plaster, it’s everywhere you want to be
Hello everyone, in this video I show another way of repairing or fixing a large structural crack with polyurethane caulking in a stucco wall.
The crack shown here is structural, meaning it will always move.
I feel it’s best to use a flexible material under the circumstances. There are about 20 different ways to repair the crack properly.
The best way tearing off all the stucco and re-doing the complete wall.
But I get beat up if I suggest this to most customers.
Again, I will say there are many ways to fix a structural crack.
I am implying to just fill it with stucco is the easiest, but far from the best as when a structural crack moves again and it will, as it’s structural in the first place, the stucco will simply crack with it.
(for me structural means when it rains plus a bunch more reason, the area or wall will lift then when dryer conditions occur, settle, thus structural)
If a polyurethane caulking if used first and the texture can’t be matched with that caulking a person cam apply a stucco with sand to match a texture using stucco on top of all this caulking,
Is a bonding agent necessary?
If the caulking is allowed to set and or dry, yes a bonding agent would now be necessary to adhere the new stucco to this area,
if added while the caulking is still curing is a bit tricky as can it affect the integrity of the caulking?
Good question, yes.
But for a temporary fix, say 15 years, it is an intelligent alternative for keeping the rain water out to the alternative of tearing the wall apart and trying to locate why the walls is moving and or separating.
