Suretherm Paint is a high-performance, insulating wall coating engineered to combat condensation, mold growth, and heat loss in homes and commercial spaces. Formulated with advanced microsphere technology, it creates a thin, thermal barrier on interior surfaces that reflects heat back into the room—helping maintain warmer walls, reduce energy consumption, and improve overall comfort.

Unlike standard emulsion paints, Suretherm actively works to keep surfaces above dew-point temperature, dramatically minimizing the buildup of moisture that leads to black mold and damp patches. Easy to apply with a brush or roller, it offers excellent coverage, a durable matt finish, and long-lasting protection.

Whether you’re renovating a problem area or looking to enhance the energy efficiency of your property, Suretherm provides an effective, user-friendly solution that blends seamlessly into any décor

While it comes in white as standard, Suretherm once applied can then be wallpapered over or even painted over using any emulsion paint.

The main uses for Suretherm are:

Bathrooms and wet rooms
Kitchens
Areas where mould grows (mould must be cleaned off the surface before applying Suretherm)
Cold walls and ceilings
Areas of missing insulation
Industrial applications including shipping containers
Prefabricated structures including internal surfaces

Application

Ensure the area is well ventilated before applying. Stir gently and thoroughly before use. DO NOT use a powered mixing paddle as this will impact the performance of the coating. Ensure application temperature is between 5-25°C. Surfaces should be clean, dry and free from grease and dirt. Remove all loose and defective paint and lightly sand glossy areas with sandpaper. Any visible mould should be cleaned with Suretherm Preparation Treatment Spray. Apply two coats of Suretherm, allowing 4 hours between coats. The coating should be touch dry in 2 hours depending on humidity and temperature. Allow for extra drying time in cold and wet weather conditions. For best results, use a medium pile roller. New plasterwork should be allowed to dry completely before applying Suretherm.
