Everyone is different....but this is my "method".
My "bags" are one piece and have the karaya seal.....you do not have to use paste. I do use an Eakins cohesive seal because I do not have a wash board tummy....despite my best efforts of course
I also have tried the hair dryer trick on occasion.....on cool. But I also have used the powder....I think it is Karaya Powder. I take a bath/shower, remove bag before or sometimes during, I only use the adhesive remover to take off the excess at first.....but then let my bath take off the adhesive wipe residue. I think that sometimes that contributes to it not sticking good if that is a problem.
When I am out of the tub I dry the area well.....but gently. Air dry seems to be best for me.
I do the same wash rag trick many of you seem to use. I have my bag ready to go usually.
It has backing that peels off the plate. I slap the cohesive seal on and then slap it on me.
That's a "gentle" slap......I mean it is quick.
I always wear a belt.....for security. I have had this thing for 40 years! LOL Since I was 5 years old. I had an option several years back of some type of reversal.....and would have had to do catheterization. I preferred the urostomy.
If your tummy is an issue.....would laying down flat help you in any way? What about reclining in the bathtub? I am pretty sure they even make some type of bath pillow/wedge.
If there were some "leakage" you would be in the tub......it might be something to try.
I also think you might try the "stick on" type of appliances. I used to use the paste. It is very difficult to put it on quick enough.....to "beat" the ....well....you know what I mean.
Lots of the companies are very nice about giving you samples. If you wanted to try some you might ask........Good Luck! SheliaBaby
