Quick Answer
To keep wounds dry in the field, apply a waterproof dressing or waterproof tape over the wound, and seal the edges with silicone-based sealant. Use a breathable dressing like gauze under waterproof dressings to prevent moisture buildup. Ensure the dressing is not too tight to maintain blood flow.
Choosing Waterproof Dressings
When selecting a waterproof dressing, consider the type of injury and environment. For minor cuts, use a thin, breathable waterproof dressing like a silicone-coated gauze. For larger wounds or in wet environments, opt for thicker, more robust dressings like hydrocolloid or foam dressings. Always choose dressings that are compatible with the wound type and size.
Applying Waterproof Tape
Apply waterproof tape over the dressing to prevent water from seeping in. Use a strong, waterproof tape like duct tape or medical grade tape. Press the tape firmly onto the dressing, making sure to seal the edges. To ensure a tight seal, apply tape in multiple layers, overlapping each layer by 1/4 inch.
Sealing Edges with Silicone-Based Sealant
To prevent water from seeping under the dressing, apply a thin layer of silicone-based sealant around the edges. Use a small amount of sealant and spread it evenly with a finger or a small brush. Make sure the sealant is not too thick, as this can compromise the dressing’s breathability.
