Frequently asked questions
Do I need underlay under laminate?
Yes, unless the planks have it pre-attached. Underlay evens out the subfloor, cuts noise and adds a moisture barrier over concrete.
Which direction should planks run?
Usually parallel to the longest wall or toward the main light source, which hides the joints best.
