What Is a Sub-Floor Adhesive?
A sub-floor adhesive is used to repair substrates such as walls and ceilings and to adhere finishing materials.
This adhesive typically consists of acrylic resin, cement, and various additives, and is applied in a water-dissolved form. Upon drying, it forms an adhesive film that fills in fine irregularities and smooths the substrate surface, thereby enhancing the adhesion of finishing materials.
It finds application in a range of scenarios, including substrate treatment for walls and ceilings, joint treatment for gypsum boards, repair of tile substrates, substrate treatment for wood surfaces, and the repair of old painted surfaces. The adhesive is noted for its versatile adhesion to different substrates, its repair capabilities for smoothing surfaces and filling in irregularities, its ease of application, quick drying properties for rapid project completion, and its compatibility with various finishing materials.
