Primers and Surface Prep Products

Prepare surfaces like a pro with primers from GracoRoberts. We offer a wide range of primers that are designed to improve adhesion and surface readiness for bonding, sealing and coating applications — helping you get the job done right. Whether you're working with plastics, metals, composites or rubbers, the right primer helps create a reliable foundation for the next step in the process. We carry primers from some of the leading brands in the industry, including LOCTITE®.

Improve Bond Strength

Primers are essential when working with hard-to-bond materials or when surface prep has to adhere to a tight set of specifications. The right primer promotes adhesion by preparing the substrate, reducing porosity and ensuring better contact with adhesives or coatings, resulting in stronger, longer lasting bonds. A popular option like LOCTITE® SF 770 Cyanoacrylate Primer is ideal for prepping plastics, including polyethylene or polypropylene. It makes it easier for cyanoacrylate adhesives to form a strong, lasting bond.

Trusted Brands and Formulas

Our primers are selected for quality, consistency and performance. They are designed to work in high-demand environments, such as aerospace, where temperature fluctuations, vibrations and other hazards are present. Whether you need a surface prepped for part assembly, structural repair, coating application or full-scale production, GracoRoberts offers primers that help improve results while saving time and reducing the risk of reworks. These primers also ensure strong, reliable adhesion across a wide range of substrates.
