What happens here

Mix S-type mortar (a high-strength blend suitable for veneer) with water in a bucket using a paddle mixer until it achieves a peanut butter-like consistency. Apply a 'scratch coat' of this mortar to the metal lath, ensuring all honeycomb openings are completely filled and the metal mesh is no longer visible. Allow this layer to firm up for approximately one hour. Then, apply a 'score coat' using a 1/2-inch (1.27 cm) notched trowel to create horizontal grooves in the mortar. These grooves provide additional grip for the stone veneer, preventing it from sliding down. If the mesh moves during application, re-secure it with a nail or screw and continue.

Goal: Create a strong and textured mortar base for stone veneer.

all right so we got our medal laugh on it's time to fill this area this is a blend of motor mix it's the s-type that's very important so when you guys find we're gonna make a bucket with water using a paddle mixer to the consistency of peanut butter easy enough to follow now then we're gonna do two different types of coats the first one's called a scratch coat we're gonna take our trowel and we're gonna fill this entire honeycomb so we can see that metal mesh and let it drive firmly for an hour I said any point any of the mesh moves stop secure it with another nail or a screw and then continue it on we're gonna let it sit firm for about an hour once that's done we're gonna do the score coat and what we're gonna do there is grant take more of the mixture and use the half-inch straus to make horizontal lines again the horizontal parts are gonna be allowing for the stone to actually be gripped as opposed to slide down so get to work [Music] well if you guys have been following me for any time at all you know that I
