Silicone Sealant TECMAXX SMAR 250 ml with Applicator, brand TECMAXX

TECMAXX SMAR silicone sealant in a 250 ml cartridge with applicator is a ready-to-use neutral silicone designed for general sealing and bonding tasks. The cartridge format with an applicator provides controlled extrusion and smoother bead formation, making it suitable for sealing joints around windows and doors, sanitary fixtures, and other construction or repair points where a flexible, weather-resistant seal is required. The neutral cure formulation reduces the risk of corrosion on adjacent metal surfaces and is compatible with many common building materials.

Advantages

TECMAXX SMAR offers flexibility after curing, maintaining joint integrity during thermal movement and vibration. The applicator ensures accurate, mess-minimised application and consistent bead size. The cured silicone provides long-term resistance to moisture, UV exposure and common weathering factors, while neutral cure chemistry minimises odour and adhesion-related corrosion risks on metal and coated surfaces.

Suitable for

• Sealing joints around windows and external doors
• Sanitary sealing around sinks, bathtubs and showers
• General gap sealing in façades and trim work
• Bonding and sealing where a flexible, weather-resistant joint is required

Key specifications

• Volume: 250 ml cartridge with applicator for controlled extrusion
• Curing type: neutral cure silicone suitable for use on metals and coated surfaces
• Elasticity: remains flexible after curing for thermal and mechanical movement
• Resistance: moisture-resistant and UV-stable for external and internal applications
• Application temperature: suitable for typical construction site temperatures (refer to manufacturer guidance on optimal temperature range)

How to use

Ensure joint surfaces are clean, dry and free from dust, oil or loose material. Cut the cartridge tip to the desired bead size and attach the applicator. Apply the sealant evenly into the joint, maintaining steady pressure on the cartridge to form a continuous bead. Tool the joint within the skin formation time to achieve a smooth finish and ensure good substrate contact. Allow the sealant to cure fully as specified by the manufacturer before exposing the joint to water or heavy loads.

Usage recommendations

For best results, apply TECMAXX SMAR at recommended temperatures, avoid application on wet or frosty surfaces, and test compatibility on painted or sensitive substrates before full application. Use appropriate joint design and width-to-depth ratio for optimal movement accommodation and longevity.
