What is mastic sealant used for?

Mastic sealant fills gaps and prevents water, air, or dirt from entering cracks around windows, doors, bathrooms, kitchens, and external areas.

What is the difference between mastic and silicone sealant?

Mastic sealant is generally more flexible and paintable, making it ideal for interior gaps and joints.

Silicone sealant is waterproof and more durable for wet areas like bathrooms and kitchens, but it can’t usually be painted over.

How long does a mastic seal last?

A good-quality mastic seal typically lasts 5–10 years indoors. Its lifespan can be shorter in areas exposed to constant moisture or sunlight.

Is mastic sealant waterproof?

Yes, most mastic sealants are designed to be waterproof, protecting surfaces from water damage. Some types are specially formulated for wet rooms, bathrooms, and external use.

What will mastic adhere to?

Mastic can stick to a wide range of surfaces, including wood, plaster, tiles, glass, metal, and some plastics.

That said, it works best on clean, dry surfaces for a long-lasting seal.

Where can I use mastic sealant?

Mastic sealant is flexible and waterproof, meaning you can use it everywhere, from the bathroom to the roof. Here are some common uses:

  • Windows and doors
  • Sinks, showers, and baths
  • Pipes and gutters
  • Vents
  • Roof flashing
  • Gaps and cracks

Is mastic sealant easy to apply?

Mastic sealant can be applied yourself, but getting a neat, even finish is quite a knack.

Corners, curves, and tight spaces can be tricky. That’s why many homeowners prefer to hire a tradesperson for a smooth, long-lasting seal.
