Painting Stucco & Repairing Cracks With Caulking & Elastomeric Paint

What happens here

For larger cracks, apply Sherwin Williams 950A caulk directly into the crack using a caulk gun. Wear rubber gloves for protection and to assist in the next step. After applying the caulk, dab and press it into the stucco surface with a gloved hand. This technique helps push the caulk deep into the crack and creates a textured finish that blends with the existing stucco, making the repair less noticeable than a smooth, flat caulk line. For superior flexibility and adhesion in stucco, 'Big Stretch' caulk is recommended as an alternative.

Goal: Fill and blend larger cracks into the stucco texture.

we're going to show you that process right now. I got a few cracks right here. This is a pretty large crack right here. And it's we're spraying with an elasame coating that's designed to cover hairline cracks. And this crack is way too big. So you're going to see some of the cocking up here. It's not ideal to the Stuckco cuz you'll typically always see where you cocked it just as bad as the crack itself, but the customer is more concerned about the crack. So these ones that the elastimeone is designed not to cover and span the gap, we're actually coughing these. And I'm just taking rubber gloves and using a cocking from Sher Williams 950A and cocking these cracks. And you're just trying to put just enough cocking on there just to fill that crack in. And I'm just going along pumping it inside the crack. And once I get it filled, then I'm just dobbing it with my hands, trying to blend it in. And that's an important step, just pressing it with your hands and not actually just making a smooth line. So, you kind of want to do it to push it into the stucco and blend it into the stucco. Here's another pretty large crack right here. So, I'm getting the caulking down. I'm just going to take and do it. Trying to make the the stuckco kind of roughs or the caulking kind of rough so it blends into the stucco.
