Product Review: Sanitary Silicone Sealer 310ml (White)

Designed to keep damp areas clean and mould-free

If you’ve ever had to reseal around a basin or shower unit, you’ll know how quickly mould can start to creep in if the sealant isn’t up to the job. The Sanitary Silicone Sealer (310ml, white) is one we regularly recommend to customers who need a reliable, low-maintenance sealant for humid environments.
It’s fungal-resistant and contains a built-in biocide to help prevent unsightly mould growth, ideal for bathrooms, kitchens, and utility areas where condensation and moisture are hard to avoid.
We’ve had plenty of positive feedback from tradespeople and DIYers alike, especially when used around sinks, shower trays, and vanity units. It holds up well over time and looks clean even months after application.

Where it works best

This sealant is compatible with a wide range of surfaces including:

• Ceramics
• Glass
• Sanitary plastics
• Melamine laminates
• Painted timber, concrete, and plaster
• Anodised aluminium and lacquered metals

It’s a great choice for sealing around:

• Worktops
• Basins and sinks
• Shower trays
• Bathroom units

Just a heads-up: if you’re using it on metallised trims, we suggest doing a small test first to check for any discolouration.

Practical, certified, and easy to apply

This product is CE approved and conforms to EN15651-1 and EN15651-3 (F INT, S1). It’s designed specifically for internal use in damp conditions, making it a reliable option for both domestic and commercial projects.
We’ve had contractors tell us they like the way it flows during application, not too runny, not too stiff. It also tools nicely and cures to a clean finish that holds its colour.

A good all-rounder for sealing in damp conditions

To sum it up, if you’re looking for a white silicone that won’t let you down in high-moisture environments, this is one worth keeping on the van. It’s straightforward to apply, sticks to all the right surfaces, and does what it says on the tube.
