Mould resistant bathroom sealant

Mould on bathroom sealants is a problem that can be avoided by using to correct bathroom sealant. The 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.

The easiest way to avoid mould growth on a bathroom sealant it to use a good quality sealant like Adiseal. Adiseal 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.

Another way to avoid mould growth on bathroom 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 bathroom 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 bathroom sealant.

If you do get mould on the bathroom sealant then there are ways to remove it. Have a look at our other tips to find out how.

As well as Adiseal being free of solvents & isocyanates, Adiseal also has the lowest VOC (volatile organic compound). Adiseal has the top EC1 Plus certification for this.
