bottom corners on metal or butyl flashing of windows
read and reread Alberts roofing tutorial which is great for flashing, counterflashing windows.
one concept I dont see really explained to this slow learner is when your putting down a metal or butyl ,, in a "U" shape pan on bottom of window or door,,,,how do you get the flashing to turn that 4 way corner and lay flat to exterior wall without an ugly corner slice that admits water.????
otherwise a great article,,magnificent info any d-i-y ought to memorize.
do you use metal flashing, butyl sealant tape both together??
