Common sense Reasons why new stucco color coats crack.
Vibrations or movement is key cause of cracks in a color coat stucco.
Hi guys and gals, in this video I am explaining just a few reasons why stucco cracks.
I have first hand knowledge as I have been in this trade for over 30 years, within this time I have applied stucco to homes that have been on covers of magazines and even one that was so custom it appeared in a movie, which means I have time in.
A plastering contractors responsibility is the installations of metal lath, applications of scratch and brown coat and so on.
We as plastering contractors arrive at a newly built home don’t have any say in plywood and stud installations let alone movement, warping or expansion of plywood or OSB sheathing.
Engineering of foundations is also a huge factor.
Movement is key cause of cracks in a cementitious color coat, decks, sheetrock, tile or comp roofs, floors, headers weather for structural or cosmetic reasons SHOULD BE INSTALLED PRIOR to the stucco color finish coat.
In this video hammering was the key to the hairline cracking that occurred as the first month there were no cracks.
By the way us plastering contractor wait the standard 2 to 3 weeks for the base coat to cure as all base coat hairline, this is normal.
Bottom line is all contractors and homeowner should wait until you are completely done with your home requirements which includes even landscaping with a tractor before having a cementitious color coat applied.
