Mastic Man Romford 

Mastic and sealants play a crucial role in projects, but their importance is sometimes overlooked. 
Sealant can serve different purposes in various projects such as installing a new bathroom in a house, working on a large commercial project, or an outdoor high access surface. Its main goal is to create a barrier that can prevent water and air from penetrating and discourage bacteria growth. 
Applying a professional sealant to a surface or joint can offer durable protection and improve the aesthetics of the area.

What is a mastic man? 
A mastic man has the expertise to apply silicone in the appropriate colour, using the correct tools and materials, to any joint or surface. 
What is silicone? 
Silicone is a man-made substance that has different colours and remains flexible. It is great for sealing joints that are prone to moisture because it can resist mildew and doesn't let water through. It's important to note that the strength of Low and High Modulus silicone can differ. 
What is the difference between low and high modulus? 
Low modulus silicone and high modulus silicone have varying tensile strengths. Low modulus sealants are better suited for outdoor usage because they can adapt to expansion joints that undergo greater movement. Conversely, high modulus sealants are best for interior joints and contain anti-fungicides that prevent bacterial growth in moist areas, such as bathrooms. 
What types of materials can you work on? 
We are able to work on a variety of materials such as metal, glass, finished walls, armor coating, tiles, internal surfaces, vinyl, natural stone, timber, brick work, as well as structural and external surfaces. 
How much does a mastic man cost?
