When choosing a kitchen silicone sealant or bathroom silicone sealant, durability and waterproof protection are essential. Hemway’s Kitchen & Bathroom Sealant is specifically formulated for high-humidity environments where condensation, water exposure and temperature changes are common. Ideal as a bathroom silicone sealant for showers, baths, basins and toilets, it performs exceptionally well as a shower silicone sealant and bath silicone sealant, creating a strong, flexible and waterproof seal. It is equally effective as a kitchen silicone sealant around sinks, worktops and splashbacks, helping to protect against leaks and moisture damage. If you are searching for silicone sealant bathroom solutions, silicone bathroom sealant or waterproof bathroom sealant, this advanced formula delivers dependable, long-lasting performance.

Our hybrid polymer technology combines the flexibility of traditional silicone sealant with the paintability of acrylic caulk and the ultra-high bonding strength of adhesives. The result is a waterproof silicone sealant that resists mould, shrinking and cracking over time. Its anti-mould and stain-resistant properties make it particularly suitable for bathrooms, wet rooms and kitchens where hygiene and appearance matter. Designed to remain effective in temperatures ranging from -50°C to 120°C, it forms a durable seal that stands up to everyday use. It cures within 24–48 hours depending on conditions, achieving full cure in 24 hours at 23°C and 50% relative humidity, and offers approximately 9.25 metres of coverage with a 3mm bead.

For larger projects and more demanding applications, Hemway’s Construction Sealant provides exceptional strength and versatility. Suitable for both professional tradespeople and experienced DIY users, this silicone sealant is ideal for interior and exterior use. It performs reliably as an outdoor silicone sealant waterproof solution and is well suited to silicone sealant outdoor projects including doors, windows and structural joints. If you require an exterior silicone sealant or external silicone sealant waterproof option, this high-performance formula delivers long-lasting protection against the elements. Its chemical and UV-resistant properties help maintain both performance and finish, even when exposed to sunlight or harsh conditions.

The sealant adheres to a wide variety of materials including flooring, ceilings, drywall, concrete, stone, PVC, wood, metal, glass, mirrors, plastics and synthetic surfaces. As a paintable silicone sealant, it allows for seamless finishing, while its non-shrink formulation ensures joints remain strong and flexible over time. One of its most innovative features is its ability to cure underwater for structural bonding in closed-face applications such as swimming pools, without releasing harmful plasticisers when exposed to water.

Low odour, non-toxic and low VOC, Hemway’s formula is more environmentally responsible than many traditional silicone sealant products and is safer and more pleasant to use indoors. Whether you are looking for bathroom sealant, bathroom silicone, kitchen silicone sealant, shower silicone sealant, outdoor silicone sealant or a reliable construction sealant, Hemway’s Premium All-In-One Hybrid Polymer Sealant & Adhesive provides a professional-quality, waterproof and durable solution for sealing and bonding across a wide range of applications.

FAQs

What is a hybrid polymer sealant?

It is a next-generation alternative to traditional silicone. It combines the flexibility of silicone sealant, the paintability of acrylic caulk and the high bonding strength of adhesives. Hemway hybrid polymer sealant delivers a durable, waterproof and mould-resistant seal that can be used in bathrooms, kitchens and construction settings.

What should I use to seal my bathroom?

For bathrooms, you should use a high-quality bathroom sealant that is fully waterproof, mould-resistant and flexible, such as Hemway’s Kitchen & Bathroom Sealant. It is specifically designed for high-moisture environments such as showers, baths, basins and toilets, making it an ideal shower sealant and bath sealant for long-lasting, professional results.

Can I put bathroom sealant over old sealant?

For best results, old sealant should always be fully removed before applying new sealant. Applying fresh sealant over old can prevent proper adhesion and reduce durability. Once the old sealant is removed and the area is clean and dry, Hemway waterproof sealant can be applied to create a strong, mould-resistant and long-lasting finish.

Should you fill a bath before sealing it?

Yes, it is generally recommended to fill a bath with water before applying sealant around the edges. The weight of the water pulls the bath into its natural position, helping to prevent the seal from stretching or cracking once the bath is in use. Using a flexible, high-performance sealant bathroom solution like Hemway’s ensures the joint remains strong and watertight over time.

Do you need sealant around the kitchen sink?

Yes, applying kitchen sealant around your sink is essential to prevent water from seeping into worktops or cabinetry. It forms a tight, flexible barrier that protects against leaks, mould and long-term water damage. It's ideal for sinks, splashbacks and countertops, where regular exposure to moisture occurs.

How to apply sealant?

To apply sealant correctly, first ensure the surface is clean, dry and free from dust, grease or old sealant. Cut the nozzle to the desired bead size, apply the silicone sealant evenly along the joint using a sealant gun, then smooth it immediately using a suitable tool. Hemway’s formula can be easily tooled and provides approximately 9.25 metres of coverage with a 3mm bead, helping achieve consistent, neat results across bathrooms, kitchens and construction projects.

How long does sealant take to completely dry?

Hemway’s Hybrid Polymer Sealant typically cures within 24-48 hours, depending on bead size, humidity and temperature. Under standard conditions of 23°C and 50% relative humidity, it achieves full cure in 24 hours.

Is construction sealant waterproof?

Hemway’s Construction Sealant is a durable, outdoor silicone sealant waterproof solution designed for both interior and exterior use. It performs reliably as an exterior sealant waterproof option, offering strong adhesion, UV resistance and long-lasting protection in demanding environments.

What are common mistakes when caulking?

Common mistakes include applying sealant over old material, failing to properly clean and dry the surface, cutting the nozzle too wide, or not smoothing the bead immediately after application.
