Wooden floor sanding is done with specialised sanding machines. The floor is then finished with the desired protective coating; oil or polyurethane etc.
Wood floor sanding is done with large belt or drum sanding equipment. The majority of material is removed by these sanders. The areas where the large sanders cannot reach, such as edges, corners, and stairs, are sanded by an edger/hand tool. A finishing machine is then used for the final floor sanding.
Preparation is the first stage of the floor sanding process. All nails which protrude above the boards are punched down. Nails can severely damage the sanding machines which are being used. Staples or tacs used to fasten previous coverings (if any) have to be removed to reduce the possibility of damage. Adhesives which have been used to secure floor coverings will have to be removed. These adhesives can clog papers and running gear of the machines used, and some can even make sanding impossible. Other machinery like grinders may need to be used.
Sanding begins after the floor is properly prepared. The first cut is done with coarse-grit papers (Typically 16 to 40 grit) to remove old coatings and to make the floor flat. The differences in height between the boards are removed. The areas which cannot be reached by the large sanders are sanded by an edger. If filling of holes or boards is desired this is the stage where this is usually done. The process is then repeated for the second cut using a finer sand paper, typically 60-120 grit. A disking finishing machine is then used to create the final finish.
The sanded floor can be coated with polyurethane, oils, stain or other sealants to give the end finished result and to protect the floor.
Usual process is the use of polyurethane to bring out the best in your floor sanding. 3-4 coats are required to give great results with disking and cleaning between each stage. Different levels of sheen are available. Low sheen to full gloss.
Maintenance coats will be required around 2-5 years later. These are crucial to the long life of the floor, known in the industry as a ‘reglaze’, cost is minimal. If proper maintenance is not kept then these coatings will be compromised, this will lead to a re-sand of the entire floor. There are only 6-8 sands in a floor before it needs to be replaced.
General cleaning is best performed by a micro fibre static mop for day to day cleaning. This keeps the dust levels down which prevent premature wear and tear on the top coat. Weekly or monthly cleaning is best done by washing the floor. Please check up on what is best to clean your floors before cleaning with something you have found from the supermarket.
