Bostik Premium 100% Silicone Sealants

by admin2

Silicone sealants can vary wildly in price from different manufacturers and it can be hard to understand why. In fact, there is quite a variety of products on the market and making an incorrect selection on inferior products can be very damaging.

Inferior products often contain fillers or additives that change the composition of the silicone and ultimately affect the performance of the sealant from the moment it is applied. All Bostik silicone products are classified 100% silicone and are designed to weather harsh Australian conditions for years. Bostik’s most popular silicones, Roof & Gutter and Kitchen & Bathroom contain 100% silicone formulas and are built to last in two very different environments and are the trusted choice for professionals.

Bostik Roof & Gutter

Bostik Roof & Gutter has been relied upon by professional plumbers for more than two decades and has stood the test of time. It has been specifically designed for external weather sealing and tested to maintain its performance properties in extreme UV exposure as well as intense cold and snow. Bostik Roof & Gutter exhibits excellent adhesion to a range of cladding and roofing materials including masonry such as terracotta, brick and concrete or decorative sheet metals such as Colorbond® and Zincalume®. These surfaces can be notoriously difficult to stick to due to their protective wax coatings. Bostik Roof & Gutter is also available in a range of popular Colorbond® colours to match whatever finish is desired. Finally, Roof & Gutter has been WaterMark approved and is water potable so safe in contact with drinking water. Bostik’s Roof & Gutter is ideal for all applications exposed to the elements and as a general weather seal in residential and commercial builds.

Bostik Kitchen & Bathroom

When it comes to internal seals, particularly in wet areas such as kitchens, bathrooms and laundries, you can’t go past Bostik Kitchen & Bathroom Silicone. The addition of a fungicide to this sealant makes it ideal for areas that will experience humidity and moisture and with regular cleaning, the seal will resist mould and mildew growth for years to come. Bostik Kitchen & Bathroom is available in two variants: Neutral Cure and Acetic Cure. Each of these has its own advantages suited to specific conditions such as UV exposure or type of substrate (for example, porous stone vs. ceramic). However, just like Bostik Roof & Gutter, both Kitchen & Bathroom NC and AC are highly flexible, durable and WaterMark approved – safe for contact with drinking water.

Although each Bostik silicone has been designed for a specific application or environment, they all share one common trait: 100% silicone content, ensuring they are of the highest quality and performance. Because Bostik silicone is 100% it will not shrink, crack or fade and will retain its physical properties for longer than inferior products. When it comes to choosing a silicone, always go with 100%. To make the choice easy, go with Bostik.
