Painting over existing semi-gloss paint with a satin finish can update the look of a room and provide a more subtle sheen. Going from semi-gloss to satin does require some special preparation to ensure proper adhesion and achieve the desired results. With the right steps, you can successfully make the switch from semi-gloss to satin.
Overview of Paint Sheens
Before diving into the process of going from semi-gloss to satin, it helps to understand the difference between paint sheens.
Paint sheen or gloss refers to how reflective and shiny the dried paint is. It ranges from flat/matte on the low end to high-gloss on the high end. In between are eggshell, satin, and semi-gloss. The glossier the paint, the more durable and washable it is. However, higher gloss paints also accentuate surface imperfections.
- Flat/matte paint has no shine and absorbs light. It works well for hiding flaws but is harder to clean.
- Eggshell has a soft, velvety appearance with little shine. It’s easy to clean and great for homes with kids.
- Satin has a low luster, around 20-35% gloss. It resists staining better than eggshell.
- Semi-gloss has a medium gloss of around 35-70% and is very scrubbable and stain resistant.
- High-gloss is very shiny at 70-85% gloss. It’s most often used for trim and accent walls.
Satin vs. Semi-Gloss
Going from semi-gloss to satin will reduce the shininess and make the surface less reflective. Satin provides a subtler sheen than semi-gloss that many homeowners prefer for large surfaces like walls. It still resists staining fairly well.
Semi-gloss has a noticeably shinier, glossier appearance. It highlights flaws like nail holes and uneven drywall texture. The higher gloss makes it optimal for areas like kitchens and bathrooms that need heavy cleaning.
Satin is a better choice for living spaces where you want a smooth, uniform finish. The lower sheen doesn’t overwhelm the room. Semi-gloss can look too bold on large surfaces yet satin adds just enough glow.
Preparing Semi-Gloss Paint for Satin Paint
Proper prep work before painting satin over semi-gloss is crucial for success. Taking a few steps to prepare the existing semi-gloss paint will help the new satin paint adhere properly.
The first step is thoroughly cleaning the semi-gloss walls to remove any dirt, grease, or soap residue. Use a degreasing cleaner or ammonia-based cleaner for the best degreasing effects. Tackle any stained areas and rinse everything thoroughly after cleaning.
Allow the surface to fully dry before moving forward. Any moisture left on the walls will cause problems with paint adhesion.
Lightly sanding the existing semi-gloss provides roughness for the new satin paint to cling to. The glossy surface needs some mild abrasion for the best adhesion.
Use fine grit sandpaper, around 220 grit, so you don’t gouge the underlying paint too severely. Delicately go over the entire surface, just enough to scuff up the shine a bit and create tooth.
Clean up all sanding residue with a dry cloth once finished. You want a clean surface for painting. Wipe gently over the walls as well with a tack cloth.
As an alternate to sanding, you can use a liquid deglosser or bonding agent. These will etch the slick glossy surface and leave a rougher profile for painting.
Deglossers often contain ammonia, detergents, and mild abrasives. Apply a coat according to the product directions. Most can be rinsed off with water after they’ve done their job.
Bonding primers contain strong binders that grab onto glossy paints and give the new paint something to adhere to. KILZ and Zinsser both make reliable options.
Applying primer designed for high-gloss surfaces can take the place of sanding or deglossing. Primers like KILZ Adhesion High-Bond Interior/Exterior Latex Primer/Sealer can stick tightly to glossy paints and also hide some sheen differences.
Priming provides a fresh uniform surface for the new satin paint. If you have a significant color change, tint the primer to the new paint color for better coverage.
Be sure to use latex primer if the existing paint is latex, or oil-based for oil-based paint. Don’t mix them.
Applying Satin Paint over Semi-Gloss
Once you’ve properly prepped the semi-gloss walls, you’re ready to apply the new satin paint. Use a high-quality satin paint and follow good painting practices.
When selecting paint, choose interior satin latex paint with a volatile organic compound (VOC) level of 50 g/L or lower. Lower VOC paints are better for indoor air quality.
Top brands like Behr Premium Plus, Benjamin Moore Regal Select, and Sherwin-Williams SuperPaint have excellent satin finish options. Get the highest quality for best results.
Stick with latex or oil-based paint to match what’s already on the walls. The finishes should be the same.
It’s crucial to apply the satin paint properly over the semi-gloss for an even finish. Apply in long, steady strokes while maintaining a wet edge.
Work in 3-4 foot sections, cutting in edges first with a brush then quickly rolling the section. Blend areas together before moving on.
Use a quality roller cover with a 1/4 – 3/8″ nap length for satin paint. Keep pressure even and don’t overwork the paint.
Apply the paint generously to avoid any thin spots but don’t overload the roller and create drips either.
Number of Coats
Applying two coats of satin paint is best to hide the greater shine and gloss of the original semi-gloss paint. The second coat also ensures you have an even look.
The first coat acts as the primer and seals the surface. This coat will soak into the wall more. The second coat provides the final smooth, uniform finish.
