Painting over gloss without sanding can be done, but it is not always effective. Gloss paint is known for its smooth and shiny finish, which can create a challenge when trying to apply a new coat of paint. If you want to ensure that your new coat of paint adheres properly, lightly sanding the surface before painting is usually recommended. This helps create a rough surface for the new paint to stick to. However, some alternatives to sanding include using a good adhesion primer, such as a super grip primer, or a deglosser, which can help prepare the surface for the new paint without the need for sanding.

What You'll Learn
Using a primer can help paint adhere to gloss surfaces
Painting over gloss without sanding is possible, but it can be tricky to get a clean and consistent finish. If you want to skip the sanding step, using a primer is essential to help the new paint adhere to the surface.
A super grip primer is recommended when painting over gloss with emulsion paint. This type of primer will help the new paint stick to the surface and provide a clean finish. It is especially important when painting surfaces like cornices, walls, or wallpaper, which tend to be more visible and require a smoother appearance.
If you are painting over gloss with another type of paint, such as satin or eggshell, you may not need to use a primer. However, lightly sanding and cleaning the surface is still recommended to remove the glossy finish and provide a good base for the new paint to adhere to. A quick rub with fine sandpaper (around 240 grit) should be sufficient to roughen the surface and promote adhesion.
In some cases, an adhesion primer may be necessary even after sanding. This is especially true if you are painting over a surface that has been coated with oil-based paint, as it can be challenging to get new paint to stick to it.
By using a combination of light sanding and a suitable primer, you can successfully paint over gloss without the need for extensive surface preparation. This method will save you time and effort while still achieving a clean and durable finish.

Lightly sanding gloss surfaces can help paint stick
Painting over gloss without sanding is possible, but light sanding will help the new paint adhere and result in a better finish. Gloss surfaces are smooth and glass-like, and there is nothing for new paint to adhere to, so it will slide around and the shininess of the gloss will eventually show through.
Lightly sanding gloss surfaces with fine sandpaper (around 240 grit) will roughen the surface and provide a good key for the next coat of paint to stick to. This is especially important if you are painting over gloss with emulsion paint, as emulsion will not be durable enough for surfaces that have to stand up to wear and tear, like skirting boards, doors, and door frames. In this case, you should use a super grip primer to prepare the surface before painting with emulsion. If you are painting over gloss with another coat of gloss, satin, or eggshell paint, you can lightly sand and clean the surface and paint without using a primer.
If you do not want to sand, you can use an adhesion primer to prepare the surface for painting. If you want to ensure that your future coating will last, it is not recommended to skip this step. If you are painting over oil-based gloss, you will likely have adhesion problems with a variety of products, so it is important to use a good adhesion primer. If you are painting over latex gloss, most primers will be fine. It is helpful to know whether your current coating is latex or oil-based, as very few latex paints settle well in a gloss finish.
In some cases, it is not necessary to sand between coats of paint. For example, when using products like Kilz or Zinsser 1-2-3, you can simply prime, let dry, and then paint. However, some sources recommend lightly sanding between coats of high-gloss paint, as "shiny doesn't stick to shiny," and a tiny amount of sanding will improve adherence. Sanding between coats is considered an advanced technique that can improve the outcome of your project and result in an excellent finish.

Gloss paint will not stick to unprepped surfaces
Gloss paint will not adhere to unprepped surfaces. Gloss paint is known for its smooth and shiny finish, and when attempting to paint over it without proper preparation, the new paint will not have a textured surface to grip onto and will struggle to adhere. This is especially true if you are trying to paint over gloss with a regular matt emulsion, as the new paint will just slide everywhere and the shininess of the gloss will eventually resurface.
There are a few ways to prepare a gloss surface for new paint. One option is to sand the surface, creating a rough texture that will help the new paint adhere. This can be done with fine sandpaper or by using a technique called wet sanding, which is useful when working on surfaces with intricate details like doors. However, sanding can be time-consuming and labour-intensive, especially when covering large areas or surfaces with intricate grooves.
An alternative to sanding is to use a primer designed for glossy surfaces, such as a super grip primer or an adhesion primer. These primers provide a better surface for the new paint to stick to, and they can be used with various types of paint, including emulsion and satin finishes. It is important to note that the effectiveness of the primer may vary depending on the type of paint already on the surface. For example, if the existing paint is oil-based, you may encounter adhesion problems with certain primers.
In some cases, a combination of light sanding and priming may be recommended to ensure the best adhesion for the new paint. Additionally, it is always a good idea to clean the surface thoroughly before painting to remove any grease or dirt that could interfere with the paint's adhesion.
Overall, while it is possible to paint over gloss without sanding, proper surface preparation is crucial to ensure the new paint adheres correctly and that your desired finish is achieved.

Deglossing solutions can be used instead of sanding
Painting over gloss without sanding is possible, but it is not recommended as the new paint will not adhere to the surface and will not have a lasting finish. If you want to avoid sanding, you can use a deglosser, also known as liquid sandpaper, which is a chemical solution designed to remove the glossy finish from surfaces without the need for physical sanding.
Deglossing solutions work by breaking down the top layer of the finish on painted or varnished surfaces, creating a dull, roughened texture that allows new paint or finishes to adhere more effectively. They are ideal for small touch-up jobs or quick refreshes, as they can be quickly applied with a cloth or brush and are ready for painting in minutes. Liquid sandpaper can easily reach intricate details and crevices that might be challenging to sand manually, making them great for preparing surfaces with complex designs or hard-to-reach areas.
When using a deglosser, it is important to take the necessary safety precautions as they contain chemicals that can be harmful if inhaled or if they come into contact with your skin. Be sure to work in a well-ventilated area or outdoors, and use breathing protection, chemical-resistant gloves, and eye protection.
While deglossers are a convenient alternative to sanding, they may not be suitable for all projects. If the surface has significant imperfections or if you need to remove a large amount of material, traditional sanding may be a better option. Additionally, some high-quality paints and finishes may resist deglossers, and sanding may be necessary to achieve the desired results.
Before using a deglosser on a surface, it is recommended to do a test run on a small area to ensure that it does not damage the surface and that the desired results can be achieved. If you are concerned about using chemicals, you may consider using eco-friendly alternatives such as vinegar and water solutions or trisodium phosphate (TSP) for light deglossing, although they may not be as effective as commercial products.

Surfaces should be cleaned before painting over gloss
Once the surface is clean, it can be sanded to create a rough texture that will help the new paint adhere. Sandpaper with a grit of 180 or 220 is often recommended for sanding gloss. After sanding, the surface should be wiped down with a damp cloth to remove any dust. If the surface is particularly dusty, a vacuum cleaner can be used instead.
If the surface is not properly cleaned and sanded, the new paint may not adhere properly and the old gloss finish may show through. This is especially true if the new paint is a matte emulsion, as this type of paint is not designed to adhere to glossy surfaces.
In addition to cleaning and sanding, priming the surface can also help to improve paint adhesion. A super grip primer is often recommended for surfaces that will be painted with emulsion paint. However, if the surface is made of wood, a wood primer is a better choice.
