plastering the supporting wall
 
Hi, need some advice on this please. As I understand its a 2 coat process ( or us it 3 coats?). First layer needs to be scratched so second/final coat adheres to it. Can I leave a long gap in time between coats? I assume thats ok?
First scratch coat should be thicker if the two.
What do I scratch with?
Am I making any obvious mistakes here?
Any advice welcome

Thanks

Richard

Here is a article that helped me gain some understanding of the stucco process.

Hope this helps. I'm no expert but I'll try to help you if I can.

Scratch, brown, finish. Use more line with each layer.

We just used Quikrete Quikwall Surface Bonding Cement and acrylic fortifier, then added stucco color and covered with one coat. Just another option.

Richard, we just took a narrow board (about your forearm's length) and put screws through it every inch or so. The screws went through about 1/2 - 1 cm, as long as they are even it doesn't matter how far they go through. Then you just drag the board over the first stucco coat and the screw tips scratch the surface nicely. The outer, 2nd, colored layer will dry fairly quickly if you don't mist/lightly wet the first layer - so you need to have everything ready, make more stucco than you need, work quickly, and relax...nobody will notice if you make a mistake or that the stucco's not "perfect" when they have a freshly baked pizza in front of them! ;)
