What happens here

Using a Titan 440i airless sprayer, equipped with a Graco Rack X fine finish tip (or similar), apply a single, very light coat of bonding primer to the gutters. The video highlights using an oil-based alkyd resin primer like Ins-X Prime Lock (Interior or Exterior) because the house siding was also being primed with an oil-based primer to address wax bleed. A bonding primer is essential for metal surfaces like gutters, as approximately 10% of unprimed metal may crinkle and peel over time. Apply a thin, even coat to avoid drips or runs, ensuring proper adhesion for the topcoat. Allow the primer to dry for at least one hour (or according to manufacturer instructions, as this is a fast-drying oil primer) before proceeding to the next step. Ensure you wear appropriate personal protective equipment (PPE) such as a respirator and safety glasses during this process.

Goal: Ensure paint adhesion and prevent future peeling on gutters

What they say

roof. And our first step is going to be to actually spray these gutters with a primer, a bonding primer prior to spraying them. You always want to spray the metal surface with a bonding primer, especially gutters, cuz about 10% of them will actually crinkle and peel if you don't prime them. And so we're going to be priming them here shortly. And then about an hour later, once the primer's dry, it's a fast drying oil primer, we'll actually spray them with our top coat exterior satin super paint with Rack X310 fine finish tip. One really light coat of our bonding primer is all you need. Just one quick coat. You don't want it too heavy or it's going to run. So, this is what our really light coat of oilbased bonding primer. We're actually priming the house cuz it has wax bleed. We're priming it with an oil-based primer. So, we just go ahead and spray our gutters at the same time with the oilbased bonding primer. If we're not priming the exterior siding because of wax bleed, we actually just use a waterbased bonding primer. It makes the process a little bit easier and easier clean up. Here's a look at the primer sealer that we actually use on the exterior of the house for our gutters. It's a oilbased alk resin based primer for interior exterior use.
