Alcolin has a wide range of sealants, for home and construction applications. These top-quality products are all manufactured explicitly with a specific purpose in mind. When choosing your sealant, it is best to know the exact use so that you select the right product for the problem you need to fix.
Choosing the right product for a particular problem is vital as it will otherwise be a futile purchase with potentially damaging results. All Alcolin products are specifically designed for a particular use; thus, interchanging one for another will not always work effectively. For this reason, getting to know your products and familiarising yourself with their benefits is prudent.
Although there is a wide variety of sealants in the Alcolin range, we have chosen the four most widely used, to familiarise yourself with.
