Wood Floor Finishing and Sealing

After the wooden floor sanding and buffing process is complete, it is time to protect the flooring with the most appropriate seal. Some people might call this wood floor varnish, but in professional terms, the varnish is only one type of wood floor seal.

If you want to economize on your project, we advise you to opt for a lower spec rather than an inferior seal. A cheap seal (B&Q, Wickes, or Homebase) will result in greater expense due to the need for frequent re-sands.

Quality seals protect the finished wood, offering a stain and wear-resistant durable finish that should, with the correct maintenance, last years.

Floor Finishing and Sealing

The Longevity of Your Wood Floor Seal

The durability of your floor seal depends on proper care and the specific type of finish. Under normal domestic traffic conditions, you can expect the following approximate re-coating times:

  • A partial acrylic seal should last 3–5 years.
  • A high-traffic seal should last 5+ years.
  • A wood floor oiled with mineral oil may need touch-ups once a year or sooner.
  • A hard wax oil may require touch-ups every 4–5 years, if not sooner.

These timeframes can vary based on factors such as foot traffic and the type of footwear that comes into contact with the floor. To make your floors last longer, you might want to make your house a “no shoes” zone.

Tip: If you want to avoid having to sand your wooden floor again, re-coat it before the seal is completely gone.

Remember that the quality of the seal you put on your floor is a very important part of sanding. Never compromise on your floor sanding project by choosing a low-cost, inferior seal—it’s worth investing in a high-quality finish for lasting results.

Understanding the Differences Between Wax, Oil, and Lacquer for Wood Floors

At Sanding Wood Floors, we often prefer using natural oil and wax products on wood floors. However, the choice between oil, wax, and lacquer finishes ultimately depends on personal preference. It’s important to understand the differences between these finishes to make an informed decision for your flooring needs.

Most wood floors in the UK have a lacquer finish, which provides a glossy, satin-like appearance. In contrast, oils and waxes give a more subdued shine, resulting in a subtler effect. Keep in mind that floors treated with oils and waxes require regular maintenance, while lacquer finishes only need routine cleaning.

One advantage of oil and wax treatments is that they allow for easier repairs compared to lacquer coatings. This can be especially beneficial for homeowners who expect their floors to experience wear and tear.
