Hi All,
I have timber windows and door frames that have previously been treated with sikkens externally and nothing applied to the internal frames. I need to re-do the external timbers and seek your advice re the internal frames.
Is sikkens the best the best product to use?
If some of the sikkens drips onto the plaster - how do I manage the spill?
Is there a less toxic product you would recommend?

Many thanks in advance!

Dom
