It provides a hygienic barrier from water by creating a permanently flexible seal, allowing water contact after only one hour. A strong mould protection silicone sealant, it is specially formulated for use in warm and humid environments such as showers, bathrooms, and kitchens. An ideal sealant solution where resistance to mould growth is necessary, this long-lasting sanitary seal is perfect for your bathroom repairs. How to use: To gain a perfect seal, you must first 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. Then run the sealant around the edge and leave to dry with the bath still full until the sealant is completely dry. 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.
