Frequently asked

Is an adhesion promoter the same as a primer?

They do a similar job, but an adhesion promoter is usually a very thin treatment that improves bonding rather than a paint primer layer. Use the product your sealant's data sheet names.

How soon after applying it must the sealant go on?

The data sheet sets the drying time and the maximum interval before sealing. Sealing too early or too late can weaken the bond.
