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.
Caulk that utilizes silicone or latex is best for bathroom use. Silicone formulas (like GE Advanced Silicone caulk, available on Amazon) provide a stronger seal against moisture, but latex tends to be easier to work with.
What kind of caulk do you use in the bathroom? The best caulks for tubs, sinks, or shower stalls come in tubes labeled “Tub and Tile” or “Kitchen and Bath.” These are either acrylic latex or silicone compounds that have been chemically tweaked to resist mildew and to stick to smooth, nonporous surfaces.
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.
Don't use latex caulk to fill cracks in tiles or to fill in missing grout. This leads to a bigger problem down the road. Silicone — Best for large cracks or joints around bathroom and kitchen fixtures. Silicone will keep its seal when the joint, crack or gap stretches or compresses.
It is recommended to replace the caulk in your bathroom every 5 years, even if it isn't showing signs of wear and tear. By maintaining and replacing your caulking regularly, you prevent damage that may be caused by peeling, cracking, mold or mildew. Fortunately, replacing caulk can be a quick and easy job!
Is silicone or acrylic caulk better? Silicone is your go-to whenever you're sealing something water-related—bathrooms, kitchen fixtures, bathtubs, even fish tanks. Acrylic is a good general-purpose sealing substance, perfect for tiny gaps between baseboards and chair rails.
If the shower has a glass door that needs to be caulked, you'll want a clear formula. White caulk on any glass fixtures can look out of place and disrupt the flow of the room. Additionally, clear caulk can look very nice on shower fixtures and back plates, especially if they're made from metal.
Water gets stagnant in the gaps and leads to mold development. You will find mold and mildew on caulk and on the corners often due to this dampness. Mold and mildew when left ignored lead to respiratory and eye problems along with reeking a foul odor.
Can I apply new silicone atop, or alongside old silicone caulk? It is recommended that any old silicone is removed. While new, freshly applied silicone can be applied & will bond to old silicone – the bond isn't as strong as if it were applied to a clean surface.
Silicone and Caulk are both commonly used as sealants, but they are not the same thing. Caulk is composed of silicone components but the difference lies in elasticity. Using silicone as a sealant will provide objects with more flexibility; the ability to expand and contract freely.
The key difference between the two is the material compound. Plumber's putty is soft sealing material and that means it won't harden over time, making it easy to disassemble or remove after several years. Silicone on the other hand, dries up and hardens over time, making it difficult to remove or work with again.
How often should you re silicone? Silicone sealant products generally last fifteen plus years before you need to consider re siliconing. This of course is also dependent on how much moisture the sealant sits in, how long it takes to dry and how clean the room is with the sealant.
Refreshing caulk every year or so goes a long way to preventing water damage and mildew. Caulking a shower or tub is an easy DIY, too—here's how to get the job done like a pro.

Acrylic Latex Caulk *Plus Silicone - In my opinion this is the minimum standard of sealant that should be used for interior painting project applications such as the joints where baseboards, door & window casings, and crown moldings meet the walls.
Caulk is used to fill in the gaps between tile and fixtures (such as a bathtub or sink) or the floor and wall. Unlike grout, caulk is not used between the tiles, except where a vertical and horizontal tile surface meet, such as between a tile shower floor and tiled walls.
The key distinction between caulk and sealant? Elasticity. Caulk is typically made from a mixture of latex and acrylic materials, which make it more rigid and prone to shrinking when cured. A sealant offers superior elasticity and water resistance because it primarily contains silicone.
