Do you want your kitchen cabinets to look modern, smooth, and refreshed, but you don’t want the grain to peek through? Hiring a professional should give you confidence, but many homeowners find themselves unsure if even the best painters can hide that natural texture. It’s frustrating, right?

By the end of this article, you’ll know exactly what to look for in terms of materials, methods, and products that can help cover oak grain and get the smooth look you’re after. We’ll break down the professional process of painting cabinets and discuss the best products for long-lasting, high-quality results.
Oak Grain on Kitchen Cabinets
Oak’s natural, open-pored structure is what gives it that beautiful, textured grain—but it’s also what makes it challenging to paint smoothly. Oak is a hardwood with wide-open pores and a rough surface texture.
- Open-Pored Grain: Oak’s large pores create a bumpy surface, which will remain visible if not prepared properly before painting.
- Absorption and Uneven Texture: Oak’s porous nature also absorbs paint unevenly, causing patches of grain texture to stand out more than others.
- Variations in Grain: Oak has natural highs and lows in its grain. If you paint without smoothing these out, that uneven texture becomes visible, even under layers of paint.
- Low-Quality Cabinet Paint Products: Low-grade or improper materials won’t get you a smooth, professional look, no matter how carefully you apply them. The best-quality brushes, sprayers, primers and paints, especially products like 2K polyurethanes, can significantly affect the end result by helping to fill and cover the grain for a polished look.
Step-By-Step Guide to Hiding Oak Grain
If you want smooth, grain-free painted oak cabinets, here’s how a professional would approach the project to get that finish.
1. Remove Doors, Drawers, and Hardware
We begin by removing all doors, drawer fronts, and hardware, taking these parts to our climate-controlled workshop for optimal conditions. A controlled environment helps us achieve the best finish while avoiding dust and humidity issues.
2. Thoroughly Clean Surfaces
Cleaning is critical. Oak cabinets, especially in kitchens, can accumulate grease and grime over time. We start with a strong, non-abrasive cleaner to remove oils that might prevent primer and paint from adhering well.
Denatured alcohol or specialized degreasers are ideal for prepping surfaces for primer.
3. Sand the Surface Smooth
Next, we sand the cabinets to smooth out the surface and reduce the grain’s prominence. This step is essential for creating a flat base.
We start with medium-grit sandpaper (around 120 grit) and finish with finer grit (up to 220 grit) to ensure the surface is ready to hold the primer smoothly.
Sanding won’t completely hide the grain on its own, but it does help reduce texture.
4. Prime with High-Quality 2K Polyurethane
This is where quality products shine. For oak cabinets, we recommend using a 2K (two-component) polyurethane primer. Unlike standard primers, 2K polyurethane primer has a chemical catalyst that cures the primer into a hard, durable finish.
This primer is specifically designed for durability, allowing it to hold up under kitchen conditions without peeling or fading. It was originally designed for floors and cars, so it has been groundbreaking for the wood-coatings industry.
Why 2K Polyurethane?: 2K polyurethanes provide exceptional adhesion, even coverage, and a thicker layer than a regular primer. It fills in remaining grain patterns and gives a smooth, hard surface for the final paint layers.
5. Spraying vs. Brushing the Cabinets
To achieve a professional-grade finish, spray painting is generally recommended for cabinets, especially for oak. Spraying avoids brush strokes and produces an even, factory-quality finish. At Brush & Roll Painting, we take doors and drawer fronts to our shop to spray them in a dust-free environment.
Spray Painting Cabinets: Spraying creates a quick, seamless finish that’s much harder to achieve with brushing or rolling. We use specialized spray equipment, which gives a smooth coat without texture. However, spray painting cabinet boxes does come with a lot of prep work to protect floors, countertops, walls, etc. which can take a while on its own. Otherwise, your kitchen will be a messy disaster.
Brushing the Boxes: In cases where it’s not feasible to spray in-home or you simply don’t want to deal with the mess, we carefully brush the boxes, using top-quality brushes and rollers to minimize brush marks. This is the most common option, as you can still use your kitchen throughout the process.
6. Apply 2-3 Coats of 2K Polyurethane Paint
We follow the primer with multiple coats of 2K polyurethane paint in the color you’ve chosen. Like the primer, 2K polyurethane paint is catalyzed for strength and durability. The 2K paint dries to a hard, protective finish that resists scratches, stains, and everyday wear.
Multiple Coats: Because oak cabinets need a thicker finish to cover any last traces of grain, we apply at least two coats, with a light sanding in between each layer. This helps build a durable, uniform layer that gives you that high-end, smooth look.
Curing: We allow proper drying and curing time between each coat to ensure the paint fully hardens.
Using 2K polyurethane paints is key to a smooth finish that holds up well over time. They bond tightly to the primer and provide a durable finish that’s easy to clean and maintain.
Can The Grain Show Through Painted Cabinets?
The grain can absolutely show through painted cabinets—especially if you’re working with oak if that is what you would prefer. It can add character and show the natural quality of the wood.
In the end, it comes down to personal preference, hiring a professional painter, and knowing what to expect from the process. No matter what look you’re going through with the grain, if you want a finish that lasts, thorough preparation and the right materials are essential.
