How to choose the right sealant

As you may expect for a substance used for a variety of different applications, there are many different types of sealant available. This short guide will introduce you to these different sealants, and what each of them excel at.

Sealant is a type of adhesive, which is designed to have a lower strength and higher elongation than ordinary adhesives. This is due to the fact that sealant is utilised to protect and seal a joint between two materials, rather than bond them together. A sealant will form a protective layer, stopping air or water slipping into a joint.

Latex sealants

Generally speaking, a latex sealant is the best friend of the DIY enthusiast. Easy to use and relatively inexpensive, latex sealant is water based and paintable. The water-based composition of latex sealant means it is almost odour free and simple to apply, work into place and tidy up after. Latex sealants are great for many interior finishes.

Roof sealants

When working on a roof, ensuring that you have selected a strong and hardy roof sealant, such as, is vital to ensure that the job is completed in a fashion that is built to last. The heavy nature of roof parts coupled with the battering a roof can get from the weather means that it will need a sealant that is up to the challenge.

Silicone sealants

More difficult to work with than a latex sealant, but featuring enhanced waterproofing, silicone sealants are definitely a favourite in the kitchen and bathroom. Generally speaking, the waterproof nature of silicone sealant makes it a must around sinks, baths and showers, as well as window frames. Silicone sealant is more expensive than latex, and cannot be painted, although it does come in some different colours.

Acoustic sealants

If your home contains a budding Dave Grohl, and your neighbours don’t appreciate drumming, soundproofing is a great option to keep the peace (in more ways that one). When soundproofing a space, using acoustic sealants to help keep panels joined together reduces the noise which would otherwise leak through the gaps. Easy to apply with a caulking gun, acoustic sealants help to absorb sound by remaining fairly soft after they have been applied.

Whatever the job you have planned, there is likely to be a sealant for you, to help you get the job done.
