Repairing and Prepping Stucco for Airless Spraying

Watch on YouTube

What happens here

The presenter explains that after scraping and patching, he needs to prime the bare stucco areas, especially where he scraped down to the original surface. He uses a Sherwin Williams Loxon Concrete & Masonry Primer Sealer, applying it with a 4-inch roller with a 3/8-inch nap. He rolls slowly and with heavy pressure to push the primer into the texture, avoiding splatter. This priming step ensures better adhesion and a more uniform appearance for the final topcoat, and it also helps seal the porous concrete/stucco. He moves the ladder around to reach all the bare spots that need priming. He highlights that in his climate (Idaho), stucco doesn't weather well due to freeze-thaw cycles, and water often gets behind it, causing flaking. Priming helps seal these vulnerable spots.

Goal: Apply a concrete and masonry primer to all repaired and bare stucco surfaces.

no tent so i'm just up here got some bare areas and from down below you can't see as well once you get up here you can see they're worn down or bare right to the the finish stucco finish here and so i'm just being very careful i don't want to roll too fast too quickly or else it's just going to splatter paint and being up high like this you know you could splatter paint for your quite a distance i've got underneath me it's just dirt so i'm not worried about that when i get over here there's a sidewalk and stuff i want to be careful not to get anything on the sidewalk i would be laying down cardboard on the sidewalk to protect that so just nice slow easy roll with heavy pressure pushing this into those bare areas it's just going to make the once again the top coat stick better bond better to these kind of areas they're a little bit troubled a little bit crumbling help seal them up anywhere where i use stucco patch it's also a good air good idea to prime those the stucco patch also because it'll be extremely porous not primed so it's good to just roll over some locks on on those areas also all these that's caulking too i'm just rolling on and around this caulking too to seal all around the edges of this caulking too that will help my caulking last longer also if i see any cracks i can back roll over my hairline cracks right now also then i wouldn't have to do them when i do my top coat either just put a nice good heavy coat you don't want to you run your nap dry and dry nappy you want to get a good thick coat of this primer on there once again looking for anything bare any caulking i put on or any hairline cracks for stucco in idaho this is actually in pretty good shape i stucco is does not weather too well in idaho it's um because of the extreme winters freezing thawing um water likes to get in sight and stucco freezes and thaws starts to cause it to flake and crack off
