Cromar says the AlphaChem Pure Anti Mould Silicone is a superior quality silicone designed specifically for sanitary sealing and areas of high humidity. Black mould growth is a common occurrence in areas such as these, with condensation being the main cause. To help keep the black mould at bay Pure Silicone has far higher levels of anti-fungal additive than conventional sanitary silicones, which are introduced during the manufacturing process, enabling the product to come with a 10-year guarantee. So, you can be assured that whether you are sealing a new bathroom, or sprucing up an old one, Pure Silicone will stay bright and clean for many years to come. Pure Anti Mould Silicone is available in only the most popular colours: white, clear and ivory and is part of the AlphaChem range of products available from Cromar.
