The number of times a timber floor can be re-sanded and polished depends on the thickness of the top wear layer of the wood. In general, solid hardwood floors have a thicker wear layer compared to engineered hardwood floors. For solid hardwood, you can typically re-sand and polish it 4 to 7 times during its lifespan. However, this number can vary based on the initial thickness of the wear layer, the expertise of the professionals performing the sanding, and the care taken during the process.
For engineered hardwood floors, the number of times you can re-sand and polish is generally more limited. The thickness of the veneer layer on engineered wood is thinner compared to solid hardwood, so the number of sanding sessions is often limited to 1 to 3 times. It's crucial to consult with flooring professionals to determine the specific characteristics of your flooring and understand how many times it can be successfully re-sanded without compromising its integrity. Regular maintenance and proper care can also impact the overall lifespan and the number of times a timber floor can be refinished.
