Frequently Asked Questions

Is mastic the same as silicone sealant?

Mastic and silicone sealants are both used to fill gaps and seal joints, but they have different properties and applications. Mastic is generally more flexible and suitable for a wider range of materials, whereas silicone is best for areas exposed to high moisture.

What is mastic used for in construction?

In construction, mastic is used for sealing windows, doors, and other openings, as well as for waterproofing, glazing, and sometimes in flooring and tiling applications.

What is the life expectancy of mastic sealant?

The external life expectancy of mastic sealant can range from five to 20 years, depending on the material composition, application, and environmental exposure.

What thickness of mastic sealant to use?

The required thickness of mastic sealant varies based on the application and gap size. It's essential to follow manufacturer recommendations and industry standards for optimal performance.

Can you mastic over old mastic?

While it's possible to apply new mastic over old mastic, it's recommended to remove the old material first to ensure a clean, secure seal. Proper preparation and application are key to the longevity of the seal.
