Ensure fast and effective seals with the UniBond Speed Seal Sealant – our fastest drying sealant yet. Ideal for warm and humid environments, the silicone sealant is suitable for showers, bathrooms, kitchens, baths, tiled areas, sinks or basins and also works as a worktop sealant and toilet sealant. The superior sealant provides hygienic, waterproof and mould resistant seals for sanitary applications by creating a flexible barrier from water. After applying with the sealant tool, it can be exposed to indirect water contact after just 1 hour and is fully dry after 24 hours, meaning your bathroom can be back in use in no time.

To apply: Ensure the area being sealed is clean, dry and free of old sealant, grease and dirt. Cut the tip off the cartridge above the screw thread. Remove the nozzle cap and trim the nozzle at an angle of 45 degrees to the desired joint width. Screw the nozzle onto the cartridge and insert the cartridge into the gun. Apply by pulling the trigger. Starting in a corner, work along the length of the area to be sealed in a smooth continuous movement. Keep the nozzle in contact with both sides of the joint as a guide. To maintain a mould-free finish, we recommend regular cleaning of the sealant to remove residues of soap and other toiletries which can provide a starting point for mould growth.
