How to Mask Windows & Doors for Exterior Spraying | Pro Tips for Windy Conditions

What happens here

For the bottom edge of the large window, just like with small windows, tuck the excess film underneath the frame. Then, use 1.5-inch tape to secure this tucked-in section, creating a firm seal. For the corners and any small gaps where the masker blade might have caused a tear, apply small pieces of tape to ensure full protection from overspray. Always double-check that all edges are tight and there are no leaks before proceeding with painting.

Goal: Completely seal and protect the large window from overspray.

Pull this down, pull it tight, like that. Things tight, I'm going to come over here, work with this side before it lifts it up. I'm going to grab this, tack it down. It's going to hold it, it's like that. The wind's going that direction. So I'm going to pull this down, take a piece of tape, and tack it down right here. Pull it down tight. We'll tack it all the way down the bottom. Wind's not too bad today. You see, I'll take this, just grab it, pull it, pull it tight. This line straight, now being a sliding glass door. The rest of that, you know, we've got spraying down here, spraying top. You know, if you're concerned about overspray on there, I can just run paper right here, hand roll the bottom, or I can just run another row of plastic and drop it down. I can run, if the wind is blowing this direction, I can run plastic this direction, do this. Now I can just take, it's like this, right there. Tack that right there. Just tuck this under right here. Now, if the masking isn't coming up, I'm trying to push it down to touch it on there. If you have to, just run another row. You get it to touch that plastic. Run this over here. We don't want overspray going down inside there. That's all protected. I'm going to come across the bottom, a hard time seeing the bottom, the cocking's white, the window's white. My eyesight's not good, getting old. One more row. So if I'd mass this 100%, then I can actually just spray that bottom and not actually have to brush and roll it. So it all depends on, you know, your preference, you know, what you think is faster. It's all looks good. It's like we've got a couple holes right there.
