Glazing or reglazing
a window
To replace it,
all the hard, crusty putty has to come out.
Some of it can
be picked out and some can be chiseled out. For the really
stubborn stuff, try a hot soldering iron. It softens the putty
so you can carve through.
With all the putty
removed, the old pane can be popped out.
With the old window
out, you can see the edge here that the new glass will rest
against. We have to clean all this out, to get it ready.
These windows are
held in place by metal push-points. They need to be plucked
out. Then a little sandpaper to clean up the groove.
tip:
Coat the exposed edge with linseed oil. It
prevents the wood from soaking up oil from the new glazing
compound.
Measure and mark
your glass with lines one-eighth of an inch smaller than the
window opening. That gives you some wiggle room if the sash
isn't square.
The easy way to
get the right-sized glass is to buy it pre-cut at the glass
store.
To cut your own
use a straight-edge and score the glass hard in one pass.
With the glass on a sheet of plywood, move the scored line
to the edge and snap. If cutting a curve, after scouring the
glass then tap lightly undet the glass along the scour.
If you measured
right, the glass will slip right in.
Apply puddy then
press in new glazing. Secure
it with new push points. Then apply puddy and finish with
puddy knife.
Let the putty cure
for a week or so. Then paint it to make it weatherproof.
