Masterseal provides a high performance fire resistant intumescent compound.
A general purpose hole and gap filling sealant for use in masonry or plasterboard constructions and for areas around door ironmongery where excess timber has been removed prior to fitting. It can also be used for gaps in ceilings and walls up to 25mm. When gaps are filled from both sides, the fire resistance is generally doubled. Non-toxic, it can be overpainted and gives an easily tooled smooth finish.
FEATURES & BENEFITS
Masterseal is one of a number of specially formulated compounds with intumescent properties for use in a range of gap sealing applications.

Masterseal has achieved a 60 minute rating in tests by various test houses.
