Painting Stucco & Repairing Cracks With Caulking & Elastomeric Paint

What happens here

Wearing a respirator mask and gloves for safety, apply the SherLastic elastomeric paint using the airless sprayer. It is critical to move the spray gun extremely slowly, significantly slower than you would with regular paint. This deliberate, slow motion ensures that the paint is applied at a thickness of approximately 20 mils, which is necessary for the elastomeric coating to effectively build up on the stucco, fill hairline cracks, and span over the pre-caulked larger cracks. This thick application creates a flexible, rubbery seal that can expand and contract with the stucco, preventing new cracks from forming.

Goal: Apply a thick, flexible elastomeric coating to seal and hide cracks in stucco.

What they say

Hide

on it. Try to give you a close look of how thick it is on here. Spray it on extremely thick. You go a lot slower than you typically would with a regular airless spray and spraying regular paint. So you get a really good thick mill thickness. Stuff supposed to go on 20 ms thick. So, some of the key points while you're spraying this stuff, just make sure you go extremely slow. So, you can watch in the video, watch us spraying it. We're going probably twice as slow as we typically would on a regular house because you got to get that buildup on the stucco. So, the last America will get on there thick enough to the proper mill thickness and do its job of spanning the gaps of those hairline cracks and basically creating a nice flexible rubber seal that will span those uh cracks because they'll actually expand and contract over the winter time versus summertime. those cracks will get bigger and smaller and that elasame coating will flex and and not actually snap and break if applied properly over those cracks and you won't see them again. Here's a look at the side. We've already sprayed this side and I've inspected it for cracks and you can't see any of the cracks anymore on the side of the house whatsoever. They're covered 100%.