Inspect the walls after one coat dries. If you see any inconsistencies in sheen or bleed-through, do a second coat. Two coats is ideal.
Let the satin paint dry fully between coats according to the manufacturer’s recommendations. Darker colors may need extra drying time. Proper drying prevents problems.
Cool, dry conditions and adequate airflow will help accelerate the drying between coats. Don’t rush the process.
Once the second coat has dried completely, you can furnish the room again and enjoy the new satin finish.
Potential Issues Painting Satin over Semi-Gloss
Switching from semi-gloss to satin paint can sometimes present certain challenges. Being aware of these potential issues can help avoid problems.
Because satin has a lower sheen than semi-gloss, the original glossy paint may cause some bleed-through and inconsistencies in the new finish. The semi-gloss undertones can reflect through the satin topcoat.
This is why proper sanding/deglossing and applying two full coats of satin is important for full coverage. A quality primer also helps prevent bleed-through.
Flashing & Lap Marks
The glossiness of the original paint can also lead to flashing or lap marks as you apply the new satin paint. This happens when the overlap between sections is visible.
To avoid lap marks, maintain a wet edge and work in larger sections. Roll over edges to blend before moving on. Consistent application pressure also prevents flashing.
Skipping proper prep work can lead to the new satin paint not adhering correctly. Flaking or peeling paint is the result. Always clean, scuff sand, use a deglosser or primer for the best adhesion.
Oil and latex paints don’t bond well to each other either. Make sure to paint latex over latex and oil-based over oil-based.
Applying the satin paint too thinly over the semi-gloss can lead to an uneven finish. The semi-gloss will reflect through in some spots more, creating a blotchy appearance.
Putting down an adequate film build with two coats ensures an even satin sheen. Thin spots in the paint reveal the semi-gloss undertone.
Can I Paint Satin Over Gloss Without Sanding?
Many people wonder if it’s absolutely necessary to sand or degloss prior to painting satin over semi-gloss. The short answer is no, it is not completely required in every case.
However, sanding and deglossing are still highly recommended preparation steps for the most successful results.
You can sometimes get away without sanding or deglossing if:
- The existing semi-gloss paint is very new – less than a year old.
- You use a high-quality primer or bonding paint specifically designed for glossy surfaces. These create plenty of tooth for adhesion.
- You don’t mind some minor sheen irregularities or minimal bleed-through. The new satin won’t cover as evenly without sanding.
- Your walls don’t have any flaws for the glossy paint to highlight. The semi-gloss will showcase imperfections.
- You apply satin in very thin coats to slowly build up the flatter finish. Multiple sheer coats are needed.
However, there is a greater risk of adhesion failure down the road without sanding and deglossing first. For the best, long-lasting results, take the time to prepare the surface correctly.
Can You Put Satin Finish Over Gloss?
Just as with painting satin over semi-gloss, you can also apply a satin paint finish over high-gloss paint. The same adhesion rules apply.
High-gloss paint has an extremely smooth, shiny surface that latex paint can struggle to bond to. Scuff sanding, deglossing, or priming first gives the satin paint something to cling to.
It takes extra prep work and care to make the switch from gloss to satin look seamless. Take measures to avoid an uneven finish.
Make sure to use compatible paint types and apply multiple satin coats for full coverage and an even sheen. Proper application technique also prevents flashing.
In most cases, you can successfully paint over gloss with satin as long as you properly prepare the slick surface first before painting.
Can I Paint Matte Over Semi Gloss Paint?
Painting over semi-gloss with a matte or flat finish is very similar to applying satin. The same rules and preparation work apply.
Matte paint offers the lowest sheen possible, while semi-gloss has quite a bit of shine and reflectivity. You’ll want to take steps to ensure proper adhesion.
Lightly sanding, cleaning, and applying primer will all help new flat paint grab onto the glossy surface and cover evenly.
Use a premium quality matte paint and work carefully to get a smooth, consistent low sheen rather than uneven spotting.
It may take an extra coat or two of matte paint to fully hide the semi-gloss sheen compared to a satin finish. But with proper prep and application, you can achieve the flatter look you want.
Does Satin Paint Look Darker Than Semi-Gloss?
An interesting effect that sometimes occurs when going from semi-gloss to satin paint is the satin color may appear slightly darker or richer in tone.
There are a few reasons this can occur:
- The flatter finish absorbs more light so the tone looks deeper. Semi-gloss reflects light.
- Imperfections in the walls show more in satin, creating dark spots. Glossy paint hid flaws.
- The base color was not adjusted to account for the sheen difference. Lighter bases are used to offset flatter finishes.
To avoid a drastic color shift when switching sheens, have a paint store match the color in the new satin finish rather than just buying the same colored satin. Or use an actual chip of the color.
This will account for the way the light reflects differently in satin. You’ll get a true match.
With the color properly matched and walls prepped properly, you can paint over semi-gloss with satin paint for a beautiful updated look. Pay attention to prep work, application techniques, and coating evenly for the best results. The small amount of extra effort pays off in the end.
