How to Replace Laytex Dry Suit Seals | Expert Advice

Doing drysuit repair work on a once 100% waterproof garment may seem like something you can only leave to the pros, but as you will see here, it’s a pretty straight forward job.

All you need is the proper drysuit repair materials and a little bit of know-how. I recently had to replace the wrist seal on my suit so I put together a video showing the steps for replacing a seal. The same technique works for any of the seals on a dry suit.


Here’s what you will need..

  • Aquaseal Glue and Cotol Accelerator combo pack (yes, both. You’ll thank me later.)
  • A small container for mixing – say maybe a crumbled blue cheese container?
  • A pair of latex gloves are recommended
  • Something from around the house to fully expand the drysuit opening – more on that in the video.
  • A Replacement Seal – sizes range from XS – XL

Since drysuit seal damage is rarely planned upon, its a good idea to go with the glue and accelerator combo pack. Cotol acts as a cleaner and an accelerator all in one. Its a really useful tool for seal repair since it cuts the drying time down from a full 24 hours to being able to set sail within 2-3 hours.

Another thing you will want to remember is to leave the sleeve and replacement seal stretched out while drying. For stretching out the neck, a basket ball will work quite well. For the sleeves, a flexible cutting board or soda bottle can do the trick.

  1. Hi,
    After several unsuccessful hours of trawling the web for DIY seal replacement tips, I eventually stumbled upon this gem of a video.
    Just used it to replace a wrist seal on my trilaminate dry suit. Fingers crossed that it works – I have to go diving in a few days.
    Big time kudos for taking the time to make and post this video.
    Peace and Tranquillity,

  2. Aquaseal is one of the worst things you can use if you ever need to replace your seal again. Use a flexible contact cement preferably heat cured. Aquaseal will void any warranties you have, and many shops that do this professionally will not work on suits that have been glued in this fashion.

  3. We've had good experiences with Aquaseal in the past with employees and fellow sailors, but always welcome product suggestions with an email to

    We have found with our manufacturers that Latex seals are generally not covered under warranty and the Aquaseal at the cuff would have no impact on the warranty of the rest garment (zippers, fabric, seams).
