When working on at-home repair or construction jobs, you always want to make sure you have exactly the right materials for the job. But with so many options for sealant tape on the market, it can be tough to know which one is right for your project.<\/p>\n

For building a new deck, you’ll want to ensure that the timber is protected by a sealant to extend its lifetime as long as possible. Continue reading below to learn how butyl rubber tape is the superior weather-resistant adhesive to silicone tape.<\/p>\n

What is Butyl Tape?\"\"<\/strong><\/h2>\n

Butyl tape<\/a> is a rubber-based adhesive developed to augment its traditional rubber counterparts. Butyl can withstand extreme temperatures and maintain its stickiness at much colder temperatures than natural rubber.<\/p>\n

It also has an instant initial stickiness to almost any surface and adheres well. Because of this, it makes for a great problem-solver when you need to repair in a pinch. It’s also very flexible, making it reliable when moisture is a factor, such as outdoors on your deck.<\/p>\n

Butyl tape is the go-to sealant for many RV campers and boat enthusiasts because of its resistance to water and weather. It also works well and sticks to glass, metal, and timber, serving as an excellent tool for repairs or a deck’s substructure.<\/p>\n

What is Silicone Tape?\"\"<\/h2>\n

Silicone tape is a readily available sealant and bedding compound. Adhesive to fibreglass, metal, timber, rubber, and vinyl surfaces, it takes 24 hours to cure. Made from cured silicone rubber, it has a thin silicone gel layer that fuses and forms a permanent bond to the applied surface.<\/p>\n

However, silicone sealant has some disadvantages that make it unsuited for long-term projects or fixes. For example, many find silicone putty tape difficult to remove due to the bond it forms, which can create an even worse mess. The applied surface is also prone to absorbing some residual silicone that is squeezed out from under the hardware. It can also be a huge project to remove all the old silicone you once applied before re-bedding.<\/p>\n

While typically cheaper than butyl tape, it also can dry out fairly quickly, which will reduce the integrity of your seal over time. Silicone fixes might be a good short-term fix, but they typically need to be resealed again in about a year.<\/p>\n

Silicone vs. Butyl Tape<\/a> Comparison<\/h2>\n

Which option is best comes down to the project you have at hand. While silicone provides a quick and cheap repair, butyl tape offers a much longer-lasting and more dependable seal. Adhesion, flexibility, and durability make butyl tape the best option for many repair and construction projects. Whether you’re working on leaks in your boat or mobile home, installing new windows or repairing a windshield, blocking minor leaks in water pipes, or repairing an EPDM rubber roof, butyl tape is the superior choice. However, for repairing old windows that have new leaks, silicone caulk or butyl caulking can be easier to apply. Butyl tape can also withstand circumstances of extreme temperatures or moist environments.<\/p>\n
