Best Kitchen Silicone for Installation & Care: 2025 Expert Review
DR Joinery
Expert Joiner & Kitchen Specialist
Water ingress is the silent killer of any kitchen, especially in the older terraced properties we see so often around York where damp can already be a battle. A failed silicone seal behind a sink or worktop can lead to blown chipboard and rot within months.
However, 'kitchen silicone' isn't just about the sealant. As a joiner who takes pride in installing flawless oak and laminate worktops, I also look for products that help homeowners maintain that finish. Using the right silicone accessories can add years to the life of your kitchen surfaces.
In this review, I am looking at three essential silicone products: a trade-standard sealant for robust waterproofing, a clever pressure-pack option for difficult corners, and a high-quality silicone utensil set that I frequently recommend to clients to protect their new installation.

Specs vs. The Real World
The Spec: "'Anti-Mould' Guarantee"
"Manufacturers often claim their sealant will prevent mould growth indefinitely."
In York's humid climate, no sealant is magic. 'Anti-mould' means it contains a fungicide that delays growth, but without regular cleaning and ventilation, mould will eventually return. Regular maintenance is key.
The Spec: "Touch Dry in 20 Minutes"
"You can use the sealant area shortly after application."
Whilst the skin might form quickly, the core takes much longer to cure. If you splash water on it too soon, you risk compromising the adhesion. I always advise clients to leave the sink alone for a full 24 hours to be safe.
My Top 3 Recommendations
Three options to cover different needs and budgets
UniBond Anti-Mould White, Waterproof Mould Protection, Long-lasting White Silicone Sealant for Kitchen & Bathroom
Unibond
This is the bread-and-butter product for any joiner. If you already have a sealant gun, this cartridge offers excellent value and professional performance. It provides a robust, waterproof seal that is essential for bridging the gap between worktops and tiled splashbacks.
The Good
- Excellent adhesion to tile and laminates
- Anti-mould formula helps in humid kitchens
- Cost-effective for larger jobs or full kitchen refits
The Bad
- Requires a sealant gun (sold separately)
- Can be messy if you are inexperienced with gun control
Installer Tip:
When applying this along a worktop, fill the bath or sink with water first if you are sealing around them. The weight opens the gap slightly. If you seal it empty, the silicone might pull away when the sink is full heavy use.

Whilst not a sealant, this set is my top recommendation for protecting your investment. After spending thousands on a bespoke kitchen installation, the last thing you want is scratches on your new surfaces. High-quality silicone utensils like these are heat resistant and gentle on both your pans and your wooden or stone worktops.
The Good
- Protects expensive worktops and cookware from scratches
- High heat resistance ensures they don't melt on pot rims
- Hygienic one-piece design avoids food traps
The Bad
- Black silicone can show water marks if not dried properly
- Hand wash recommended for longevity of the wooden handles (if applicable) or steel shine
Installer Tip:
I always suggest clients switch to silicone tools immediately after a new install. Metal ladles dropped on an edge can chip even the hardest granite or dent solid oak. These soft-edged tools eliminate that risk completely.

If you need to re-seal a small area behind a tap where a standard gun won't fit, or if you simply don't own a sealant gun, this compressed air pack is brilliant. It allows for a continuous bead without the hand strain or the physical bulk of a cartridge gun.
The Good
- No additional tools or gun required
- Compact size fits in tight spaces behind taps
- Easy to control flow speed with the trigger
The Bad
- Much more expensive per kg compared to cartridges
- Smaller quantity - only suitable for small repairs, not full kitchens
Installer Tip:
The pressure in these cans is great, but ensure the surface is bone dry and grease-free before starting. Use masking tape on both sides of the gap to ensure a neat line, as the flow can be faster than you expect with a pressure pack.
