What is ideal to stucco a wall of an old building (cement blocks and brick)?

Question

I am thinking of using metal lath however need to know what fastners do I use and how close I should put these fastners to hold the lath.

Do you use led or plastic anchors to put the screws in the wall?

Answer 1

To attach the metal wire lath use stainless steel screws spaced about every 10 to 12 inches.

Answer 2

Plastic is cheaper as many as you have to do and they will hold up well if you install them right.

How close depends on how thick you plan on putting the stucco on.

I've had luck with making my own pin's drill a 1/4 " hold and make a wire Bobbie pin with a 1/4" bind outwards on both ends. You have to squeeze them together to get them in the hold but they spring back locking in behind the brick. You have to custom make each one but with stucco in the hold they will not come out and the lath will stay up as long as the bricks and blocks do. Plus it is cheap.

Answer 3

Firstly why are you putting xpm on the walls?
There are forms of synthetic sheet materials that are now applied within the initial coat of render! If it is a specification for xpm, then you should be using stainless steel, I have seen galvanised xpm rust out in ten years! Fixings ss screws + ss washers, 300mm. apart in all directions
