Preparation
The Key To A Quality Interior Paint Job
As we enter the winter months, it
is a good time to start thinking about those interior painting
jobs you have been avoiding all summer!
And while it is very tempting to
buy a can of paint, pick up a brush or roller and simply start
painting, you'll just waste your money if you don't take the time
to prepare the surfaces properly!
According to Stephen Borrie,
Manager of the Paint Quality Institute in Australia and New
Zealand, paint performance depends on good paint adhesion and
paint adheres best to surfaces that are clean and sound.
“Inadequate surface preparation
is the single greatest cause of paint failure? he said. “Therefore
time spent in preparation will save you the time, money and effort
of fixing the job later.?/font>
So, how do you prepare the interior
for a paint job that will not only freshen up your home but add
value for years to come?
Clean thoroughly
Whether you are painting walls,
ceilings or trim, the starting point for any interior painting
project is to clean the surface you are about to paint.
Remove accumulated dust, dirt and
grime by scrubbing surfaces with a sponge and mild household
detergent solution.
For more stubborn stains such as
oil, grease or mildew, clean the surface with a scrubbing brush
and a stronger cleaning solution using ammonia or household
bleach. Alternatively, commercially available alkali cleaning
solutions such as sugar soap are often the most practical. These
solutions are toxic, so you must wear rubber gloves and safety
glasses and follow the instructions on the bottle.
After cleaning, rinse the surface
thoroughly with clean water and allow it to dry completely before
applying any type of primer or paint.
Remove loose and peeling paint
Using a scraper, remove as much of
the old loose, flaking or peeling paint as possible, then sand the
surface to feather or level off any rough edges and achieve a
smooth finish.
A note of caution! If you suspect
any of the old paint contains lead, stop work and ask your paint
store for advice on how to proceed.
Repair any damage
Cracks, gaps or small holes in
walls, doors or trim should be filled with a top quality paintable
water based sealant. Larger holes may need to be filled with
plaster.
Any old sealant that has cracked or
pulled away from the surface should be removed, the area cleaned
and new sealant applied.
Wherever you uncover bare timber,
it is recommended that you ‘spot?prime the area with an
acrylic interior primer or undercoat for an even finish when you
apply the topcoat.
Make final preparations
After all surfaces have been
cleaned, repaired and/or sanded, before applying any coatings you
should:
- Dull any glossy surfaces,
whether they are painted or not, with a fine grit sandpaper to
provide a key to which the paint will adhere;
- Give the surfaces a final dust
off; and
- Cover furniture and floors with
drop cloths to protect them from paint spatter and spills.
The proper attention to these
painting preliminaries will ensure that you can get on with your
paint job as smoothly as possible ?and not have to revisit the
job before you need to.
