External silicone sealants & anti pick mastic for professional applicators
On site, there’s no time for second chances. You need sealants that perform – fast, clean and reliably, whatever the conditions throw at you.
Whether you’re sealing floor joints in a warehouse, working on a housebuilding programme, applying finishes in changing weather or tackling unpredictable substrates, professional applicators need external silicone sealants and anti pick mastic products that deliver consistent results – first time, every time.
Hodgson Sealants manufactures a comprehensive range of external silicone sealants, anti pick mastic and related products – all engineered for performance in demanding environments and widely used across construction, glazing and industrial sectors.
Sealant performance you can rely on
Hodgson Sealants’ products for professional applicators are designed to deliver consistent, reliable performance where it matters most. Every product is formulated with the pressures of site work in mind – from tight deadlines and variable conditions to demanding substrates and the need for a clean, professional finish.
Our products support compliance with current health, safety and environmental standards, including low-VOC and solvent-free options for safer handling on site.
Your on-site challenges – our solutions
We design and manufacture our products with professional applicators in mind, because we understand the pressures you face and what you need from the products you rely on every day.
Tight deadlines and fast turnarounds
Projects run on tight schedules. Slow curing times, rework and product failures cost time and money. Our products are formulated to keep your workflow moving.
Variable site conditions
Temperature swings, humidity, wind and moisture all affect sealant performance. Our external silicone sealants and anti pick mastic products are designed to deliver consistent results even in challenging environments.
Diverse substrates
Jobs rarely involve just one surface type. Our sealants bond effectively to concrete, metal, plastic, wood and glass – reducing the need for multiple primers and keeping your kit simple.
Demand for clean finishes
In high-spec or exposed joints, the quality of the visible sealant line matters. Our formulations tool smoothly and consistently, helping you deliver a professional result every time.
Physical efficiency on larger jobs
Repetitive manual application is demanding. Our products are designed for easy gunning and tooling – reducing fatigue and keeping output consistent across a full day’s work.
Health, safety and environmental compliance
Demand for low-VOC, solvent-free and isocyanate-free products is growing – and for good reason. Our range includes options that are safer to handle on site and compliant with current regulations.

Frequently Asked Questions
What is an external silicone sealant?
An external silicone sealant is a flexible, weather-resistant sealant designed for use in joints and gaps exposed to outdoor conditions. It accommodates joint movement, resists UV, temperature variation and moisture, and maintains a durable seal over time – making it suitable for a wide range of construction and industrial applications.
What is anti pick mastic and when do I need it?
Anti pick mastic is a sealant formulated to resist tampering, picking and vandalism. It remains cohesive and difficult to remove once cured, making it the preferred choice for exposed or public-facing joints – such as those in public buildings, transport infrastructure or high-footfall areas – where a standard sealant would be vulnerable to interference.
What substrates do your sealants bond to?
Our products bond to a wide range of substrates including concrete, masonry, metals, plastics, wood and glass. Many formulations offer excellent unprimed adhesion, reducing preparation time and the need for additional primers on site.
How quickly do your sealants cure?
Cure times vary by product and site conditions such as temperature and humidity. Our formulations are designed for fast skinning times to support efficient turnaround on site. Always refer to the relevant product data sheet for specific guidance.
Are your sealants suitable for use in cold or wet conditions?
Our products are formulated to perform across a range of site conditions, including variable temperatures and exposure to moisture. For specific performance data and application limits, refer to the product data sheet or contact our technical team.
Do your products comply with current VOC and health and safety regulations?
Yes – our range includes low-VOC, solvent-free and isocyanate-free options designed to meet current UK and international health, safety and environmental requirements. Check individual product data sheets for specific compliance information.
What packaging options are available?
Our products are available in cartridges, sausages and bulk packaging options to suit jobs of all sizes.
How do I choose the right sealant for my application?
The right product depends on factors including the substrate, joint type, required movement accommodation, exposure conditions and any specific performance requirements such as anti pick properties. Our technical team can provide guidance to help you select the most appropriate product for your project.
