Reseating Beam Pads
After years of use the contact between the beam and the beam pad can deteriorate, resulting in reduced platform stiffness. To reseat your pads you will need the following: White Gelcoat, masking tape, mould release wax, sandpaper, acetone and a 50mm paintbrush.

Follow these steps (do one beam at a time so that you have enough time before the Gelcoat gels):

1. Remove the beam by undoing the beam bots and pulling the beam out.
2. Briefly sand the beam pad to rough the surface and thoroughly clean beam and beam pad with solvent.
3. Wax the beam anywhere it touches the beam pad or gelcoat might touch it (follow the waxing
   instructions on the packaging).
4. Mask up the edge and area around the beam pad where you don’t want gelcoat to be
5. Mix gelcoat and brush a 2mm thick layer onto the beam pad leaving a 10mm gap around the bolt holes
6. Bolt the beam back into place before gelcoat cures
7. Clean off any excess gelcoat with acetone
8. Repeat on other beam

By waxing the beams you should be able to remove them if you need to, however they will be quite stiff to do so.
