Sealants are an essential component in construction. They are also crucial in many commercial and domestic environments. Here, we are going to show you everything you need to know about its importance and how it can help you.
What Is Sealant in Construction?
Sealants are used in construction as a method to prevent substances and fluid from passing through surfaces, openings, or joints. They can also prevent air, dust, and other debris from passing through. Sealants are used to close any form of opening that is too small for other materials like timber, mortar, or concrete.
What Is Mastic Sealant Used For?
There are many different types of sealants, from acrylic to silicone, as well as polysulphide and fire-resistant, but mastic sealant is a type of sealant in liquid or thick glue or paste form. Mastic sealants are used to join one surface to another and protect the area where it is applied.
Mastic sealants are beneficial because they stay flexible after curing, making them ideal for projects that require the joints and surfaces to have some degree of movement. This is why it works very well with a variety of materials around the home, including in the bathroom, and is used to fix materials as diverse as glass, wood, and concrete.
