Our verdict

If you need a dark grey sealant for your kitchen or bathroom, the current price of £6.97 makes this an exceptional buy. The hybrid formula offers real advantages over standard silicone — better flexibility, paintability, and adhesion — plus it's anti-mould and eco-friendly. With 4.4 stars from over 2,900 reviews, it's clearly a product that works well. The only real downsides are the limited colour and the small tube size for large projects. At 53% off, this is a pricing glitch worth grabbing quickly if you have a sealing job coming up.

Editorial review

If you're planning to reseal your kitchen or bathroom, now is a surprisingly good time to pick up a tube of Hemway's anthracite grey hybrid polymer sealant. Normally priced around £14.95, it's currently available for just £6.97 — a saving of over 53%. That's a genuine discount worth considering before the price adjusts.

This sealant isn't your standard bathroom silicone. It's a hybrid polymer that combines the flexibility of silicone with the paintability of acrylic caulk and the grab strength of an adhesive. You can even apply it underwater without releasing plasticisers, and there's no need for primer. The waterproofing is reliable, making it suitable for shower trays, kitchen sinks, and around baths. The anti-mould technology helps prevent that unsightly black growth that often plagues high-moisture areas, keeping the dark grey sealant looking fresh for longer.

Using it is straightforward with a sealant or caulking gun. A 300ml tube gives you roughly 9.25 metres of 3mm bead, and curing takes 24 to 48 hours depending on bead size and conditions. It's also eco-friendly: odourless, solvent-free, and non-toxic, with an ultra-low VOC rate. Hemway is a British brand, and the quality stands up well in practice.

With over 2,900 reviews averaging 4.4 stars, this is a popular choice. At this price, it's a no-brainer if you need a reliable grey sealant for a renovation or repair.

Price trend

Hemway normally sells this hybrid sealant for £14.95, but it's currently listed at just £6.97 — a drop of £7.98 or 53% off. That's a significant saving for a well-rated product. Given the discount size and the brand's popularity, this feels like a pricing glitch that won't last long. If you've been looking for a grey bathroom sealant, now is the time to buy.
