Ultimate Guide: Answering the 10 Most Common Questions about Floor Sanding and Varnishing

Floor sanding and varnishing are essential steps in maintaining the beauty and durability of your wooden floors. As a homeowner, you may have questions about the process, the tools used, the types of finishes available, and how to choose the right professional for the job. In this comprehensive blog post, we will address ten commonly asked questions about floor sanding and varnishing, providing you with the knowledge needed to make informed decisions and ensure your floors look their best for years to come.

Question 1: What is floor sanding, and why is it necessary?

Answer: Floor sanding is the process of removing the top layer of a wooden floor to eliminate imperfections, scratches, and dents that have developed over time. This is done using specialised sanding machines, which grind down the surface of the wood to create a smooth, even surface. Sanding is necessary to prepare the floor for varnishing and to restore the natural beauty of the wood.

Question 2: What types of floors can be sanded and varnished?

Answer: While most types of wooden floors can be sanded and varnished, some floors are more suitable for this process than others. Hardwood floors, such as oak, maple, and walnut, are the most common candidates for sanding and varnishing due to their durability and long-lasting nature. However, engineered wood floors can also be sanded and varnished, although their sanding capabilities are limited due to the thinner veneer layer.

Question 3: How often should I sand and varnish my wooden floors?

Answer: The frequency of floor sanding and varnishing depends on the type of wood, the amount of foot traffic, and the quality of the finish. As a general rule, hardwood floors should be sanded and refinished every 7–10 years, while engineered wood floors may require sanding and varnishing every 10–15 years. However, you should consult a flooring professional to assess your specific situation and determine the appropriate maintenance schedule.

Question 4: Can I sand and varnish my floors myself?

Answer: While it is possible to sand and varnish your floors yourself, hiring a professional is strongly recommended. Floor sanding requires specialised equipment and skill to achieve an even, smooth surface. Additionally, improper sanding can cause permanent damage to your floors, leading to costly repairs or replacements. Professional floor sanders have the experience and equipment needed to ensure a high-quality finish.

Question 5: What types of sanders are used for floor sanding?

Drum sanders are powerful machines used for removing large amounts of material quickly, making them suitable for initial sanding. Orbital sanders are less aggressive and are used for finer sanding and finishing. Edge sanders are smaller, handheld machines used for sanding the edges and corners of a room where larger sanders cannot reach.

Question 6: What are the different types of varnishes available?

Answer: There are three main types of varnishes used for wooden floors: water-based, oil-based, and solvent-based. Water-based varnishes are environmentally friendly, low-odour, and quick-drying. Oil-based varnishes are more durable and provide a richer, more natural-looking finish. Solvent-based varnishes, also known as lacquers, are the most durable and provide excellent resistance to wear and tear. The type of varnish you choose depends on your personal preference, your budget, and the specific needs of your floor.
