In glazing the roof, beds of putty ...

In glazing the roof, beds of putty should first be placed on the glass rabbets of previously primed wood roof bars, and the glass pressed into the putty so that the entire space between the glass and the bars is filled with putty.

After each pane has been set in place it should be secured to the bars by means of zinc glazing nails: one nail at the bottom to prevent the glass from slipping down, and two more nails driven into the bars at either side to hold the glass firmly to the putty.

After the glass has been secured, excess putty can be cut away flush with the glass inside and outside.

It is poor practice to 'face putty' or place fillets of putty along the outside joints, as is usually done in glazing a window sash in a building.

Any first-quality outside paint may be used for painting the greenhouse.
