KITCHEN & BATHROOM ACETIC CURE

Bostik Kitchen & Bathroom AC is an acetic (acetoxy) curing silicone sealant built to handle everyday wet area conditions. It seals joints around showers, bathtubs, glass screens, and kitchen and bathroom fixtures, and its standout trait is how clear it stays over time compared with other silicone types, so seals keep looking neat well after installation.
It's a natural fit for darker bathrooms and laundries where a crisp, non-yellowing finish matters, and for jobs on non-porous surfaces like glass, ceramics, and laminate. It cures fast and holds its seal in hot, humid environments where lesser sealants fail.

Why choose Kitchen & Bathroom AC?
This sealant is built with an active fungicide, so it resists mould and mildew even under prolonged heat and humidity. It flexes with the building, handling ±25% joint movement without cracking or losing its seal, and it doesn't sag or slump once applied, so vertical joints stay clean and even. It also carries excellent UV and ozone resistance, keeping its clarity and flexibility under sustained light exposure. Kitchen & Bathroom AC is WaterMark approved.

Where to use it
Kitchen & Bathroom AC is suited to glass-to-glass screens, ceramic tiles, laminate, fibreglass, rimless sinks, and vitreous toilet pans, as well as general bathroom and kitchen fixtures. It's not suitable for marble, granite, or other natural stone, nor for aquariums, structural glazing, underwater or below-grade use, horizontal trafficable areas, or contact with copper, brass, or concrete.

TIP: Working around metal fittings, concrete, or stone where acetic cure could cause staining or corrosion? Reach for Kitchen & Bathroom NC instead. Its neutral cure formula protects those sensitive substrates, while the AC formula is the better all-rounder for glass and ceramic wet areas.
