Painting A Glossy Black Room - Five Tips To Avoid The Pitfalls

Floating wooden shelves and glossy black paint in powder room

There's nothing more dramatic than painting the walls of a room shiny black to make a bold statement in your home.

Black is a beautiful and versatile color, one of the best background colors when you want art or accent pieces to pop.

Contrary to popular belief, painting a room in a glossy black finish doesn't turn it into a small black cave. Light bounces off shiny black walls making the room look even bigger.

There's a downside, however to the glossy black paint treatment when it comes to hiding marks, scuffs, or repairs done to the wall. It will show most imperfections on the wall.

That's something I learned during the makeover of my powder room where I decided to give the small room a shiny black treatment in Sherwin Williams Tricorn Black in a satin finish.

Yes indeed, plenty of lessons that I'm here passing on to you if you ever decide to give one of your rooms a gorgeous glossy black finish.

I compiled all that learning experience into these five basic tips you can use to ensure success!

1. PATCH AND REPAIR HOLES AND WALL IMPERFECTIONS


The first step you have to take when wanting to paint a room black is to go all around the room and mark every single imperfection on the walls and fix them!

Black walls are very unforgiving when it comes to imperfections. Every single mark or drywall chip will show up in the final coat and they can be difficult to touch up or paint over.


Popped Nails 

I had a multitude of popped nails that I had to get rid of.  The nails were replaced with screws and then the area was patched.

2. FEATHER THOSE PATCHED EDGES


Feathering drywall is a technique that uses the angle at which you maneuver the blade of a drywall knife so that you don't leave a thick edge on the compound you just applied.  Those patched edges need to have a smooth transition onto the drywall.

Feathering is an easy concept, but it definitely takes some time and lots of practice to master.

I'm still a rookie at this business of patching walls. I failed miserably at patching so many areas in this little bathroom. 

I had to go three and even more times over the same area to make it as seamless as possible. Don't forget that we are preparing the wall for an unforgiving shiny dark final coat. ;)

Sand & Clean 


If the feathering went right, you're going to have a very smooth surface that would only need a light sanding and dusting to get it ready for paint.

3. EVEN OUT THE TEXTURE ON THE DRYWALL


When patching painted drywall you're going to end up with an area that is smoother than the rest of the painted drywall, as you can see in the picture above.

The difference in texture is going to be carried even after the final coat is applied and isn't going to look too pretty. You need to address that issue at this point.

Wall Texture Spray


If you're patching a few holes or a small area, you can use a wall texture spray. Make sure you shake the container well enough and practice your spraying pattern on a cardboard or practice surface before working on your walls. 
You can also adjust the spraying nozzle to deliver the texture in a fine, medium, or heavy consistency. It is recommended that you work with a fine coat and build it up.

Use The Proper Roller Nap


When you're dealing with many smooth patches all around the room as I was dealing with, your best bet is to address that difference in texture by applying the primer with the right type of roller nap.

Have you noticed those numbers (3/8", 1/4", 1/2") when buying paint rollers?

That number represents the nap height which is the thickness of the fibers that extend from the roller backing and carry the paint onto the walls.  3/16" or 1/4" would give you a smooth painted surface. while a higher nap, 3/4" or 1" is ideal for painted textured plaster, stucco, etc.

Select a nap height that matches the texture on the painted wall. Give the wall at least two coats of primer to even out the texture on all the surfaces.

Apply the first coat of primer and wait 24 hours before applying the second coat to give the product ample time to cure.


For my walls, I used a 1/2" nap height giving them two coats of primer. In hindsight, I should've given them one more coat.


4. PRIME THE WALLS


Primers cover imperfections on the walls, hide stains and prevent them from bleeding through the new paint. They give you a blank canvas where the paint will have a stronghold.

When working with patched or repaired drywall it is imperative to use a coat or two of good quality primer to prepare the wall for the topcoat.

I used white Kilz 2 Latex primer because that's what I already had at hand. If you're going from white to black as I did, I recommend getting a dark gray primer. It will bring the color closer to that of the final coat, perhaps lowering the number of topcoats you need to apply.

As stated in the previous tip, use the nap height that's a perfect match for the texture you have on most of your painted surfaces.


5. PAINT


The final step is to give those walls at least two coats of a shiny black topcoat.

I used a 1/4" roller nap height for the topcoat application.



If you did a proper drywall prep work, once you're done applying that first coat of black paint you're going to see an overall smooth finish. You just need to wait for the paint to dry to apply the next coat. Give it a third coat if the coverage isn't that great and you're DONE!


On the contrary, if you did a lousy job prepping those walls for paint, you need to go back to step one and repeat every single step to ensure a smooth, glossy black final coat.


Oh my goodness, I failed miserably at the task of patching those holes. I need to go back to feathering school to get all the tricks and hacks to ensure a smooth transition from one side to the other.

This area where we removed the previous light was the worst. Perhaps the light shining right on top of it was the main culprit. Every single imperfection there was showing.

The patched popped nail holes on the main wall weren't any better. I had to do lots more sanding.

Also, be aware that shiny black walls are difficult to touch up or paint over. Yep. I also tried to do that. I went over a small area with a paint-loaded roller.  Well, once it dried, that area was all that my eyes could pay attention to. It created a big black patch on the wall. The solution was to paint the entire wall one more time.



I still see a little difference in texture from the patched sections to the rest of the walls. That's precisely why I said I should've given it another coat of primer.

Even though the painting of this room was fully packed with learning mistakes, I'm very happy with the final outcome and I'm more than ready to tackle any other black room that comes my way.

  1. Thanks for sharing these tips with us. Sometimes bloggers make it look like everything works out perfect when it doesn't. Thanks for being so transparent with us. It helps to know what to expect and that not everything will be magazine worthy up close.

    BTW, I love how your bathroom came out. Looks gorgeous!

    1. All those mistakes along the way are a great learning opportunity. It sucks when you're in the middle of that, but they make us better crafters.
      I always say that my projects are far from perfect. By showing up those mistakes I hope that you can avoid them or be more prepared when dealing with the same situation.
      Thanks so much for stopping by and for your kind message!

  2. Patching sheetrock is tough...sadly I have become a master at it the last few years! One suggestion...after you have sanded SUPER smooth but before texture, take a damp sponge or cloth and wipe the edges of the mud...this helps get a good "feather" by removing new mud and revealing the original texture and gives you a seamless "transition" line. Try to get as close as you can to the patch without actually getting on the patch...let it dry and then lightly hit it again with sand paper. The sanded patch MUST be super smooth before you add texture or you will see the whole mess!!!
