Painting a stainless steel sink is an easy and affordable way to update the look of your kitchen. With the right preparation and paint, you can transform a worn-out stainless steel sink into something that looks brand new. This comprehensive guide will walk you through everything you need to know to paint a stainless steel sink successfully.
Can You Paint a Stainless Steel Sink?
The short answer is yes, you can paint a stainless steel sink! While stainless steel is a durable material, over time sinks can become faded, scratched up, and just plain unattractive. Rather than investing in an entirely new sink, painting allows you to refresh your existing sink on a budget.
Paint adheres to stainless steel just like it would adhere to other surfaces such as wood, drywall, or plastic. With proper preparation and application, paint will bond to the stainless steel and create a “new” sink. Virtually any color of paint can be applied to create the exact look you want.
Painting can work on stainless steel sinks as well as enameled steel sinks. It is also possible to paint acrylic/composite sinks using this same process. Painting is an affordable DIY kitchen upgrade that makes a big visual impact.
Supplies Needed to Paint a Stainless Steel Sink
Painting a sink is largely about proper preparation. Gathering the right supplies is the first step to ensuring the paint will adhere correctly and provide long-lasting results:
- Sandpaper – Coarse 80-100 grit to scuff up the surface and 220-400 grit for smoothing
- Painters tape – For masking off faucet and edges
- TSP substitute cleaner – To remove grease and provide adhesion
- Rags and tack cloth – For cleaning the surface
- Paint primer – Specifically formulated for metal
- Paint – Oil-based or latex enamels made for metal
- Foam rollers and brushes – For applying paint
- Drop cloths – To protect surrounding surfaces
- Paint respirator mask – For proper ventilation
Quality primer and paint are the most important supplies for the job. The other items help keep the workspace clean and aid in surface preparation.
Step-by-Step Guide to Painting a Stainless Steel Sink
With the right supplies gathered, you are ready to tackle the sink painting process step-by-step:
1. Clean and Prepare the Sink Surface
Thorough cleaning is absolutely essential before painting. All grease, dirt, soap scum, minerals, and other contaminants must be removed for proper paint adhesion.
Use TSP substitute cleaner and a heavy duty scrub brush or pad to clean all surfaces of the sink including the basin, exterior walls, underside, and around the drain. Household ammonia is another good degreasing option.
Next, use 220-400 grit sandpaper to scuff up and rough up the sink surface. This gives the paint something to grip onto. Focus on the basin bottom and exterior sink walls.
Finish preparation by wiping down all surfaces with a tack cloth to remove sanding dust. The sink should now be chemically clean and physically abraded for paint.
2. Tape Off Areas Not Being Painted
Use painters tape to mask off the underside lip of the sink that touches the counter, the faucet fixtures, the strainer basket, and drain pipes. This protects these areas from getting accidentally painted.
Covering adjoining counter surfaces with drop cloths is also a good idea to prevent paint splatters and spills. Taping around the rim where the sink meets the counter creates a crisp paint line.
3. Apply Primer to the Sink
Priming the stainless steel before painting is mandatory for proper adhesion. The primer coat gives the topcoat paint something secure to bond to.
Use a high quality metal primer made for stainless steel. Rust-oleum and Krylon both make excellent primers for sinks and other metals. An epoxy-based primer is ideal for a stainless sink.
Read the primer directions closely and apply the correct number of thin coats, allowing proper drying time between coats. Primer is the foundation of your painted sink!
4. Paint the Sink
Once the primer has fully cured, you can apply the topcoat paint. Oil-based enamels and even latex paints work well on primed stainless steel. Buy a high quality paint made specifically for metal.
Just like the primer, apply thin even coats of the topcoat paint, allowing proper drying time between coats. 2-3 coats are usually needed for best coverage and color depth.
Use spray paint or apply with foam rollers and angled brushes. Combining methods leads to the smoothest finish. Maintain the spray can’s recommended distance from the surface.
5. Remove Tape and Reinstall Fixtures
After the final coat of paint has dried completely, use a utility knife to carefully remove all the painters tape from the sink edges and fixtures. Reinstall the sink strainer, drain pipes, faucet fixtures, and pipes.
Your sink should now have a vibrant new painted finish that gives your kitchen an updated look!
What Type of Paint Works on Stainless Steel?
Choosing the right type of primer and paint is crucial for getting great results painting a stainless steel sink. Look for these characteristics:
- Direct to Metal – Formulated to bond tightly to stainless steel and other metals.
- Appliance Enamel – High gloss durable finish made for kitchen appliances.
- Epoxy – Two part paints that cure to a hard, protective finish.
- Oil-based – Adheres well, more durable than latex.
- Acrylic Latex – Water-based, easier cleanup than oil-based.
- Automotive – Withstands heavy use, resists yellowing and cracking.
In addition to these types of paint, also consider the sheen level. Glossier paints are more durable for sinks than flat or matte. Semi-gloss is a good compromise.
Spray paint or brush-on enamel paints both work very well for DIY sink painting. Make sure to use only paints intended for metal for the best bond.
Popular Paint Color Choices for Sinks
While stainless steel is a popular sink finish, painted sinks allow you to choose virtually any color under the rainbow. Some top choices include:
- Black – A deep, dramatic black painted sink is very trendy. Use flat black for a matte look.
