Why Every Home Needs To Replace Silicone Sealant With Mould-Resistant Sealant

Have you noticed your existing sealant has become mouldy over time? Has its strength weakened, and cracks are starting to show? If so, it may be time to replace your silicone sealant with mould-resistant sealant that will not turn mouldy or crack over time.

Traditional silicone sealants come with a host of defects and problems, which is why more people are turning to mould-resistant sealants such as the revolutionary TRIBRID® sealant, BT1. Before we get into the miracle sealant that is BT1, let’s go over a few reasons why it’s time to replace silicone sealant with mould-resistant sealant.


Strong Odours

One of the most common complaints when it comes to silicone sealants is the odour. Most, if not all, silicone sealants have a very strong odour, which makes the application process more difficult. Some of these smells will even linger long after the job is done, which only adds to the frustration. BT1 is free from awful odours, which is a pleasant relief when it comes to carrying out different applications around the house.


Long Cure Times

Silicone sealants are known for their slow curing times. You may be waiting for what feels like forever for a silicone sealant to fully cure, which in our busy world, is definitely not ideal. For faster and higher-quality results, choose BT1. BT1‘s full cure time is just 24hrs, which is very fast compared to traditional silicone sealants.


You Can’t Paint Over Silicone Sealants

When you use silicone sealants, you’re pretty much stuck with the colour of the original sealant forever because you cannot paint over these sealants. Thankfully, BT1 can be painted. But you need to wait until the sealant is fully cured before applying the paint. We recommend using common water-based paints and to stay away from Alkyd paints for the best possible results.



One of the most frustrating things about silicone sealants is their inability to resist discolouration. The original appearance of the sealant will not be the final result in a few months down the line. Chances are, the sealant will lose its colour and since you can’t paint over silicone sealants, you’re stuck with the discolouration until you decide to replace it with a new sealant.


Cracks and Shrinkage

Due to chemicals, environmental influences, and other conditions, silicone sealant often softens, cracks, or shrinks over time. As a result, the bond grows weaker and begins to chip away. You might find that the bond fails altogether, requiring a complete overhaul and re-work. Like CT1, BT1 will not shrink or crack over time. It is able to bond most substrates such as wood, brick, metal, glass, ceramics, and many more without cracking or deteriorating over time.


Develop Mould

Silicone sealants are prone to mould because they cannot withstand bacteria or resist mould infestation. This leads to black and spotty sealant that triggers health issues such as coughing, irritated skin and eyes, runny noses, and amplified symptoms of asthma. BT1 is a mould-resistant sealant that reduces bacteria by up to 99.99%!
