Exceptional Internal Mastic Services by Mastic Global

At Mastic Global, we pride ourselves on the quality of materials we use, particularly for internal mastic applications. As your trusted London mastic man, we specialize in both domestic mastic man and commercial mastic man services, ensuring excellence in every project.

Our sealants are high-quality, flexible curing silicone rubbers, ideal for environments where food contact is possible and condensation is frequent. This makes them perfect for kitchen and bathroom applications. Each sealant is infused with fungicides, providing resistance to mildew and mould growth, and ensuring a clean and hygienic finish.

The mastic (silicone) we apply is a part acetoxy rubber sealant, known for its strong adhesion to various non-porous surfaces. It’s non-staining and includes food-grade fungicide, making it safe and durable.
