What is the Best Silicone Sealant (For Every Use)?

If you are looking for a sealant that is flexible, yet powerful and resistant to harsh weather conditions, water, chemicals, and more, we have just the solution.

Silicone sealants can bond to many common materials including plastic, metal, glass, ceramic and more. They tend to have a gel-like consistency and must be left to cure for a minimum of 24 hours. This requires patience, but their long service life more than makes up for it.

Choosing the right silicone caulk for your project can be difficult since there are so many different ones. Here are the best silicone sealants for every use.

Best silicone sealant for outdoor use

Silicone is waterproof and helps the seal last longer even in direct sunlight or rain, which makes it ideal for multiple outdoor projects. Simply make sure to watch out for the weather at the time of application since temperature may influence the adhesion.

Best sealant for windows and doors

Sealants should always be used around your home where different materials meet, such as around doors and windows. Low modulus neutral silicone sealants are ideal since they offer better adhesion and accommodate more movement.

Our industrial grade Adseal 4600 is a great option as it comes in multiple colours and offers excellent adhesion to masonry, aluminum and more. It is also very resistant to UV rays and can be used both indoors and outdoors.

Glazing silicone also cures with a very clean finish and offers good adhesion to glass, so it can be used to seal around the edge of glass in windows and doors.

Best sealant for decks

Sealant is necessary for decks to prevent water infiltration and keep moisture out. This prevents your wood from rotting and increases its lifespan. Make sure your deck is thoroughly cleaned and debris is removed before applying the sealant.

You should choose a silicone sealant that is very resistant to mold and mildew since these are the worst enemies of outdoor wood.

Best sealant for concrete

Concrete is porous and therefore holds moisture, so it is recommended to seal your concrete driveway. Sealing outdoor concrete is an essential part of home maintenance, especially after a few years of exposure to different weather conditions and UV rays.

A good concrete floor sealant can preserve its appearance and make it more resistant to stains, damages or moisture problems.

Best silicone sealant for bathrooms

Bathroom sealants have to be resistant to mold and mildew. A silicone sealant with fungicide reduces mold, especially if the area you are sealing is highly exposed to moisture.

Using silicone caulk specifically for showers and bathtubs, such as the Adseal 4800 for kitchen and bathroom, is therefore extremely important to prevent moisture damages

Best silicone caulk for showers

Caulking needs to be done around shower doors, walls, handles and pans. Your sealant needs to be flexible enough to move with the weight of the person in the shower and the movement and closing of the doors.

Pure silicone caulk adheres well to most shower and tub materials, such as porcelain, ceramic, stone, fibreglass and glass. It is very durable and rarely cracks with expansion.

Best silicone caulk for bathtubs

High modulus silicone is more rigid once cured and therefore ideal for bathtubs. Once filled with water, your bathtub gets weighed down. Low modulus silicone may tear and cause the bath to leak, whereas a high modulus sealant will be more stretchy and flex back as the bathtub moves.

Best sealant for countertops

Silicone sealants are ideal for most kitchen renovation projects, including countertops.

High modulus acetoxy silicone sealants are commonly used since they cure quickly and result in a very rigid seal. Many homes used to be equipped with latex sealant, but it is not as durable and can become discoloured over time. If this is your case and you are planning to renovate your kitchen or redo the caulking, choose a 100% silicone sealant.

Countertops are usually very visible, so you want to make sure they look well-maintained. Other types of sealants may be more likely to crack or get black and moldy in a short amount of time, which will ruin the look of your countertops.

Silicone sealants can be used for different countertop materials such as quartz, granite or between backsplash tiles. They are also non-toxic, food-safe and can be chosen in a colour that matches the look of your countertops.
