Achieving a Seamless Finish: The Art of Sanding Interior Elements for Water-Based Coatings
In the world of interior spraying, the quest for a flawless finish on cabinets, furniture and interior elements, is an ongoing endeavour; this is more true when discussing kitchen cupboard doors. When working with Medium Density Fiberboard (MDF) and opting for water-based coatings, the paint certainly has a major part to play, however, one crucial step in achieving perfection is sanding. In this blog, we'll explore the importance of sanding in creating a smooth finish with Anker Stuy's Ankocryl Interior system and reducing fibre raise on MDF, with a specific focus on the new Mirka Ligno sanding pads.
Why use water-based coatings instead of solvent-based?
Water-based industrial interior joinery coatings possess a range of key properties that make them highly desirable in various industrial applications. One notable characteristic is their environmentally friendly composition, as these coatings use water as the primary solvent, resulting in lower levels of volatile organic compounds (VOCs) compared to traditional solvent-based alternatives. This not only promotes healthier indoor air quality but also aligns with sustainability goals. Despite their eco-conscious formulation, water-based coatings exhibit excellent performance, offering robust durability, resistance to wear, and a smooth, even finish on interior joinery surfaces like cabinets and furniture. The application process is user-friendly, with easy cleanup due to the absence of harsh solvents. Rapid drying times enhance productivity in industrial settings. Additionally, these coatings often showcase superior adhesion, ensuring a long-lasting and aesthetically pleasing appearance, making them a go-to choice for those seeking a balance between high-performance coatings and environmentally responsible practices in interior joinery applications.

Why use MDF?
Medium Density Fiberboard (MDF) is a popular choice for kitchen cupboard doors for several reasons. While the suitability of materials may vary based on specific preferences and needs, here are some reasons why MDF is often considered a good choice for kitchen cupboard doors:
Smooth Surface: MDF has a uniform and smooth surface, making it an excellent choice for painted or veneered finishes. Its consistency allows for a clean and polished appearance, which is desirable for kitchen cabinets.
- Affordability: MDF is generally more cost-effective than solid wood or other high-end materials. This makes it an attractive option for homeowners looking to achieve a sophisticated look on a budget.
- Versatility: MDF is a versatile material that can be easily cut, shaped, and moulded into various designs. This versatility allows for a wide range of styles and detailing, accommodating different design preferences.
- Stability: Unlike solid wood, MDF is less prone to warping or cracking due to changes in humidity and temperature. This stability is crucial in kitchen environments where conditions can fluctuate, especially if the kitchen is not climate-controlled.
- Paintability: MDF has a smooth, dense surface that takes paint exceptionally well. This makes it an ideal choice for kitchen cupboard doors that need to be painted in a specific colour or finish to match the overall kitchen design.
- Consistent Quality: MDF is manufactured using wood fibres, resin, and wax that are compressed together. This manufacturing process results in a consistent product with predictable properties. This consistency is valuable for achieving a uniform look across all cabinet doors.
- Eco-Friendly Options: Some MDF products are made with recycled wood fibres, and the manufacturing process can use wood from sustainably managed forests. This allows for eco-friendly options, contributing to responsible sourcing and environmental considerations.
- Resistance to Cracking and Splitting: MDF is less prone to cracking and splitting compared to solid wood. This durability is particularly important for doors that may experience frequent use, ensuring a longer lifespan for the kitchen cupboards.
- Weight: MDF is generally lighter than solid wood, making it easier to handle during installation. This can be advantageous for both professionals and DIY enthusiasts.
While MDF offers numerous advantages, it's essential to note that it also has some limitations, such as vulnerability to water damage. In areas where moisture is a concern, precautions should be taken to protect MDF from prolonged exposure to water. Additionally, the specific application and design goals should be considered when choosing materials for kitchen cupboard doors. Some types of MDF may do this job better than others, however whatever MDF you choose, rest assured that Ankocryl Interior helps to protect high-moisture areas better than most available paints.
The Role of Sanding in Smoothing Surfaces
Sanding is a critical step in the surface preparation process before applying any coating. When it comes to MDF and water-based coatings, the goal is to create a smooth and even canvas that enhances the final appearance. Sanding helps to eliminate imperfections, irregularities, and any raised fibres on the surface, ensuring that the coating adheres uniformly. Just try it out for yourself. Spray a 200um film on MDF and then sand with different grits, different durations and sanding pads from different companies. Spray on the topcoat and asses the finish for yourself.
