Different Wood Floor Finishes Explained
There are a few considerations when deciding whether to use a surface (lacquer) or oil/wax finish for your floor. The application, appearance and maintenance of the finish will all vary depending on your choice.
Surface (Lacquer) Finishes
These are synthetic resins (urethanes / polyurethanes) that resist water well and require little maintenance. As the name suggests, a surface finish does not really penetrate the wood; instead it consists of a protective layer or seal on the surface of the floor. A surface finish can consist of up to five different applications or layers of the lacquer. There are four main types:
These are clear once dry, and will usually remain that way as they age rather than yellowing. Because they have a mild smell when applied and will dry in a few hours, good ventilation is less important for their use. They are reasonably long-lasting.
These not only take longer to dry (around eight hours usually) but will give off more fumes, so ventilation is more important. They are amber-coloured and will affect the colour of the wood. They are generally longer lasting than water based finishes.
These vary in colour from clear to pale yellow. They are quick drying (two/three hours typically) but will give off strong fumes, so proper ventilation is essential. They are very long lasting.
These are similar in all regards to acid cured finishes, but have two advantages: they will dry even in humid conditions and will resist moisture better than other types of lacquer finishes.
Oil Wax Finishes
These soak into the wood to protect the interior of each plank; once dry; the top layer of the finish is then buffed to a gentle shine. Drying times vary according to the wood species, the type of finish used, the number of applications and the conditions on site. They generally give off less fumes when drying.
Maintaining an Oil Wax Finish
As long as the floor is clean and does not need another application of the oil wax, then buffing should restore its shine. Rather than complete replacement every five to ten years, refinishing / polishing is needed once (perhaps twice) a year as the surface finish gradually wears away and gets dirty. When cleaning, always use a solvent (not water-based) cleaner specifically recommended for oil wax finishes, wipe clean and then allow at least twenty minutes drying time. Then apply another layer of the oil wax and allow that to dry before buffing.
Pros and Cons
Surface (Lacquer) Finishes

Although some scuffs and scratches can be fixed, the coating will gradually lose its shine (even when clean) and gather more wear and tear. Eventually it will need to be completely removed with a floor sander and a new coating applied.

Oil / Wax Finishes

However, because the finish soaks into the wood as needed, individual areas can be repaired or re-treated, so the floor’s finish as a whole will generally last longer and the floor will also age beautifully and take on a new character throughout its lifetime.
