Sealant applicators seal joints to ensure a building is airtight and waterproof. As a sealant applicator, you could be sealing door and window frames, building facades, or baths and sinks.

You could also be carrying out structural bonding, such as glass to glass seals.


How to become a sealant applicator

There are several routes to becoming a sealant applicator. Many sealant applicators started their career in another area of construction but you can gain the qualifications you need by doing an apprenticeship.

You should explore the options to find out which is the right one for you. Although some of these options will list qualification requirements many employers are more interested in people who are enthusiastic, willing to learn and who are able to follow instructions.

You may need a (CSCS) card to work on a construction site.


An apprenticeship with a construction firm is a good way into the industry. Apprenticeships are open to anyone over the age of 16.

As an apprentice, you will be fully employed by your company and expected to work a minimum of 30 hours a week. Your time will be split between on-the-job experience and a college or training provider.

The (ASA) runs its own apprenticeship scheme. This leads to an NVQ Level 2 in Specialist Installation Occupations Joint Sealant Application.

You’d be an apprentice for two years and this would involve working on the job, with study sessions at the ASA’s own training centre.

You must be at least 18 years old to apply.


The training programme is open to people who have already been working in construction and wish to specialise.

Work experience

Work experience is essential to gaining employment within the construction industry. You could gain this at school, or by working weekends and holidays with a company or relative who works as a sealant applicator.

Potential employers will always be pleased to see work experience listed on your CV.
