I'm back with another thrilling tale of home improvement.
|
|
|
|
When I first moved in, there wasn't a loft ladder installed. So I had to use an
|
|
outdoor ladder to access the loft. For some odd reason they installed the loft
|
|
hatch in the bathroom which is inconvenient and risks exposing the loft space to
|
|
moisture.
|
|
|
|
Installing a proper loft ladder and taking steps to reduce moisture was
|
|
therefore high on my priority list.
|
|
|
|
Lofts are weird and bespoke so I was a bit nervous about buying an off-the-shelf
|
|
ladder but I knew it would be cheaper than paying a professional.
|
|
|
|
I opted for the "Werner 3 Section Easy Stow Loft Ladder" from Argos.
|
|
|
|
When I was about half-way through the installation, calamity struck and I
|
|
realised that the existing hatch, which opened inward, would be blocked from
|
|
closing by the ladder.
|
|
|
|
To overcome this problem, I would need to construct a new hatch that opened
|
|
outward and that would hang down when the ladder was extended.
|
|
|
|
This turned into quite a side-quest and took far longer than the installation of
|
|
the ladder itself. However it presented an opportunity to address the moisture
|
|
risk.
|
|
|
|
I was mindful of moisture degrading the hatch-door so I did some research and
|
|
realised that I needed what's called _marine_ plywood. Basically, plywood
|
|
treated to withstand moisture better than standard ply.
|
|
|
|
B&Q offer a cutting service where the first five cuts are free if you buy your
|
|
wood from them. So I ended up having to buy a very large piece of marine ply and
|
|
had it cut down to the size of the hatch. Alas, my measurements were off and it
|
|
was too small. So I had to try again with the spare wood and a hand-saw. This
|
|
time I was overly conservative and it was slightly too large, so I spent a long
|
|
time using a surform plane to shave it down to size.
|
|
|
|

|
|
|
|
Finally, it fit the hatch nicely. Marine ply on its own provides some protection
|
|
from moisture but to give it the best chance I bought some B.I.N primer which is
|
|
designed to protect wood in moist environments like kitchens and bathrooms.
|
|
|
|

|
|
|
|
After applying the primer I applied two coats of standard satin wood in
|
|
brilliant white.
|
|
|
|

|
|
|
|

|
|
|
|
Whilst the hatch did fit, there were annoying gaps on the left and the right
|
|
side. This is the sort of thing that gets ahold of me and burrows into my
|
|
subconscious because I am both a perfectionist and a highly average handiman.
|
|
|
|
But then I had a brainwave and realised I could apply some white self-adhesive
|
|
draft excluder to both hide the gaps and reduce draught/moisture getting into
|
|
the loft.
|
|
|
|

|
|
|
|

|
|
|
|
Also, the caulking around the hatch architrave was cracked and moist. So I
|
|
scraped it out and applied new caulk designed for bathrooms. I didn't bother to
|
|
paint over so it doesn't look amazing but the bathroom ceiling is already in a
|
|
bad way so I will leave that until I have it replastered and properly treated.
|
|
|
|

|
|
|
|
With the hatch problem finally resolved I could finish installing the ladder.
|
|
This was mostly straightforward. With the ladder extended the hatch is very
|
|
small and I have to maneuvre myself sideways at the top to get through. Still,
|
|
this is much more convenient than bringing a dirty ladder into the bathroom
|
|
every time I want to access the loft.
|
|
|
|

|
|
|
|
Overall, this project probably cost more (£201) than it would to just have a
|
|
specialist install it but, on the plus side, I learned about marine ply (and
|
|
have plenty spare) and B.I.N which seems to be the gold standard of primers. I
|
|
also now have an intimate and god-like knowledge of my loft hatch and how many
|
|
people can say that these days?
