Linseed oil glazing putty drying time

[Adam78]

Hi,

I have a window which needs to be putty pointed from the outside. I note linseed oil glazing putty can take anything between 7-21 days to dry before it can be painted.

Does it matter if it rains within this time period, in other words will rain have any negative impact on the putties performance?

Adam78, good evening.

Linseed Putty will repel water even when just applied, trick is to get the surface finish of the putty as smooth as possible, if you can spend some tile on the smoothing operation, I used to love watching a glazier whizzing around a window.

Use thin narrow small nails, my preference was hardboard nails, or "sprigs" to ensure the glass is retained until the putty sets.

As for painting, and timing? weather / temperature / sunshine dependent / age of putty Etc.

you will find that the putty develops a "skin" after a few days, you can carefully paint at that stage, but? if you paint too early, your painting can wrinkle the slowly forming skin on the putty.

Keep an eye on the putty over several days following application, Birds love the putty and will peck away quite happily at your nice smooth putty finish.

I now use dryseal mp glazing sealant as it dries in a few hours.

Its sticky like silicone though, takes a fair bit of practice!

Hi Ken,

Can you paint over linseed oil putty using a water based paint. I'll be using the zinsser exterior all coat which is water based?

Adam78, good evening again.

Must admit totally up front I have no direct knowledge of zinsser exterior all coat, and putty, sorry about that.

My original statement as above stands, normal putty will form a "skin" over time, and if you are over zealous with a paint brush you may find that the putty's skin peels off when the paint brush passes over the new putty surface.

As an aside, if you can ensure that the top edge of the putty does not rise above the internal line of the frame, if the putty does rise over the [so called] glazing check, you will see an uneven line of putty above the frame, not easy to describe without a sketch or waving your hands around, not much use in this sort of reply??
