Stucco Lath Application Tips Stucco Lath Application Tips
There is little difference to applying stucco to lath than there is to applying it to stone. The main points to watch out for are:
Fix Lath Securely
The lath must be securely fixed to the wall. Masonry nails are best for brick walls.
If the lath has large gaps it may be necessary to fill them to get a smooth and regular finish.
The lath must be well cleaned and dust free.
The lath must be coated with some form of bonding agent. Raw lath is likely to absorb too much moisture from the stucco mixture and cause cracking while it is drying.
When scratching the first layer to create the key for the next layer, be careful that you don’t expose too much lath and create areas with little adhesive tension.
Applying a stucco exterior to lath gives you an even better chance to correct any problems with the wall—by hiding them.
