Wooden floor sanding is a process that should be carried out professionally to ensure safe, top-quality results. Performance is a huge factor in sports hall flooring, which is why you might want to consider having your floor refurbished. Sports hall floors can become worn over years of constant use, which can affect the surface’s friction levels. This affects performance and safety, as it can result in slipping. Keep reading to find out about our top 5 rules for floor sanding.
You know what they say, preparation is key. That’s also true when it comes to wooden floor sanding! To ensure the process is carried and efficiently and effectively, some steps should be taken beforehand:
- Clear the room – this includes sporting equipment, seating, etc.
- Clean the floor – a deep clean of the floor will remove any dirt and debris that could interfere with the sanding machinery.
- Remove the baseboards – if your sports hall has baseboards, these should be carefully removed to avoid damaging them.
- Ensure good ventilation – lacquers will require a good level of ventilation to set, so this is something to consider.
- Check for damages – cracks in the wood could be problematic when it comes to sanding, so it’s important to check for any issues that could interfere with the sanding process.
- Make sure there is clear and safe access for engineers, as well as an accessible power source for equipment.
- Let your engineers know of any line markings/logos you’d like installed once the floor sanding is complete.
Your engineer will let you know of any specific accommodations they need you to make, but it’s a good idea to start with the ones above.
Always sand with the grain
It’s important to avoid sanding across the grain, as this will leave scratches and stop you from reaching that smooth floor look. Plus, it defeats the purpose of sanding the floor in the first place. You can identify the grain of the wood by looking for the lines – usually, it’s quite obvious, however, you might have to take a closer look. Sanding tools can be used along the axis of the grain, or as recommended by the manufacturer as this could be different for rotary tools.
Use the right equipment
Professional floor sanding equipment should be used for the best results. Sports hall floors tend to be quite large compared to a standard domestic room, so it can be a timely process without the right tools. Most modern floor sanders also use dust-extraction technology to minimise the dust particles in the air. This is especially beneficial in places like leisure centres and universities where members of the public will be passing by. Both coarse and fine sandpaper will be used on the floor (starting from coarse, moving to fine). This will, first, buff out any damages and surface coatings before smoothing out the surface with a finer grit. A professional floor sanding engineer will know which grit to use.
Clean between stages of sanding
It’s a good idea to clean between stages of wooden floor sanding to remove any fine dust from the surface of the wood. This will allow for a clear surface for the next stage of sanding or lacquer. A clean base will provide clean, smooth results! Avoid using a damp cloth to clean the surface of the wood when it isn’t protected by lacquer. This can cause the wood to swell and deform. Lint-free cloths or tack cloths are both great options for removing fine particles and preparing the surface for finishes and line markings.
Choose the best professional for the task
Sanding a floor can be a long, difficult process, especially if you’re looking for high-quality results. This is why it’s always best to hire a professional to complete it for you. At Courtship Flooring, we offer refurbishment services for all types of sports hall flooring. We sand back wooden floors using industrial strength machines, before closing the grain, applying primer, line markings and sports accredited lacquer.
