How do you seal a floor after sanding?

The process of sealing a floor after sanding involves removing dust particles and debris left behind by the sanding process, then applying a sealant to the floorboards. Different steps need to be followed depending on the type of flooring and what kind of sealant is being used.

For wooden flooring, the first step is to make sure the entire surface is clean and dust-free. A vacuum cleaner or dust mop can be used to clean everything. Once the dust is cleared, the sealant should be applied in thin coats. It is important to use even strokes, and it's best to start at the room's outer edges and work inward. Between coats, it is essential to allow the sealant to dry completely, usually for at least two hours. This process should be repeated until the desired level of protection is achieved.

For tile or concrete flooring, the sanding process usually doesn't require removing any dust, as the grout lines will keep the dust particles from reaching the sealant. After the process is done, the sealant application is much the same as with wooden floors. The sealant should be applied in thin coats, using even strokes and starting at the room's perimeter. Again, it is important to let the finish dry completely between coats, and some sealants may require multiple coats to achieve the desired level of protection.
