Introduction
Painting kitchen cabinets is a popular and affordable way to give your kitchen a fresh, updated look without the high cost of installing brand new cabinetry. However, it’s important to use the proper painting techniques and products to ensure a long-lasting, durable finish. One key question that often arises is whether you need to apply a top coat after painting cabinets for added protection and sheen. Below, we’ll explore the pros and cons of using a top coat on painted cabinets to help you determine if it’s the right choice for your kitchen refresh.
What is a Top Coat?
A top coat is a clear protective layer applied as the final step when painting cabinets. Top coats are formulated to provide extra durability, enhance the paint’s sheen and create a smooth, uniform finish. There are several different types of top coat products available:
- Polyurethane – Oil or water-based polyurethane is the most common top coat for painted cabinets. It dries to a hard, protective finish and is available in various sheen levels from satin to high gloss.
- Acrylic – Acrylic top coats dry quickly and are easy to apply. They provide good durability for high-traffic areas.
- Wax – Wax top coats like paste wax add a smooth feel and subtle sheen. Wax is easy to apply but requires more frequent reapplication than polyurethane or acrylic.
- Lacquer – Lacquer top coats offer a very smooth, durable finish. However, lacquer fumes are strong and require proper ventilation during application.
Should You Use a Top Coat on Painted Cabinets?
Using a top coat after painting cabinets has some advantages but also a few potential drawbacks to consider:
Pros of Using a Top Coat
- Adds a protective barrier against moisture, grease and daily wear and tear
- Enhances the paint’s sheen for a smoother, more uniform look
- Can minimize visible brush strokes in the painted finish
- Makes the finish more washable and easier to clean
- May help the paint last longer before needing to be redone
Cons of Using a Top Coat
- Adds time and cost to the cabinet painting project
- Risk of yellowing or discoloration over time on light paint colors
- Potential for bubbling if top coat is applied too heavily
- Difficult to patch if damaged; may require refinishing whole area
- Some top coat products have strong fumes requiring proper ventilation
Do Newly Painted Cabinets Require a Top Coat?
The short answer is no – applying a top coat is optional and comes down to your preferences in terms of the final look and feel you want for your painted cabinets. Here are some factors to help decide if a top coat is right for your kitchen:
- Cabinet Location – A top coat provides more protection for cabinets in high-use kitchens or bathrooms subject to moisture, grease splatters and frequent cleaning. It’s less critical for low-use areas.
- Paint Type – The durability of the actual cabinet paint factors into the need for a top coat. For example, 100% acrylic latex paints are quite durable on their own. Older paint types like alkyd enamel may benefit more from a protective top layer.
- Desired Sheen – Top coats in gloss, semi-gloss and satin sheens amplify the reflective qualities of painted cabinets. If you prefer a flat matte look, a top coat isn’t necessary.
- Budget – Top coats add cost in materials and time to the painting project. They’re ideal for high-end kitchen makeovers but may not fit every budget.
Best Practices for Applying a Top Coat to Cabinets
If you do opt to use a top coat when painting your kitchen or bathroom cabinets, follow these tips for best results:
Choose the Right Product
Select a top coat designed for use on painted cabinetry such as polyurethane, acrylic or lacquer. These provide better protection than basic polycrylic or varnish. Oil-based polyurethane is considered the most durable option.
Apply in Thin, Even Layers
The top coat should go on in smooth, thin layers following the manufacturer’s instructions. Applying too much product in one coat can cause drips, yellowing or an uneven look.
Lightly Sand Between Coats
Allow each coat to fully dry, then lightly sand with fine 220-grit sandpaper before applying the next layer. This helps each coat bond smoothly.
Seal Raw Wood Edges
Use a dewaxed shellac primer to seal any raw wood on the inside edges and undersides before applying the top coat. This prevents moisture damage.
Work in a Well-Ventilated Area
Polyurethane, lacquer and some acrylic top coats have strong fumes. Make sure the space is properly ventilated during application and drying time.
Consider Satin Sheen
Satin top coats hide imperfections in the painted surface better than high gloss. Glossy finishes also show dust and fingerprints much more.
Maintaining Painted Cabinets with a Top Coat
The top coat extends the life and good looks of painted cabinets. But no finish lasts forever, especially in heavily used kitchens. Here are some maintenance tips:
- Wipe up spills and splatters quickly to prevent stains.
- Wash cabinets periodically with a mild soap and water using a soft rag or sponge. Avoid abrasive cleaners.
- Reapply a fresh top coat every 2-3 years or when the finish becomes worn, dull or stained.
- Spot repair anychips or damage to prevent moisture getting under the top layer.
- If the finish starts peeling or needs complete refinishing, lightly sand cabinets before repainting.
Key Takeaways
- Top coats provide extra protection and sheen but are optional when painting cabinets.
- Consider factors like cabinet use, paint type and desired sheen when deciding on a top coat.
- Applying multiple thin, even layers ensures the best results.
- Proper prep work and maintaining the finish helps painted cabinets with a top coat last for years.
- Damaged top coat finishes can be spot repaired or completely refinished as needed.
Using a quality top coat and application technique allows you to get the most durability and aesthetic value from painting your cabinets. Consider your needs and expectations to determine if the added time and cost of a top coat is worth the investment for your kitchen update. With the right prep work and maintenance, your painted cabinets can maintain their like-new look and function for years before needing to be redone.
