Mastic Man Croydon 

The function of mastic and sealant is invaluable, yet it is often not given enough credit in projects. 
Sealant can be used in various projects such as installing a new residential bathroom, working on a large-scale commercial project or an outdoor high access surface. Its purpose is to create a barrier to prevent external forces like water and air, and stop bacteria growth. 
Applying a professional 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 possesses the necessary expertise to apply silicone on any joint or surface using the suitable colours, tools, and silicones. 
What is silicone? 
Silicone is a synthetic compound that comes in various colours and doesn't harden. It's ideal for sealing moisture-prone joints because it's waterproof and mildew-resistant. However, the tensile strength of Low and High Modulus silicone varies. 
What is the difference between low and high modulus? 
Low modulus silicone and high modulus silicone differ in terms of their tensile strength. Low modulus sealants are more suited for outdoor use as they can accommodate expansion joints that undergo greater movement. High modulus sealants, on the other hand, are optimal for use in interior joints and contain anti-fungicides to prevent the growth of bacteria in damp 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? 
We offer reasonably priced services as a mastic man and can give you a free quote at your location without any obligation. It is strongly advised to hire a professional silicone applicator to avoid any damage to your newly installed surfaces.
