A silicone sealant, or caulk, is a heavy-duty and gel-like adhesive used for construction and home improvements. Due to its flexibility and durability, it is often used in different applications for both interior and exterior parts of a house or a building. Just like with other adhesives, there are different types of silicone sealants that are formulated for different projects.

Here are a few things you need to know about silicone sealants so you can make the right decision.
Silicone sealant has been in use for a very long time and its primary goal is the same: to keep moisture or air from getting in or out. It seals the gaps between two surfaces or materials in the strongest and most efficient way possible.
Silicone caulk is a popular sealant primarily because of its flexibility. It is very elastic yet can withstand heat and cold, making it ideal for any repair and construction project . Curing time can be a bit longer than other adhesives, some types up to 24 hours, but the result is worth the wait. The LePage 2 in 1 Seal & Bond Kitchen and Bath Express Silicone Sealant is an exemplary example of one that is fast-drying at only 2-hour time.
If there is a crack, you can caulk it. A silicone caulk is an adhesive that is very useful to have in the household to fix cracks or gaps. It can be used on the following materials or surfaces:
If you want your silicone adhesive to match the color of the material you will be applying it on, you should choose a silicone sealant or caulk that has the same color. This is because you cannot paint over silicone.
Second, silicone sealants are not designed to hold extremely heavy loads. That is why you must never use it on load-bearing structures.
Finally, read the instructions carefully as there might be additional preparations that you will need to do before you can apply the sealant. This is especially true if you are working on wood or metal surfaces.

In the silicone and sealant world there are a lot of competitors. Products with similar labels, almost identical, can often act in very different ways. Here are some things to consider when picking your next silicone or sealant.
Make sure your silicone is VOC compliant. This is a fancy way of saying there are no solvents or isocyanates in the silicone…in other words it is nature friendly.
Do your research and make sure the formula is pure, and that the supplier is reputable. It is easy to put “100% Silicone” on a label, often this is not the case. Additives are used to dilute the formula, manipulate the properties, or alter the immediate value of a product. When this happens inaccurately, or at the expense of the customer, formulas can become brittle after curing, they can yellow in color, they can delay the cure time to three or even four days, and they will always underperform when compared to a pure or professionally mixed formula. You know you are using an inferior product when:
Adding compounds to formulas isn’t always a bad thing! But it has to be left to the experts. When it is appropriate, chemists will add compounds to formulas to increase their adhesion properties, paint ability, or even extend their use life. Most commonly, these products are used when painting is needed. In this case our modified polyurethane is often used because this hybrid material combines technology to produce a material with many of the same characteristics of silicones and polyurethanes but with better performing characteristics and paint ability.
