STEP 1

Prepare the surface

Remove the old sealant, dirt, and loose particles with a sealant-removing tool (knife) and clean the area with a cloth moistened with white spirit. To ensure you apply an even bead of silicone rubber sealant, apply masking tape along the joint to form edges for the sealant. Put a single long strip on either side of the joint where you’ll be applying the silicone sealant. This will keep the sides of the sealant neat on the window frame.
