Sealants & Mastic

Sealants are used in the construction trade to prevent water and other fluid substances from passing through joints, openings or other material surfaces. However, they are not only used for blocking substances, but they are also very important in some industries for the prevention of air, dust, sound and fire transmission. Furthermore, sealants provide protection from insects, such as around windows and surrounding sinks.

It is important when building in a domestic or commercial setting to use a high-grade sealant product to protect the work from all of the above issues. For example, bathroom construction requires a quality mould-resistant and waterproof sealant to seal gaps and joints, while kitchens also benefit greatly from fungicide treating sealants to stop mould growth and multiplication, as per building regulations. Using a sanitary grade 100% silicone sealant in bath or wash rooms is essential to ensure that it does not shrink over time and allow substances to seep through.

In addition to a kitchen or bathroom sealant, Sovereign produces a high-grade lead sealant which bonds well to metals and masonry. Also available is a flexible, neutral curing silicone mastic for construction applications which is particularly suitable for sealing around doors and windows between the frame and the masonry.
