Changing a latex neck seal

Whether the neck seal has been glued on the inside or out side of the suit the principles the same.

You can either remove the old seal and tape entirely, or cut the old seal off at the edge of the suit, leaving a band of the old rubber still glued to the suit. It is usually best to remove the tape from the inside suit that is over the suit and seal join. To remove tape start at the glued down end and apply heat with a hair dryer or hot air paint stripper on its lowest setting. Be careful not to burn your fingers or the suit. Using long nosed pliers or forceps will make this easier. Once the end is loose work back along the tape trying not to pull so hard as to break it. Be careful not to burn your fingers or the suit with to much heat.

If you cut the old seal off, be careful not to cut the suit. You will be gluing the new seal over the band of old rubber.

If removing the whole seal simply soften the glue by the gradual application of heat, or solvent. Either process will cause the glue to soften, and the old seal can be peeled off carefully. Much more care must be taken when working with neoprene suits as the nylon burns more easily and if too much solvent is used then the nylon will delaminate from the neoprene center. Inserting a piece of cardboard or wood inside the suit makes gluing easier and prevents glue getting were it is not wanted, the neck hole of the suit can be held to the board by double sided tape. If a neoprene hood is attached then this should be turned inside out or a board with a hole cut in it used. Make sure that the seal is the right way round. The shiny side is the outside of the seal and the duller side the inside of the seal that when wearing is against the skin.

Position the new seal on to the neck seal former using double sided tape to keep it in position make sure that the edge of the is pulled out to the edge of the ring. A light rubbing with sandpaper will give a better key for the glue, then wipe down with solvent.

Practice positioning the new seal on its ring onto the suit draw round the ring to give a guide to glue to, add 12.5mm all around if 25mm tape is to be added around after.

Mix up the S5001 glue as instructed on tin. Coat the areas to be glued on suit and seal with S5001 using a brush. Leave until to become touch dry, about 10-15 minutes. Apply a second coat and allow to become touch dry.

Lower the former ring with attached seal down into the correct position, press down hard to get the glue coats to bond, peel the ring away carefully. Use the roller to gently work out any bubbles or wrinkles, making sure the seal sits flat on to the suit.

If required the suit/seal edge should be over taped. Cut a piece of 25mm tape to the correct length, allowing a 20mm overlap. A 30mm band should be coated with glue centered on the top edge of the seal also coat the cut tape on the textured side.

Allow glue to become touch dry and then re-coat. Wrap the tape around in the correct position. Apply some glue to the area below the overlap, and stick down when touch dry.

The seal should remain on the board for at least 1 hour to allow the glue to cure.

Once the glue is dry, remove the board carefully. If the seal has stuck to the former use a brush soaked in solvent to dissolve away the glue.

To tape the seal joint turn the suit inside out and repeat the process for taping above after wiping the area with solvent.

Check the edges of the seal and tapes by picking at them with your fingernails. If any area comes up, reapply a small quantity of glue to the lifting area.

Excess glue can be rubbed off with a little solvent on a cloth.

Dust the area with talc.

Suit can be used in 3 hours with care, but full strength is after 24 hours.

Mixing glue

Bostik 2402should be used as a two-part system; the correct ratio is 100:6 by weight
(approx. 100:5 by volume). If a thinner mixture is required add 20% T559. Stir very
well with a mixing stick. If not mixing a full 250ml of glue in its can, then use mixing
cups designed for the purpose or a clean and dry glass jar, do not mix in plastic cup as the solvents present will melt them.
The pot life of mixed glue (parts A and B) is 6 hours at 20 °C.
