Stabiliser is thinner and more penetrative but you can end up using gallons
of the stuff without any apparent improvement. Unless you have damp problems
I'd use PVA diluted at 1:4, which will stay closer to the surface and may
even form a film after a couple of coats.
Whatever gives you a surface that doesn't suck in the first coat of paint is
the one you need.
Thanks a lot for the advice, Stuart. Have duly drenched the house in
dilute PVA and am now well underway with the paint, which seems to be
taking well (although time will tell, I guess!)
Anyway... I now need to buy myself a new set of ladders, as the
current set (bought for a previous home) won't quite let me reach the
eaves, and at that height from the ground I'm not going to take any
daft risks. Question: given that the height of the eaves (ie the
highest point I need to get my paintbrush to) is 7 metres from the
ground, what minimum length of ladder do I need to buy? Just to be
clear, this is the apex of a 7m high, flat vertical end-wall of the
Should I be going for a double or triple extending ladder? As far as
I can see, the disadvantage of the former is that unless you have a
megabucks trade version with pulleys, it will be too long to extend
safely and easily; am I right? Will it flex more than the triple?
I expect someone's going to tell me a need a tower to be safe; really
want to avoid the expense of that if I can! To be honest I don't know
how I'd install a tower either, given constraints of the location.
Second reason for the second ladder is that I also need a roofing
ladder at the moment; my plan was therefore to obtain one of those
gizmos you attach to a regular ladder, (eg http://tinyurl.com/nete )to
convert it. Two birds with one stone, if you will. Does anybody have
experience of using one of these attachments, are they safe and OK to
use? I know a proper roofing ladder would be a better bet, but it
will only be for very occasional use.
Yes, I've considered hiring, but I will use this kit again
occasionally in the future and it makes economic sense to buy. Also,
it will be very much for weather dependent use, and IME as soon as you
contact HSS to hire any fair-weather tool, it's a cue for the heavens

Thanks for the tips Stuart.
Didn't get any replies about the roofing hook, so I went ahead anyway
and bought the above-described device from Screwfix, and thought it
might benefit others if I posted my experience!
First thing is that if anybody HAD responded, they'd probably have
pointed out that roofing hook attachments don't work well with a
conventional extending ladder; they work best with a single length of
ladder. Reason is two-fold.
Firstly, imagine an extended ladder lying flat - well, it doesn't, as
there's a 'step' in the middle between the two ladder lengths, which
prevents the load being distributed evenly on the tiles. Therefore
the lower length needs to have wooden battens wired to it to bring it
up to the same line as the upper ladder (does that make sense?)
Secondly, and more significantly, the stays on a normal extended
ladder are designed to resist load applied in a downward direction,
obviously. So it's easy enough to push the ladder up the roof on its
wheels, and then flip it over so the hook engages with the ridge. But
then what happens? If you're unlucky, the lower ladder then drops off
the bottom of the upper one under the influence of gravity. If you're
even unluckier, it waits till you're standing on it before gravity
takes effect! Either way, the upper ladder is then marooned half way
up the roof. (And no, I didn't get caught out by either pitfall.)
The solution, which I had to work out for myself - no mention of any
of these issues in the instructions (even to the effect of 'Not to be
used with extending ladders', which I would have expected) - was to
engage the lower ladder above, rather than below, the stay on the
upper ladder, so that it resists force applied in an upward direction
instead of downward. But of course the hooks on the stays now don't
engage over the rungs; therefore they have to be wired together
extremely securely, with plenty of thick gauge wire, so the whole
assembly stays put. Not ideal, and although I'm personally 100%
confident in the security of what I have set up, there is potentially
plenty of scope for causing oneself serious injury.
Having said all that, the roofing hook attachment itself is really
good and secure; fixed to a single ladder length I can't see it being
any worse than a proper roofing ladder.
Hope this helps somebody else in a similar position!
