Preparing Cabinets for Painting Over Chalk Paint
Painting over chalk paint requires careful preparation to ensure a smooth, durable finish. The porous nature of chalk paint means it can absorb subsequent layers unevenly, leading to an unsatisfactory result if not properly addressed. This preparation involves cleaning, sanding, priming, and filling imperfections – all crucial steps for a successful repaint.
Cleaning Chalk-Painted Cabinets
Thorough cleaning is the first step. Chalk paint, while beautiful, is prone to dust and grime accumulation. Use a degreasing cleaner, such as TSP (trisodium phosphate), diluted according to the manufacturer’s instructions. Apply with a soft cloth or sponge, rinsing thoroughly with clean water and allowing the cabinets to dry completely before proceeding. This removes any grease, dirt, or wax that might interfere with the adhesion of the primer and topcoat. Ignoring this step can result in peeling or flaking of the new paint.
Priming Chalk-Painted Cabinets
Priming is paramount when painting over chalk paint. Chalk paint’s high porosity requires a primer to create a uniform surface and prevent the new paint from being absorbed unevenly, leading to an inconsistent finish. A good quality bonding primer, such as Kilz Adhesion Primer or Zinsser BIN Shellac-Based Primer, is recommended. These primers are designed to adhere well to various surfaces, including previously painted ones. Apply the primer evenly using a high-quality brush or roller, ensuring complete coverage. Allow sufficient drying time before sanding. Applying thin, even coats is preferable to one thick coat which may drip or run.
Sanding Techniques for Chalk Paint, Painting over chalk painted cabinets
Sanding is crucial for creating a smooth surface for the new paint. For chalk paint, light sanding is generally sufficient. Start with a higher grit sandpaper, such as 220-grit, to remove any imperfections or raised areas. Then, switch to a finer grit, such as 320-grit, for a smoother finish. Avoid aggressive sanding, as this can damage the underlying chalk paint. Over-sanding can also lead to uneven surfaces. The goal is to create a slightly textured surface that provides better adhesion for the new paint. Using progressively finer grits minimizes scratches and creates a very smooth base.

Choosing and Applying the New Paint: Painting Over Chalk Painted Cabinets
Choosing the right paint and applying it correctly is crucial for a professional-looking finish when painting over chalk paint. The type of paint you select will significantly impact the final result, influencing durability, appearance, and the overall ease of application. Careful consideration of both paint type and application technique is essential for achieving a flawless, long-lasting finish.
Paint Type Selection for Painting Over Chalk Paint
Several paint types are suitable for painting over chalk paint, each with its own advantages and disadvantages. The best choice depends on factors such as the desired finish, the level of durability required, and your personal painting experience.
- Latex Paint: Latex paints are water-based, making them easy to clean up with soap and water. They offer good adhesion and are relatively low in odor. However, they may require multiple coats for full coverage, especially over dark chalk paint colors. Latex paints are available in a wide range of sheens, from flat to high-gloss, offering versatility in the final look.
- Oil-Based Paint: Oil-based paints offer superior durability and a harder, more resistant finish than latex paints. They provide excellent coverage and are less prone to chipping or scratching. However, they require mineral spirits for cleanup, have a strong odor, and take longer to dry. Oil-based paints are generally considered more suitable for high-traffic areas or surfaces that require exceptional protection.
- Acrylic-Alkyd Paint: Acrylic-alkyd paints combine the best features of both latex and oil-based paints. They offer the durability and hardness of oil-based paints but are water-cleanable like latex paints. They dry relatively quickly and have a low odor compared to traditional oil-based paints, making them a popular choice for many projects. However, they may be slightly more expensive than latex paints.
Paint Application Techniques
Proper application techniques are vital for achieving a smooth, even finish. Different techniques are best suited to different paint types and desired effects.
