roller, it is important to choose the right size and type for the specific surface being painted. For example, a narrow roller is typically used for painting trim, such as baseboards or window frames, to avoid brush marks and ensure a smooth finish. For larger surfaces, such as walls, a longer roller with an appropriate nap length can help achieve uniform coverage.

To ensure a consistent paint application with a roller, it is recommended to follow a specific technique. First, moisten the roller with water or the appropriate thinner, depending on the type of paint. Then, fill the roller pan to about half, dipping the roller and rolling it down the slope of the pan to saturate it with paint. The most effective technique for painting with a roller is to work in small sections, approximately 2-3 square feet at a time, using a zigzag pattern without lifting the roller from the wall. This helps to avoid leaving marks or creating lap lines.

By following these guidelines and techniques, you can avoid thin paint application and create a smooth and uniform finish with semi-gloss paint.

Use a small paintbrush for better control near borders

When fixing missed spots when painting semi-gloss, it is important to have better control near borders. One way to achieve this is by using a small paintbrush. Small paintbrushes allow for more precise application of paint and help avoid over-application or paint dripping onto unwanted areas.

Before starting to paint, it is important to establish the project's boundaries. Cutting in the edges will help create a neat border and ensure that the paint is applied only to the desired areas. This is especially important when working near ceilings, cornices, or other areas where the paint should not bleed into adjacent surfaces.

When using a small paintbrush for touch-ups, it is crucial to wait until the paint is completely dry. Touching up missed spots before the paint dries can disturb the surrounding area and create an uneven finish. Allow the paint to dry for at least 4 hours before applying additional coats or touch-ups.

For a consistent finish, it is recommended to use a paint and primer in one can. This type of paint contains more solids and binders, resulting in thicker coverage and better hiding of any missed spots or imperfections. Using a roller, fully load it with paint and apply it in vertical lines that slightly overlap the wet edge. This technique helps to avoid streaks and ensures a uniform finish.

Additionally, lighting plays a crucial role in identifying missed spots. Ensure the area being painted is well-lit to easily spot any areas that require additional attention. By combining good lighting with a small paintbrush, you can precisely touch up any missed spots and create a seamless finish.

Avoid over-thinning paint to prevent poor sheen uniformity

When painting, it is important to be mindful of the amount of paint you are using. Using too little paint can cause streaks, where paint is unevenly distributed on a wall. On the other hand, over-thinning your paint can cause poor sheen uniformity, which is easy to spot as it results in a combination of dull and shiny spots on the wall. This issue is more noticeable when looking at the wall from an angle or when light shines on the surface at an angle.

To avoid over-thinning your paint, make sure to prime or seal new surfaces before applying the topcoat. This will ensure a uniformly porous surface and a more uniform final coat. If you skip priming or do not adequately prime your wall before painting, you may end up with an uneven or blotchy finish.

Additionally, use enough paint to effectively cover the entire surface. Apply the paint with a soft, even rolling motion, and use a roller brush designed for the specific surface you are painting. Start by cutting in your edges to establish the project's boundaries and use a small paintbrush for better control near the ceiling-wall border.

If you do end up with missed spots or blotches, you can try to touch them up with a roller, but this can be tricky, especially with glossy paint. You may need to apply a second coat of paint to the entire surface to achieve a uniform finish.
