What happens here

This step examines painting new or previously painted composite siding, which often resembles wood but is a fiberboard material. While it can be painted multiple times, new composite siding is often porous. When painting such a surface, especially the first time, it is highly recommended to spray the paint first to get it on quickly and efficiently, then immediately back roll it. This action pushes the paint into the porous material, enhancing adhesion and penetration. Even when repainting aged composite siding with open blisters, back rolling primer into those areas before painting helps seal and adhere the paint, ensuring a longer-lasting finish.

Goal: Understand the necessity of back rolling for porous composite siding to ensure adhesion and penetration.

and I got the outside this building and what we got is a composite siding and we'll talk about that right now so I do have this composite siding on the outside of the house and it's been already painted multiple times but if it hasn't been painted it comes out it's not an actual wood material a lot of people see and in my videos they'll see this wood siding it looks like wood but it's not it's kind of a glorified cardboard it's a fiber board that's got glues and primers and it's pressed and so it looks like wood but it is very porous when it comes out it comes out pre-prime and the very first time that you paint that it's really really good idea and highly recommended to spray the paint you can roll it if you want but you can spray it to get it on and get your paint on a lot faster the painting process is gonna be a lot faster and you're just gonna make a lot more money if you ply it with a sprayer but it is really really good and highly recommended to back roll it there's no pin holes there's no blistering and stuff like that from an aged product but it is kind of fibrous and it is a little bit porous so back rolling is gonna push the paint in after you spray it's gonna push it in it's gonna enhance the adhesion and it's gonna enhance the penetration so you definitely want to back roll it now after it's been back rolled and painted and say five six years down the road when it needs to be painted again it's already been back rolled once it has a nice smooth you know coat of paint on there it's probably just faded because the paint is aged so I really don't have to go back in back roll at that point in time now there might be some Sun beatin sides that got some open blisters now in those open blisters if there's open blisters
