A. REPLACING SEALS
1. Remove all the existing seal and adhesive with a sharp blade. Mask off the sealing area with
masking tape or similar (Mask the outside for top frames or reducing windows & the inside for table
seals). Prepare the sealing area with emery cloth or similar to achieve a good surface for the new
adhesive to key with. Ensure that the surface is clean from dust, dirt and grease.
2. Apply a generous bead of high modulus silicone sealant to the masked area and smooth down to
give a consistent layer.
3. Cut the silicone strip in lengths long enough to overlap the corners. Do not stretch the seal strip
when measuring or applying. Lay each strip on to the seal area overlapping at the corners. Ensure
the seal strip is bedded down well by pressing firmly along the full length.
4. With a sharp blade cut a 45° mitre joint at all corners. Fill gaps in the joints with sealant. Remove
the masking tape before the sealant has set. For best performance leave seal to set overnight.
