Polyurethane Glue is widely used in several applications such as construction, furniture, craft work, and flooring. It is usable on several surfaces including metal, wood, ceramics, rubber, and plastics. Polyurethane glue is very durable and long lasting, which makes it the preferred choice for indoor and outdoor applications. With the eight precautions described here, you can use polyurethane glue safely and gain the best results.

Wear Gloves: Polyurethane glue is fast acting and creates strong bonds in seconds. It cures and hardens in the presence of moisture, which it can get from your skin. To protect your skin, you must wear thick gloves and cover your entire body with long clothes when working with polyurethane glue. Even if the glue is removed, there are chances of skin irritation and rashes.

Prevent Inhalation: If inhaled, polyurethane glue can be an irritant to the nasal and respiratory tracts. Some individuals may also experience severe, allergic reactions to the glue. It is therefore important to wear some sort of face mask that minimizes inhalation of the product.

Work in a Ventilated Area: Always work in a ventilated area so that you are not exposed to concentrated vapors or gases emitted by the Solvent Based Adhesive . If you feel sick or have trouble breathing, go outdoors and get some fresh air till you feel better.
