New shed glass advice

[rary]

Comeing late to this Marb, but think I would have used good quality anti mould sanitary silicon sealant, and if any algi did start showing a spray of weak bleach would possibly shift it, personally I would, on a warm dry day remove the glass clean off the putty and run a silicon bead round the window frame reposition the glass back in place then run silicon around the outside, using masking tape on the glass to give a clean finish, silicon can be smoothed using something like a plant label or similar dipped in water to stop the silicon sticking to it, again personally I wet my finger and use that to run round any job when using silicon, if it is tuffened glass or any glass avoid it sliding by fixing a couple of small blocks of wood onto the supporting strip of wood at the base of the window and gently lift up the glass and allow it to slide down till its resting on the wooden blocks this would allow a thin piece of wood to be used to ease up the glass till it can be removed, the job is a lot easier to do than to give lnstuction for

Well, after a few days seemingly water tight (the gaps were sealed) it is again letting in water. The shed may be porous but isn't all window wood in general ? As it took me hours to do I haven't the will to undo it all and re-apply silicone. Besides, last time I used silicone it also let in water with the perspex glass.

I can't win.

Marb you should be able to keep the inside of your hut dry, I understand what you are saying about the amount of work required if you were to remove the putty, so I would suggest you clean the glass on the inside and run a thick bead of silicone sealant round the edge of the window, make sure the silicone goes from the glass to the wood completely sealing the putty, this should give you a water tight seal, if you still get water in the problem is with the wood and to seal that I would recommend using an oil based gloss paint or PVA glue which should seal the wood

Thanks. I can cope with a little water at high rainfall but what I don't want is algae forming under the glass, making it look unsightly and impossible to remove without lifting the glass. The strange thing is, before I had this glass delivered I was just resting the perspex sheets on the wooden ledges with tacs at the sides to stop it popping out in wind. It didn't let any water in at all. This was months after I had taken out the old silicone that wasn't really doing it's job.

The water just seems to be getting between the putty where it meets the glass at the bottom. And yet putty is oild based and should be water tight. I am in discussion with Evostick about this too as it just shouldn't be happening between glass and putty.

After a light shower this morning its getting in even more. And yet a few days after I applied this it was water tight after a heavier rainfall which is proof that the putty is shrinking.
