When it comes to enhancing the beauty and durability of your wood floors, finishing primers play a pivotal role. Whether you're a DIY enthusiast or a professional contractor, understanding the ins and outs of finishing primers can significantly impact the outcome of your flooring project. A finishing primer is a coating applied to the wood surface before the final finish to improve the adhesion between the floor and varnish, and to increase the durability, preventing your floor from scratches, scuffs and other wear and tear.
