Mastic Man Harlow 

Mastic and sealant play an important role in projects, but they are sometimes underappreciated. 
Sealant serves as a protective barrier against external elements like water, air, and bacteria growth. 
It can be applied in different types of projects, whether it be installing a new bathroom at home, working on a large commercial project, or a surface that requires high access outdoors. 
Using professional sealant companies to apply a seal to a surface or joint can provide long-lasting protection and enhance the appearance of the area.

What is a mastic man? 
A mastic man has the knowledge and skills to correctly apply silicone to any joint or surface using the appropriate colours, tools, and silicone types. 
What is silicone? 
Silicone is a man-made substance that is available in different colours and won't become hard over time. It's suitable for sealing joints that are likely to have moisture because it's waterproof and resistant to mildew. However, it's worth noting that the tensile strength of Low and High Modulus silicone differs. 
What is the difference between low and high modulus? 
Low modulus silicone and high modulus silicone are different because of their tensile strength. Low modulus sealants are recommended for outdoor usage because they can handle expansion joints that undergo substantial movement. High modulus sealants are best suited for interior joints and contain anti-fungicides to prevent bacteria growth in damp places such as bathrooms. 
What types of materials can you work on? 
Our services cover a wide range of materials such as metal, glass, finished walls, armour coating, tiles (internal), vinyl, natural stone, timber, brickwork, structural, and external. 
How much does a mastic man cost?
