Step by step: How to sand your wooden floor

To renovate a wooden floor can seem complicated but then again be very rewarding. Follow our step-by-step instructions and discover the beauty that lies hidden in your old wooden floors.

Material check list:
Screwdriver, wooden wedges to remove skirting boards
Hammer
Vacuum cleaner
Stainless steel trowel for applying filler
Bona Edge
Bona FlexiDrum
Abrasives grit 40, 60 & 100
Paint scraper and/or sanding mouse
Preparations
Remove skirting boards carefully and check for protruding nails. Hammer them back in such a case. Make sure that there are no loose parquet blocks. These can be glued down. Afterwards, clean the floor using a broom or a vacuum cleaner.
 

Sanding

Normal Parquet Floors

Usually three stages of sanding are required.
• First, sand with coarse grit 40
• Continue with intermediate sanding using grit 60
• Finish with fine sanding using grit 100

Very Worn and Solid Floors

For floors which are uneven or if paint, pieces of carpet or glue are stuck to the surface, an additional stage is required. In this case start with grit 16 or 24 before proceeding as above.

1. Set up the sanding machine and tie the dust bag tightly so no dust can escape. Once started up, let the motor run until the bag is filled with air. This takes about 10 seconds.
2. Slowly move forwards and lower the sanding drum. Continue to move forward and when nearly reaching the wall, pull the handle upwards so that the drum is no longer touching the floor. Follow the same path backwards and carefully release the sanding drum while in motion.
3. Move the machine 15 cm to the right and create a new path, slightly overlapping with the previous path.
4. Use Bona Edge to reach all the way up to the wall. Sand using circular movements from left to right applying no downward pressure on the machine.
5. Repeat the sanding process once more now using grit 60 and then a final time with grit 100.
6. For corners, a paint scraper or a sanding mouse can be used.

Sanding Guidelines

For best results, follow the directions for each sanding stage. Start sanding diagonally to flatten the surface and then end with sanding in the direction of the wood. Make sure all old
treatment is removed.

Once sanded, carefully vacuum the surface and anywhere else dust may have gathered.

Periodic Maintenance For Beautiful Floors
After sanding, the floor needs protection to maintain its beauty. Bona can offer both durable varnishes and hardening oils for a natural appearance and long-lasting
results. Choose depending on personal preference and wear resistance requirements. We also offer an attractive range of paints in a variety of colours for a smooth and professional
end result. Bona works for a better environment, developing products with low emissions to improve indoor air quality.

Doing it Yourself has Never Been Easier

Sanding can be an enjoyable experience. Renting a professional sanding machine is straightforward; just ask your local retailer or where you purchased your Bona Step by Step products.
