If you need to seal junctions between walls and seal cracks in ceilings or walls then it's better to use Caulk because it dries quicker and is much more resistant to weathering and high temperatures.
Latex caulk works well to quickly fill in narrow gaps around doors and windows and even base boards and crown moulding. Expandable foam caulk is a better choice for sealing larger gaps and holes. Use it to insulate areas around pipes and electrical outlets and between window jambs.

The all purpose caulk is effective for hairline stucco cracks and to seal gaps around doors and windows, baseboards, trims and moldings. It is not recommended to water submersion applications, but it is waterproof and has a durability of forty years.
While latex caulk is less expensive and easier to work with, silicone is more durable under extreme weather conditions, and can be used as a binder as well.
Pros of caulk:
Caulk dries quicker than silicone. It's less tolerant to movement than silicone – should only be used in areas where there is little or no movement. Caulk is ideal for filling gaps in living areas like between skirting boards, picture rails and built-in furniture.
Certain places on the exterior of the home should not be caulked, since they'll cut off openings needed for air circulation or drainage. Elegant Painting says these spaces include the gap created when trim boards sit atop the siding, any wood to metal joints, weep holes on windows, and garage door panels.
Silicone caulk is excellent at water sealing and flexibility so it has its place in construction. There are two main places it never should be installed, wood or any painted surface.
Silicone sealant is a great way to fill in gaps between tiles, shower screens, baths and sinks. It also stops water seeping in where you don't want it. We'll show you how to put silicone into a gap using a caulking gun. You will also see how to give your silicone a smooth, professional finish and clean up any excess.
It's great for filling in cracks around doors and windows and useful on non-pours surfaces, including metal and plastic. Silicone caulk can withstand extreme temperatures and temperature changes, so it rarely cracks or breaks. Cons: Silicone caulk can be difficult to apply and does have an offensive odor.
Sanded caulk adheres better to wet surfaces and large gaps than unsanded caulk, but unsanded caulk has a smoother appearance and texture that creates a cleaner finish than the sanded alternative.
Use caulk if cracks appear where the ceiling meets the wall. Caulk is flexible and can withstand a slight bit of settlement. Sand, prime and paint the wall after you've repaired the crack.
Caulk is a flexible material used to seal air leaks through cracks, gaps, or joints less than 1-quarter-inch wide between stationary building components and materials.
It is a flexible material that allows the best possible finish to be achieved by covering cracks, removing gaps and generally creating a neat and tidy edge to interior & exterior surfaces.
Yes, but not if the crack is a deep one.
You need to do something else first in this case. It's OK to use high-quality caulk on cracks up to about 1/8-inch wide and 1/2-inch deep, but caulk alone should never be used to fill larger gaps. Deep or wide crevices should be lined with foam backer rod first.
In general, sealant is the prefered sealing solution for bathtubs and showers, as it is more water resistant than traditional caulk. Silicone sealant forms a watertight seal that is resistant to heavy temperature changes.
One of the major disadvantages of silicone rubber is its poor tear strength. This can be improved with the addition of other ingredients, but it doesn't naturally offer strength or abrasion resistance, so the application needs to be carefully assessed for the suitability of silicone as a solution.
A silicone sealant can last anywhere from 10 to 20 years, depending on the quality chosen and the location of the caulking in relation to the elements, such as the sun and high winds. Silicone caulking offers the best resistance to UV rays.
Yes. We use NexusPro silicone-based sealant to repair and seal concrete cracks, as well as to seal control joints after lifting and leveling the concrete with PolyLevel.
While caulk is long-lasting on solid, unmoving surfaces, silicone sealant's flexibility means it lasts longer in areas with higher moisture. Using silicone sealant in a bathroom for sealing cracks in the tub and shower will create a more durable seal without needing to frequently re-apply.
In response to such problems, the possible reasons are mainly the following two points: one is the construction problem, such as the depth of the sealant apply is not enough, the sealant is too thin or too thin locally, which may lead to cracking; the second is the quality of the sealant itself.
When the caulk gets wet, it will not cure properly. The formula that makes up your caulk will not be able to dry and cure or bond to the surface to that you have applied it. Not being able to dry in a timely manner will prevent the caulk from creating a proper seal.
