Old, cast iron or steel
radiators can be quite efficient and their replacement is not always necessary. However, it is difficult to consider
them as a decorative element of the interior. How
do you renew them?
Paints for radiators
Hiding old radiators
behind heavy curtains or furniture is not a good idea. We limit the flow of heat into the
interior. Therefore, if our cast
iron radiators do not look their best - it's time to renew them.
What paint to paint
radiators?
We can use metal paint,
however, pay attention to whether they meet very important parameters. After the first one should have
increased resistance to high temperature. Second
- do not turn yellow under the influence of heat. Another important feature is the high
hiding power and excellent adhesion to substrates.
Information on the
parameters of the given paint can be found on the packaging.
Paint manufacturers now
offer products designed for painting radiators. These are most often water-borne
paints, on an acrylic adhesive, but you can also get acrylic paints fast
drying, having excellent coverage properties.
How to prepare heaters
for painting?
Before we start painting
the radiators, we should prepare the substrate very carefully. It must be dry, vacuumed and
degreased.We clean the rust-covered ribs with a wire brush and remove old,
flaking paint coats. The rest
must be matted with sandpaper and carefully dusted.
Does painting the
radiators require priming?
Exposed metal fragments
of the radiator should be primed. Anticorrosive
primer paints are best suited for this.
Is it possible to paint
radiators during the heating season?
Unfortunately, we
usually remember about radiators when heating is turned on. Painting hot radiators is not a good
idea. The maximum temperature of
the substrate for applying paints to heaters is 30 degrees C. Higher causes too
fast drying, unevenness is created, and the coating is not durable.
Cast iron radiators are
best painted at room temperature, between the two layers leave about 4 hours to
dry. Therefore, if we decide now
to paint the radiators, turn them on, wait for them to cool down and then put
on the paint.
We can activate the
radiators after the coating has fully cured, after approx. 24 hours. The exception is fast-drying varnishes
- painted radiators can be turned on without having to wait for the coat to
dry.
