Will preface this by saying that I’m an RN and certified in WFA. I skip the bandaids, mostly because they just don’t hold up and they let in dirt. I like to use sterile gauze pads with a little antibiotic ointment to keep the pad from adhering to the wound (always apply the ointment to the pad, not to the wound) & leukotape over top it all to seal it on all 4 sides (this all, of course, after cleaning the wound). The leukotape sticks really well (no tincture of benzoin needed; if you’re using regular first aid tape I’d use the benzoin). Cut the leukotape larger than the gauze pad and round off the corners. Leukotape also adheres well in difficult places, like toes, so it’s wonderful for hotspots & blisters.
If you want something waterproof, I’d suggest tegaderm transparent dressings. They can be applied directly over a cleansed wound. My suggestion would be to use these when you’re pretty sure the wound won’t start bleeding again. (So you might start with tape over gauze, then progress to the tegaderm). The nice thing about the tegaderms is that you can see the wound and can thus assess it without taking off the dressing. If you’ve never used one before, I’d suggest practicing before you need one in the field. They aren’t difficult to use, you just don’t want to be fumbling when you really need one.
Yes, stay away from the clotting bandages — actually pressure & elevation of the affected body part is the preferred method of stopping bleeding (assuming we’re not talking about an amputation or crazy arterial bleed). Sometimes the process can take a while — just keep the pressure on.
