Learn more about sealant application

We’ve used our expertise as sealant application specialists to put together a guide to sealant application which covers all the basics. Whether you want to know more about the process, or you’re unsure about what the right service for your needs is, we’ll fill in the gaps! Read on to learn more:

What is mastic sealant?

Generally speaking, the two main sealing applications are the joining of one surface to another, and providing protective cover to a particular area. (We would know, the SD Sealants team are specialists in both!) Mastic sealant is a type of sealant used in projects where the sealant needs to stay flexible once it’s dried, as it can maintain its durability for years while also bending as required.

Our team commonly uses mastic sealant in construction jobs to connect doors and windows to the main structure, as well as in bathrooms to seal the area around tubs or to fill in cracks in masonry. Incredibly versatile, it adheres to a range of materials, including concrete, steel, aluminium, wood and glass.

Mastic application

Roofing and brick structures are usually subject to mastic application, along with some cars and boats, where it provides surface protection and keeps them free of dust. Regardless of the type of surface you are applying the mastic sealant to, there are a couple of things to remember.

While priming the area before mastic application is not necessary, it’s good practice to ensure that it’s been thoroughly cleaned and dried. (As SD Sealants’ specialist team do at all times!) As most mastic sealants come in a tube or tub, the best tool to apply them with is the trusted caulking gun. The average lifespan of mastic sealant is approximately five years, so we recommend replacing it after that period to ensure optimal efficiency.

Mastic or silicone sealant?

There are a number of unique features which set mastic sealant aside from other alternatives such a silicone. Combining a smooth surface with a rigid form and unrivalled flexibility, mastic sealants are easy to apply, as they come in a pasta shape which applies to the surface smoothly without need for priming.

In our experience working on different projects, we’ve also found that mastic is perfect for outdoor sealant application thanks to its ultraviolet (UV) inhibitors, which help keep it from weakening in the sun, as well as its waterproof properties and weather resistance. What’s more, unlike some of their counterparts, mastic sealants are great for use on metals, as they don’t cause corrosion.

However, there are also a couple of downsides to mastic sealants to be aware of. Despite its exceptional flexibility, we don’t recommend using it on areas where it will be subjected to extreme join movement, as it will eventually wear down. We also advise using mastic for thick sealant applications such as wider cracks in masonry or large gaps, as it’s not best suited for areas requiring a delicate finish.
