CEMEDINE SU-001 Modified Silicone Sealant for Construction Joints

CEMEDINE SU-001 Modified Silicone Sealant is a one-component white sealing material designed for multipurpose interior and exterior construction joints. Supplied in a 333 mL cartridge, it cures by reacting with moisture in the air and forms a durable, flexible seal around gaps, seams, and joints. Its strong adhesion allows it to work not only as a sealant but also as a practical bonding material on compatible building substrates. This makes it suitable for contractors, maintenance teams, renovation professionals, and property owners who need dependable gap filling and weather-resistant joint protection.

The paste consistency supports controlled application with a standard cartridge gun and helps the material remain in place on vertical and horizontal joints. CEMEDINE SU-001 Modified Silicone Sealant is the white version of the CEMEDINE Super Seal range. Its clean appearance is useful around walls, panels, frames, stone, and other visible construction details where a neat finished line is important.

Key Benefits of CEMEDINE SU-001 Modified Silicone Sealant

CEMEDINE SU-001 Modified Silicone Sealant combines broad adhesion with high durability and weather resistance. CEMEDINE identifies the cured material as hard and abrasion resistant, making it useful for joints exposed to rubbing, cleaning, or everyday contact. The formula also provides anti-mold and antibacterial properties, helping improve performance in areas where cleanliness and moisture management are important.

Official product data lists a typical density of 1.39 g/cm³ and a touch-dry time of approximately 45 minutes at 23°C. The sealant can be painted after curing, providing flexibility when the joint must match surrounding walls, panels, or architectural finishes. Water-based paints are recommended. Oil-based, phthalic, and alkyd coatings may dry very slowly or remain tacky, so they are not suitable over the cured sealant.

Applications for CEMEDINE SU-001 Modified Silicone Sealant

CEMEDINE SU-001 Modified Silicone Sealant is recommended for multipurpose interior and exterior joints. Typical uses include sealing gaps around building panels, wall interfaces, frames, stone elements, concrete-related details, exterior repair areas, and other construction joints requiring dependable adhesion and weather resistance. Its strong bonding ability may also help stabilize small trim pieces where a flexible adhesive seal is preferred.

For a 5 mm wide by 5 mm deep joint, one 333 mL cartridge provides an estimated application length of approximately 12 meters. For a 10 mm wide by 10 mm deep joint, the estimated coverage is about 3 meters. Actual coverage depends on bead shape, joint preparation, dispensing control, and material waste. Users should test adhesion on the actual substrate, coating, and surface condition before large-scale work.

How to Apply CEMEDINE SU-001 Modified Silicone Sealant

Before applying CEMEDINE SU-001 Modified Silicone Sealant, remove dust, oil, moisture, loose particles, old sealant, and other contamination from the joint. Apply masking tape along both sides when a clean edge is required. Cut the nozzle slightly wider than the gap, install the cartridge in a suitable sealant gun, and fill the joint completely from the bottom to reduce voids.

Tool the surface immediately after filling because the product forms a skin quickly. Remove the masking tape before the surface hardens and leave the joint undisturbed for approximately 24 hours. Because atmospheric moisture is required for curing, deeper sections may need more time. When painting is required, CEMEDINE recommends applying a compatible water-based coating between 24 hours and seven days after sealing at 23°C.

Storage and Safety of CEMEDINE SU-001 Modified Silicone Sealant

Store CEMEDINE SU-001 Modified Silicone Sealant in its original sealed cartridge away from direct sunlight. Official handling guidance recommends storage between 5°C and 35°C in a cool, ventilated area. Wear suitable gloves and eye protection, use the product with adequate ventilation, and review the latest safety data sheet before professional use.
