Cut the joint on both sides with a Stanley knife.
Remove difficult residues with a sealant scraper.
Slightly roughen the edge with a cleaning sponge.
Degrease the bath with household ammonia.
Tip: Let it dry properly. If necessary, slightly heat with a hair dryer.
Apply the tape on the bath and wall, approximately 2 to 3 mm from the centre of the joint.
Tip: In the case of unstable baths (slightly wobbly), fill the bath full of water so the weight creates the maximum joint width.
Apply plenty of sealant evenly along the joint.
Tip: Hold the Power Pistol at an angle of 45 degrees. Work from a corner, with the oblique side of the nozzle pointing downwards.
Tip: If necessary, use a new nozzle for the correct diameter.
Remove the tape.
Finally, gently smooth off the sealant by running a soapy finger along it.
Admire the result!