- White – Crisp and clean, white enamel paint matches any decor. Use high-gloss white for easy cleaning.
- Bronze – Warm bronze paint brings a vintage copper aesthetic. Layer metallic paints for depth.
- Silver – Mirrored silver paint adds shine and pairs well with chrome faucets.
- Antique Copper – Weathered penny copper paint looks timeworn and rustic.
- Gold – Shimmering gold paint creates an elegant, upscale look.
Beyond basic colors, you can also paint sinks with crackle effects, stone textures, faux finishes and more. Use your imagination and get creative with paint!
Will Paint Scratch or Chip on a Stainless Sink?
Painted sinks will hold up remarkably well to regular kitchen use. Quality preparation and using durable paints minimizes the chances of paint scratching or chipping over time. Here are some tips to help the paint last:
- Ensure proper surface cleaning, sanding, and priming to help paint adhere tightly.
- Use appliance, automotive, or direct-to-metal paint formulated for durability.
- Allow sufficient drying time between coats so paint fully cures.
- Apply 2-3 thin coats rather than 1 thick coat for better bonding.
- Avoid abrasive scouring pads and harsh cleansers that can wear the paint.
- Spot fix any scratches or chips with touch up paint to prevent further damage.
With careful use and occasional touch ups as needed, a painted sink can look fabulous for years before needing a repaint. Proper prep work is key to paint that withstands heavy use.
Can You Paint a Stainless Steel Sink Black?
Painting a stainless steel sink black is one of the most popular color choices. The bold, dramatic look pairs well with many kitchen designs from modern to traditional.
To paint a sink black, first prepare the surface thoroughly and apply a metal primer as outlined above. Allow to dry fully.
Then apply 2-3 coats of a flat or semi-gloss black enamel paint formulated for metal and appliances. Choose a premium quality paint from Rust-oleum, Krylon, or Valspar.
Use thin, even coats. Let dry fully and cure between coats. Remove tape and reinstall fixtures once final coat is dry.
Avoid “appliance black” spray paints – these have a mottled finish. Opt for a solid black with no speckling for best results on a sink.
The end result will be a deep, dark black that provides an eye-catching focal point in your kitchen!
Will Paint Prevent Stainless Steel From Rusting?
Stainless steel contains chromium, which gives it anti-corrosive properties and makes it resistant to rust. Painting over stainless steel will not impact that rust resistance.
The paint forms a protective barrier preventing oxygen and water from contacting the stainless steel surface underneath. As long as the paint remains intact, the stainless steel will be shielded from rusting.
If the paint were to chip or scratch down to the metal over time, that exposed spot could potentially rust since it is no longer protected by the chromium in the alloy. However, this is highly unlikely with proper paint application and touch ups.
So in summary, painted stainless steel should not rust. The paint will not degrade or negate the inherent anti-rust properties of stainless steel. Just take care to keep the paint coat intact.
How Durable and Long-Lasting is Paint on Stainless Steel?
With proper preparation and application, paint can actually adhere very well to stainless steel and provide a durable coating that lasts for years. There are two factors to durability:
Thorough cleaning, sanding, and priming allows the paint to grip tightly to stainless steel. If the surface is glossy, paint may slide right off. Proper abrading gives texture for the paint to key into.
High quality direct-to-metal paints provide maximum adhesion and hardness to resist wear and tear. Appliance enamels have been engineered for heavy use and durability.
Under heavy use, some chipping or scratching may occur over time. This can be easily touched up with more paint. With care and touch ups, a painted sink should maintain its beauty for 3-5 years or longer before needing a repaint.
Proper prep work is the foundation for durable, long-lasting paint on stainless steel. Combine this with a premium quality paint, and your sink can look freshly painted for years!
Can You Remove Paint From a Stainless Steel Sink?
If you decide to go back to a stainless finish in the future, paint can be removed from a stainless steel sink. It will take some work, but it is doable. Here are some ways to remove paint from stainless steel:
- Sandpaper – Coarser grits like 80-100 can grind paint away. Use finer grits to polish the steel.
- Paint stripper – Chemical strippers help soften and lift paint so it can be scrubbed off.
- Steel wool – Grade #3 or #4 works well to scour off paint.
- Razor blade – Carefully scrape paint away, taking care not to gouge the steel.
- Abrasive pads – Products like Scotch-Brite help abrade away paint.
Test products first on a small area to ensure they do not damage the stainless steel underneath. With some elbow grease, the original stainless finish can be uncovered again.
Professional Sink Painting vs DIY
While a DIY painted sink is certainly doable, you can also hire pros for an even more durable finish:
- Powder coating – This process electrostatically sprays powder that is then baked on for an ultra-hard finish.
- Epoxy coating – A two-part poured epoxy is applied for amazing adhesion and scratch resistance.
- Porcelainizing – Fired on porcelain enamel creates a smooth glass-like finish.
These professional processes generally hold up better long-term than DIY painting and are well suited for heavy use sinks. But they come at a higher cost – often over $200.
For the budget-minded, DIY spray paint or enamel still performs admirably. With care and occasional touch ups, a homemade painted sink can still look fantastic for years before needing redone. Proper prep work makes all the difference.
