How many times can you sand and lacquer your wooden floor?
When you need to lacquer your wooden floor, it is important sanded the floor back to bare wood first. As a rule of thumb, assessing the need for a new coat of lacquer is based on how much wear and tear the floor is exposed to in your home, how well you clean and care for it and on which type of wood flooring you have. If you have a solid wood floor, you are able to be sand it more times than, for example, an enigineered wood floor.
Junckers' solid wood floors can be sanded to bare wood as follows:
- 14mm wooden floors - 5 times
- 15mm wooden floors - 6 times
- 20.5mm wooden floors - 8-10 times
- 22mm wooden floors - 8-10 times
If you are unsure about which floor type you have or whether your floor can withstand being sanded, we recommend contacting a flooring professional.
When should I sand and lacquer my wooden floor?
From a functional point of view, it will be time for a new lacquer treatment of your wooden floor, once the lacquer has worn through, down to the wood. A solid hardwood floor can be fully restored to good-as-new condition and correct maintenance will ensure it stays beautiful for many years to come.
You can also choose to sand and lacquer your wooden floor to choose a different surface treatment to achieve a completely different look. There are many finishing options to choose from, including Junckers' popular PreLak Colour primers and 2K Eco Protect Oils.
