#1.KILZ Adhesion High-Bonding Primer
We think the KILZ Adhesion is the best bonding primer for those who want maximum adhesion to really tough to work with bonding surfaces. So think glossy and slippery surfaces. It just simply works better than most of the standard primers out there for these types of surfaces. Also, it is pretty good value for the money.

#1.KILZ Adhesion High-Bonding Primer
When it comes to the best bonding primer, we have to give it to the KILZ Adhesion High Bonding Primer. This stuff works very well in securely bonding to all sorts of surfaces both indoors and outdoors.This primer is actually specifically designed to adhere to tough to paint over surfaces, so it shines in bonding securely to hard glossy surfaces, where traditional oil or water primers just don’t cut it.
So some other examples of these tough surfaces are fiberglass, chalky paints, tile, vinyl, PVC, glazed brick, certain metals, and Formica. If you are working with any of these surfaces, the KILZ Adhesion works.Also, we find coverage to be pretty good as well. One gallon of this stuff can cover about 300 square feet. It also dries to the touch in about 30 minutes and can be recoated in one hour.
#2.Rust-Oleum Bondz Maximum Adhesion Primer
Another great option when it comes to the best bonding primer is the Rust-Oleum Bondz Maximum Adhesion Primer. It is a low VOC water based primer that bonds to surfaces that are normally bad for coatings.Compared to the KILZ Adhesion, the Rust-Oleum Bondz works about as well but we prefer the KILZ just because we think it is an easier primer to work with.
The Rust-Oleum Bondz has great flow and leveling properties making it easier to apply. Also it bonds to hard and dense interior to exterior surfaces like fiberglass, laminate, galvanized steel, brick, and aluminum.Finally, we just want to note that it also does a very good job in forming a permanent bond with most topcoats, including solvent based paints and 2-part epoxies.
#3.INSL-X STIX Bonding Primer
Next, we have the INSL-X Bonding Primer, which is the best bonding primer for painting supplies paint and stains. You can use this primer on pretty much any surface both interior and exterior.We would say its standout feature is that it really does have great adhesion to literally anything you can think of, from waxy plastic to slippery glass.
Additionally, we like the fact that it cures to temperatures of as low as 35 F. This is a lifesaver for some exterior surfaces and we can’t say the same with other primers.Also, we really like the it can be topcoated with pretty much anything and has excellent enamel holdout. It also creates extremely hard film.
#4.XIM 11051 Advanced Technology UMA Bonder
The XIM Advanced Technology UMA Bonder is a great bonding primer that also acts as a traditional primer and sealer. It is white in color and bonds to exterior and interior surfaces.We think it has a leg up on the competition in terms of overall durability. It does a great job in resisting wrinkling, blistering, or cracking due to moisture.
We also like how it cures well in low temperature and high humidity as well as how easy it is to clean with just soap and water.Finally, we like how it accept all types of topcoats and does a really good job in resisting blistering and peeling.
#5.Custom Building Products Bonding Primer
Finally, we have the Custom Building Products Bonding Primer, which is a ready to use single component primer that works on many different types of surfaces both indoors and out. Perhaps the standout feature is that it really does a good job in bonding to porous substrates, which other primers have a huge problem with.
And while it certainly works on non-porous surfaces, we think the Custom Building Products Bonding Primer works best on porous surfaces. It really gets into the cracks and pores and fills them up evenly. We also like the fact that no shotblasting or scarification is needed, which has proven to be quite convenient.
