Proper preparation
The main reason sealant fails is poor preparation. A good contractor removes old sealant completely, cleans the joint and primes where necessary. Skipping this step saves time on the day but costs money later.
Correct product selection
Commercial work uses different products for different joints. Silicone, polyurethane, polysulphide, hybrid and acrylic systems each have their place. The contractor should select the right sealant for the substrate, joint size, movement and exposure, based on manufacturer guidance.
Site discipline and documentation
On commercial sites, turning up on time, working safely and providing risk assessments and method statements matters. Insurance should be in place and available on request.
