hydrating or wetting walls prior to color coat, stucco wall texture techniques
Hello everyone, today Jason and I are explaining the importance of hydrating walls prior to applying a color coat cementitious finish.
FYI, I like to hydrate a base coat at least 3 to 5 times within that 2 to 3 week cure time.
The idea is to fill it so full of water that it EXPANDS, then when it shrinks or drys it will naturally hairline .
If you hydrate your new base coat at least 3 times this will happen, 5 times will make sure it does.
Why is this so important?
If you don’t hydrate (or hose down with water) the new stucco base coat, before you apply a finish coat the water needed to apply the color finish coat will hydrate it or expand it (base coat) and when the color is dry, this new color finish will also hairline naturally with the base coat stucco.
Or say a person that never hydrates new walls then applies a color finish, then 1 week and or to 5 months goes by and old mother nature rains on these same walls for a week straight, what will happen?
The new walls with stucco will finally expand (with the rain water) then dry, and more than likely hairline as this process is natural with Portland based stucco products, thus, a pretty new color finish also hairlines with the stucco base coat.
I hear this this comment often, “these guys did a great job, but now it rained and it looks awful with cracks, why”
I usually say they did not hydrate properly. BTW, this happens to the best of us sometimes.
Lastly in this video, I am showing the steps I take prior to an application of applying a color finish, we were not able to show the application of this finish as it was getting dark and we had to hustle.
Therefor Jason could not film anymore as I need him to spread fast so I could float these walls.
It’s not possible for him to spread mud and film at the same time, unfortunately.
