What happens here

Before applying any final finish, thoroughly inspect your shakes for any signs of blistering, especially in the seams or on gable ends. Gable ends are particularly susceptible to blistering because they are often hotter due to attic heat and lack the insulation of side walls. Blistering creates pockets where the paint can lift and peel. To effectively prepare the surface, use a triple-thick, high-resin primer. This type of primer is designed to 'glue' down the blisters, preventing them from reappearing after painting. Apply the primer with a brush to ensure that it penetrates deeply into the slats and covers all affected areas. It's critical to complete this priming step *before* painting, as attempting to fix blisters after the final paint has been applied will yield poor results.

Goal: Repair and seal blisters on shakes to ensure a smooth, durable finish.

It's very common that that there's blisters in there. You want to fill those blisters in. You want to glue those things together before you paint them. You don't want to do any anything like that after, you know, the the painting process. So, it's it's pretty typical. I'd go up there and you'll see, you know, triple thick primer all over those slats. I don't know why for some reason those blister, you know, more than say like the siding. It could be like on those gable ends, the gables get a lot hotter cuz it's in the attict and and it's not, you know, insulated like it is on the the side walls. But triple thick primer is a super high resin primer that will glue all that blistering together. Then I'll spray it. Another tip, when I
