Dowsil Silicone Sealant at MyToolShed.co.uk
Dowsil silicone sealants are professional-grade products for glazing, bathroom, kitchen, outdoor and mirror-fixing jobs. Each formula is designed for a specific task, so you can match the sealant to the substrate and the environment instead of settling for a general-purpose tube.
Whether you are a glazier, fitter, builder or maintenance contractor, you can choose from acetoxy and neutral-cure options that give a clean, durable, long-lasting seal.
Dowsil Silicone Sealant Features and Benefits
- Strong adhesion: Bonds to non-porous surfaces such as glass, aluminium, painted surfaces and composite boards, giving a reliable seal on mixed-material jobs.
- Ageing resistance: Resists shrinkage, cracking and discolouring, so joints stay neat and watertight for longer.
- Neutral-cure formulas: Suited to sensitive materials where a low-odour, non-acidic sealant is preferred.
- Bacteria-resistant and food-grade options: Help keep bathrooms, kitchens and food areas hygienic.
- Weatherproof performance: Handles outdoor exposure without losing flexibility.
