bagging film and amastic

the bag
the bagging film is about 8$ per meter
it is wide enough to fold on its side so you only seal one end and one side
you use yellow mastic to do this, yellow mastic is a permement mastic.
black mastic will peel off the plastic easily, this is good for the open end.
you need a clean floor and space and layout the plastic on the floor.
use the yellow mastic and carefully stick the strip around one end and up the side of the bag
leave the paper covering on the mastic
fold the bag back over in place and slowly peel back the paper as you slide you finger along and stick down the bag

the floor must be clean, look after the bag it will do many boards if you are careful with it and dont leave dry fiberglass bit on your rocker table and bagging surface. carefully fold thebag away into a safe place when finished

seal the end with black mastic so you can remove it and reseal for the next board.
if you get pinhole leaks mark them with a permenent marker so you can find them later.
when you seal the end down whilst bagging a board , make sure the surface is flat and extends past the width of the bag

bagging supplies can be obtained from boatbuilding suppliers that deal in composites
and they are pretty cheap if you look after them
a 40$ bag will do 20 or 30 boards if you are carefull
