Yes, you can lay laminate flooring over floorboards, but there are some important considerations to keep in mind before doing so.
Firstly, the floorboards must be structurally sound and level. Any loose or damaged boards should be replaced, and the surface should be sanded down if necessary to ensure a flat and even surface.
Secondly, you should consider whether there is sufficient space to accommodate the added height of the laminate flooring. Laminate flooring usually ranges from 8-12mm in thickness, so you will need to ensure that doors and skirting boards can still be opened and closed without obstruction.
Thirdly, it is important to use an appropriate underlay to provide a level surface for the laminate flooring to sit on. This will also help to reduce noise and provide insulation.
Finally, it is recommended to leave a small gap around the edges of the room to allow for expansion and contraction of the laminate flooring. This can be covered with skirting boards or a suitable trim.
Overall, laying laminate flooring over floorboards can be a great way to update and modernize your space, as long as you take the necessary precautions and ensure that the underlying surface is suitable.
