Waterproofing: How To Pick The Right Sealant For Your Project

If you’re working on a new home project or it’s time to do a bit of touch up and maintenance work on existing structures, you may well encounter a situation where you need to ensure that joints, cracks or parts need to be completely watertight.

While there are many excellent waterproofing sealants available, it’s essential to know which type is best suited to your particular situation. Read on to discover the main types of waterproofing sealants in Sydney and their prescribed uses.

Silicone Sealants

By far the most commonly used type of sealant, silicone is an excellent material to ensure that water doesn’t penetrate any part of your structure. Not only is it waterproof, but it’s also a great choice if you want to protect a form from heat damage and offers UV resistance.

This type of sealant is typically used for sealing up cracks in bathrooms and kitchens, securing windows to frames, and it is one that works great on most surfaces including metal, wood, plastic, ceramic, porcelain and granite. It’s also best suited for automotive projects due to its tolerance to high temperatures.

Silicone is not adhesive when it comes to painting, so if you’re looking for a sealant that you can conceal with a fresh coat of paint, you’d be better off using another type.

Polyurethane Sealants

As is the case with silicone, polyurethane is also extremely versatile and can be used for most applications around the house. An added benefit is that it can be used as an anti-corrosive agent to prevent rust formation in metal.

There is also a variant available that can be used to seal wooden floors. It doesn’t easily suffer damage from abrasion, which makes it ideal for high traffic surfaces. Polyurethane sealant can be painted over without hassles, so it’s perfect for those jobs where you want to seamlessly conceal patch-up work and the colour scheme of the surrounding area.

Bituminous Sealants

Mainly used for industrial and construction purposes, a bituminous sealant is exceptionally hardy and can tolerate extreme temperatures, pressure and abrasion, making it ideal for outdoor surfaces such as concrete paving. It is also a popular choice for coating your roof to insulate against water damage.

We hope this information will guide you to make the best choice for your home improvement project.
