Why You Should Choose a Good Silicone Sealant

You should choose the right silicone adhesive based on the material you’ll be working with. Acid-cure and acetoxy silicone sealants work best on non-porous surfaces, such as glazed tiles and glass, but can corrode metal or etch plastics. Neutral-cure varieties are a good option for metal or wood, and they’re less likely to release an unpleasant vinegary smell during the curing process.


One of the primary reasons silicone sealants are popular is their durability. They are able to withstand high temperatures and resist the effects of aging, vibrations, and shock. They can also be used on a variety of different materials, including metals and plastics. They are even resistant to harsh chemicals. This makes them a great choice for electrical sealants and around flammable materials.

When selecting a silicone sealant, be sure to choose one that is compatible with your surface material. You can find products that are designed for use on glass, glazed tile, aluminum and many other types of surfaces. You can also find sanitary silicone sealants, which are formulated to resist mold and mildew growth. These are ideal for use in bathrooms and kitchens.

Additionally, you should consider the consistency of the silicone sealant. There are low-viscosity formulas that are thicker and slower to dry, as well as high-viscosity formulas that are thinner and faster to dry. The viscosity of the sealant will determine how much force is required to stretch it, so it is important to choose the right type for your needs.

Another factor to consider when choosing a silicone sealant is its temperature range. Some silicones are formulated to be resistant to extreme temperatures, making them an excellent choice for automotive applications. For example, high-temperature silicones are often used in engines and transmissions because they can withstand high temperatures without melting or aging.


Unlike most adhesives, sealants and caulks, silicones retain their elasticity once dry, which makes them ideal for areas that experience heavy expansion and contraction, like bathroom gaps. They are also resistant to extreme heat and cold, making them a good choice for outdoor applications or projects that will be exposed to a range of temperatures.

Another reason why silicones are so popular is because they’re a lot easier to clean than acrylic sealants. Silicones are generally non-toxic and won’t grow mould, and most can be easily removed with a little household bleach and cotton wool. However, you should choose a silicone that’s anti-fungal for long-lasting protection. In addition, good quality silicone sealant it’s a good idea to use a fungicidal silicone for projects that require regular contact with water, such as around bathtubs and showers.

For projects that will require high-temperature resistance, a high-strength silicone is a must. You can find these products at hardware stores and most auto parts suppliers. The J-B Weld 31314 and the Permatex 81730 are two of the best options for this purpose, as they form a strong, durable seal even in extremely harsh environments.

Pure 100% silicones, such as good quality silicone sealant the XtraBond 250 anti-microbial and mildew resistant RTV silicone sealant, are the most durable and expensive, but they’re also one of the best choices for a variety of situations. Acetoxy silicones have a distinct vinegar-like smell during application, while oxime silicones have a neutral aroma.


The rubbery consistency of dried silicone sealants makes them an excellent material choice for creating hardwearing and long-lasting seals and bonds, especially in areas or environments where the bonded surfaces may move, either through mechanical force or due to expansion and contraction of materials caused by moisture and temperature changes. Silicones also provide good cushioning between surfaces liable to come into contact and therefore reduce the chance of damage or abrasion.

This makes them particularly popular for bathroom and kitchen seals, although they are also often used on glass and metal bonding in craft projects, pet or terrarium projects and even on some vehicle components such as car doors and windows. It is important to make sure you buy the right silicone sealant for your job as different types have different properties. For example, some sealants are formulated to be mould-free and anti-fungal, while others are designed for use with natural stone (such as marble or granite) without discoloring it.

Other things to consider when buying silicone sealants are their shelf life and application methods. It is important to choose a tube that is still potent and not out of date, as old sealants will lose their adhesion qualities. Also, if you want to apply the sealant by hand, it is important to learn how to do it properly so you can create neat joins and beads with no bleeds.


A quality silicone sealant is an expensive investment, but one that will last for a very long time. It will also save you money in the long run by keeping moisture and air from seeping into areas that shouldn’t be sealed. Silicones are also very effective at keeping cold air out of your home, which can help you save money on heating.

Silicones are also very versatile and can be used in many applications. They are waterproof and bond well with a wide variety of surfaces, including plastics. They are also resistant to chemicals and abrasions. They can even be used to repair leaky water systems. They are also very useful for sealing around windows and doors to prevent cold air from entering your house.

When buying a silicone sealant, choose a brand that offers a guarantee. Usually, a warranty will cover up to one year and will be free of charge if you encounter any problems. This will give you peace of mind, especially if you are doing a large project.

You should also make sure that the sealant is pure. Acetoxy silicones will have a strong vinegar smell during application, while oxime silicones have a more neutral smell and are better in every way, from adhesive strength to suitability for different materials and resistance to ozone and UV radiation.
