Professional Caulking for Dummies or Caulking 101

Professional Caulking for Dummies or Caulking 101

Hello ambitious guys and gals, who wish to learn more about caulkings used by us professional stucco and plastering contractors, the caulkings I am mainly showing in this video are below
Number 1. Sikaflex 1A is a polyurethane caulking it’s the one I prefer when were lathing, it is a sealant and adhesive, I not only use it but recommend it highly as it has never let me down.
Being a licensed contractor I am responsible for any failures or water penetrating my lath, “Two layers of paper and wire.”
I need not only the best Caulking Sealant sold but also to expertly seal my paper to windows, doors, vents, rafters, water spickets, lights, electric outlets, scuppers, by this time I’m sure you get the idea.
This caulking basically fuses the paper to whatever it comes into contact with, and will last longer than old kirk will.

Number 2. The next caulking I show is a Mor-Flexx caulking as it’s really easy to use cleans up effortlessly, and guess what?
It’s works really well, so well in fact that it’s sold at all the professional plastering yards such as Westside Building materials, where they cater to the professional contractor.
Mor-Flexx also has sand in it which matches the majority of stucco finishes we apply, as stucco naturally has sand in too as the aggregate.
“Aggregate is a fancy word for rocks and or sand”
I like the fact that when my brown coat hairlines, notice I said when and not if as this is normal, settling and movement plus curing creates this plus about 50 other natural circumstances.
If the new stucco finish is going to be painted this caulking is super easy to apply and blends in perfectly, even by inexperience guys or gals.
FYI, most Tile or Grout caulkings work similarly as well, as they too have sand, so no need to panic if you can’t find Mor-Flexx.

3. The last one I show although it engineered for outside repairs we use for interior cracking on interior gypsum plaster walls (or I should say Jason uses) is the 40 year Alex plus which is an acrylic, latex caulk plus silicone, it blends in super easy to interior gypsum plaster.
A DIY home owner can use your finger, putty knife, trowel, or even a paintbrush to feature this calking in to the existing wall.
TIP, don’t spin your wheels and buy the 35 let alone 25 year same brand caulking or more than likely it will shrink, what happens if this catastrophe happens?
Nothing, you just have to re-caulk over the shrunken stuff.
Why does every home on the planet eventually hairline and or crack inside?
Gypsum does not flex to much so if your home is 1 to 100 years old or older, the natural occurrence of rain for a day to 30 days or longer will expand the earth and guess what?
(What goes up must come down) or when the ground finally drys out the home will settle.
You can’t see this action, but new hairlines in a wall will tell you that this happened.
Next, factor in natural phenomena such as earthquakes, super high winds, not as in hurricanes but high winds, tsunamis,
(o.k. I made that one up, if there a tsunami the last thing to worry about is a crack)
While were at it let factor in heavy and or large slamming doors and windows, heavy traffic driving in the streets, there are about 50 other real factors which causes cracking but this is the short list.
Bottom line is Vibrations and or movements to concrete, stucco or plaster is like Kryptonite to superman.

With a bit of attention with interest you too can connect the dots in understanding the basic principles and techniques of which caulkings to purchace for stucco or plaster cracks and realizing what extremely simple methods are available for you to use, this know how can be used to save you some cash.
Or if you do the work yourself your physical efforts will help create a sense of euphoria which provides a peaceful nights sleep knowing, “Yeah Baby” I did these simple caulking repairs myself.
What more does a righteous person wish?

Old Kirk says, material knowledge is 70% of being a well rounded stucco guy,
The other 30% is application.
