Plumber using a silicone-based sealantsDuring construction and repairs, you can use sealants to prevent the passage of air, dust, heat or moisture through your building’s seams and joints. If you want to target moisture specifically, then a waterproofing sealant is your best option. The experts at Waterproofing Direct list some common varieties of waterproof sealants.

Silicone-Based Sealants

This sealant is among the most popular types for waterproofing. Aside from preventing water from destroying your property, it can offer protection from extreme temperatures and UV rays. Silicone-based sealants provide extra protection from mould and you can use them on stone and marble without worrying about stains. Its main disadvantage, though, is that you cannot paint over them, although some specialised silicone-based sealants have other materials mixed into them to allow you to paint over them.

Polyurethane Sealants

These sealants allow you to paint over them to blend them with your surrounding décor. Abrasion and shrinkage rarely spoil the material, making it ideal for use in both cars and flooring. However, polyurethane sealants have a shorter lifespan compared to those made of silicone and cannot endure extreme temperatures or UV rays. They are also not quite as eco-friendly.

Bituminous Sealants

Some varieties of these waterproof sealants can withstand extreme temperatures and are fuel-resistant, but bituminous sealants are not suitable for flooring. Builders often use these to seal concrete roads and airport decks. In residential properties, they are ideal for roofs and around water tanks.

Other Sealants

If you don’t want your sealant to be visible, clear sealants are available for use. You can also use tinted sealants to enhance the natural beauty of wooden floors. These can also protect your floors as they are usually resistant to mildew.

Knowing the different sealants to choose from can help you get the right sealant when looking for waterproofing sealant supplies in Sydney. Feel free to ask an expert if you’re still unsure of which sealant can best serve your purpose.
