Mastic Man Bromley 

Mastic and sealant is an often under-appreciated component of any project, but its function is invaluable. 
Whether it's in the installation of a new residential bathroom, a large scale commercial project or an outdoor high access surface, sealant provides a non permeable barrier between external forces such as water and air whilst preventing bacteria growth. 
A professionally sealed surface or joint can offer years of protection whilst improving the overall aesthetic of the area to which it has been applied.

What is a mastic man? 
A mastic man can use the appropriate colours, silicones, and tools to apply silicone to any joint or surface you need. 
What is silicone? 
Silicone is a type of synthetic compound that does not harden and is available in different colours. It is waterproof and resistant to mildew, and often used for sealing joints that are prone to moisture. The tensile strength of Low and High Modulus silicone differs. 
What is the difference between low and high modulus? 
The difference between low and high modulus silicone is their tensile strength. Low modulus sealants are suitable for outdoor use as they allow for more movement in expansion joints. On the other hand, high modulus sealants are used for interior joints and contain anti-fungicides to prevent bacterial growth in damp-prone areas like bathrooms. 
What types of materials can you work on? 
We can work on all types of materials including: metal, glass, finished walls, armour coating, tiles, internal, vinyl, natural stone, timber, brick work, structural and external. 
How much does a mastic man cost?
