    I have been remaking/repurposing a French made pair of French doors, they must have been 20 years old and whatever compound the sealed glazing units were set onto was superb because it was still really sticky, it was the devils job to remove the units and the remaining compound, bits of it are still sticking to my boots and getting transferred to the flooring everywhere.

    So I want to find either the same or something equally as good, I have some mastique vitrier from a long while back (huile de lin based) but that has gone solid in the sealed tub.

    Anything that you can recommend preferably that can be applied with a mastic gun.

    I need a really good seal and one that remeains stuck because I forgot to machine the rain groove that sits under the glazed units on a couple of the muntins, they will have the drain holes but I would rather the water cannot find its way down there as that is what causes the misted up units you see so often in the UK.

    Having had the problem of misting up of DG units in our last house in the UK, because the d*ckhead builder puttied the units into the wooden frames as if the units were conventional single panes, I wouldn’t use mastic or putty to retain DG units.

    I did start to replace the DG units after about 20 years but it proved to be such a PITA job as the frames were not in good condition so we had all doors and windows in the house replaced with PVC.

    (Cue squeals of horror from the anti-pvc window brigade – but they were brown woodgrain on the outside and white on the inside – very difficult to tell them from hardwood unless up close)

    This -apparently-is the correct way to fit DG units into wooden frames.

    Our current house has factory made hardwood windows with DG units fitted from the inside, and there is no seal or mastic between the glass and the frame on the outside, but has a 1/4″ drain louvre machined into the full length of the rail at the bottom facing out, plus there is a epdm sealing strip on the inside joint between the frame and glass.

    Thats great, its actually what I was going to do from having thought long and hard but its great to have it confirmed and above all the diagram to avoid any misinterpretation.

    The key things that are missing on all my Alu and UPVC windows in the UK are the glazing blocks, a rebate and drainage holes for any water ingress, they use a rubber seal outside which always leaks on the mitred corners which themselves shrink back, no drainage so the sealed units then sit in a puddle of water.

    I used Brico-depot hardwood windows on my pied a terre 11 years ago, they have all the elements plus the beads of silicone and none of them have misted.

    I was never going to “bed” the units on the mastic, just use it to glue them to the front rebate, I have since discovered Butyl glazing tapes which used in conjunction with silicone should do the job, I find putty or mastic hard to work with by hand.

    I’d avoid silicone unless you never want them out again?

    My current fave is this stuff:  http://www.caravan-components.co.uk/Caravan-Sealant-Mastic-IDL99-Cream-in-400ml-Tube

    I’ve used it to bed ceramic plumbing, shower doors etc.

     

    I originally had it for a ‘van, but it also found use on the rear lights of my classic Scooby.
