Sanding Wood - Flat Surfaces and Boards
How to Sand Wood - Plane Wooden Surfaces and Boards
When using wood in construction and decoration projects, one aspect is impossible to overlook, regardless of what type of wood you are using. We're talking about sanding. A piece of wooden furniture, such as a cupboard, needs to look its best, and this is where a high quality sanding process is crucial.
A good sanding result is especially important for products where wood grain remains visible in the finished product, but also if you are planning on applying paint or lacquer. The better the preparation, the better the result.
Mirka offers abrasives and tools to help you achieve a flawless end result, together with our dust-free solutions which make it possible for you to sand with virtually no dust.
Easy Steps to Sanding Flat Wooden Surfaces and Boards
1. Tools
The first step to sanding wooden surfaces is choosing the right tool for the job. Mirka offers a wide range of electric sanders: the orbital Mirka® DEOS sanders, and random orbital sanders in the Mirka® DEROS product range.
No matter which one you prefer, both sander ranges are similarly well-engineered, featuring a low and lightweight ergonomic design to ensure you can sand for long periods without fatigue, with high manoeuvrability and precision.
2. Abrasives
The choice of abrasive to use for the job depends on what type of wood you are sanding.
Mirka offers excellent all-round alternatives whether working with softer woods such as pine or a hard wood such as oak. Our recommendations are Iridium®, for when you want a premium paper abrasive that is both fast and efficient, or the Abranet® family of abrasives, if you are looking for high material removal performance together with cost-effective sanding.
3. Dust Extraction
Dust is a natural side product of sanding, but it is a negative one. Not only does dust make your workspace look dirty, it can also have a hazardous effect on your health: the most dangerous dust is airborne, as by the time it settles on the working surface it has been in the air for long, for you to breathe. Long term exposure to dust from certain hard woods can be especially harmful.
Mirka's dust extractors can help you minimize the amount of airborne dust created from sanding. Combining the extractor with our tools and abrasives you will get a dust-free solution that is not only good for your health, it also reduces time spent on cleaning up after you have finished your work.

Top Surface Preparation Tools and Their Uses
Uneven surfaces, leftover paint, and construction dust can ruin the quality of a finish. Many projects fail or take longer because surfaces are not prepared properly before painting or coating. This often leads to peeling paint, uneven textures, and extra time spent on repairs.
Using the right surface preparation tools solves these issues by creating smooth, clean surfaces ready for finishing. These tools save time, improve efficiency, and deliver long-lasting results in construction and renovation projects.
In this article, we look at top surface preparation tools and their uses to help you choose the right ones for your next project.
Why Surface Preparation Matters in Construction and Renovation
Proper surface preparation ensures that coatings, paints, and finishes adhere correctly. Skipping or rushing this step can lead to peeling, uneven textures, or premature failures, increasing rework costs.
A smooth, clean surface creates a professional-quality finish. Sanding walls, ceilings, and woodwork removes imperfections, old coatings, and debris that can affect the final look. Mirka's research shows that increasing sanding time by 20% can reduce final finishing time by 30%, which means investing slightly more effort in surface preparation can significantly reduce finishing time and improve overall productivity.
Surface preparation also improves efficiency during installation and finishing. When surfaces are ready, paint and coating applications go faster, require fewer touchups, and deliver consistent results. According to Mirka's research, dust-free sanding can eliminate up to 2–3 days of cleaning compared to traditional sanding methods, saving both time and labor costs on-site while improving job site safety.
In both construction and renovation, investing time in proper surface preparation saves labor, reduces material waste, and produces better long-term results for clients.

Safety and Best Practices for Surface Preparation
- Wear Proper Protective Equipment: Use safety glasses, a dust mask or respirator, hearing protection, and gloves during sanding tasks. This protects against airborne particles, noise exposure, and accidental contact with moving parts.
- Use Dust-Free Systems: Combine dust extractors with net abrasives like Abranet® and sanders such as the Mirka® LEROS, DEROS, and DEOS. This reduces harmful dust in the air, keeps the worksite cleaner, and helps avoid health risks associated with long-term dust exposure.
- Choose the Right Tool for the Space: Use the Mirka® LEROS for large wall and ceiling areas and the LEROS-S for confined spaces. Select DEOS for corners and edges, and DEROS for versatile flat surface work. Matching the tool to the task improves efficiency and reduces physical strain.
- Check and Maintain Tools Regularly: Inspect sanding pads, abrasive discs, and dust extractor filters before each use. Properly maintained equipment improves performance, reduces downtime, and extends tool life.
- Work in Comfortable Positions: Use ergonomic tools like the Mirka® LEROS with its 180° flexible head or lightweight DEOS for extended work sessions. Correct working posture helps reduce fatigue and lowers the risk of injury during long surface preparation tasks.
