What happens here

After the initial power wash, use a 3M All-Purpose Medium Sanding Sponge to sand the teal-green window frames. This step is crucial for scuffing the existing paint surface, creating a texture that allows the new primer to adhere properly.

Goal: Create a prepared surface for primer application.

What they say

Hide

Jake here is going to be power washing. The sanding is going to start off with a allpurpose 3M sanding sponge, a medium sanding sponge, and it's just a square sanding sponge. Makes sanding fast and easy on these windows. Here's a set of the windows, the green windows that we've actually gone and sanded. We first power washed them, got them really clean, and then we used medium 3M sanding sponges, and then once we've sanded them, we power washed them again with a power washer to get them really clean again.
