The best time to repair all your weatherproofing jobs is a warm, dry day. Kevin
decides to repair a hole in brickwork (left from a heater flue).
A sheet of galvanised steel will be used to neatly do the job. The metal is
primed with etch primer, then painted with Rustguard. Kevin’s tip is to spray
with long, even strokes, without being too heavy handed with each coat. This
will avoid paint runs, and give an even finish.
The key to the job is a good weather seal, so Kevin chose Selley’s All Clear
because it’s paintable and flexible enough to move with changes in temperature.
The steel was then fixed to the wall with Tapcon fasteners. These screw straight
into the brickwork without plugs. Washers were used to space the steel out from
the brickwork, allowing space for the All Clear to be applied. Use plenty of
sealer in the joint to make sure water can get in, then smooth the sealer with a
finger wet with turps.
While he’s in the mood, Kevin searches out other weatherproofing problems. He
repaired a leaking roof with Selley’s Roof and Gutter, in a colour to match the
Kevin recommends pushing the nozzle, rather than dragging it, because you’ll get
more sealant into the joint. Smooth off the sealant before it has a chance to
develop a skin. While he’s up the ladder, Roof and Gutter is used to seal a
gutter inside and out – if you intend painting the gutter, do it before applying
the sealant because it’s not paintable.
This is a job you shouldn’t put off for a rainy day. Get those sealants ready
for a dry one!
