Sealants that work as hard as you do
Created for applicators – by experts who understand the job
On site, there’s no time for second chances. You need sealants that work – fast, clean and reliably.
Whether you’re sealing floor joints in a warehouse, housebuilding on a construction site, applying finishes in changing weather or working with unpredictable substrates, you need external silicone sealants and anti pick mastic products that perform consistently – first time, every time.
Your on-site challenges – our solutions
We design and manufacture our products with professional applicators in mind – because we understand the pressures you face on-site and what you need from the products you use every day – whether internal or external silicone sealants or anti pick mastic.
Tight deadlines & fast turnarounds
Projects often run on tight schedules, leaving little room for delays caused by slow curing times, rework or product issues.
Variable site conditions
Work in environments with fluctuating temperatures, humidity and exposure to dust, moisture and wind – all of which affect sealant performance.
Diverse substrates
Jobs involving multiple surface types (concrete, metal, plastic, wood, glass), require a versatile sealant that adheres well to all without constant primer changes.
Demand for clean finishes
The quality of the visible sealant line is critical, especially in high-spec or exposed joints – which is why you need smooth tooling and a professional finish.
Physical strain & efficiency
Manual application can be repetitive and physically demanding. You need sealants that are easy to gun, apply and tool – especially on larger jobs.
Movement and durability expectations
Sealants are often used in expansion or movement joints – which is why they must be flexible and long-lasting under mechanical stress, weather, UV and traffic.
Health, safety & environmental constraints
From a health and safety perspective, there’s growing demand for low-VOC, solvent- and isocyanate-free products that are safer to handle and compliant with regulations.
