SEALING THE GREENHOUSE
When all the polycarbonate sheets are installed, take a
tube of
CLEAR SILICONE SEALANT
(
A
) and seal all the
panels that fit into the aluminum
tracks on the
top, the bottom, the inside and the outside. In this way,
you can keep out most of the moisture from the end of the
panels. If this sealing process is not done, water may sit in
the bottom and fill the inside of the panels and grow
algae.
1. Unscrew the plastic nozzle on the tube of
silicone sealant.
2. Cut the top of the tube.
3. Screw on the plastic nozzle again.
4. Cut approximately 1/8” off the end of the plastic
nozzle at a 30-degree angle.
5. Put the tube into the caulking gun. When using
the gun, squeeze the handle slowly.
6. Wherever the polycarbonate sheets are sittng
in a side / base track or aluminm “ ”. Also seal
the inside of the “ ” on the ends and sidewalls
because greenhouse humidity runs down the
panels into the “ ” track.
7. Seal the vents before you slide them into place.
Seal the places where the panes fit into the door
frame bar and the “ ” under the above door
angle.
