Modest nails or spriggs as they are also known were so hammered down into the frame to hold the glass in place.
Opposite to what some people recollect, it's the nails that concord the glass in the frame and non the glazing putty. The glazing putty is simply there to seal the glass to the frame and prevent whatever draughts or water ingress into the frame.
This common misconception does lead some DIY'ers to attempt and replace panes of glass into frames but using the putty to agree it with not much success and more than often than not a smashed pane of drinking glass on the floor.
Fortunately, if the window putty was applied correctly in the first identify, it can concluding for many many years earlier it needs to be replaced, and so thankfully, this shouldn't exist a job that needs to be done too often.

Keep tapping the hacking knife down towards the frame and the chunks will ping off. You volition soon get used to how hard y'all tin can hit it.
Which ever way your frame is lying, always hit down towards the frame. Never striking downwards towards the glass or you lot will smash it.
In one case y'all take removed a chunk of putty you should exist able to see how deep information technology is and where the frame is so that yous know exactly how deep you can hit the knife downwardly without accidentally chopping into the frame.
Continue chopping away the old putty along the surround, ensuring that you lot get right downwards into each corner.

Motility yourself around the window as you chop, don't exist tempted to contort yourself into some awkward position as this is how accidents happen and damage is caused.
Carefully work your way around the perimeter of the drinking glass, chopping out whatsoever and all putty with the hacking pocketknife equally you go until all putty has been removed.
To soften any hard putty you tin use a oestrus gun. Heating the putty up volition cause it to go soft and make removing it much easier.
Run the heat gun over the putty from side to side, beingness conscientious not to concentrate any rut in 1 spot for too long equally if glass gets too hot it will crack. You can use some thick pieces of timber cut to length to shield the glass from the direct estrus from the gun.
In one case soft y'all should then exist able to chop information technology out.

Step 7 – Employ new Putty
Once any nails or pins have been fixed in identify to agree the glass in the frame, it's at present time to apply some putty.

Once information technology'south dainty and workable mix the putty thoroughly to make sure all the oil is mixed throughout the putty evenly as it tends to separate when left in the tub for a while.
To apply the putty around the window frame, roll a section of it out into a "sausage" so that it'due south about ten-12mm in diameter and and so place it along ane edge or utilize a putty knife to scoop it from the pot and apply it to the groove.
Echo this until y'all have covered the entire internal border.

Timber chaplet or quadrant can exist used in place of glazing putty
As with the putty, all corners are mitre cut to not merely look neat but to as well provide a good seal.
Before whatever mouldings are fixed in place on a window a thin bead of silicone is run around the rabbet groove to create a seal and then the bead is fixed in place using pocket-sized nails or brads.
As with the putty, to get the best and most long lasting terminate, the dewdrop or quadrant will need painting.