- Brush Application: A high-quality brush with synthetic bristles is recommended for latex and acrylic-alkyd paints. For oil-based paints, natural bristle brushes are generally preferred. Use smooth, even strokes, working in the direction of the wood grain. Avoid overloading the brush to prevent drips and runs. Multiple thin coats are better than one thick coat.
- Roller Application: Rollers are efficient for larger surfaces, but require a smooth, even application to avoid visible roller marks. Use a high-quality roller cover appropriate for the paint type. Apply paint in even, overlapping strokes, maintaining a wet edge to prevent lap marks. A good quality paint tray and roller grid are essential for even paint distribution.
- Spray Painting: Spray painting offers a very smooth, even finish, especially beneficial for achieving a consistent color and sheen across large areas. However, it requires proper ventilation, protective gear, and practice to avoid overspray and runs. Thinning the paint according to the manufacturer’s instructions is usually necessary for spray application.
Paint Color and Sheen Selection
The choice of paint color and sheen significantly impacts the overall look and feel of the cabinets and the room.
- Color Selection: Consider the existing décor, lighting, and desired mood when selecting a paint color. Warm colors like creams, yellows, and oranges create a cozy atmosphere, while cool colors like blues, greens, and grays provide a more calming effect. Neutral colors are versatile and work well with a variety of styles. Testing paint swatches on the cabinets in different lighting conditions is recommended before committing to a final color.
- Sheen Selection: The sheen of the paint affects the light reflection and the appearance of imperfections. Flat or matte sheens hide imperfections well but are more prone to staining and require more frequent cleaning. Eggshell and satin sheens offer a balance of durability and hiding power, while semi-gloss and high-gloss sheens are more durable and easier to clean but will highlight imperfections.

Troubleshooting and Finishing Touches
Painting over chalk paint can present unique challenges. Understanding potential problems and employing the right techniques is crucial for achieving a flawless, durable finish. This section addresses common issues and provides practical solutions for a professional outcome.
Addressing Common Painting Problems
Several issues can arise when painting over chalk paint. Peeling, for instance, often occurs when the chalk paint hasn’t been properly adhered to the surface or when the new paint is incompatible. Chipping, on the other hand, is usually a result of insufficient sanding or the use of a low-quality topcoat. Uneven texture is often caused by inadequate preparation, such as failing to fill imperfections or sanding unevenly. To prevent peeling, ensure the chalk paint is thoroughly dry and well-adhered before applying the new coat. A good primer can help to bridge any gaps and improve adhesion. For chipping, careful sanding and the application of a high-quality primer and topcoat are key. To address uneven texture, focus on thorough sanding and the application of multiple thin coats of paint. Remember, patience is key.
Achieving a Smooth, Professional Finish
A smooth finish is the hallmark of professional painting. To prevent brush strokes, use a high-quality brush or roller designed for the type of paint you’re using. Apply thin, even coats, allowing each coat to dry completely before applying the next. Work in the same direction with each stroke, avoiding overlapping strokes. For drips, ensure the paint isn’t too thick and control the amount of paint on your brush or roller. Slow, deliberate strokes will help to prevent dripping. Consider using a high-quality paint sprayer for a truly flawless finish, particularly on larger surfaces. The sprayer will help minimize brush strokes and ensure an even coat.
Proper Drying Time and Ventilation
Adequate drying time and proper ventilation are critical for preventing problems. Insufficient drying time can lead to a sticky or tacky surface, making it difficult to apply subsequent coats and potentially leading to cracking or peeling. Poor ventilation can trap moisture, slowing down drying time and possibly causing bubbling or uneven finish. Always refer to the paint manufacturer’s instructions for recommended drying times and ensure adequate ventilation during and after painting. If issues arise from improper drying, such as bubbling or wrinkling, carefully sand the affected areas and reapply the paint, ensuring proper drying conditions this time. In extreme cases, you might need to completely remove the affected paint and start again. A well-ventilated area, ideally with a fan, is highly recommended.
