Hi everyone
I know it's been asked before but I can't seem to find the answer again
I have 6803 strips which I want to cut for the gable just wondering what is the best way to rejoin and waterproof again?
I will be putting them on a 25mm conduit frame
 
You'll need to strip back the silicon slightly, clean the pads very well to get the solder to stick and then after your done some heatshrink over the top of some neutral cure silicon. I personally prefer to use clear heatshrink.
 
if they are the coated with silicone (and not a sleeve) then I have found that soldering from the underside is so much easier.
After soldering them together, cover with silicone and slip some clear heatshrink over it and shrink.
 
If you have 30 LEDs per metre then any colour heatshrink is fine. I use black heatshrink even though the strips themselves are white. You can't tell at all as long as the heatshrink doesn't cover any of the lights themselves.

Ray Wu and probably other sellers of strip offer the same end caps that they use to waterproof the strips with their original cables but you can probably get away with silicone and heatshrink at the ends too.
 
I have found using these joiners to be helpful when either in a rush or you don't want to solder, but I would also seal them in heat shrink to minimise any chance of corrosion on the contact points

For the 6803 being a 4 wire then I would use these

Just make sure your terminals are clean on the strip before using
