Anti Mould Sealant

Mould Resistant Sealant

Mould on a sealant is a problem that can be avoided by using to correct mould resistant sealant. One problem with silicone sealants is that they contain solvents. The cheaper the sealant, the more solvents in the product.

For the silicone to cure, the solvents have to evaporate away leaving microscopic holes for bacteria and fungal spores to get into and multiply with moisture. Silicone sealants that claim to be mould free contain anti-fungal and anti-bacterial agents, but these have a limited life.

Adiseal mould resistant sealant & adhesive does not contain any solvents. It cures from outside in, meaning the outside creates a skin first before the inside cures. As it does not contain solvents it does not have the same problem as silicon sealants, where the solvents leave microscopic holes.

How to avoid mould growth on sealants

The easiest way to avoid mould growth on a sealant it to use a good quality anti mould sealant like Adiseal mould resistant sealant & adhesive. This anti mould sealant does not contain any solvents or isocyanate. Adiseal cures from outside in, meaning it forms a skin on the outside first then cures inwards leaving no microscopic holes for the bacteria or fungal spores to get into.

One other way to avoid mould growth on sealants is to keep the sealant dry but this can be difficult in a bathroom or kitchen that is being used a lot.

Another way to avoid mould on a sealant is to clean it on a regular basis with a bleach based cleaner. This will kill bacteria and fungal spores reducing their numbers and so avoiding mould growth on the sealant.

Best mould resistant sealant test

To find out what the best mould resistant sealant is, we carried out several tests including a mould resistance test. The mould resistance test was carried out by applying sealants from different manufacturers inside new clean plastic cups then filling the cups half way with tap water. Each cup was then covered and kept in the same conditions, so as to be fair to all the products being tested. As can be seen in the image, the best sealant was Adiseal again where it had the strongest mould resistance from the sealants tested.

Mould resistance test result

In the above image even after 90 days of being submerged in the same tap water, both the sealant & water are still very clear in the Adiseal cup compared to other products. One of the competitors product being tested, claimed to be the No.1 adhesive and sealant. This other product which is more expensive than Adiseal, didn’t perform as well as Adiseal in the mould resistance test. Unlike the competition Adiseal doesn’t just claim to be the No.1, Adiseal can prove it.

As well as Adiseal having the strongest mould resistance, Adiseal also seals instantly, works in the wet & even underwater.
