Sika makes specialty adhesives, sealants, primers, and activators for marine bonding and sealing work. Find the system pieces you need for a lasting bond. Building a Sika System Sika bonding and sealing jobs often use more than one product. Activators like Aktivator-100 and Aktivator-205 prep and clean the surface so the adhesive grips. Primers such as Primer-206 and Primer-209 then prepare specific substrates, from glass to painted surfaces, for a strong bond. Skipping these steps is the most common reason a sealant lets go early. Choosing by Job Match the product to the substrate and the load. Read the label for the surfaces it is rated for, the cure time, and whether a primer or activator is required first. Bottle...

Match the product to the substrate and the load. Read the label for the surfaces it is rated for, the cure time, and whether a primer or activator is required first. Bottle sizes range from 250ml to 1L for activators and primers, so you can buy a small bottle for a single project or a larger one for ongoing work. When in doubt, follow the Sika prep sequence for the best result.
Often yes. Sika activators clean and prep the surface and primers prepare specific substrates. Check the adhesive label, since skipping these steps is a common cause of early failure.
They are surface activators for different applications. Always confirm the product against the substrate and adhesive you are using on the label.
Many Sika primers and activators are offered in 250ml and 1L bottles, so you can match the quantity to the size of your project.
Sika offers marine grade bonding and sealing products, but you should verify the specific product is rated for your substrate and application on its label.
